Dredging and blocking combined privacy protection method and system

Abstract

The invention discloses a dredging and blocking combined privacy protection method and system. The method comprises steps as follows: 1) an application is scanned, all permissions of the application are listed, and whether the installed application is involved with a sensitive permission is judged; 2) as for the application involved with the sensitive permission, a user is reminded to use a cheat function strategy or a jump function strategy; the cheat function strategy specifically comprises steps as follows: the sensitive permission involved by an application program is hooked, a cheating function is implanted in the hooked function, and when the sensitive permission of application access is monitored, a false value is returned for the application; the jump function strategy specifically comprises steps as follows: a permission involved with a malicious application is extracted, and calling of the malicious application permission is bypassed by modifying an entry address of a permission function; 3) according to the strategy selected by a user, when the sensitive permission applies data, the false value is returned to the sensitive permission or permission calling is directly jumped. The security problems of privacy disclosure, permission abuse and the like of an existing application of a mobile phone can be effectively solved.
