Embodiment Construction

[0023] In order to solve the problems of low security and poor usability of SIM unlocking methods in the prior art, the embodiments of the present invention provide a method for managing user identification card rights and a terminal device.

[0024] Such as figure 1 As shown, the method for user identification card authority management provided by the embodiment of the present invention includes:

[0025] Step 101, collecting fingerprint information input by the user;

[0026] Step 102, comparing the input fingerprint information with the fingerprint template;

[0027] Step 103, when the input fingerprint information matches the fingerprint template, extract the PIN code corresponding to the fingerprint template through the corresponding relationship between the fingerprint template and the PIN code;

[0028] Step 104, using the corresponding PIN code to unlock the SIM card.

[0029] The step 104 includes: when the corresponding PIN code is consistent with the PIN code sto...

Abstract

The embodiment of the invention discloses a right management method for user identification card and a terminal unit, which relates to the filed of communication, and solves the problem of the prior art that the safety of the SIM unlocking method is low and availability is poor. The technical of the invention comprises: acquiring the fingerprint information inputted by the user; comparing the inputted fingerprint information and the fingerprint template; extracting the personal identification code corresponding to the fingerprint template through the correspondence relationship of the inputted fingerprint information and the fingerprint template; and unlocking the user identification card thorough the corresponding personal identification code. The technical scheme provided by the embodiment of the invention can be applied to various electronic products such as cellphones containing SIM card, data card and the like.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for managing rights of a user identification card and a terminal device. Background technique [0002] The Subscriber Identity Module (SIM card) is a smart card containing a large-scale integrated circuit, which is used to register user identification data and information. Four types of data are stored in the SIM card, including a personal identification number (Personal Identification Number, PIN code). [0003] In the prior art, the SIM card is encrypted by a PIN code, and the PIN code is the personal identification code of the SIM card. Before the user modifies each SIM card, its original PIN code is 1234 or 0000, which is set by the operator. In order to prevent the SIM card in the terminal device from being stolen due to the loss of the terminal device, the user can enable the PIN code and reset the PIN code by inputting the original PIN code. After the PIN code is e...
