Abstract: A method for presenting a plurality of application programs for use in a device, includes: acquiring, for each of the plurality of application programs, at least two parameter factors indicating application information about the application program within a set time period; determining, for each of the plurality of application programs, a sorting factor based on the at least two parameter factors acquired for the application program; and sorting the plurality of application programs according to the sorting factors of the application programs, respectively, and presenting the sorted application programs.

Abstract: A mobile device security system can include circuitry configured to receive first user-interaction information associated with the mobile device. The first user-interaction information can be indicative of first sensed interactions of a user with the mobile device during a first period of time. The system can also include circuitry configured to receive second user-interaction information associated with the mobile device. The second user-interaction information can be indicative of second sensed interactions of a user with the mobile device during a second period of time that is subsequent to the first period of time. The system can also include circuitry configured to compare the first and second user-interaction information. The system can also include circuitry configured to report anomaly information to a security service of the mobile device and/or a remote system, where a difference between the first and second user-interaction information exceeds a threshold.
