Abstract

A user identity recognition method for a mobile terminal includes that: a mobile terminal detects and tracks a user'"'"'s behavior before a Subscriber Identity Module (SIM) card is replaced, and records characteristics of the user'"'"'s behavior; after the SIM card is replaced, the mobile terminal detects and tracks a user'"'"'s behavior and records characteristics of the user'"'"'s behavior; the mobile terminals determines whether the characteristics of the user'"'"'s behavior before the SIM card is replaced are same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced; if so, the mobile terminals determines that the user is a legal user; otherwise, the mobile terminals determines that the user is an illegal user. Correspondingly, a mobile terminal is also disclosed, which is difficult to crack, more secure, and easy and convenient to implement.

Claims

1. A user identity recognition method for a mobile terminal, comprising:

detecting, by a mobile terminal, and tracking a user'"'"'s behavior before a Subscriber Identity Module (SIM) card is replaced, and extracting characteristics of the user'"'"'s behavior from the detected and tracked user'"'"'s behavior;

after the SIM card is replaced, detecting and tracking a user'"'"'s behavior and extracting characteristics of the user'"'"'s behavior; and

determining whether the characteristics of the user'"'"'s behavior before the SIM card is replaced are same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced;

when the characteristics of the user'"'"'s behavior before the SIM card is replaced are same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced, determining that the user is a legal user; and

when the characteristics of the user'"'"'s behavior before the SIM card is replaced are not same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced, determining that the user is an illegal user,

wherein the characteristics of the user'"'"'s behaviour comprises a first-level determination characteristic for roughly recording identity characteristics of the user and a two-level determination characteristic for precisely describing the identity characteristics of the user,

wherein the user'"'"'s behavior comprises a movement behavior and an operation behavior,

wherein user'"'"'s behavior characteristics of the movement behavior comprise home position information, company position information, home-company distance information, information of the user'"'"'s commute time slot, and information of the user'"'"'s commuting time to work, and

wherein the operation behavior is one of the following;

a voice operation, an Internet access operation, a short messaging service operation, a telephone book operation, an STK operation, a game operation, a player operation, a camera operation, an electronic reading operation and a charging operation.

2. The method according to claim 1, wherein when the operation behavior is the voice operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a number type, time slot and duration;

when the operation behavior is the short messaging service operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a number type and time slot;

when the operation behavior is the Internet access operation, characteristics corresponding to the user'"'"'s behavior comprise an access mode, time slot, online behavior and duration;

when the operation behavior is the telephone book operation, characteristics corresponding to the users behavior comprise an operation type, a number type and time slot;

when the operation behavior is the STK operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type and time slot;

when the operation behavior is the game operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, time slot and duration;

when the operation behavior is the player operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a multimedia type, time slot and duration;

when the operation behavior is the camera operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, time slot and duration;

when the operation behavior is the electronic reading operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, time slot and duration; and

when the operation behavior is the charging operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, time slot and duration.

3. A mobile terminal, comprising:

a behavior detecting and tracking module, a behavior characteristic extraction module, a behavior characteristic comparison module and a determination module, wherein

the behavior detecting and tracking module is configured to detect and track a user'"'"'s behavior before and after a Subscriber Identity Module (SIM) card is replaced, to provide data for extraction of behavior characteristics;

the behavior characteristic extraction module is configured to extract characteristics of the user'"'"'s behavior from the detected and tracked user'"'"'s behavior before and after the SIM card is replaced;

the user characteristic comparison module is configured to compare the characteristics of the user'"'"'s behavior before the SIM card is replaced with the characteristics of the user'"'"'s behavior after the SIM card is replaced; and

the determination module is configured to determine, according to the comparison result transmitted from the user characteristic comparison module, whether the user is a legal user, when the characteristics of the user'"'"'s behavior before the SIM card is replaced are same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced, determine that the user is a legal user, and when the characteristics of the user'"'"'s behavior before the SIM card is replaced are not same as or similar to the characteristics of the user'"'"'s behavior after the SIM card is replaced, determine that the user is an illegal user,

wherein the characteristics of the user'"'"'s behaviour comprises a first-level determination characteristic for roughly recording identity characteristics of the user and a two-level determination characteristic for precisely describing the identity characteristics of the user,

wherein the user'"'"'s behavior comprises a movement behavior and an operation behavior,

wherein user'"'"'s behavior characteristics of the movement behavior comprise home position information, company position information, home-company distance information, information of the user'"'"'s commute time slot, and information of the user'"'"'s commuting time to work, and

wherein the operation behavior is one of the following;

a voice operation, an Internet access operation, a short messaging service operation, a telephone book operation, an STK operation, a game operation, a player operation, a camera operation, an electronic reading operation and a charging operation.

4. The mobile terminal according to claim 3, wherein when the operation behavior is the voice operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a number type, time slot and duration;

when the operation behavior is the short messaging service operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a number type and time slot;

when the operation behavior is the Internet access operation, characteristics corresponding to the user'"'"'s behavior comprise an access mode, time slot, online behavior and duration;

when the operation behavior is the telephone book operation, characteristics corresponding to the user'"'"'s behavior comprise an operation type, a number type and time slot;
