Abstract

The invention provides an information protection method and device. The method comprises the steps that false contact person information is generated; the trusted levels of all applications are set, the applications are at least classified to be the trusted applications and the non-trusted applications, and the authority of accessing the false contact person information is given to the non-trusted applications; whether the applications which request to access the contact person information are the non-trusted applications or not is judged; if yes, the false contact person information is provided for the non-trusted applications. The information protection device comprises a generation module, a setting module and a processing module. According to the information protection method and device, the false contact person information is provided for the non-trusted applications, the effects of confusing the public and lulling opponents are achieved, no chance of breaking is given to the opponents, and the absolute safety of privacy-sensitive information is guaranteed. The false contact person information generated by the method and device can be repeatedly used, compared with an existing encryption scheme, the system overhead is lowered to a great extent, and the maintaining problem of keys is solved.

Description

technical field

[0001] The present invention relates to the technical field of information security, in particular to an information protection method and device. Background technique

[0002] Existing terminals use rights management to control access rights to contacts and short messages, or encrypt the content of contacts and short messages.

[0003] Some third-party software often requires users to provide access permissions for contacts and text messages. Failure to provide corresponding permissions will affect the user's application experience or even limit the user's use. Although the method of encrypting contacts and short messages will increase the difficulty for others to obtain private information, there are several problems: first, there is no encryption algorithm that cannot be cracked, and once private information is leaked, it is still unsafe; second, Encryption algorithms that are more difficult to crack often require terminal configuration support with highe...
