Example 1:

in order to improve the security of user registration and protect the privacy security of the user, the application provides a registration method, a registration device, registration equipment and a registration medium.

Fig. 1 is a schematic diagram of a registration process provided in some embodiments of the present application, where the registration process includes the following steps:

s101: receiving a registration instruction carrying target identification information of a user to be registered, and determining an encrypted first target hash value corresponding to the target identification information of the user to be registered according to the target identification information of the user to be registered and a correspondence between pre-stored identification information and the encrypted hash value, wherein the hash value is obtained by performing hash calculation based on identity information of the user, and the encrypted hash value is stored in a block chain.

The registration method provided by the embodiment of the application is applied to the electronic equipment, and the electronic equipment can be a PC (personal computer), a server or the like.

In order to improve the security of the identity information of the user, in the embodiment of the present application, the identity information of each user may be stored in a block chain in advance, where the identity information of the user may include a name, an identity card number, and the like of the user, and may also include a mobile phone number, and the registration method may be applied to various fields, such as a school, an enterprise, and the like. Wherein the identity information of each user stored in the blockchain is the correct and standard identity information of the user allowed to register.

In order to further improve the security of the identity information of the user, in this embodiment of the application, the identity information of the user may be subjected to hash calculation in advance for each user, a hash value corresponding to the identity information of the user is determined, then the hash value is encrypted to obtain an encrypted hash value, and the encrypted hash value is stored in the blockchain.

In this embodiment of the application, hash calculation may be performed on the identity information of the user based on a preset hash algorithm, where the preset hash algorithm may be a hash algorithm such as MD5, and specifically, the preset hash algorithm may be set according to a requirement.

The process of performing hash calculation on the identity information of the user and determining the hash value corresponding to the identity information of the user is the prior art, and is not described herein again.

On one hand, the blockchain has the advantages of being not falsifiable and traceability, so that the identity information of the user stored in the blockchain can be guaranteed not to be falsified, the addition, deletion and the like of the identity information of the user stored in the blockchain can be traced, and the safety problem of the identity information of the user can be favorably supervised; on the other hand, since the hash calculation is irreversible, that is, after the hash calculation is performed on the identity information of the user to determine the hash value corresponding to the identity information of the user, the hash value corresponding to the identity information of the user cannot be processed to obtain the identity information of the user, the security of the identity information of the user is further improved.

In order to implement secure registration, in the embodiment of the present application, an electronic device receives a registration instruction carrying identification information of a user to be registered, where the registration instruction carrying the identification information of the user to be registered and received by the electronic device is sent by a target device corresponding to the user to be registered, and the target device corresponding to the user to be registered is an electronic device used when the user is registered. The identification information may be information that can uniquely identify the user identity, such as a mobile phone number, a user name, an identity card number, and the like of the user.

In this embodiment of the application, when the user to be registered registers on the target device corresponding to the user to be registered, the registration instruction may be triggered by the application program to be registered installed on the target device, for example, the user to be registered may click a "registration" button in the application program to be registered on the target device to trigger the registration instruction, the user to be registered may also trigger the registration instruction by clicking a "acquire registration code" button in the application program to be registered on the target device to trigger the registration instruction, and specifically, how the target device triggers the registration instruction is not limited herein.

In order to determine which encrypted hash value of the encrypted hash values stored in the blockchain is the encrypted hash value corresponding to the user to be registered, in this embodiment of the application, a corresponding relationship between the identification information and the encrypted hash value is pre-stored in the electronic device, after the target identification information of the user to be registered is determined, the encrypted hash value corresponding to the target identification information is determined according to the identification information and the corresponding relationship between the pre-stored identification information and the encrypted hash value, and the determined encrypted hash value is used as the first encrypted target hash value.

S102: generating a target registration code; sending the target registration code to target equipment corresponding to the user to be registered; and decrypting the encrypted first target hash value to obtain the first target hash value.

In the embodiment of the application, in order to implement secure registration, after receiving a registration instruction carrying target identification information of a user to be registered, a target registration code can be generated and sent to a target device corresponding to the user to be registered, wherein the target registration code is a correct registration code for the user to refer to for completing the registration, the target registration code may be randomly generated, e.g., a fixed-length random number generated based on a random function, the random number being the target registration code, or a set number of digits are selected from 0 to 9, and the set number of digits are sorted according to a set order to obtain the target registration code, for example, if the number selected from 0 to 9 is 1, 2, 3, or 4, the generated target registration code may be 4321 or 2341, and so on. The target registration code can be sent to the target device by a short message or an email.

In order to facilitate subsequent authentication of the identity of the user to be registered and further determine whether the registration is successful, in the embodiment of the application, after the encrypted first target hash value is determined, the encryption algorithm for encrypting the first target hash value is stored locally, so that the encrypted first target hash value can be decrypted according to the encryption algorithm to obtain the first target hash value.

S103: receiving target registration identity information sent by the target equipment after the target registration code passes verification, and determining a second target hash value corresponding to the target registration identity information; and if the second target hash value is consistent with the first target hash value, determining that the registration is successful.

In this embodiment, after sending the generated target registration code to the target device corresponding to the user to be registered, the target device may receive the input registration verification code, verify whether the registration verification code is input correctly, if the registration verification code is input correctly, determine that the target registration code is verified to pass, and receive the target registration identity information sent by the target device after the target registration code is verified to pass, wherein an input field for inputting the verification code may be displayed to the user, and prompt information of the verification code to be input is displayed, the user inputs the registration verification code and the target registration identity information on a registration page of the registered application program, where what the input registration verification code is depends on a rule preset by the target device and the electronic device, such as if the preset rule is the last three digits of the input registration verification code, the target device, upon entering the enrollment authentication code, compares the enrollment authentication code with the last three digits of the target enrollment code to determine whether the entered enrollment authentication code is correct, and so on.

A common pre-set rule is that the registration verification code is consistent with the target registration code. If the registration verification code is consistent with the target registration code, the target registration code is determined to pass the verification, the target registration identity information is determined to be allowed to be sent to the electronic equipment, if the registration verification code is inconsistent with the target registration code, the target registration code is determined to fail the verification, and the target registration identity information is determined not to be sent to the electronic equipment. The target registration identity information may include a name, a mobile phone number, an identity card number, and other identity information, and content included in the target registration identity information is the same as identity information included in the identity information of the user to be registered, which is obtained by the electronic device, that is, when the identity information of the user to be registered, which is obtained by the electronic device, includes the name and the identity card number, the target registration identity information of the user to be registered also includes the name and the identity card number.

In order to complete the verification of the identity information of the user to be registered, in the embodiment of the present application, after receiving the target registration identity information of the user to be registered, the hash calculation is performed on the target registration identity information, a second target hash value corresponding to the target registration identity information is determined, the second target hash value is compared with the first target hash value, and whether the registration is successful is determined according to the comparison result.

Specifically, if the second target hash value is consistent with the first target hash value, it indicates that the target registration identity information of the user to be registered is correct, and it is determined that the registration is successful, and if the second target hash value is inconsistent with the first target hash value, it indicates that the target registration identity information of the user to be registered is incorrect, and it is determined that the registration is unsuccessful.

In the embodiment of the application, after the hash value obtained by hashing the identity information of the user is encrypted, the obtained encrypted hash value is stored in the block chain in advance, and due to the fact that the block chain is not capable of being tampered, the encrypted hash value can be guaranteed not to be tampered, the subsequent user registration safety is guaranteed, and due to the traceability of the block chain, the traceability of the user identity information is improved, namely, the newly added, deleted and obtained records of the encrypted user identity information in the block chain are traceable, so that whether a cracker cracks the encrypted identity information by using methods such as a reverse analysis technology and the like can be found quickly, and the registration safety is improved.

Example 2:

in order to determine the hash value corresponding to the identity information of each user, on the basis of the foregoing embodiment, in an embodiment of the present application, the process of determining the hash value corresponding to the identity information of each user includes:

In order to determine the hash value corresponding to the identity information of each user, in the embodiment of the present application, for each user, the identity information of the user is obtained, where the obtained identity information of the user is correct and standard identity information of the user, and then hash calculation is performed on the obtained identity information of the user to obtain the hash value corresponding to the identity information of the user.

In order to further improve the security of the identity information of the user, in this embodiment of the application, the hash value corresponding to the identity information of the user may be encrypted, specifically, the electronic device generates two public and private key pairs in advance, which are a first public and private key pair and a second public and private key pair respectively, where the first public and private key pair includes a first public key and a first private key, and the second public and private key pair includes a second public key and a second private key, and may perform signing processing on the hash value corresponding to the identity information of the user based on the first private key in the first public and private key pair to obtain a signed hash value corresponding to the user, and then encrypt the signed hash value based on the second public key in the second public and private key pair to obtain an encrypted hash value corresponding to the identity information of the user. Wherein, this first public private key pair and this second public private key pair can be the public private key pair of symmetry, also can be for asymmetric public private key pair, and is specific, can set up first public private key pair and second public private key pair according to the demand.

In this embodiment, the first private Key may be a signature private Key in a hardware digital certificate carrier (USB Key), where the USB Key is used to store a digital certificate representing a unique identity of a user and the signature private Key, and the signature private Key is generated within a high-security USB Key and cannot be exported outside the USB Key for life.

Specifically, the electronic device may have a USB Key inserted in advance, and add identity information to a plurality of users, where the identity information may include, for example, a name, a mobile phone number, an identity card number, a position, a department, and the like, and after obtaining the identity information of each user, identify information corresponding to the user is determined for the identity information of each user, where the mobile phone number in the identity information of the user may be determined as the identify information of the user, and a digital certificate and a signature private Key capable of representing a unique identity of the user are set for each user of the identify information, that is, a corresponding relationship between the identify information of the user and the signature private Key is pre-stored in the electronic device. After a registration instruction carrying target identification information of a user to be registered is received, a signature private key corresponding to the user to be registered is determined according to the identification information of the user to be registered, the signature private key corresponding to the user to be registered is determined as a first private key corresponding to the user to be registered, and the first private key is used for signing target identity information of the user to be registered.

The process of generating the first public-private key pair and the second public-private key pair is prior art and is not described herein again.

In order to obtain the first target hash value, on the basis of the foregoing embodiments, in an embodiment of the present application, the decrypting the encrypted first target hash value to obtain the first target hash value includes:

In the embodiment of the present application, since the encrypted first target hash value is obtained by encrypting the hash value corresponding to the identity information of the user to be registered, and the encrypted first target hash value is obtained by signing the hash value corresponding to the target identity information of the user to be registered based on the first private key in the first public-private key pair, so as to obtain the target signed hash value corresponding to the user to be registered, and then the target signed hash value is obtained by encrypting the target signed hash value based on the second public key in the second public-private key pair, in order to obtain the first target hash value according to the encrypted first target hash value, in the embodiment of the present application, the encrypted first target hash value is decrypted based on the second private key in the second public-private key pair, that is, the encrypted first target hash value is decrypted based on the second private key corresponding to the second public key obtained in advance, and obtaining a target signed hash value of the user to be registered, and then checking the target signed hash value based on a first public key in the first public and private key pair, namely checking the target signed hash value based on a first public key corresponding to a first private key obtained in advance to obtain a first target hash value corresponding to target identity information of the user to be registered.

In the embodiment of the present application, in order to ensure that the stored encrypted hash value stored in the blockchain has no error in the encryption process, and further ensure the accuracy of the encrypted hash value stored in the blockchain, in the embodiment of the present application, before the user registers, generally before the registered application is listed, the accuracy of the encrypted hash value stored in the blockchain may be verified, and specifically, because the signed hash value corresponding to the identity information of the user is signed based on the first private key when the encrypted hash value is obtained, the signed hash value corresponding to the user is obtained, the signed hash value may be referred to as a first signed hash value, and the first signed hash value is encrypted based on the second public key to obtain an encrypted hash value corresponding to the identity information of the user, and the obtained signed hash value corresponding to the user is referred to as a first signed hash value.

When the encrypted hash value is verified, the encrypted hash value is decrypted based on a second private key to obtain a signed hash value corresponding to the user, the obtained signed hash value corresponding to the user is called a second signed hash value, the second signed hash value is verified based on the first public key to obtain a hash value corresponding to the identity information of the user, and the obtained hash value corresponding to the identity information of the user is called the second hash value. In order to verify the accuracy of the encrypted hash value stored in the blockchain, in the embodiment of the present application, it is determined whether the first signed hash value and the second signed hash value are changed or not, if so, it is determined that the verification fails, if not, it is determined that the first hash value and the second hash value are changed or not, if so, it is determined that the verification fails, and if not, it is determined that the verification succeeds.

Specifically, the electronic device pre-stores a first hash value and a first signed hash value corresponding to each user, and in order to improve security, the first hash value and the first signed hash value corresponding to each user may also be stored in the block chain.

Specifically, the verification interval duration may be preset, so that the electronic device verifies the accuracy of the encrypted hash value stored in the block chain once every other verification interval duration, or the electronic device may verify the accuracy of the encrypted hash value stored in the block chain once after receiving the verification instruction.

Example 3:

in order to improve the security of registration, on the basis of the foregoing embodiments, in an embodiment of the present application, after the generating the target registration code, the method further includes:

In order to improve the security of registration, in this embodiment of the present application, an encrypted registration code obtained by encrypting the registration code may also be stored in the blockchain. Specifically, the target registration code is signed based on a second private key obtained in advance to obtain a signed target registration code, then the signed target registration code is encrypted based on a first public key to obtain an encrypted target registration code, then the encrypted target registration code is subjected to hash calculation to obtain a hash value corresponding to the encrypted target registration code, and the hash value corresponding to the encrypted target registration code is stored in a block chain.

On one hand, as the blockchain has non-falsification and traceability, the hash value corresponding to the encrypted registration code stored in the blockchain can be guaranteed not to be falsified, and the addition, deletion and the like of the hash value corresponding to the encrypted registration code stored in the blockchain can be traced, which is beneficial to supervising the safety problem; on the other hand, since the hash calculation is irreversible, that is, after the hash calculation is performed on the encrypted target registration code to obtain the hash value corresponding to the encrypted target registration code, the target registration code cannot be obtained by processing according to the hash value corresponding to the encrypted target registration code, and therefore, the registration security is further improved.

Example 4:

In the embodiment of the application, after the target device corresponding to the user to be registered receives the target registration code sent by the electronic device, verification can be performed based on the target registration code, that is, the user needs to input the registration verification code based on the target device. Therefore, in order to implement verification of the target registration code, in the embodiment of the application, when receiving target registration identity information sent after the target device passes the verification of the target registration code, the electronic device may also receive a registration verification code sent after the target device passes the verification of the target registration code.

Since the hash value corresponding to the encrypted target registration code is stored in the blockchain, and since the hash calculation is irreversible, that is, the target registration code cannot be obtained based on the hash value corresponding to the encrypted target registration code, in the embodiment of the present application, in order to perform registration code verification, for each user, after receiving the registration verification code sent by the target equipment corresponding to the user, signing the registration verification code based on the second private key to obtain a signed registration verification code, and then encrypting the signed registration verification code based on the first public key to obtain an encrypted registration verification code, performing hash calculation on the encrypted registration verification code to obtain a hash value corresponding to the encrypted registration verification code, and finally comparing the hash value corresponding to the encrypted registration verification code with the hash value corresponding to the encrypted target registration code of the user stored in the block chain.

Specifically, in order to determine which encrypted target registration code corresponds to the hash value corresponding to the encrypted target registration code corresponding to the user to be registered among the hash values corresponding to all encrypted target registration codes stored in the blockchain, a correspondence between the identification information of the user and the hash value of the encrypted target registration code is stored in the electronic device in advance, and the hash value of the encrypted target registration code corresponding to the user to be registered is determined based on the identification information of the user to be registered. If the hash value corresponding to the encrypted registration verification code is consistent with the hash value corresponding to the target registration code stored in the blockchain, whether the registration verification code is still valid or not can be considered, specifically, the registration duration corresponding to the target login registration code can be determined according to the time of sending the target registration code and the time of receiving the registration verification code. If the registration time length does not exceed the preset time length threshold value, determining that the registration verification code is valid, and subsequently judging whether the second target hash value is consistent with the first target hash value or not and judging whether the registration is successful or not.

If the hash value corresponding to the encrypted registration verification code is not consistent with the hash value corresponding to the encrypted target registration code of the user stored in the blockchain, or the hash value corresponding to the encrypted registration verification code is consistent with the hash value corresponding to the encrypted target registration code of the user stored in the blockchain, but the registration verification code fails, it is determined that the registration fails. If the registration time length corresponding to the target login registration code is determined according to the time for sending the target registration code and the time for receiving the registration verification code, and if the registration time length exceeds a preset time length threshold value, the registration verification code is determined to be invalid. The preset duration threshold may be 5 minutes, 30 minutes, 1 hour, or the like, and specifically, the preset duration threshold may be set according to a requirement.

Specifically, in the embodiment of the present application, in the process of generating the target registration code according to the target identity information of the user to be registered and the timestamp corresponding to the current time, all the characters, numbers, or characters included in the target identity information of the user to be registered and the timestamp corresponding to the current time may be arranged in a random arrangement manner, and the arranged result is determined as the generated target registration code.

In the embodiment of the present application, a part of the texts, numbers or characters may be screened out from the target identity information of the user to be registered and all the texts, numbers or characters contained in the timestamp corresponding to the current time, and the screened texts, numbers or characters may be arranged in a random arrangement manner to generate the target registration code. Specifically, several words or numbers or characters are screened from the target identity information of the user, and the several words or numbers or characters screened from the timestamp corresponding to the current time may be preset, which is not limited herein.
