Various communication client applications, such as shopping applications, social platform applications, video and audio playing applications, etc., may be installed on the terminal devices 101, 102, 103. The user can enter an account number and a password through the terminal devices 101, 102, 103 to log in to these client applications.
The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices including, but not limited to, smart phones, tablet computers, e-book readers, car computers, laptop portable computers, desktop computers, and the like. When the terminal apparatuses 101, 102, 103 are software, they can be installed in the electronic apparatuses listed above. It may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services) or as a single piece of software or software module. And is not particularly limited herein.
The server 105 may be a server that provides various services, such as a backend server that saves an account number and a password of an application installed on the terminal apparatus 101, 102, 103. The background server may store the account and the password input by the user, and feed back the account and the password to the terminal devices 101, 102, and 103 when the user queries.

When the server 105 is hardware, it may be implemented as a distributed server cluster composed of a plurality of servers, or may be implemented as a single server. When the server 105 is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be noted that the method for storing data provided by the embodiment of the present application is generally executed by the server 105. Accordingly, means for storing data is typically provided in the server 105.
In some specific applications, the system architecture 100 may further include a blockchain distributed storage server, not shown, for storing the data by using a blockchain technique.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for storing data in accordance with the present application is shown. The method for storing data of the embodiment comprises the following steps:
In this embodiment, an execution subject (e.g., the server 105 shown in fig. 1) of the method for storing data may receive target data from a terminal. Here, the terminal may be a terminal used by a user. The target data may include various private data such as an application identification, an account number and password for logging into the application, or an image, video, etc. Here, the application identification may be a picture, a name, or the like of the application.
After receiving the target data, the execution main body divides the target data to obtain a plurality of data fragments. Here, the execution main body may divide the data into a preset number of data pieces according to the number of the data pieces when dividing the data. It may also be divided according to the size of the data slices, i.e. the size of each data slice is the same.
The execution body may encrypt each data fragment after obtaining each data fragment. Specifically, the executing entity may encrypt each data slice using an existing encryption algorithm. The execution body may then determine a memory address for each data slice. For example, the executing agent may randomly store the data shards into database shards of a distributed database. In some specific applications, in order to ensure the security of the encrypted data distribution, each data fragment may be stored in a different database fragment.
In some optional implementations of this embodiment, the execution body may further determine the storage address of the data slice by the following steps not shown in fig. 2: copying each encrypted data fragment; determining the corresponding relation between each encrypted data fragment and each database fragment in the distributed database; and taking the address of the database fragment corresponding to each data fragment as a storage address.
In this implementation, in order to ensure redundancy of the data fragments, the execution main body may copy each encrypted data fragment to obtain at least two identical data fragments. Then, the execution subject may determine a correspondence between each encrypted data fragment and each database fragment in the distributed database. Specifically, the executing body may select a database fragment for storing each encrypted data fragment from the database fragments on the premise that multiple parts of the same data fragment are not allocated to the same database fragment and that each data fragment corresponding to the target data is not allocated to the same database fragment. Finally, the executing agent may use the address of the database fragment storing each data fragment as the storage address of each data fragment.
And step 204, generating character strings corresponding to the data fragments according to the storage addresses of the data fragments.
In this embodiment, after obtaining the storage address of each data fragment, the execution main body may generate a character string corresponding to each data fragment. Specifically, the execution body may use the storage addresses of at least two data fragments as a character string corresponding to one of the data fragments.
The execution body may store the encrypted data fragment and the generated character string. Specifically, the execution agent may store the encrypted data fragments according to the storage address, and store the generated character string in the blockchain ledger.
It should be noted that all of the steps 201 to 205 may be executed by the same execution entity (i.e., the server 105 shown in fig. 1), or some of the steps may be executed by the server and some of the steps may be executed by the blockchain distributed storage server.
The method for storing data provided by the above embodiment of the application provides a safe and convenient login information storage method, which can facilitate a user to retrieve an account and a password of each application program.
In some optional implementations of this embodiment, the execution main body may further receive a request of adding, deleting, modifying, and checking the stored data from the user, so as to allow the user to flexibly process the stored data.
With continued reference to FIG. 3, a flow 300 of another embodiment of a method for storing data in accordance with the present application is illustrated. As shown in fig. 3, the method for storing data of the present embodiment may include the steps of:
In this embodiment, the execution main body may further receive verification information sent by the user through the terminal. And judging whether the verification information passes the verification, and if so, receiving the target data from the terminal. The verification information may include biometric information of the user, such as a fingerprint, voice, etc. The execution subject may determine whether the user currently using the terminal is a previously registered user through the above-described biometric information. If so, the target data may be received.
In some optional implementations of this embodiment, the target data includes an associated application identification, account information, and password information. For example, the target data may include account information aaaa of application a and password information 1111. It will be appreciated that the target data may include account information and password information for a plurality of applications. The application identifier may be a name, a picture or a sound of the application.
In some optional implementation manners of this embodiment, the verification information may include the first biometric information, a login account number of a preset application program, and password information.
In other optional implementations of this embodiment, the terminal may be unlocked by the second biometric information of the user. And the first biometric information is different from the second biometric information. For example, the first biometric information may be a fingerprint of an index finger and the second biometric information may be a fingerprint of a middle finger. Alternatively, the first biological information may be fingerprint information and the second biological information may be voice. The preset application may be an application that stores information of a user.
The execution subject may determine whether the check information passes through the following steps: and in response to determining that the login account number is matched with the password information and that the first biological characteristic information is pre-registered, determining that the verification information passes verification.
In this implementation, the execution subject may first determine whether the login account is matched with the password information. And if so, continuously judging whether the first biological characteristic information is pre-registered biological characteristic information. If yes, the verification information is confirmed to pass the verification.
In some alternative implementations of the present embodiment, the target data may include video and images. The execution body may also implement the above step 301 by the following steps not shown in fig. 3: determining the type and the data volume of target data and determining the network environment of a terminal; and receiving the target data in response to the fact that the type and the data volume of the target data and the network environment meet preset conditions.
In this implementation, the execution subject may also determine the type and amount of the target data. The types may include video, images, and the like. The data amount is used to indicate the size of the data. The execution agent may also determine the network environment of the terminal. The network environment may include a way to access the network, such as through a WiFi access network, or through a cellular network. If the type of the target data is video, the data volume is larger than a preset threshold value, and the network environment is to access the network through a cellular network, it can be determined that the preset condition is not met currently, and the target data is not received. And if the network environment is changed to access the network through WiFi, the target data can be received if the preset condition is currently met.
It should be noted that, when the preset condition is not satisfied, the execution subject may generate a hidden file of the target data, and set the hidden file, so that the target data is automatically uploaded when the preset condition is satisfied.
When the execution subject encrypts the data fragment, a key may be generated according to the verification information. Specifically, the executing entity may use the verification information as a key, or use a password in the verification information and the first biometric information as keys. The execution entity may then encrypt each data fragment using the key.
In some optional implementation manners of this embodiment, the execution main body may generate a character string corresponding to each data fragment through the following steps: determining a hash code of a storage address of each data fragment; and for each data fragment, determining a character string corresponding to the data fragment according to the hash code corresponding to the data fragment and the hash code corresponding to the next data fragment.
In this implementation, the execution main body may calculate the hash code of the storage address of each data slice, that is, calculate the hash code of the storage address of each data slice by using a hash algorithm. Then, the execution body may combine the hash code corresponding to each data slice with the hash code corresponding to the next data slice, and use the combined character string as the character string corresponding to the data slice.
In addition, in this implementation manner, the character string of the first encrypted data fragment may also be stored locally in the execution main body. In this way, the execution main body may determine the storage address of the first encrypted data fragment according to the character string locally stored by the execution main body, and may also determine the storage address of the second encrypted data fragment. And then, determining the storage address of a third encrypted data fragment according to the character string corresponding to the second encrypted data fragment. Thus, all encrypted data fragments are obtained. And decrypting each encrypted data fragment to obtain decrypted data fragments. And finally, combining all the decrypted data fragments to obtain target data.
In some optional implementations of this embodiment, after storing each data slice, the method may further include the following steps not shown in fig. 3: generating an identification list according to the application program identification; and in response to receiving an access request aiming at the application program identification in the identification list, outputting the associated account information and password information.
In this embodiment, the execution subject may further generate an identification list according to the application program identification included in the target data. For example, the executing subject may take a picture of the application as each identifier in the list of identifiers.
If the execution subject receives an access request aiming at the application program identification in the identification list, the account information and the password information related to the application program identification can be output for a user to view.
It can be understood that, before outputting the associated account information and password information, the execution main body may pop up a verification information input interface for the user to input verification information in the interface, and after the verification information input by the user passes verification, output the associated account information and password information.
In some optional implementations of this embodiment, the method may further include the following steps not shown in fig. 4: receiving a query request from a terminal; acquiring biological characteristic information; and outputting the target data in response to determining that the biological characteristic information passes the verification.
In this implementation, the execution main body may further receive an inquiry request sent by the terminal. Meanwhile, the execution subject may also acquire biometric information. The biometric information is different from the biometric information of the user for unlocking the terminal. And after the execution main body determines that the biological characteristic information passes the verification, the execution main body can output target data for a user to check through a terminal.
In some optional implementations of this embodiment, the method may further include the following steps not shown in fig. 3: in response to receiving an access request for an application program identifier in the identifier list, determining a login link of the application program; generating a login request aiming at a login page indicated by the login link according to the associated account information and the password information; and outputting the received login result aiming at the login request to the terminal.
In this implementation, if the execution subject receives an access request for an application identifier in the identifier list, the execution subject may also determine a login link of the accessed application. The login link may be a link to a login interface of the application. Then, the execution subject may generate a login request for the login page indicated by the login link according to the account information and the password information associated with the application program. Specifically, the execution subject may encapsulate the login link, the account information, and the password information to obtain the login request. Finally, the execution subject can send out the login request and receive the login result aiming at the login request. The login result may include login success and login failure. The execution agent may output the login result to the terminal.
With continued reference to fig. 4, a schematic diagram of an application scenario of the method for storing data according to the present application is shown. In the application scenario of fig. 4, a user first inputs an account and a password of an application a for storing information through the mobile phone 401, inputs fingerprint information, and logs in the application a. Then, the user inputs the account and the password of the mailbox application in the application program A. The server 402 of application a may first segment the information and then encrypt each resulting data slice. The encrypted data fragments are sent to the blockchain distributed storage server 403. The blockchain distributed storage server 403 calculates a character string corresponding to each encrypted data fragment, and stores each character string in the blockchain ledger 404. The user may also query the account number and password of each previously stored application through application a.
The method for storing data provided by the above embodiment of the application can store the data of the user by using the block chain technology, and meanwhile, the data is verified when the data is stored and read, so that the safety of data storage is improved.
