The following describes the technical solutions of the present invention and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a user information processing method according to an embodiment of the present invention. The embodiment of the invention provides a user information processing method aiming at the technical problems in the prior art, which comprises the following specific steps:
Optionally, the identity information of the transaction user includes: the identity card number and name of the transacting user.
As shown in fig. 3, the plurality of terminal devices are nodes in a blockchain network, and the blockchain network may specifically be a peer-to-peer network, and a transaction may be performed between any two nodes in the blockchain network. In this embodiment, the first transaction node may specifically be the terminal device 31 shown in fig. 3, and the second transaction node may specifically be the terminal device 32 shown in fig. 3.
When the terminal device 31 and the terminal device 32 perform a transaction based on the blockchain network, the terminal device 31 receives the segment information of the identity information of the transaction user corresponding to the terminal device 32 and the first verification information, which are sent by the terminal device 32 in the blockchain network. For example, the user corresponding to the terminal device 31 is denoted as a user a, the user corresponding to the terminal device 32 is denoted as a user B, the transaction user is specifically a user B, the segment information of the identity information of the transaction user is specifically segment information of the identity information of the user B, for example, the identity information of the user B is specifically an identity number and a name of the user B, and the segment information of the identity information of the user B specifically includes: the segment information of the id number of the user B is, for example, 230348204 × 00 × and the segment information of the name of the user B is, for example, li × four. In addition, the first verification information may specifically be a verification code corresponding to the identity information of the user B, for example, 75432.
Optionally, the receiving, by the first transaction node, the fragment information of the identity information of the transaction user corresponding to the second transaction node and the first verification information, where the fragment information is sent by the second transaction node in the blockchain network, includes: the first transaction node receives a broadcast message sent by a second transaction node in a blockchain network, wherein the broadcast message comprises identification information of the first transaction node, segment information of identity information of the transaction user and first verification information.
For example, when the terminal device 32 needs to perform a transaction with the terminal device 31, the terminal device 32 sends a broadcast message in the blockchain network, where the broadcast message is used to find the terminal device 31, and the broadcast message specifically includes: identification information of the terminal device 31 to be searched by the terminal device 32, segment information of the identification number of the user B, for example, 230348204 × 00 × the segment information of the name of the user B, for example, lie × four, and the authentication code, for example, 75432. In addition, the public key of the user B may be included in the broadcast message. Optionally, the terminal device 32 signs the broadcast message with a private key of the user B and sends the signed broadcast message to the blockchain network.
In this embodiment, the terminal device 31 locally stores the identity information of the known user in advance, and it can be understood that the terminal device 31 locally does not limit to storing the identity information of the known user, the terminal device 31 locally stores the identity information of a plurality of known users, and the identity information of the plurality of known users is complete identification numbers and names.
After receiving the broadcast message sent by the terminal device 32, the terminal device 31 first verifies whether the private key signature of the user B is correct, and if so, the terminal device 31 further determines, according to the identity information of the known user, second verification information corresponding to the identity information of the known user, taking the identity information of one of the known users as an example, optionally, the identity information of the known user includes: the identity card number and name of the known user. For example, the user's identification number is known as 23034820411100222X, and the user's name is known as LieXiao-Siu. The terminal device 31 determines second verification information corresponding to the identity information of the known user according to the identification card number and the name of the known user.
Optionally, the determining, by the first transaction node, second verification information corresponding to the identity information of the known user according to the locally pre-stored identity information of the known user includes: and the first transaction node calculates second verification information corresponding to the identity information of the known user by adopting a one-way function according to the locally pre-stored identity information of the known user.
For example, the terminal device 31 calculates, by using a one-way function, second authentication information corresponding to the identity information of the known user according to the identity number and the name of the known user, optionally, the second authentication information may also be an authentication code, where the authentication code is F (the identity number 23034820411100222X of the known user, the name of the known user is four), where F denotes the one-way function, and optionally, the one-way function is a hash function, that is, the identity number 23034820411100222X of the known user and the name of the known user are parameters of the one-way function. It will be appreciated that the authentication code can be calculated using the one-way function, the complete identification number and name of the known user, and the identification number and name of the known user cannot be calculated back from the authentication code.
In addition, in other embodiments, the verification code may also be calculated by:
the authentication code is F (identity number 23034820411100222X of the known user, the name of the known user, leeway, xxx), where xxx may be information that other identities of the known user, such as a passport number, a military functionality number, a geriatric number, etc., may uniquely identify the known user.
The terminal device 31 compares the authentication code, e.g. 75432, broadcast by the terminal device 32 in the blockchain network with the authentication code calculated by the terminal device 31 according to the one-way function.
If the authentication code, e.g. 75432, broadcast by the terminal device 32 in the blockchain network is identical to the authentication code calculated by the terminal device 31 according to the one-way function, the terminal device 32 further compares the identity information of the known user with the segment information of the identity information of the user B. That is, terminal device 32 compares 23034820411100222X and 230348204X 00X and compares lie four and lie small four.
It can be seen that the un-omitted part 230348204 × 00 × coincides with the corresponding part 23034820411100222X, and the un-omitted part "lie × four" coincides with the corresponding part "lie Xiao four", that is, 230348204 × 00 × and 23034820411100222X are matched, and "lie × four" and "lie Xiao four" are matched, at this time, the terminal device 31 determines that the user B corresponding to the terminal device 32 is a known user, that is, the terminal device 31 verifies the identity information of the user B, and the terminal device 31 can perform a secure transaction with the terminal device 32 after the verification is successful.
Optionally, after the terminal device 31 and the terminal device 32 complete the transaction, the transaction records in the blockchain specifically include: user a (identification number 110348204 × 00 × three name, verification code: 58763), user B (identification number 230348204 × 00 × four name, verification code: 75432), and 5-dollar transaction amount. That is, the transaction record in the blockchain does not record the complete identity information of the user, but records a segment of the identity information.
In the embodiment of the invention, the transaction node sends the fragment information of the user identity information in the blockchain network instead of the complete information, so that the complete identity information of the user is prevented from being exposed in the blockchain network, the privacy of the user is improved, in addition, the opposite node of the transaction node needs to verify the identity information of the user according to the fragment information of the user identity information, the transaction is carried out after the verification is passed, and the security of the transaction is improved.
Fig. 4 is a flowchart of a user information processing method according to another embodiment of the present invention. On the basis of the foregoing embodiment, the user information processing method provided in this embodiment specifically includes the following steps:
When the terminal device 32 needs to perform a transaction with the terminal device 31, the terminal device 32 sends a broadcast message in the blockchain network, where the broadcast message is used to find the terminal device 31, and the broadcast message specifically includes: identification information of the terminal device 31 that the terminal device 32 is to look for, and identification information of the terminal device 32. In addition, the public key of the user B may be included in the broadcast message. Optionally, the terminal device 32 signs the broadcast message with a private key of the user B and sends the signed broadcast message to the blockchain network.
After receiving the broadcast message sent by the terminal device 32, the terminal device 31 first verifies whether the private key signature of the user B is correct, and if so, the terminal device 31 further sends an identity information query request to the terminal device 32, where the identity information query request is used to query the identity information of the user B. For example, the identity information query request is used to query the identity card number and name of user B. After receiving the identity information query request sent by the terminal device 31, the terminal device 32 sends segment information of the identity card number of the user B and segment information of the name of the user B to the terminal device 31, where the segment information of the identity card number of the user B is, for example, 230348204 × 00 × and the segment information of the name of the user B is, for example, lie × four.
In other embodiments, the identity information query request may also be used to query other identifying information of user B, such as military functionality license number and name.
Alternatively, if the terminal device 31 locally stores the complete identification number and name of the known user, the terminal device 31 sends an identity information query request to the terminal device 32 to query the identification number and name of the user B. If the terminal device 31 locally stores the complete military officer license number and name of the known user, the terminal device 31 sends an identity information query request to the terminal device 32 to query the military officer license number and name of the user B, and so on.
In step 403, the first transaction node receives the segment information of the identity information of the transaction user corresponding to the second transaction node and the first verification information, which are sent by the second transaction node in the blockchain network.
And step 404, the first transaction node determines second verification information corresponding to the identity information of the known user according to the locally pre-stored identity information of the known user.
The specific implementation manner and principle of steps 403 to 407 are consistent with the above embodiments, and are not described herein again.
In the embodiment of the invention, the transaction node sends the fragment information of the user identity information in the blockchain network instead of the complete information, so that the complete identity information of the user is prevented from being exposed in the blockchain network, the privacy of the user is improved, in addition, the opposite node of the transaction node needs to verify the identity information of the user according to the fragment information of the user identity information, the transaction is carried out after the verification is passed, and the security of the transaction is improved.
