Problems solved by technology

[0004] At present, in the existing encryption and decryption system, the application processor performs the decryption process after the fingerprint identification is passed, and the application processor needs to obtain the user fingerprint and the pre-stored verification fingerprint from other different modules respectively when performing fingerprint identification. In the process of obtaining verification fingerprints from other modules, verification fingerprints are often at risk of being tampered with, reducing data security

Abstract

The invention discloses a fingerprint decryption method. The fingerprint decryption method includes: acquiring a user's fingerprint through a fingerprint recognition module; sending the user's fingerprint to a safety module; checking the user's fingerprint according to a preset checking fingerprint through the safety module, wherein the checking fingerprint is stored in the safety module; when checking is successful, decrypting data to be decrypted. Comparison checking is performed between the checking fingerprint preset in the safety module and the user's fingerprint sent by the fingerprint recognition module, when the checking is successful, the data to be decrypted are decrypted, risk that the preset checking fingerprinted is modified is lowered, and safety of the data is improved.

Description

technical field [0001] The invention relates to the field of data encryption, in particular to a fingerprint decryption method and system. Background technique [0002] With the development of science and technology, a large amount of data needs to be transmitted and stored. In order to ensure that the data is prevented from being stolen by others during the process of transmission or storage, resulting in the leakage of confidentiality, it is often necessary to encrypt the data. At present, data encryption methods are becoming more and more diverse, for example, fingerprint recognition, palmprint recognition, iris recognition, facial recognition and so on. [0003] Fingerprints are the uneven lines on the skin at the end of a person's fingers. The lines are arranged regularly to form different grain patterns. The starting point, ending point, joint point and bifurcation point of the ridge line are called the detail feature points of the fingerprint. Fingerprints are som...
