Embodiment 1

[0046] In this embodiment, a multi-fingerprint cross unlocking method is provided, and the steps are as follows: figure 1 As shown, including the following steps:

[0047] Step S10: Collect a first fingerprint image.

[0048] Step S20: the first fingerprint image is verified, and the collection and verification of the second fingerprint image is started after the first fingerprint image is successfully verified.

[0049] The multiple fingerprint images are verified one by one according to the preset combination sequence table, until the multiple fingerprint images are all verified within the preset time interval, the unlocking is successful. The preset time interval is a preset time interval that allows two adjacent The maximum time required for fingerprint image verification.

[0050] In this method, collecting multiple fingerprint images is based on one fingerprint collector or multiple fingerprint collectors. The fingerprint collector in this embodiment may use a fingerprint senso...

Embodiment 2

[0077] In the first scenario, the user is one person, that is, multiple captured images come from different fingers of the same person. The device based on the multi-fingerprint cross-adding / unlocking application system is equipped with a fingerprint sensor, and the user performs multiple operations on the fingerprint sensor. (E.g. 10) Finger fingerprint information is registered and saved as template fingerprint information, using cross-type setting to lock and protect. Specifically, taking the registration of three finger fingerprint information as an example for description, the three finger fingerprint information codes registered by the user on the fingerprint sensor are set as a, b, and c. The password is set by cross-type random permutation and combination, namely abc, acb, bac, bca, cab, cba.

[0078] When the device password is set to abc, if you need to access or operate the device, the decryption procedure is as follows: first verify fingerprint information a, verify f...

Embodiment 3

[0080] In the second scenario, the user is multiple people, that is, multiple captured images are from the fingers of the same multiple people, and a device based on the multi-fingerprint cross-adding / unlocking application system is used to configure the fingerprint sensor. People with different identities (such as: A and B) Register the fingerprint information on the fingerprint sensor and save it as template fingerprint information, and use the cross-type setting to lock and protect. Specifically, A and B have the right to access or operate the device. A and B respectively register fingerprint information codes as A and B on the fingerprint sensor of the electronic device. The password of the device can be set to AB or BA. In particular, when there are more than 2 people registering fingerprint information, their registered fingerprint codes are A, B, C..., and the password of the device can be set by cross-random arrangement and combination, namely ABC, ACB, BAC, BCA , CAB, ...

Abstract

The invention discloses a multi-fingerprint cross-unlocking method and system. The multi-fingerprint cross-unlocking method comprises the following steps: acquiring a first fingerprint image; verifying the first fingerprint image, and after successful verification of the first fingerprint image, starting acquisition and verification of a second fingerprint image; acquiring the verifying a plurality of fingerprint images one by one according to a preset combination sequence list, and achieving successful unlocking till all the fingerprint images pass the verification within a preset time interval, wherein the preset time interval is the maximum time which is set in advance and allows every two adjacent fingerprint images to be verified. According to the multi-fingerprint cross-unlocking method and system, a device is cross-locked / unlocked through multiple fingerprints of the same or different people; as multiple fingerprints are involved, the multiple fingerprint images need to be verified one by one according to the preset combination sequence list during unlocking; successful unlocking can only be achieved according to the preset sequence, so that the unlocking security is improved; the multi-fingerprint cross-unlocking method and system can be suitable for devices with higher security or access control systems on special occasions.

Description

Technical field [0001] The invention relates to the technical field of fingerprint control, in particular to a method and system for cross-unlocking multiple fingerprints. Background technique [0002] With the continuous advancement of technology, biometrics (such as human face, fingerprint, eyes, etc.) are gradually being used in the electronic field and access control systems, etc. The use of biometric identification for encryption / decryption is very convenient, which can save the trouble of entering passwords. , It also reduces the risk of misappropriation due to its biological characteristics. [0003] Compared with face recognition and iris recognition, the operation of fingerprint unlocking is relatively simple, so fingerprint recognition technology is especially popular among people. However, the current fingerprint locks that use fingerprint information as the unlocking identification are usually realized by a separate fingerprint. For some important devices that require ...
