User identity authentication method for intelligent mobile terminal

Abstract

The invention discloses a user identity authentication method for an intelligent mobile terminal, by designing a special movement operation manner of the mobile terminal, active movement of the mobile terminal and screen touching operation are organically combined; by using various sensor behavior data and screen touching behavior data generated during authentication operation of a user, a characteristic vector sequence of a mapping relation between a finger screen touching track and a space pose position of the mobile terminal is established based on a screen touching geodesic distance of the user, so as to judge legality of user identity. The user identity authentication method has the advantages: the operation is simple, and no additional extra equipment need to be increased; behavior characteristics with space translation and rotation invariance are put forward, and influence of change of poses such as rotation and translation of the mobile terminal on an authentication result is effectively avoided.

Description

technical field [0001] The invention relates to a user identity authentication technology, in particular to an authentication method for an intelligent mobile terminal user identity. Background technique [0002] With the progress of society, people pay more and more attention to security and identity information, and the demand for biometric technology continues to expand. Research and development of an identification system with reliable performance and simple operation has gradually become a hot spot in current technology research. [0003] There are many authentication technologies on smart terminals that are popular in the market today: handwriting recognition and speech recognition are not accurate enough and are easy to be reproduced by others; Interference with physiological factors, poor stability; fingerprint, pupil, iris recognition security and accuracy are high, but need to provide special hardware equipment support, high cost; some identity authentication meth...

Problems solved by technology

[0003] There are many authentication technologies on smart terminals that are popular in the market today: handwriting recognition and speech recognition are not accurate enough and are easy to be reproduced by others; Interference with physiological factors, poor stability; fingerprint, pupil, iris recognition security and accuracy are high, but need to provide special hardware equipment support, high cost; some identity authentication methods based on single sensor data such as gyroscope will be Affected by attitude changes such as rotation and translation of the mobile terminal, and the behavior characteristics are unstable and the data is noisy

[0004] Recently, there have also been authentication methods that use multi-finger touch data to extract hand features, but these methods can only extract simple hand features such as finger length difference and finger spacing, and in some cases cannot distinguish all users
