Problems solved by technology

However, data encryption is a computationally intensive operation that consumes a large amount of CPU time. Therefore, encrypting the entire fingerprint feature template requires a large amount of encryption calculations and low efficiency; at the same time, the encrypted fingerprint feature template is integrated Storage, once the stored data is leaked, the entire encrypted fingerprint feature template will be leaked, and the storage security is low

Abstract

The invention discloses a fingerprint feature template encrypted storage method and system of a mobile terminal. The method comprises the following steps: classifying fingerprint feature templates to obtain N sub-templates, wherein N is greater than or equal to 2 and each sub-template in the N sub-templates corresponds to fingerprint feature data of a different type; encrypting M sub-templates in the N sub-templates, wherein M is smaller than N; and storing the encrypted M sub-templates and the unencrypted sub-templates to a storage area. Compared with encrypting the whole fingerprint feature templates in the prior art, in the fingerprint feature template encrypted storage method, only partial sub-templates in the N sub-templates are encrypted, and therefore, the calculation amount is remarkably reduced under the premise that the data security is guaranteed, and the encryption efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data encryption storage, in particular to a fingerprint feature template encryption storage method and system for a mobile terminal. Background technique [0002] Today, due to the lifelong invariance, uniqueness and convenience of fingerprints, fingerprint recognition technology is more and more widely used in daily life, such as identity verification when clocking in and out of get off work, unlocking mobile phones or transferring money, etc., especially Applications on mobile terminals such as mobile phones and tablets, which have a relatively high usage rate in daily life, are also becoming more and more extensive. [0003] In fingerprint recognition technology, it is necessary to read out the feature data in the fingerprint image and store it as a template, which we call a fingerprint feature template. The fingerprint features stored in the fingerprint feature template include ridge spacing, ridge cu...
