An unlocking method and system for an intelligent mobile terminal

Abstract

The invention discloses an unlocking system for a mobile terminal. The system comprises a function setting module, a dynamic keyboard claiming module, an unlocking module and a function verification module. An unlocking method for the mobile terminal includes the steps of 1, setting the finger sliding directions corresponding to digital passwords and digital keys; 2, performing unlocking and 3 performing verification. The unlocking method and system for the mobile terminal are high in applicability, the digital passwords which are popular among most users are still used, the continuous sliding unlocking function is added on the basis that user habits are not changed, operation is simple, convincement and rapid, and user experience is good. The unlocking method and system for the mobile terminal are extremely high in safety, the corresponding sliding directions of fingers on the digital keys are added on the basis of the traditional digital passwords, password space is increased greatly so as to lower brute force attack risks, meanwhile, a dynamic claiming digital keyboard is used for preventing smudge attacks, and the safety is further improved.

Description

technical field [0001] The invention relates to an unlocking method and system for an intelligent mobile terminal, belonging to the technical field of computer science. Background technique [0002] Compared with traditional devices, with the increasing number of sensing devices attached to smart terminals (touch screen, gravity, angular velocity, camera and other sensors), and the substantial increase in interaction with users during the application of smart terminals, at the same time, Based on the continuous enhancement of the processing capability of intelligent terminals, the realization of the authentication mode based on body or user behavior recognition gradually has a hardware foundation. Therefore, authentication modes based on body or user behavior recognition are increasing in both types and application scope. Therefore, the user verification method of smart terminals has also developed from a single "key unlock" in the past to a variety of unlocking and authent...

AI Technical Summary

Problems solved by technology

[0003] 1. Knowledge-based: the common one is sliding unlock, which is convenient and fast but has no security at all;

[0004] 2. Other components held by the user: such as an unlocking method based on NFC tags, but this unlocking requires additional auxiliary hardware and requires smart terminals to support NFC communication functions;

[0005] 3. Based on user characteristics: for example, facial recognition unlocking, taking photos through the front camera of the smart terminal, and unlocking through picture matching, but this unlocking method is easily affected by light, and it takes a long time to unlock;

To sum up, compared with the other two types of authentication methods, the knowledge-based authentication method does not require hardware support, but its security and operability are not as good as the latter two types

The latter two types of authentication methods do not require the user to remember the password, but the object-based authentication method has the problem of password loss, and the body-based authentication method takes a long time and may be affected by the environment
