AI Technical Summary

Problems solved by technology

In an open wireless network, many application systems require a reliable identity authentication mechanism, and some data resources also require different access rights to be set according to the identity of the user. Now the commonly used identity identification method is a password. Its disadvantages are that it is not safe. It may be cracked or leaked; the second is inconvenient, modern people often worry about remembering a large number of passwords

Embodiment 1

[0081] Embodiment 1: Mobile phone car key based on palmprint recognition

[0082] Embed non-contact IC chip in the mobile phone, just can have remote control function, and this is prior art. In this example, the user chooses to use the mobile phone as the key of the car, and writes the corresponding secret information (which can be a key) in the car lock and the IC chip of the mobile phone. Assume that the mobile phone IC chip has the following characteristics:

[0083] One is protected, the internal information cannot be deciphered;

[0084] The second is controllable, and the transmission of radio frequency information can be started or stopped with control commands.

[0085] The advantage of above-mentioned mobile phone car key is convenient, and general user has mobile phone, needn't carry car key to go out in addition. But if the user loses his phone, his car is also at risk of being stolen.

[0086] If a set of palmprint recognition application module is installed on...

Embodiment 2

[0096] Criminals with previous convictions will collect their palmprint characteristics when they enter prisons or public security bureaus, and a central palmprint database for criminals will be established nationwide, which will be dynamically updated through wired or wireless networks. Each suspect has 3 images on each palm, and the feature size of each palmprint image is 512 bytes. Assuming that 10 million suspects’ palmprint features are collected, the storage space of the database is about 30G bytes. The capacity of the hard disk is generally 80G to 200G, which is enough to record the central palmprint database of all criminals in the country. The policeman on patrol is equipped with a mobile palmprint recognition system, that is, palmprint recognition software and communication software are installed on the PDA. If a suspicious fugitive is seen on the street, the police can use the camera on the PDA to collect the palmprint image of the suspect, automatically extract the...
