Living fingerprint detection method based on intelligent mobile information equipment

Abstract

The invention relates to the safety and biological recognition field and discloses a living fingerprint detection method based on intelligent mobile information equipment. The living fingerprint detection method based on the intelligent mobile information equipment includes that starting a camera to gather fingerprint image information in a non-contact mode in a preset distance range; continuously photographing at least two times in a certain preset time period to obtain at least two images; pre-processing the images, performing bio-assay, if the body is a living body, entering the next step, otherwise, ending; extracting fingerprint characteristics; matching the fingerprint characteristics with a pre-stored template, if the fingerprint characteristics are matched with the pre-stored template, executing the set corresponding functions, otherwise, ending. The living fingerprint detection method based on the intelligent mobile information equipment does not need to contact with the head face of a gatherer when using a mobile phone to gather fingerprint images, the pathogenic bacterium transmission probability is reduced, and meanwhile, the highest level of safety fingerprint identification of the mobile phone is realized through the bio-assay, an implant is avoided, and the safety of the fingerprint log-in, payment and the like on the mobile phone is greatly improved.

Description

technical field [0001] The invention relates to the technical fields of communication security and biometric identification, in particular to a fingerprint living body 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 se...
