Disclosed are systems and methods for blocking access to protected applications. An exemplary method includes: intercepting access by a process of first information to be displayed on the user's device; determining second information based on the interception of the access by the process, the second information associated with the process; determining a region on a display of the user's device associated with the first information; analyzing one or more intersections between the region and at least one graphic interface associated with the process; and blocking the access by the process to the first information based on the analysis of the one or more intersections between the region and the at least one graphic interface associated with the process.
