While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flowchart of an identity recognition method based on a block chain according to an embodiment of the present invention. As shown in fig. 1, the identity recognition method based on the block chain specifically includes the following steps:
step S110, receiving user identity information sent by the terminal user.
The identity information of the user may be information of various certificates which can indicate the identity of the user, such as an identity card number, account number information, passport card number, and the like. When the user draws a lottery, the user can send identity information which can indicate the identity of the user to the system, and the system receives the user identity information sent by the terminal user. The system can receive the identity information after the user sends the identity information, and can also automatically extract the user identity information input by the user when the user registers an account.
And step S120, generating ciphertext information corresponding to the user identity information according to a preset ciphertext processing rule.
In order to prevent the identity information of the user from being seen by other users, the identity information can be processed according to a preset ciphertext processing rule in the step, so that ciphertext information corresponding to the identity information of the user is generated. Specifically, plaintext information corresponding to the identity information may be obtained, and then an encryption algorithm is used to perform an encryption operation on the plaintext information to obtain ciphertext information corresponding to the identity information. Wherein, the encryption algorithm includes but is not limited to at least one of the following: hash operation, DES encryption algorithm, AES encryption algorithm, etc. In addition to generating the ciphertext information corresponding to the user identity information in the above manner, the ciphertext information corresponding to the user identity information may be generated in other manners.
Step S130, binding the ciphertext information corresponding to the user identity information and the user account of the terminal user into a related data record.
In order to identify the identity information corresponding to each account, the ciphertext information corresponding to the user identity information and the user account of the terminal user may be bound into one associated data record, so as to implement the one-to-one correspondence relationship between the user account and the ciphertext information corresponding to the user identity information.
Step S140, storing the associated data records into the corresponding block chain nodes; wherein the associated data record is used to identify the identity of the end user.
Specifically, the identity of the terminal user can be identified by identifying ciphertext information corresponding to the user identity information in the associated data record and according to the identity information of the user. The associated data records are stored on the corresponding block chain nodes, so that the associated data on the block chain can be seen by all users, but otherwise, the identity information of the users cannot be obtained according to the associated data, so that various activities can be performed more fairly and safely, and if the users are the users corresponding to the winning accounts or not during the prize exchanging process, the user can be judged according to the identity information of the users.
According to the identity recognition method based on the block chain, ciphertext information corresponding to the user identity information is generated by receiving the user identity information sent by a terminal user according to a preset ciphertext processing rule, so that the ciphertext information corresponding to the user identity information and a user account of the terminal user are bound into a related data record, and the related data record is stored in a corresponding block chain node; wherein the associated data record is used to identify the identity of the end user. According to the method, the identity information corresponding to the user account can not be seen by other users, so that the privacy of the user corresponding to each account is protected, fair and fair lottery activities can be performed, the account information of the matched user can be acquired according to the identity information of the user, and whether the user who is cashed before is the user corresponding to the winning account can be judged according to the acquired identity information of the user in the lottery activities.
Fig. 2 shows a flowchart of an identity recognition method based on a block chain according to an embodiment of the present invention. As shown in fig. 2, the identity recognition method based on the block chain specifically includes the following steps:
step S210, receiving user identity information sent by the terminal user.
The specific steps can be referred to the content in step S110.
Step S220, generating ciphertext information corresponding to the user identity information according to a preset ciphertext processing rule.
Specifically, plaintext information corresponding to the above-described identity information is first determined. Specifically, key information corresponding to the user account of the terminal user may be determined, and then plaintext information corresponding to the user identity information may be determined according to the key information. The key information may be public key information. In particular, to implement a decentralized trust mechanism, each network node in the blockchain has a corresponding private or public key, where the public key is public and the private key is secret.
And then, carrying out encryption operation on the plaintext information through an encryption algorithm to obtain ciphertext information corresponding to the user identity information. The preset encryption algorithm may be: and (6) carrying out hash operation. The hash operation may include: the MD4 algorithm, the MD5 algorithm, the secure hash algorithm (SHA-1), etc. The hash operation may map an arbitrary length binary value to a shorter fixed length binary value, this small binary value being referred to as the hash value. Hash values are a unique and extremely compact representation of a piece of data as a value. If a piece of plaintext is hashed and even if only one letter of the piece is altered, the subsequent hash will produce a different value. The hash operation has irreversibility and no conflict, wherein the irreversibility means that when the hash value of x is known, x cannot be calculated according to the hash value; the non-collision means that when x is known, one y value cannot be obtained to make the hash values of x and y the same. According to the irreversibility of the hash operation, when the ciphertext information on the block chain is obtained, the identity information of the user cannot be reversely deduced according to the ciphertext information, so that the fairness and the reliability of the transaction can be ensured through the block chain with the public information, and the personal privacy of the user can be prevented from being leaked.
Step S230, binding the ciphertext information corresponding to the user identity information and the user account of the terminal user into a related data record.
Specifically, a comparison table of the ciphertext information and the user account of the terminal user may be preset, and after the ciphertext information corresponding to the user identity information is generated, the ciphertext information corresponding to the user identity information and the user account of the terminal user are stored in the comparison table correspondingly, so that the ciphertext information corresponding to the user identity information and the user account of the terminal user are bound into a related data record. Besides the above method, the ciphertext information corresponding to the user identity information and the user account of the terminal user may be bound into a related data record in other ways. By implementing the steps, the one-to-one correspondence relationship between the user account and the ciphertext information corresponding to the user identity information is realized.
Step S240, storing the associated data record into the corresponding block chain node; wherein the associated data record is used to identify the identity of the end user.
By identifying the ciphertext information corresponding to the user identity information in the associated data and according to the acquired identity information of the cashing user, the identity of the terminal user can be identified to judge whether the cashing user is a winning user. The cashing mainly refers to the cashing of resources, and the resources comprise various physical resources or virtual resources such as prizes, red parcels and the like. The association data records are stored in the corresponding block chain nodes, so that the association data on the block chain can be seen by all users, but the identity information of the users cannot be obtained according to the association data, so that various lottery activities can be performed more fairly and safely, and whether the users are the users corresponding to winning accounts or not can be judged according to the identity information of the users during redemption.
Step S250, receiving a resource allocation request sent by a terminal user, and determining whether to allocate corresponding resources for a user account included in an associated data record according to the resource allocation request and a preset resource allocation algorithm; and if so, determining the associated data record as the resource configuration data record.
Specifically, after various resource configuration requests such as a lottery request and the like sent by a terminal user are received, a user account included in the resource configuration request is obtained, whether resources are configured for the user account is determined according to a preset resource configuration algorithm, if yes, a relevant data record including the user account is determined, and the user account included in the relevant data record is determined to win a prize. The resource allocation request mainly refers to a lottery drawing request, and can also include a drawing request, a shaking number request and/or a red packet robbing request.
Step S260, if yes, determining the associated data record as the resource configuration data record.
And if the user account contained in the associated data record is determined to be a prize, determining the associated record as the resource configuration data record.
Step S270, acquiring the redemption identity information of the redemption user.
Specifically, a scanning result obtained by scanning the identity provided by the redemption user may be obtained, and the redemption identity information of the redemption user may be determined according to the scanning result. The identity mark can be an identity card or other certificates which can show the identity of the redemption user, and the identity card can be scanned and the scanning result is identified, so that the redemption identity information of the redemption user is determined according to the scanning result. In addition to scanning the identity card to obtain the identity information of the redemption user, the staff can manually input the card number of the identity card of the redemption user, or take a picture of the identity card, so that the identity card number in the picture is automatically identified according to the picture, and the like, to determine the redemption identity information of the redemption user.
Step S280, a ciphertext message corresponding to the redemption identity message is generated according to a preset ciphertext processing rule.
The preset ciphertext processing rule may be the same as the preset ciphertext processing rule in step S220, so that when the redemption identity information is consistent with the identity information corresponding to the winning account, ciphertext information matched with the ciphertext information in the resource configuration data record may be generated according to the step.
Step S290, it is determined whether the ciphertext information corresponding to the redemption identity information matches the ciphertext information corresponding to the user identity information included in the resource configuration data record.
And step S2010, identifying the identity of the redemption user according to the judgment result.
If it is determined in step S290 that the ciphertext information corresponding to the redemption identity information matches the ciphertext information corresponding to the user identity information contained in the resource configuration data record, it may be determined that the identity information of the redemption user is consistent with the user identity information corresponding to the ciphertext information in the resource configuration data record, and thus the redemption user is determined to be a winning user, otherwise, the redemption user is not a winning user.
According to the identity recognition method based on the block chain provided by the embodiment, the user identity information sent by the terminal user is received, and the ciphertext information corresponding to the user identity information is generated according to the preset ciphertext processing rule, so that the ciphertext information corresponding to the user identity information and the user account number of the terminal user are bound into a related data record, and the related data record is stored in the corresponding block chain node; and after acquiring the redemption identity information of the redemption user, judging whether the ciphertext information corresponding to the redemption identity information is matched with the ciphertext information corresponding to the user identity information contained in the resource configuration data record, so as to identify the identity of the redemption user according to a judgment result. According to the method, the fairness and the reliability of the activities can be ensured through the block chain with the information disclosed, the personal privacy of the user can be prevented from being revealed, and whether the user is the user corresponding to the winning account can be judged according to the identity information of the cashing user, so that the cashing accuracy is ensured, and the rights and interests of the cashing user are guaranteed.
