Embodiment Construction

[0041] The fingerprint authentication method based on continuous variable quantum key distribution provided by the present invention realizes the working principle of the scheme based on continuous variable quantum key distribution; the method of the present invention is mainly divided into two stages, the first stage is user fingerprint identity In the registration stage, the second stage is the user fingerprint identification stage. Because the method of the present invention does not directly transmit the user's fingerprint identity information, but modulates the fingerprint feature points into coherent state variables, generates an initial key through a correspondingly generated revocable template, and then passes through a series of post-processing processes (including parameter estimation, The process of reverse error correction negotiation and key strengthening) finally obtains the encryption key, so that the whole system has better security and privacy.

Abstract

The present invention discloses a fingerprint authentication method based on continuous variable quantum key distribution. The method comprises a registering phase and an authentication phase. The registering phase is configured to register the user fingerprint information, and the authentication phase is configured to authenticate the user fingerprint information. The fingerprint authentication method based on continuous variable quantum key distribution has an unconditional safety in theory based on the continuous variable quantum key distribution process, according to the method, the information transmitted between a client and a server is not information of feature points of user fingerprint so that the user information safety is not influenced even if the transmission information is stolen. The method improves the safety of the same user employing the same fingerprint cross-platform authentication, and can ensure the safety of the whole system when the key is lost or reset and theuser employs the same fingerprint to perform registration and authentication again.

Description

technical field [0001] The invention belongs to the field of quantum communication, in particular to a fingerprint authentication method based on continuous variable quantum key distribution. Background technique [0002] With the development of biotechnology and artificial intelligence technology, the level of fingerprint recognition technology is constantly improving, and it is widely used in various public places. Compared with traditional authentication methods such as passwords and character strings, fingerprint identification is simpler and more convenient. The fingerprint identification method does not need to remember the password, and the identity authentication process can be completed only by scanning the user's fingerprint. But biometric technology is not equal to absolute security, and there are several inherent problems in it. For example, the original feature data of fingerprints are called "feature points" and are stored in the database of the server. If t...
