Abstract

The invention provides an access control method. The method is characterized in that through acquiring first characteristic information of a user and second characteristic information of an application platform, according to the first characteristic information and prestored first identification information, whether the user is a legal user is determined; according to the second characteristic information and prestored second identification information, whether the application platform is a trusted application platform is determined so that illegal user access is blocked; when the user is the legal user and the application platform is the trusted application platform, whether the user possesses executive power of applications to be operated is determined according to the first characteristic information of the user so that safety problem caused by illegal operation of an unauthorized user is avoided; when the user possesses the executive power of the applications be operated, information resources which form one-to-one correspondence with the applications to be operated are acquired; according to the information resources, the applications be operated is executed. Therefore, interferences among the plurality of applications to be operated which are executed simultaneously are reduced and normal operation of the applications be operated is guaranteed.
