Description

User identification card authority management method and terminal device The application is submitted to the Chinese Patent Office on November 27, 2009, and the application number is CN 200910226269. 0, the invention name is "user identification card authority management method and terminal device" in China Priority of the patent application, the entire contents of which is incorporated herein by reference. TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a method and a terminal device for managing user rights of a towel user identification card. BACKGROUND A Subscriber Identity Module (SIM) is a smart card containing a large-scale integrated circuit for registering user identification data and information. There are four types of data stored in the SIM card, including personal identification number (Personal Identification Number, PIN code).

In the prior art, the SIM card is encrypted by a PIN code, which is a personal identification code of the SIM card. Before the SIM card is modified by the user, its original PIN code is 1234 or 0000, which is set by the operator. In order to prevent the SBi card in the terminal device from being stolen due to the loss of ten terminal devices, the user can enable the PIN code and reset the PIN code by inputting the original PIN code. After the PIN code is enabled, the terminal device with the SIM card needs to input the power-on password, that is, the PIN code, each time the device is turned on. Only when the password is input correctly, the terminal device can enter the normal use state. Otherwise, the wrong power-on password is entered three times in succession. The SIM card will be locked, which reduces the probability of the SIM being stolen by others.

In the process of implementing the present invention, the inventor has found that if the PIN code is turned on, the user needs to input a PIN code to unlock each time the terminal device with the SIM card is turned on, which easily causes the PIN code to be easily leaked. Therefore, the SIM card unlocking method in the prior art has low security and poor usability. Summary of the invention

The embodiment of the invention provides a method for managing the rights of the user identification card and the terminal device, so as to solve the problem that the SIM unlocking method has low security and poor usability in the prior art.

In order to solve the problem in the prior art that the security of the SIM unlocking method is low and the availability is poor, the embodiment of the invention provides a method for managing the rights of the user identification card and the terminal device.

As shown in FIG. 1 , a method for managing rights of a user identification card according to an embodiment of the present invention includes: Step 101: Collect fingerprint information input by a user;

Step 102: Compare the input fingerprint information with the fingerprint template:

Step 103: When the input fingerprint information matches the fingerprint template, extract a PIN code corresponding to the fingerprint template by using a correspondence between the fingerprint template and the PIN code;

Step 104: Unlock the SIM card by using the corresponding PIN code.

The step 104 includes: when the corresponding PIN code is consistent with the PIN code saved in the SIM card, the SB1 card is successfully unlocked.

The method for managing the rights of the user identification card provided by the embodiment of the present invention, when the input fingerprint information matches the fingerprint template, the PIN code corresponding to the fingerprint template is extracted by the correspondence between the fingerprint template and the PIN code, so that the user When the PIN code is enabled, only the fingerprint is required to be input. In the prior art, the PIN code is enabled, and the user needs to input the PIN code every time to open, so that the PIN code is easy to leak, the terminal device is turned on, and the user forgets the power-on password. The problem that caused the SIM card to be locked. The technical solution provided by the embodiment of the present invention, when inputting fingerprint information When the fingerprint template is matched, the PIN code corresponding to the fingerprint template is extracted by the correspondence between the fingerprint template and the PIN code, so that only the fingerprint can be input when the PIN code is enabled, and the PIN code leakage is reduced. The probability of the SIM card is improved, and the use is convenient, and the situation that the user forgets the PIN code to cause the SIM card to be locked is avoided, and the availability of the SIM card unlocking is improved. In order to enable a person skilled in the art to more clearly understand the technical solutions provided by the embodiments of the present invention, the fingerprint encryption method provided by the embodiments of the present invention will be described in detail below through specific embodiments.

As shown in FIG. 2, the method for managing user identity card rights according to another embodiment of the present invention includes: Step 201: Pre-establish a correspondence between a fingerprint template and a PIN code;

Step 202: Collect fingerprint information input by the user.

Step 203: Compare the input fingerprint information with the fingerprint template.

Step 204: When the input fingerprint information matches the fingerprint template, extract a PIN code corresponding to the fingerprint template by using a correspondence between the fingerprint template and the PIN code;

Step 205: Unlock the STM card by using the corresponding PTN code.

In step 205, when the corresponding PIN code is consistent with the PIN code stored in the SIM card, the SIM card is successfully unlocked.

In addition, the step 202 may further include: Step 206, prompting to input a PIN code. In the pop-up PIN code input interface, to prompt for the PIN code, the user can directly input the fingerprint, or input the PIN code set by the user. When the user inputs the fingerprint in step 206, the process proceeds to step 202. When the user inputs the set PIN code in step 206, the user identification card is successfully unlocked, and the SIM card is unlocked.

As shown in FIG. 3, the step 201 may specifically include steps 301 to 305:

Step 301: Generate a fingerprint template according to the fingerprint information collected for the first time.

The step 301 may further include: Step 305: input an original PIN code, where the original PIN code includes an original PIN code, an original password set by an operator; or a boot PIN code, and a PIN set by the user last time. code. In the case that the user does not modify the PIN code, the original PIN code is the original PIN code set by the operator, which is generally 1234 or 0000. Here, the PIN code is taken as an example for example. In actual use, it can be used as needed. Set the PIN code to one or more digits, and the PIN code is not limited to numbers, but also letters or other symbols. At this time, the user inputs the original PIN code in the pop-up interface for prompting to input the PIN code, and proceeds to step 301. In the case that the user has modified the PIN code, the user inputs the power-on PIN code, that is, the PIN code set by the user last time, in the pop-up prompting to input the PIN code, and proceeds to step 301. Step 302: Set a new PIN code according to a user input;

In step 302, a new PIN code is set according to the four digits input by the wide input. For example, if the wide input 5746 is used, the number "5746" is the set new PIN code. It should be noted that the set new PIN code and the original PIN code in the SIM card may have the same or different digits.

Step 303: The new PIN code is replaced with the original PIN code and saved in the SIM card.

In step 303, the new PIN code set in step 302, such as "5746", is replaced with the original PIN code, such as "1234", and stored in the SIM card, that is, the original PIN originally saved in the SIM card. The code is the default PIN code "1234" set by the operator. After the step 303, the new PIN code "5746" set in the step 302 is saved in the SIM card.

In addition, in step 303, when there is no default PIN code in the SIM, the set new PIN code may be directly saved in the user identification card as the PIN code of the SIM without performing the replacement operation. At this time, since there is no default PIN code in the SIM card, the PIN code input by the user is directly used as the set new PIN code.

Step 304: Establish a correspondence between the fingerprint template and the new PIN code.

In this embodiment, the correspondence between the fingerprint template and the new PTN code is established through steps 301 to 305, so that the user only needs to input the fingerprint when the new PIN code is enabled.

The method for managing the rights of the user identification card provided by the embodiment of the present invention, when the input fingerprint information matches the fingerprint template, the PIN code corresponding to the fingerprint template is extracted by the correspondence between the fingerprint template and the PIN code, so that the user When the PIN code is enabled, only the fingerprint is required to be input, which reduces the probability of PIN code leakage, improves the security of the SIM card unlocking, and is convenient to use, thereby avoiding the situation that the user forgets the PIN code and causes the SIM card to be locked, thereby improving The availability of SIM card unlocking. In order to further reduce the probability of PIN code leakage, another embodiment of the present invention provides a method for managing user rights of a user identification card. The method of this embodiment differs from the previous embodiment in that: 201, that is, the correspondence between the fingerprint template and the PIN code is established in advance, and specifically includes steps 401 to 405.

Step 401: Generate a fingerprint template according to the fingerprint information collected for the first time. The specific implementation method of the step 401 is the same as the step 301 shown in FIG. 3, and details are not described herein again.

Step 402: Map the fingerprint template to an encoding.

Step 403, setting a new PIN code according to the user input and the encoding;

In this embodiment, the setting of the new PIN code may be performed by randomly extracting four random numbers in the code and adding four digits input by the user, and taking the last four digits as a PIN code. For example, randomly extracting numbers from the code, Go to "3521" and the four digits entered by the user are "9654", then add "13175" and the PIN code is "3175". It is worth noting that different operators can set different algorithms to implement the setting of the PIN code, and are not limited to the above ones, and are not described here.

Step 404: The new PIN code is replaced with the original PIN code and saved in the SIM card. The specific implementation of the step 404 is the same as the step 303 shown in FIG. 3, and details are not described herein again.

In addition, in step 404, when there is no default PIN code in the SIM, the set new PIN code may be directly saved in the user identification card as the PIN code of the SIM, without performing the replacement operation. At this time, since there is no default PIN code in the SIM card, the PIN code input by the user and the PIN code generated by the encoding by the certain algorithm are directly used as the set new PIN code.

Step 405: Establish a correspondence between the fingerprint template and the new PIN code. The specific implementation of the step 405 is the same as the step 304 shown in FIG. 3, and details are not described herein again.

In this embodiment, according to the input of the user and the encoding, a new PIN code is set, and the set new PIN code is not known by the user. In the above step 206, although the PIN code is prompted, the pop-up is popped up. When the PIN code is input to prompt the input of the PTN code, the user cannot unlock the STM card by directly using the PTN code because the PTN code is unknown. Only by inputting the fingerprint, the fingerprint is input, and the above step 202 is entered. Therefore, the number of times the user inputs the PIN code is reduced, and the probability of PIN code leakage is further reduced.

The method for managing the rights of the user identification card provided by the embodiment of the present invention, when the input fingerprint information is matched with the fingerprint template, the PIN code corresponding to the fingerprint template is extracted by the correspondence between the fingerprint template and the PIN code, so that the user When the PIN code is enabled, only the fingerprint is required to be input, which reduces the probability of PIN code leakage, improves the security of the SIM card unlocking, and is convenient to use, thereby avoiding the situation that the user forgets the PIN code and causes the SIM card to be locked, thereby improving The availability of SIM card unlocking. In order to further reduce the probability of the PIN code leakage, the step of pre-establishing the correspondence between the fingerprint template and the PIN code is further provided. The embodiment of the present invention provides a method for managing the rights of the user identification card. The method is different from the previous embodiment in that, as shown in FIG. 5, the step 201, that is, the correspondence between the fingerprint template and the PIN code is established in advance, and may specifically include steps 501 to 505.

Step 501: Generate a fingerprint template according to the fingerprint information collected for the first time. The specific implementation method of the step 501 is the same as the step 301 shown in FIG. 3, and details are not described herein again.

In the step 502, the fingerprint template is mapped to the code. The specific implementation method of the step 502 is the same as the step 402 shown in FIG. 4, and details are not described herein again. Step 503: Set a new PIN code according to the encoding.

In this embodiment, the setting the personal identification code according to the encoding includes: the new PIN code is part or all of the encoding. When the code obtained by the fingerprint template mapping in the step 502 is a 4-digit code, all the codes are taken as a new PIN code; when the number of coded bits is more than 4 bits, random or according to a certain Rules (eg, truncating the last four digits, the first four digits, four consecutive digits, etc.) extract the four digits in the encoding as the new PIN code. The user's input is not required, which simplifies the steps of setting the PIN code.

Step 504: The new PIN code is replaced with the original PIN code and stored in the SIM card. The specific implementation of the step 504 is the same as the step 303 shown in FIG. 3, and details are not described herein again. In addition, in step 504, when there is no default PIN code in the SIM, the set new PIN code may be directly saved in the user identification card as the PIN code of the SIM without performing the replacement operation. At this time, since there is no default PIN code in the SIM card, the PIN code generated by the algorithm by the encoding is directly used as the set new PIN code.

Step 505: Establish a correspondence between the fingerprint template and the new PIN code. The specific implementation of the step 505 is the same as the step 304 shown in FIG. 3, and details are not described herein again.

In this embodiment, the PTN code is set according to the input of the user and the encoding, and the set PTN code is not known by the user. In the above step 206, when the interface for inputting the PIN code is popped up to prompt for the PIN code, the user cannot unlock the S top card by directly PIN code because the PIN code is unknown, and only by inputting the fingerprint, inputting the fingerprint and entering Step 202 above. Therefore, the number of times the user inputs the PIN code is reduced, and the probability of PIN code leakage is further reduced.

The method for managing the rights of the user identification card provided by the embodiment of the present invention, when the input fingerprint information matches the fingerprint template, the PIN code corresponding to the fingerprint template is extracted by the correspondence between the fingerprint template and the PIN code, so that the user When the PIN code is enabled, only the fingerprint is required to be input, which reduces the probability of PIN code leakage, improves the security of the SIM card unlocking, and is convenient to use, thereby avoiding the situation that the user forgets the PIN code and causes the SIM card to be locked, thereby improving The availability of SIM card unlocking.
