Abstract

The invention relates to the fields of cell phone communication safety and biological recognition. A fingerprint recognition method based on an intelligent mobile information device comprises the following steps: turning on a camera of the intelligent mobile information device to collecting fingerprint image information by a non-contact manner within a predetermined range; scaling the collected image to ensure the collected image is in the same proportion to a prestored template; rotating the angle of the finger image into a proper position, extracting fingerprint characteristics; matching the extracted fingerprint characteristics with the prestored template; executing predetermined corresponding functions if the extracted fingerprint characteristics are matched with the prestored template, otherwise ending the operation. The non-contact fingerprint recognition can be achieved at the a cell phone without contacting a collector end face upon collecting the fingerprint image, accordingly reducing the possibility of propagating pathogenic bacteria, and ensuring the consistency in the recognition structure without extra hardware collecting equipment having a higher cost.

Description

technical field [0001] The invention relates to the technical field of mobile phone communication security and biological identification, in particular to a fingerprint identification method based on an intelligent mobile information device. Background technique [0002] Apple has opened the era of touch screen, and touch screen mobile phone has become people's new favorite. The terminal of mobile phone development is "one phone in hand, travel anywhere in the world". For example, the water heater at home can be turned on remotely through the mobile phone, the bank transfer service can be performed through the mobile phone, and the identification can be carried out through the mobile phone. This small mobile phone stores a huge amount of information, which greatly facilitates and simplifies people's lives. But the problem of hidden dangers will follow, that is, the problem of safety. Most of the current mobile phones are unlocked by multi-touch or decrypted by simple digi...
