SM9 encryption-based fingerprint authentication method and device, and related equipment

Abstract

The embodiment of the invention discloses an SM9 encryption-based fingerprint authentication method and device and related equipment. The method comprises the steps: extracting a first IP address of aregistration end and inputted first fingerprint information, wherein the fingerprint input information comprises user data and the ordered fingerprint data of the user data; performing signature processing on the first IP address and the first fingerprint information by using an SM9 signature algorithm to obtain first signature data, and storing the first signature data; when an access request isreceived, obtaining verification information, wherein the verification information comprises a second IP address and second fingerprint information of an access end; performing signature processing on the verification information by using the SM9 signature algorithm to obtain second signature data; and verifying whether the first signature data is consistent with the second signature data, and ifso, passing the authentication. According to the method provided by the invention, the number of fingerprints is determined according to different security standards, the orderliness of the fingerprints is ensured, and meanwhile, the SM9 algorithm is adopted to perform signature encryption on the combined information, so that the confidentiality of data is ensured, and the security of data transmission is improved.

Description

technical field [0001] The present application relates to the technical field of fingerprint authentication, in particular to a SM9 encryption-based fingerprint authentication method, device and related equipment. Background technique [0002] With the formation of the concept of national security, the application of video surveillance has been fully rolled out from key areas to various economic fields of society. However, in the construction and application of my country's video surveillance system, there is a problem of "emphasizing construction, medium application, and ignoring security". Identity authentication technology is the first barrier of information system security. With the continuous development of monitoring system, the lack of more secure and efficient identity authentication technology becomes more obvious. [0003] Fingerprints have the characteristics of being easy to obtain and unique, and these two characteristics can be well used for identity authent...

AI Technical Summary

Problems solved by technology

However, precisely because the fingerprints of the human body are relatively easy to obtain, the leakage of fingerprints will bring huge losses.
