All other embodiments that can be derived by one of ordinary skill in the art from the embodiments in one or more of the specification without inventive faculty are intended to fall within the scope of one or more of the specification.

One or more embodiments of the present disclosure provide a block chain-based vehicle parking image storage method, apparatus, and system, where after a user uses a shared vehicle, the user uploads a vehicle parking image to a cloud server through a user terminal, so that the cloud server can perform trusted storage on the vehicle parking image uploaded by the user terminal, and thus, the corresponding vehicle parking image can be subsequently retrieved at any time for abnormal parking tracing.

Fig. 1 is a schematic view of an application scenario of a block chain-based vehicle stop image storage system according to one or more embodiments of the present disclosure, as shown in fig. 1, the system includes: the system comprises a user terminal and a cloud server, wherein the user terminal can be a shooting device terminal deployed on a user side, can be a mobile terminal such as a smart phone and a tablet personal computer, and can also be a special shooting device; the cloud server can be a background server used for checking and storing the stop image information uploaded by the user terminal, a block chain used for storing the stop image information is deployed in the cloud server, and the specific process of vehicle stop image storage based on the block chain is as follows:

(1) the method comprises the steps that a user terminal obtains parking image information of a target shared vehicle to be uploaded, wherein after a user uses the shared vehicle to finish travel service and the shared vehicle is parked in a preset area, the user terminal (such as a smart phone) needs to actively shoot parking image information of the shared vehicle used by the user terminal, and the user triggers a designated control on the user terminal to request to upload the parking image information to a service terminal;

specifically, the parked shared vehicle can be shot through a camera on the smart phone, after a user terminal detects an uploading request of a user for a certain target image, the target image can be determined as the parked image information of the shared vehicle needing to be uploaded to the cloud server, and the target image can be the image information of the shared vehicle currently parked by the user;

specifically, an information processing module SDK in the user terminal detects whether a parking image uploading request exists in real time, if so, the corresponding parking image information is determined as the parking image information of the target shared vehicle to be uploaded, and the parking image information is transmitted to a safety hardware module;

(2) the user terminal signs the obtained parking image information through the safety hardware module based on a pre-generated private key to obtain signed parking image information; the signed docking image information is transmitted to an information processing module, wherein if the user terminal is a mobile terminal such as a smart phone and a tablet personal computer, the Secure hardware module can be a functional module for running a program developed based on TEE, and if the user terminal is a special shooting device, the Secure hardware module can be a Secure Element (SE) unit, and functions such as Secure storage of private information and Secure execution of important programs can be provided through the Secure hardware module;

specifically, the user terminal may include: the system comprises a shooting module, an image acquisition module, a safety hardware module and an information processing module SDK, wherein the image acquisition module can belong to the information processing module, namely the image acquisition module and the information processing module are the same functional module, and each user terminal is provided with a respective safety hardware module; the security hardware module randomly generates a group of asymmetric key pairs, namely a public key and a private key, by using an asymmetric encryption algorithm in a key pair generation stage, the private key for information signature is only locally stored in the security hardware module, and the public key for information signature is transmitted to the cloud server, so that the cloud server performs signature verification on docking image information uploaded by a corresponding shooting equipment terminal by using the public key;

(3) the information processing module in the user terminal uploads the signed docking image information to the cloud server, so that the cloud server conducts information signature verification on the signed docking image information and stores the docking image information;

(4) the cloud server obtains a public key corresponding to the parking image information after receiving the signed parking image information, utilizes the public key to verify the parking image information, concretely, decrypts the signed parking image information by utilizing the public key, judges whether the parking image information passes the verification according to a decryption result, if the decryption is successful, the verification is passed, and if the decryption is unsuccessful, the verification is not passed;

(5) if the cloud server determines that the verification tag passes, the docking image information is stored in the block chain, wherein the block chain technology has non-tamper property, so that the docking image information written in the block chain can be guaranteed not to be tampered, and the credibility and the safety of data are guaranteed; meanwhile, the docking image information stored in the block chain can be directly used as traceable evidence subsequently;

in the storage process of the parking image information, after a user uses a shared vehicle, the user terminal uploads the vehicle parking image to the cloud server so that the cloud server can reliably store the vehicle parking image uploaded by the user terminal, and therefore the corresponding vehicle parking image can be called at any time for abnormal parking tracing, meanwhile, a double protection mechanism of information tagging and block chain storage of a service end is carried out through a safety hardware module of the user terminal, and the credibility, the safety and the tamper resistance of the vehicle parking image are improved;

in addition, the user is required to actively shoot and upload the parking images of the shared vehicles used by the user aiming at the completion of the use of the shared vehicles each time, and due to the fact that the process of uploading the parking images of the vehicles is added, the user can be urged to carry out the compliant parking on the shared vehicles used by the user according to the restricted parking standard to a certain extent;

furthermore, the user can be required to upload the parking image information of the shared vehicle to be used so as to monitor the parking condition of the previous user on the shared vehicle; specifically, the stop image information to be uploaded may also be a vehicle stop image shot before the user terminal executes the service order, and correspondingly, after receiving the signed stop image information, the cloud server determines the identification information of the historical user terminal corresponding to the latest finished service order of the target shared vehicle, and stores the stop image information passing the signature verification and the identification information of the historical user terminal into the block chain.

Fig. 2 is a first flowchart of a block chain-based vehicle stop image storage method according to one or more embodiments of the present disclosure, where the method in fig. 2 can be executed by the user terminal having the security hardware module in fig. 1, and as shown in fig. 2, the method at least includes the following steps:

s201, obtaining parking image information of a target shared vehicle to be uploaded, wherein after a user finishes travel service by using the shared vehicle and the shared vehicle is parked in a preset area, the user needs to actively shoot the parking image information of the shared vehicle used by the user through a user terminal (such as a smart phone), and the user uploads the parking image information to a service terminal by triggering a specified control on the user terminal to request;

s202, signing the acquired parking image information by using a security hardware module based on a pre-generated private key to obtain signed parking image information, wherein the private key corresponds to the user terminal one to one;

specifically, after acquiring image information requested to be uploaded by a user, a user terminal does not directly upload the image information to a server, but performs signature processing on the image information, wherein the image information is shot by a shooting module to obtain parking image information of a shared vehicle, and an information processing module acquires a vehicle parking image and triggers a safety hardware module to perform signature processing on the vehicle parking image after detecting an image uploading request of the user; the safety hardware module transmits the signed vehicle parking image to the information processing module;

the secure hardware module may be a module running a Trusted Execution Environment (TEE) because the secure hardware module can provide functions such as secure storage of private information, secure Execution of important programs, and the like. Before the information is stored in the block chain, the docking image information is signed by using the security hardware module, so that the security and the credibility of the docking image information at a client and the security and the tamper resistance in the process of transmitting the docking image information to the cloud server can be ensured;

s203, uploading the signed parking image information to a cloud server so that the cloud server can carry out signature verification on the signed parking image information and store the parking image information passing the signature verification into a block chain;

specifically, the information processing module receives signed docking image information transmitted by the security hardware module and uploads the signed docking image information to the cloud server;

in addition, in specific implementation, in order to play a role in restricting the uploading of images for a user by considering the fact that the user may not actively upload the vehicle stop images, the user is allowed to end the service order initiated by the user only when the vehicle stop images uploaded by the user are received;

specifically, after detecting a service order ending request of the user terminal, the cloud server judges whether stop image information of a shared vehicle corresponding to the service order is received or not, if yes, the cloud server responds to the service order ending request, and if not, prompt information for uploading stop images is sent to the user terminal, so that the user terminal is ensured to upload corresponding vehicle stop image information according to requirements.

In addition, in order to further improve the security of the uploaded information, the signed docking image information can be uploaded to a cloud server through a trusted channel, so that the information is prevented from being intercepted and tampered in the information transmission process;

specifically, after receiving the docking image information uploaded by the user terminal, the cloud server performs signature verification processing on the docking image information, and if the signature verification is passed, the docking image information is stored into the block chain, so that the process of information signature verification is added before the information is stored into the block chain, and the data stored into the block chain can be ensured to be credible;

the block chain technology has non-tamper property, so that the docking image information written in the block chain can be guaranteed not to be tampered, and the credibility and the safety of data are guaranteed; meanwhile, the docking image information stored in the block chain can be directly used as traceable evidence subsequently.

In one or more embodiments of the present description, after a user uses a shared vehicle, the user terminal uploads a vehicle stop image to the cloud server, so that the cloud server can perform trusted storage on the vehicle stop image uploaded by the user terminal, and thus, the corresponding vehicle stop image can be called at any time for performing abnormal stop tracing, and meanwhile, a dual protection mechanism of information tagging and block chain storage of the service end is performed through a security hardware module of the user terminal, so that the credibility, the security and the tamper resistance of the vehicle stop image are improved.

In a specific embodiment, as shown in fig. 3, a schematic diagram of a first interaction process between a user terminal and a cloud server is provided, specifically:

s301, a user terminal collects parking image information of a target shared vehicle to be uploaded through a shooting module, wherein a user can request to upload the parking image information by triggering a specified control on the user terminal;

s302, after monitoring the triggering operation of a user for a specified control, an information processing module acquires docking image information to be uploaded, wherein the information processing module is provided with a corresponding Software Development Kit (SDK);

specifically, in order to ensure the authenticity of the parking image uploaded by the user, the authenticity of the vehicle parking image requested to be uploaded by the user can be verified, and then the parking image information passing the authenticity verification is transmitted to the safety hardware module, so that the safety hardware module performs information tagging processing;

s303, the information processing module sends docking image information to be uploaded to the safety hardware module;

s304, the safety hardware module signs the parking image information by using a pre-generated private key to obtain the signed parking image information;

s305, the safety hardware module sends the signed docking image information to the information processing module;

s306, the information processing module uploads the signed docking image information to a service module server in a cloud server;

s307, the service module server performs signature verification on the signed docking image information;

s308, the service module server stores the stop image information passing the signature verification into the block chain.

Further, considering that the vehicle parking image requested to be uploaded by the user may have poor authenticity, the user may request to upload a parking image previously captured for the target shared vehicle, and therefore the parking situation of the shared vehicle used by the user this time cannot be truly reflected, based on this, before uploading the parking image of the shared vehicle to the service end, the authenticity verification is performed on the vehicle parking image, that is, the authenticity of the geographic position information and the time information of the vehicle parking image requested to be uploaded by the user is automatically identified, so as to determine whether the vehicle parking image requested to be uploaded by the user is the latest captured parking image, specifically:

as shown in fig. 4a, the step S201 of acquiring parking image information of the target shared vehicle to be uploaded specifically includes:

s2011, after detecting an upload request of a user for a target image, acquiring current shooting scene information, where the current shooting scene information includes: shooting time information and/or shooting position information;

s2012, judging whether the shooting scene information carried in the target image is matched with the acquired current shooting scene information;

if the judgment result is yes, S2013 is executed, and the target image is determined as the parking image information of the target shared vehicle to be uploaded;

if the judgment result is negative, executing S2014, and generating and displaying prompt information for representing that the user is requested to upload the latest shot image;

specifically, shooting scene information carried in a target image requested to be uploaded by a user is compared with current shooting scene information acquired in real time;

if the matching degree of the two images is larger than a preset threshold value, the target image which is requested to be uploaded by the user is the latest vehicle parking image shot by the user;

if the matching degree of the two images is smaller than or equal to the preset threshold value, it is indicated that the target image requested to be uploaded by the user is not the vehicle parking image which is shot by the user latest, namely the target image may not truly reflect the parking condition of the shared bicycle used by the user at this time.

Further, considering that the vehicle parking image requested to be uploaded by the user may have poor authenticity, the user may also request to upload the parking image of another shared vehicle around the shared vehicle used by the user, that is, there may be a situation that the user requests to upload the parking image of the shared vehicle not parked by the user, and therefore, the parking situation of the shared vehicle used by the user at this time cannot be truly reflected, based on this, before uploading the parking image of the shared vehicle to the server, the authenticity verification is performed on the vehicle parking image, that is, whether the unique identifier of the vehicle parking image requested to be uploaded by the user is accurate or not is automatically identified, so as to determine whether the vehicle parking image requested to be uploaded by the user is the parking image of the shared vehicle used by the user, specifically:

as shown in fig. 4b, the step S201 of acquiring parking image information of the target shared vehicle to be uploaded specifically includes:

s2015, after an uploading request of a user for a target image is detected, extracting a first vehicle identifier from the target image; determining a second vehicle identifier in a service order aimed at by the uploading request, wherein the first vehicle identifier can be obtained by identifying a vehicle graphic code in a target image, and the second vehicle identifier is a unique vehicle identifier corresponding to the unlocking request of the user terminal;

s2016, judging whether the first vehicle identifier is consistent with the second vehicle identifier;

if the judgment result is yes, S2017, determining the target image as the parking image information of the target shared vehicle to be uploaded;

if the judgment result is negative, S2018, prompt information representing that the user is requested to upload the vehicle image used by the user is generated and displayed;

specifically, a vehicle unique identifier in a target image uploaded by a user request is compared with a vehicle unique identifier corresponding to a current business order; namely, the unique vehicle identifier in the ongoing business order of the user is the unique identifier of the shared vehicle used by the user himself, and the unique vehicle identifier and the unique identifier need to be consistent;

if the comparison result shows that the identifiers are consistent, the target image which is requested to be uploaded by the user is the parking image of the shared vehicle used by the user;

if the comparison result shows that the identifiers are not consistent, the target image which is requested to be uploaded by the user is not the parking image of the shared vehicle used by the user, namely the target image possibly cannot truly reflect the parking condition of the shared vehicle used by the user at this time.

Further, considering that there may be a situation of falsification of the environment information of the vehicle parking image, in order to further ensure the authenticity of the parking image information stored in the block chain, at the client, the environment information marking on the vehicle parking image is introduced, and correspondingly, at the background server, the step of performing environment verification on the parking image information is introduced, and only the parking image information that passes the signature verification and the environment verification is stored in the block chain, based on this, as shown in fig. 4c, the above S203 uploads the parking image information after signature to the cloud server, so that the cloud server performs signature verification on the parking image information after signature and stores the parking image information that passes the signature verification into the block chain, specifically including:

s2031, carrying out environment information marking on the signed docking image information to obtain the docking image information after the environment marking;

specifically, a corresponding relation between the signed docking image information and the environment information is established, the signed docking image information and the corresponding environment information are bound, and the combination of the signed docking image information and the environment information is determined as the docking image information marked by the environment;

in addition, the obtained combination of the parking image information of the shared vehicle and the corresponding environment information can be directly signed to obtain the signed parking image information marked by the environment;

s2032, uploading the environment marked docking image information to a cloud server so that the cloud server can perform signature verification and environment verification on the environment marked docking image information, and storing the docking image information which passes the signature verification and the environment verification into a block chain;

specifically, the information processing module receives the signed docking image information transmitted by the security hardware module, performs environment information marking on the docking image information, and uploads the environment-marked docking image information to the cloud server;

specifically, before uploading the docking image information to the cloud server, the user terminal not only signs the docking image information, but also marks the docking image information, so that after receiving the docking image information uploaded by the user terminal, the cloud server not only needs to check the signing processing of the docking image information, but also needs to perform environment verification processing on the docking image information, and if the signing processing is passed and the environment verification is passed, the docking image information is stored into the block chain, so that the data stored into the block chain can be further ensured to be credible and real.

For the process of marking the environmental information, the S2031 performs the environmental information marking on the signed docking image information to obtain the docking image information marked with the environmental information, and specifically includes:

the method comprises the following steps of firstly, obtaining current environment information of a target sharing vehicle, wherein the current environment information comprises: at least one item of satellite positioning information, network equipment identification and communication network identification;

specifically, the satellite positioning information may be GPS information, the network device identifier may be identification information of a base station used for communication, and the communication network identifier may be identification information of a wireless communication network, for example, the wireless communication network may be wifi;

secondly, performing environment marking on the signed parking image information based on the obtained current environment information to obtain environment marked parking image information;

specifically, the signed stop image information and the corresponding current environment information are subjected to information binding, and a set of the signed stop image information and the corresponding current environment information is determined as the stop image information marked by the environment.

Specifically, to the signature verification process of the cloud server to the docking image information, specifically:

(1) acquiring a public key corresponding to the parking image information to be signed and verified;

specifically, determining a target terminal identifier of a user terminal uploading signed parking image information; the method comprises the steps of obtaining a public key which is stored in advance and corresponds to a target terminal identification, wherein the public key is recorded by a cloud server requested by a user terminal with the target terminal identification in a stage of generating an asymmetric key pair in a security hardware module;

(2) the obtained public key is used for carrying out signature verification on the received signed parking image information;

specifically, if the landing image information of the plaintext can be obtained by decryption based on the public key, the signature verification result is determined to be that the signature verification is passed; if the landing image information of the plaintext can not be obtained through decryption based on the public key, determining that the signature verification result is that the signature verification fails;

specifically, to the environment truth checking process of the cloud server to the image information of berthing, specifically:

(1) acquiring environment information corresponding to docking image information to be subjected to environment verification, wherein the environment information comprises attribute values of a plurality of environment attribute parameters, and the environment attribute parameters can be environment parameters representing geographic positions, for example, the environment attribute parameters can be satellite positioning information, network equipment identifiers or communication network identifiers;

specifically, environment information corresponding to parking image information to be subjected to environment verification is analyzed from the parking image information subjected to the environment marking, wherein the environment information is current environment information of a target shared vehicle embedded when the user terminal performs the environment marking on the parking image information;

(2) determining geographic position information corresponding to the attribute value of each environment attribute parameter;

specifically, if the environment attribute parameter is satellite positioning information, determining the current longitude and latitude information locked by using a GPS positioning technology as corresponding geographic position information, if the environment attribute parameter is a network equipment identifier, determining the longitude and latitude information where the network equipment is located as the corresponding geographic position information, and if the environment attribute parameter is a network communication network identifier, determining the current longitude and latitude information covered by a wireless communication network as the corresponding geographic position information;

(3) if the determined plurality of geographical position information meet the preset conditions, determining that the environment verification result is that the environment verification passes;

specifically, considering the situation that geographical position information corresponding to each environmental attribute parameter may have a deviation, if the position distance of the plurality of pieces of geographical position information is smaller than a preset threshold, determining that the plurality of pieces of geographical position information satisfy a preset condition; aiming at the condition that a plurality of geographic position information are kept consistent, namely the position distance is zero, any one of the satellite positioning information, the network equipment identifier and the communication network identifier is not modified;

for example, if the geographic position information corresponding to the satellite positioning information is a geographic position 1, if the geographic position information corresponding to the network device identifier is a geographic position 2, if the geographic position information corresponding to the communication network identifier is a geographic position 3, if the distance between every two of the geographic position 1, the geographic position 2 and the geographic position 3 is smaller than a preset threshold value, it is determined that the environment authentication result is that the environment authentication passes, and thus, if the attribute value of any one environment attribute parameter is forged or tampered, the environment authentication result is recognized in the environment authentication process;

in addition, in specific implementation, whether the environment verification passes or not can be determined by comparing the environment information analyzed from the docking image information after the environment mark with the environment information stored in advance for the user terminal.

In order to further ensure the authenticity of the vehicle stop image stored in the block chain, at the client, the environment information mark is introduced to the vehicle stop image, and correspondingly, at the background server, the step of performing environment verification on the vehicle stop image is introduced, and only the vehicle stop image passing through the signature verification and the environment verification is stored in the block chain, based on this, the above S901 receives the stop image information after the signature of the target shared vehicle, and specifically includes:

receiving parking image information after environment marking of a target shared vehicle, wherein the parking image information after the environment marking is obtained by performing environment marking on the signed parking image information;

specifically, if the parking image information acquired from the blockchain is encrypted data, the encrypted data needs to be decrypted by using corresponding key information to obtain the parking image information of the plaintext, then, required key features are extracted from the parking image information of the plaintext, abnormal parking identification is performed on the key features, if the identification result meets a preset condition, it is determined that the parking of the shared vehicle to be traced is abnormal, and corresponding punishment is performed on a user terminal uploading the parking image information;

for example, if the recognition result shows that the vehicle is not parked in the preset parking area, determining that the recognition result meets the preset condition;

for another example, if the recognition result shows that the vehicle is not parked according to the preset normal parking posture (for example, the vehicle is in an inclined or inverted state, etc.), it is determined that the recognition result satisfies the preset condition.

correspondingly, the certificate record request carries encrypted certificate information, and the encrypted certificate information is obtained by encrypting the terminal identifier and the digital certificate containing the public key by using the distributed encryption key.

The recording of the digital certificate corresponding to the user terminal and including the public key specifically includes:

acquiring a decryption key corresponding to a user terminal;

carrying out credibility verification on the encrypted certificate information by using the acquired decryption key;

and if the credibility is verified to be passed, recording a digital certificate containing the public key in the certificate information corresponding to the user terminal.

and distributing the graphic code to the user terminal in advance so that the user terminal scans the graphic code to obtain the encryption key.

Specifically, after receiving a registration request of a user terminal, if the user terminal passes the registration verification, the cloud server sends a randomly distributed graphic code to the user terminal, so that the user terminal can encrypt a digital certificate requested to be recorded by using an encryption key corresponding to the graphic code, and thus, the cloud server can identify whether the user terminal requested to record the digital certificate is a registered trusted user terminal by decrypting received certificate information, and further improve the storage accuracy of the digital certificate;

in addition, in order to improve the security of the encryption key, a dynamic graphic code can be distributed to the registered user terminal, namely the graphic code can be a dynamic graphic code such as a dynamic two-dimensional code, and the cloud server distributes a corresponding dynamic two-dimensional code to the user terminal after receiving a graphic code distribution request of the user terminal;

specifically, the encryption key is used for the shooting device terminal to prove the trusted identity of the shooting device terminal to the server, so that the situation that an untrusted illegal device obtains the digital certificate through an improper channel is avoided.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (computer unified Programming Language), HD call, JHDL (Java Hardware Description Language), Lava, Lola, HDL, las, software, rhyd (Hardware Description Language), and the like, which are currently used in most popular languages. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.
