Detailed Description
The present invention is described below with reference to the accompanying drawings, but the present invention is not limited thereto.
Fig. 1 is a schematic flow chart of an identity verification method based on a block chain according to the present invention, which includes:
s1: acquiring first tongue print information to be matched, and preprocessing the first tongue print information.
The first tongue print information is user information of an identity to be verified, and the first tongue print information is collected in a non-contact mode through an ultrasonic device. The preprocessing is used for signal filtering processing, such as signal filtering processing and the like, on the acquired tongue print information.
Specifically, as shown in fig. 2, the method for acquiring the tongue pattern is explained as follows:
the ultrasonic sensor is excited by applying a pulse voltage to the sensor, causing the sensor to emit an ultrasonic pulse. Since the incident sound wave is reflected and transmitted while passing through different media or significant acoustic impedances, the transmittance is almost 0 when the difference between the acoustic impedances of the two media is large, and the sound wave is almost totally returned. When the tongue veins are identified by ultrasonic waves, the difference of acoustic impedances of two mediums (air and tongue coating) is large, and tongue vein characteristics can be established according to the change of reflected waves on information such as amplitude, phase and the like, and the determination comprises the following steps: the position of the tongue, filiform papillae, fungiform papillae, foliate papillae, and generate a 3-dimensional tongue streak image.
The information of the user tongue print is obtained through the ultrasonic identification module, the computer distributes the unique ID, the unique ID is uploaded to the block chain after being encrypted through the secret key, the identity card number is matched for data storage, and the real reliability of the data is protected by using the characteristic that the block chain cannot be tampered.
S2: and encrypting the preprocessed first tongue print information, uploading the encrypted first tongue print information to a block chain, and comparing the encrypted first tongue print information with second tongue print information stored in advance in the block chain.
The second tongue print information is tongue print information which is collected in advance and stored in the memory of the block chain, and tongue print information of a plurality of users (namely, the second tongue print information of the present invention) exists in the block chain. After the second tongue print information is collected by the ultrasonic identification module, ID information is configured for the second tongue print information; adding a key to the second tongue print information and the ID information, and uploading the second tongue print information and the ID information added with the key to a block chain; and matching the second tongue print information and the ID information with the identity card number for storage.
S3: and if the comparison is successful, acquiring personal information associated with the second tongue print information, and feeding back the personal information.
When the user identity needs to be checked and the first tongue print information of the user needs to be obtained again, the comparison with the existing second tongue print information in the block chain is needed, after the comparison is successful, the personal information of the user can be pulled from the block chain, and the information which is successfully extracted is fed back to the user. If the comparison is unsuccessful, the identity verification is prompted to fail.
