Example 1:

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

Fig. 1 is a schematic diagram of a registration process according to 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 the corresponding relation between the pre-stored identification information and the encrypted hash value, wherein the hash value is obtained by carrying out hash calculation based on identity information of the user, and the encrypted hash value is stored in a blockchain.

The registration method provided by the embodiment of the application is applied to the electronic equipment, and the electronic equipment can be a PC or a server and 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 the blockchain 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 be registered.

In order to further improve the security of the identity information of the user, in the embodiment of the application, hash calculation can be performed on the identity information of each user in advance, a hash value corresponding to the identity information of the user is determined, then the hash value is encrypted, an encrypted hash value is obtained, and the encrypted hash value is stored in a blockchain.

In the embodiment of the application, the hash calculation can be performed on the identity information of the user based on a preset hash algorithm, wherein the preset hash algorithm can be a hash algorithm such as MD5, and the preset hash algorithm can be specifically set according to requirements.

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

On the one hand, the blockchain has non-falsification and traceability, so that the identity information of the user stored in the blockchain can be ensured not to be falsified, and the new addition, deletion and the like of the identity information of the user stored in the blockchain can be traced, thereby being beneficial to supervising the safety problem of the identity information of the user; 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, so that the security of the identity information of the user is further improved.

In order to achieve 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 identification information of the user to be registered 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 that electronic device used when the user is registered. The identification information may be information that can uniquely identify the identity of the user, such as a mobile phone number, a user name, an identity card number, and the like of the user.

In the embodiment of the present application, when a user to be registered registers on a target device corresponding to the user to be registered, a registration instruction may be triggered by an 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, and 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, which is not limited herein.

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

S102: generating a target registration code; and the target registration code is sent 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 present application, in order to implement secure registration, after receiving a registration instruction carrying target identification information of a user to be registered, an electronic device may generate a target registration code and send the target registration code to a target device corresponding to the user to be registered, where the target registration code is a registration code that is correct and is used for a user to refer to and complete registration, the target registration code may be randomly generated, for example, a random number with a fixed length generated based on a random function is used as the target registration code, or a set number of digits is screened out from 0-9, and the set number of digits is sequenced according to a set order to obtain the target registration code, for example, digits screened out from 0-9 are 1,2, 3,4, and the generated target registration code may be 4321 or 2341. The target registration code can be sent to the target device by means of short messages or mails.

In order to facilitate the subsequent verification of the identity of the user to be registered and further determine whether the registration is successful, in the embodiment of the present application, after the encrypted first target hash value is determined, an 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 is verified to pass, 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 the embodiment of the application, after the generated target registration code is sent to the target device corresponding to the user to be registered, the target device can receive the input registration verification code and verify whether the registration verification code is input correctly, if the registration verification code is input correctly, the target registration verification code is determined to pass, and target registration identity information sent by the target device after the target registration code is verified to pass is received, wherein an input column of the input verification code can be displayed for the user, 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 a registered application program, wherein the input registration verification code depends on rules preset by the target device and the electronic device, and if the preset rules are the last three digits of the input registration verification code, the target device compares the registration verification code with the last three digits of the target registration code after the registration verification code is input, and determines whether the input registration verification code is correct or not, and the like.

A general preset 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, determining that the target registration code is verified, determining that the target registration identity information is allowed to be sent to the electronic equipment, if the registration verification code is inconsistent with the target registration code, determining that the target registration code is failed to be verified, and determining that the target registration identity information is not allowed to be sent to the electronic equipment. The target registration identity information may include name, mobile phone number, identity card number, etc., and the content included in the target registration identity information is the same as the identity information included in the identity information of the user to be registered obtained by the electronic device, that is, when the electronic device obtains that the identity information of the user to be registered includes name and identity card number, the target registration identity information of the user to be registered also includes name and identity card number.

Since the identity information of the user stored in the blockchain is already subjected to hash calculation, and since the hash calculation has irreversibility, that is, the first target hash value cannot be converted into the identity information of the user to be registered, in order to complete verification of the identity information of the user to be registered, in the embodiment of the application, after receiving the target registration identity information of the user to be registered, 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 registration is successful is determined according to a comparison result.

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

In the embodiment of the application, after the hash value obtained after the hash processing is carried out on the identity information of the user is encrypted, the obtained encrypted hash value is stored in the blockchain in advance, the encrypted hash value can be ensured not to be tampered due to the non-tamper property of the blockchain, the security of the subsequent user registration is ensured, and the traceability of the user identity information is also improved due to the traceability of the blockchain, namely, the new addition, deletion and acquisition record of the encrypted user identity information in the blockchain are traceable, so that whether a cracker uses a reverse analysis technology and other methods to crack the encrypted identity information can be quickly found, and the security of the registration is improved.

Example 2:

in order to determine the hash value corresponding to the identity information of each user, in the 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 a hash value corresponding to the identity information of each user, in the embodiment of the present application, the identity information of each user is obtained, wherein 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 the 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-private key pairs in advance, which are a first public-private key pair and a second public-private key pair, where the first public-private key pair includes a first public key and a first private key, and the second public-private key pair includes a second public key and a second private key, and may first sign the hash value corresponding to the identity information of the user based on the first private key in the first public-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-private key pair to obtain an encrypted hash value corresponding to the identity information of the user. The first public-private key pair and the second public-private key pair can be symmetric public-private key pairs or asymmetric public-private key pairs, and specifically, the first public-private key pair and the second public-private key pair can be set according to requirements.

In the embodiment of the present application, 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 is generated in the USB Key with high security, and cannot be derived to the outside of the USB Key.

Specifically, the electronic device may insert a USB Key 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 job position, a department, etc., and after obtaining the identity information of each user, determine identification information corresponding to the user with respect to the identity information of each user, where the mobile phone number in the identity information of the user may be determined as identification information of the user, and set, with respect to each user of the identification information, a digital certificate and a signature private Key that can represent a unique identity of the user for each user, that is, a correspondence between the identification 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, determining a signature private key corresponding to the user to be registered according to the identification information of the user to be registered, determining the signature private key corresponding to the user to be registered as a first private key corresponding to the user to be registered, and signing the target identification information of the user to be registered by using the first private key.

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

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

In the embodiment of the application, since the encrypted first target hash value is obtained after 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 of the first public key pair, the target signed hash value corresponding to the user to be registered is obtained, and then the target signed hash value is obtained after encrypting the target signed hash value based on the second public key of the second public key pair, in order to obtain the first target hash value according to the encrypted first target hash value, in the embodiment of the application, the encrypted first target hash value is firstly decrypted based on the second private key of the second public key pair, that is, the encrypted first target hash value is decrypted based on the second private key corresponding to the second public key, and then the target signed value corresponding to the first public key of the first public key pair is obtained, and the target signed value is obtained based on the first private key corresponding to the first private key of the first public key pair.

In the embodiment of the 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 application, the accuracy of the encrypted hash value stored in the blockchain can be verified a priori before the user registers, generally before the registered application program is marketed, specifically, when the encrypted hash value is obtained, the hash value corresponding to the identity information of the user is signed based on the first private key to obtain the signed hash value corresponding to the user, the signed hash value can be called as a first signed hash value, the first signed hash value is encrypted based on the second public key to obtain the encrypted hash value corresponding to the identity information of the user, and the signed hash value corresponding to the user is called as a first signed hash value.

When the encrypted hash value is verified, firstly, 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 checked based on a 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 a 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, if so, it is determined that the verification is failed, if not, it is determined whether the first hash value and the second hash value are changed, if so, it is determined that the verification is failed, and if not, it is determined that the verification is successful.

Specifically, the electronic device stores the first hash value and the first signed hash value corresponding to each user in advance, 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 blockchain.

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

Example 3:

In order to improve the security of registration, in the embodiments of the present application, after generating the target registration code, the method further includes:

In order to improve the security of registration, after the electronic device generates a target registration code, the target registration code is sent to target equipment corresponding to a user to be registered, the target registration code is encrypted, the encrypted target registration code is stored in the local area of the electronic device, and after the target registration code is verified, target registration identity information is sent to the electronic device by the target equipment corresponding to the user to be registered, however, under the related technology, due to the fact that a cracker can crack the registration code of software by using methods such as a reverse analysis technology and an algorithm for extracting the registration code, the security of a conventional registration code system is low. In order to improve the security of registration, in the embodiment of the present application, an encrypted registration code obtained by encrypting the registration code may also be stored in a blockchain. Specifically, signing is performed on the target registration code based on a second private key obtained in advance to obtain a signed target registration code, then encryption is performed on the signed target registration code based on a first public key to obtain an encrypted target registration code, hash calculation is performed on the encrypted target registration code 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 blockchain.

On the one hand, the blockchain has non-falsifiability and traceability, so that the hash value corresponding to the encrypted registration code stored in the blockchain can be ensured not to be falsified, and the new addition, the deletion and the like of the hash value corresponding to the encrypted registration code stored in the blockchain can be traced, thereby being beneficial to supervising the security 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, the target registration code cannot be obtained by processing according to the hash value corresponding to the encrypted target registration code after the hash value corresponding to the encrypted target registration code is obtained, and thus the security of registration is further improved.

Example 4:

Signing the registration verification code based on the second private key to obtain a signed registration verification code; encrypting the signed registration verification code based on the first public key to obtain an encrypted registration verification code; carrying out hash calculation on the encrypted target registration code to obtain a hash value corresponding to the encrypted target registration code;

Determining whether the hash value corresponding to the encrypted registration verification code is consistent with the hash value corresponding to the encrypted target registration code corresponding to the user to be registered, which is stored in the blockchain, wherein the hash value corresponding to the encrypted target registration code corresponding to the user to be registered is determined according to the identification information corresponding to the user to be registered and the corresponding relation between the pre-stored identification information and the hash value corresponding to the encrypted target registration code; if the target hash value is consistent with the first target hash value, determining the registration duration corresponding to the registration verification code according to the time for sending the target registration code and the time for receiving the registration verification code, and if the registration duration does not exceed a preset duration threshold value, performing subsequent operations if the second target hash value is consistent with the first target hash value, and determining that the registration is successful.

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 realize verification of the target registration code, in the embodiment of the application, when receiving the target registration identity information sent after the target registration code is verified by the target device, the electronic device can also receive the registration verification code sent after the target registration code is verified by the target device.

Because the hash value corresponding to the encrypted target registration code is stored in the blockchain, and because the hash calculation has irreversibility, that is, the target registration code cannot be obtained based on the hash value corresponding to the encrypted target registration code, in order to perform registration code verification, in the embodiment of the application, after receiving the registration verification code sent by the target device corresponding to the user, for each user, the registration verification code is signed based on the second private key to obtain a signed registration verification code, then the signed registration verification code is encrypted based on the first public key to obtain the encrypted registration verification code, the hash calculation is performed on the encrypted registration verification code to obtain the hash value corresponding to the encrypted registration verification code, and finally the hash value corresponding to the encrypted registration verification code is compared with the hash value corresponding to the encrypted target registration code of the user stored in the blockchain.

Specifically, in order to determine which hash value corresponding to the encrypted target registration code among the hash values corresponding to all the encrypted target registration codes stored in the blockchain is the hash value corresponding to the encrypted target registration code corresponding to the user to be registered, the corresponding relationship 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 effective 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 duration does not exceed the preset duration threshold, determining that the registration verification code is valid, and then performing subsequent judgment on whether the second target hash value is consistent with the first target hash value or not, and whether registration is successful or not.

If the hash value corresponding to the encrypted registration verification code is inconsistent 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, determining that registration fails. And if the registration duration exceeds a preset duration threshold, determining that the registration verification code is invalid. The preset duration threshold may be 5 minutes, 30 minutes, 1 hour, etc., and specifically, the preset duration threshold may be set according to requirements.

Example 5:

in order to generate the target registration code, on the basis of the above embodiments, in an embodiment of the present application, the generating the target registration code includes:

In the embodiment of the application, the electronic equipment can randomly generate the registration code, and can also generate the target registration code according to the target identity information of the user to be registered and the timestamp corresponding to the current time, specifically, in order to determine the target identity information of the user to be registered from the identity information of each user, in the embodiment of the application, the correspondence between the identification information and the identity information of the user is pre-stored in the electronic equipment, and after receiving a registration instruction carrying the target identification information of the user to be registered, the electronic equipment acquires the target identification information of the user to be registered carried in the registration instruction, and determines the target identity information corresponding to the target identification information of the user to be registered according to the target identification information and the pre-stored correspondence between the identification information and the identity information of the user.

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 or 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.

Because all characters or numbers or characters contained in the target identity information of the user to be registered and the timestamp corresponding to the current time are arranged in a random arrangement mode, the arranged result is determined to be the generated target registration code, the length of the target registration code is possibly too long, and the target registration code verification by the subsequent user is inconvenient. Specifically, several letters or numbers or characters are screened from the target identity information of the user, and several letters or numbers or characters are screened from the timestamp corresponding to the current time and can be preset, which is not limited herein.

For example, if the current timestamp is 202108301500, three digits are randomly extracted from the current timestamp "202108301500" and are respectively 8, 3 and 0, then three digits are randomly extracted from the phone number "11111100000" in the user identity information and are respectively 1,1 and 0, and the six digits are randomly arranged to obtain the target registration codes, which can be 130801, 110803 and the like.
