Abstract

The invention relates to the field of mobile phone communication safety and biological recognition, in particular to a fingerprint detection method based on intelligent mobile information equipment. The fingerprint detection method comprises the steps of starting a camera of the intelligent mobile information equipment for collecting finger image information in a noncontact mode within the preset distance range; preprocessing a collected finger image, and conducting automatic segmentation and background stripping on the size of the finger; rotating the angle of the finger image to be at the proper position, and extracting fingerprint characters; matching the obtained fingerprint characters with prestored templates; if the obtained fingerprint characters are matched with the prestored templates successfully, executing corresponding set functions; if the obtained fingerprint characters are not matched with the prestored templates, the step is ended. Noncontact fingerprint recognition can be achieved by means of a mobile phone terminal, the end face of a collector does not need to be touched during fingerprint image collection, the probability of pathogenic bacterium spread is decreased, and meanwhile no extra hard collection equipment with the high cost is needed.

Description

technical field [0001] The invention relates to the technical fields of mobile phone communication security and biological identification, in particular to a fingerprint detection 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 digital ...
