The invention provides a block chain real-name authentication method, which aims to solve the technical problems in the prior art.
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 block chain real-name authentication method according to an embodiment of the present invention. The embodiment of the invention provides a block chain real-name authentication method aiming at the technical problems in the prior art, and the method comprises the following specific steps:
In this embodiment, the blockchain network includes a blockchain participating node and a mining node, where the blockchain participating node may be specifically the terminal device 12 shown in fig. 1, and the mining node may be specifically the server 13 shown in fig. 1. In addition, the blockchain network may further include a blockchain initiating node, where the blockchain initiating node issues a problem a in the blockchain network in a broadcast manner, and for blockchain participating nodes applying for real-name system verification, such as the terminal device 12, and mining nodes that want to obtain the accounting right, such as the server 13, the problem a broadcast by the blockchain initiating node in the blockchain network at the current time needs to be recorded in real time.
In this embodiment, when the terminal device 12 first accesses the blockchain network, the terminal device 12 needs to perform real-name authentication, specifically, the terminal device 12 broadcasts a first registration message in the blockchain network, where the first registration message includes a first timestamp local to the terminal device 12, and the first timestamp is denoted as T1, and in addition, the first registration message may further include: identification information, name, identification number, public key of the user of the terminal device 12. Specifically, the terminal device 12 may employ its own private key to sign the identification information, name, identification number, public key, and the first timestamp of the user, and then broadcast the signature to the blockchain network.
When the server 13 receives the first registration message, a second timestamp local to the server 13 when the server 13 receives the first registration message is recorded, and the second timestamp is denoted as T2, and further, the server 13 compares the first timestamp T1 with the second timestamp T2 in the first registration message.
When the time difference between the first time stamp T1 and the second time stamp T2 is less than or equal to the first preset time difference threshold, the server 13 may further receive a second registration message broadcast by the terminal device 12 in the blockchain network, where the second registration message includes a third time stamp T3 local to the terminal device 12, video information of the user, a name and an identification number, and the second registration message may further include: user identification information, ID card head portrait information and public key. Specifically, the terminal device 12 may use its own private key to sign the identification information, name, identification number, identification card icon information, public key, and the third timestamp T3 local to the terminal device 12 of the user, and then broadcast the signed information and video information of the user to the blockchain network.
Specifically, the terminal device 12 is provided with a shooting device, and a user can record video information through the terminal device 12, where the video information is specifically video information of the user, and specifically, the user can shoot a face of the user and an identity document of the user through the terminal device 12, where the identity document may be specifically a document such as an identity card and a passport of the user, so that the video information includes image information of the identity card or the passport of the user, and the image information of the identity card or the passport of the user included in the video information is recorded as first image information. Taking the id card of the user as an example, the first image information may include a name, an id number, and head portrait information of the user on the id card of the user. In addition, the video information may also include time information when the video information was recorded. The time information during the recording of the video information comprises the following possible implementation modes:
one possible implementation is: the video information comprises audio information of the user, and the audio information comprises time information when the video information is recorded. For example, when the user records the video information through the terminal device 12, the user may dictate the current recording time, for example, the video information recorded in minutes and seconds on the day of the month, that is, the video information further includes the audio information of the user, which is specifically the voice information that the user dictates the recording time, and here, the current recording time dictated by the user is taken as the time information when the video information is recorded.
Another possible implementation is: the video information comprises second image information of the timer, and the second image information comprises time information when the video information is recorded. For example, when the user records the video information through the terminal device 12, the terminal device 12 may be aligned with and photograph a timer, which may be specifically a clock, which may be specifically a time electronic clock that displays the time of the month and the day. Here, the image information of the timer captured by the terminal device 12 is referred to as second image information, that is, the video information recorded by the terminal device 12 includes the second image information, and the second image information includes time information of the video information recorded displayed by the timer.
In addition, the terminal device 12 may also locally record a problem a broadcast by the blockchain initiating node in the blockchain network, and the video information may further include: the user's explanation and answer to the question a.
In addition, if the time difference between the first time stamp and the second time stamp is greater than a first preset time difference threshold, the mining node determines to abandon writing the first registration message into a blockchain ledger.
For example, when the time difference between the first time stamp T1 and the second time stamp T2 is greater than a first preset time difference threshold, the server 13 determines to abandon writing the first registration message into the blockchain ledger, and broadcasts the abandoned first registration message into the blockchain network by broadcasting, and if a percentage of mining nodes in the blockchain network that exceeds a certain threshold, for example, 50%, broadcast the abandonment message for the first registration message, the first registration message will be regarded as invalid information in the blockchain, and the subsequent steps are not performed.
And 204, the mining node performs real-name authentication on the block chain participating node according to the first registration message and the second registration message.
Optionally, the mining node performs real-name authentication on the blockchain participating node according to the first registration message and the second registration message, including the following steps as shown in fig. 3:
When the server 13 receives the second registration message broadcasted by the terminal device 12, a fourth timestamp local to the server 13 when the server 13 receives the second registration message is recorded, and the fourth timestamp is denoted as T4, and further, the server 13 compares the third timestamp T3 with the fourth timestamp T4 in the second registration message.
When the time difference between the third time stamp T3 and the fourth time stamp T4 is less than or equal to a second preset time difference threshold, the server 13 queries, according to the identification information of the user in the second registration message, a first registration message corresponding to the identification information previously received by the server 13, obtains a first time stamp T1 from the first registration message, and compares the first time stamp T1 with the third time stamp T3.
In addition, if the time difference between the third timestamp and the fourth timestamp is greater than a second preset time difference threshold, the mining node determines to abandon writing the second registration message into the block chain ledger. For example, when the time difference between the third time stamp T3 and the fourth time stamp T4 is greater than a second preset time difference threshold, the server 13 determines to abandon writing the second registration message into the blockchain ledger, and broadcasts the abandoned second registration message into the blockchain network by broadcasting, and if a percentage of mining nodes in the blockchain network that exceeds a certain threshold, for example, 50%, broadcast the abandonment message for the second registration message, the second registration message is regarded as invalid information in the blockchain, and the subsequent steps are not performed.
When the time difference between the first time stamp T1 and the third time stamp T3 is less than or equal to a third preset time difference threshold, the server 13 performs image recognition on the video information in the second registration message to obtain the face information of the user in the video information and the head portrait information of the user in the identity card, compares the face information of the user in the video information with the head portrait information of the user in the identity card, and determines that the face information of the user in the video information is consistent with the head portrait information of the user in the identity card if the similarity between the face information of the user in the video information and the head portrait information of the user in the identity card is greater than the threshold.
And if the time difference between the first timestamp and the third timestamp is greater than a third preset time difference threshold value, the mining node determines to abandon the writing of the first registration message and the second registration message into a block chain ledger.
For example, when the time difference between the first time stamp T1 and the third time stamp T3 is greater than a third preset time difference threshold, the server 13 determines to abandon writing the first registration message and the second registration message into the blockchain ledger, and broadcasts the abandoned first registration message and abandoned second registration message into the blockchain network by broadcasting, and if a percentage of mining nodes exceeding a certain threshold in the blockchain network, for example 50%, broadcast abandonment messages for the first registration message and the second registration message, the first registration message and the second registration message will be invalid information in the blockchain, and no further steps are performed.
When the server 13 determines that the face information of the user in the video information is consistent with the head portrait information of the user in the identification card, the server 13 further compares whether the name of the user in the second registration message is consistent with the name in the first image information corresponding to the identification card in the video information, and compares whether the identification number of the user in the second registration message is consistent with the identification number in the first image information corresponding to the identification card in the video information.
And 305, if the name of the user in the second registration message is consistent with the name in the first image information and the identity card number of the user in the second registration message is consistent with the identity card number in the first image information, comparing the time information when the video information is recorded with the third time stamp by the mining node.
When the name of the user in the second registration message is consistent with the name in the first image information corresponding to the identity card in the video information, and the identity card number of the user in the second registration message is consistent with the identity card number in the first image information corresponding to the identity card in the video information, the server 13 further compares the time information when the video information is recorded with the third timestamp T3, that is, compares the time information dictated by the user in the video information with the third timestamp T3, or compares the time information displayed by the timer in the video information with the third timestamp T3.
When the time difference between the user-dictated time information in the video information and the third time stamp T3 is less than or equal to a fourth preset time difference threshold, the server 13 determines that the real-name authentication for the terminal device 12 is passed. After the server 13 determines that the real-name authentication of the terminal device 12 passes, the server 13 may further write the first registration message and the second registration message into the blockchain ledger, so that the real-name registration of the terminal device 12 is successful.
If the time difference between the user-dictated time information in the video information and the third time stamp T3 is greater than a fourth preset time difference threshold, the server 13 determines that the real-name authentication for the terminal device 12 has failed.
According to the embodiment of the invention, the mining node receives the first registration message broadcasted by the block chain participating node in the block chain network, the first timestamp of the local part of the block chain participating node included in the first registration message is compared with the second timestamp of the local part of the mining node when the mining node receives the first registration message, when the time difference between the first timestamp and the second timestamp is less than or equal to the first preset time difference threshold value, the mining node receives the second registration message broadcasted by the block chain participating node in the block chain network, the second registration message includes video information, and the video information includes user identity card picture information, user face information and the like, so that the mining node can uniformly verify the user and the user identity card, real-name authentication of the block chain participating node is realized, and the safety of the block chain network is improved.
