Embodiment 1

[0026] Collect the initial fingerprint pattern by the image acquisition module 4, enlarge the initial fingerprint pattern by 5 times by the image acquisition module 4, extract a clear original fingerprint sample with a size of 400*400mm pattern, and send the original fingerprint sample to the image analysis module 5, through the image The analysis module 5 divides the original fingerprint sample into 25 sub-fingerprint samples, extracts a fingerprint line as the reference fingerprint line of the sub-fingerprint sample from each sub-fingerprint sample, and any two reference fingerprint lines are different fingerprint lines; The fingerprint samples and their reference fingerprint lines are stored in the database 6 .

[0027] Gather new fingerprint patterns by image acquisition module 4, enlarge the pattern by 5 times, extract the fingerprint pattern with the clearest size of 200*200mm in the pattern as a comparison pattern, send the comparison pattern to image analysis module 5, ...

Embodiment 2

[0030] Collect the initial fingerprint pattern by the image acquisition module 4, enlarge the initial fingerprint pattern by 3 times by the image acquisition module 4, extract a clear original fingerprint sample with a size of 300*300mm pattern, and transmit the original fingerprint sample to the image analysis module 5, through the image The analysis module 5 divides the original fingerprint sample into 20 sub-fingerprint samples, extracts a fingerprint line as the reference fingerprint line of the sub-fingerprint sample from each sub-fingerprint sample, and any two reference fingerprint lines are different fingerprint lines; The fingerprint samples and their reference fingerprint lines are stored in the database 6 .

Abstract

The invention relates to a mobile phone finger print identifier, which comprises a machine case, a touch key and a controller, wherein the touch key is arranged on the surface of the machine case, the controller is arranged inside the machine case, the controller consists of an image collection module, an image analysis module, a database, an image comparison module and an image management module, and a warning device is arranged in the image management module. The method comprises the steps of carrying out initial finger print pattern collection, pattern application cutting, sample dividing, reference finger print line extraction and storage; and carrying out initial finger print pattern collection, pattern application cutting, reference finger print line extraction, pattern comparison, starting indication / warning and the like. The invention has the advantages of simple operation, high confidentiality and high safety. The invention has the owner uniqueness, the communication and the menu entering can be realized only through the press key of the finger print identifier, the data safety can be ensured to the highest degree, and the invention is favorable for the occurrence of the mobile phone stolen events.

Description

technical field [0001] The invention relates to a fingerprint recognition device, in particular to a mobile phone fingerprint recognizer with uniqueness and confidentiality recognition capability and a usage method applied to a mobile phone. Background technique [0002] Mobile phones in the prior art generally lock the SIM card or the mobile phone by means of a password. And there is no right to control operations such as calling and entering the menu, which will cause the mobile phone to be used by others after being lost or stolen, so that the stolen behavior of the mobile phone exists all the time, and the data in the mobile phone is not kept secret at all. Although it is possible to lock the SIM card or mobile phone with a password. However, due to its complicated operation and frequent forgetting of passwords, users generally do not use this function. Contents of the invention [0003] The object of the present invention is to provide a fingerprint reader for a mob...
