Various embodiments provide methods and systems for controlling an access to applications on a mobile terminal. In an exemplary method, an opened application can be scanned and an application identification can be obtained. The application identification can be compared with a pre-stored target application identification. When the application identification is compared to be consistent with the pre-stored target application identification, an unlock interface can be displayed. An unlock command can be obtained to run the application on the mobile terminal. An exemplary system for controlling an access to an application on a mobile terminal can include a scanning module, a comparing module, a displaying module, and an executing module.
