Embodiment 1

[0037] Such as figure 1 As shown, a personal information protection method provided by an embodiment of the present invention is applied to a mobile terminal including a secure element, and the method includes:

[0038] S101. Acquire a password input by a user when a protected object of the mobile terminal is accessed.

[0039] Specifically, the protected object is an encrypted file stored in the storage space of the mobile terminal in the form of ciphertext. When the user accesses the protected object, the mobile terminal prompts the user to enter a password as the decryption password for accessing the protected object through the man-machine interface. The password entered by the user includes but is not limited to any of the following: first, the user enters the corresponding symbol on the interface as the password; second, the user's biometric information is collected through the sensor of the mobile terminal, and the key feature information of the biometric information is...

Embodiment 2

[0048] Such as figure 2 As shown, a personal information protection method provided by a preferred embodiment of the present invention includes:

[0049] S201. The mobile terminal receives a protection object and a password preset by a user.

[0050]Specifically, when the personal information protection function is enabled on the mobile terminal, the user can perform a preset password in a preset operation directory. The protection object may be preset when the mobile terminal leaves the factory, or may be an object to be protected that is freely identified and selected by the user after leaving the factory. The way to preset the password can be any of the following: first, the user enters the corresponding symbol on the interface as the encrypted password; second, collects the user's biometric information through the sensor of the mobile terminal, and extracts the key feature information of the biometric information as the encrypted password The third is that the sensor of...

Embodiment 3

[0064] Such as image 3 As shown, a personal information protection system provided by a preferred embodiment of the present invention includes an access control device 10 and a security device 20, wherein:

[0065] The access control device 10 is used for obtaining the password input by the user when the protected object of the mobile terminal is accessed; and controlling whether to allow access to the protected object according to whether the security device decrypts successfully;

[0066] The security device 20 is arranged on the security element, and includes an object decryption module 203 for decrypting the protected object according to the password input by the user.

[0067] As a preferred solution, the security device 20 also includes a reference signature information establishment module 201 and an object encryption module 202, wherein:

[0068] The reference signature information establishment module 201 is used to receive the user's preset protection object and pa...

Abstract

The invention discloses a mobile terminal and a method and system for protecting individual information of the mobile terminal, and belongs to the field of mobile terminals. The method comprises the steps: when a protected object of the mobile terminal is visited, obtaining a password input by a user; decrypting the projected object through a safety element according to the password input by the user; controlling whether the protected object is allowed to be visited through whether decryption is successful or not. By the adoption of the method and system for protecting the individual information of the mobile terminal, SE of the mobile payment terminal is applied to protection of the individual user information, the characteristics that the SE is a CPU encryption machine with high safety are fully utilized for encrypting and decrypting the individual information, and malicious software can be prevented from obtaining the individual information; when the terminal is lost or stolen, the protected object cannot be leaked due to the fact that the projected object is encrypted, and therefore the safety of the individual user information can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobile terminal which applies SE (Secure Element, secure element) to the security of personal information and its personal information protection method and system. Background technique [0002] With the intelligentization of mobile terminals and the development of the mobile Internet, mobile terminals have gradually become an indispensable tool in people's lives, and the security of users' personal information has increasingly become the focus of attention. On the one hand, mobile terminals store and link to institutional networks related to personal information. Various software can quickly access personal terminals and obtain personal information. Personal information is at risk of leakage at any time. On the other hand, when the mobile terminal is lost or stolen, since the stored information is stored in the mobile storage space in plain text, personal ...
