SYSTEM AND METHOD FOR BLOCKING ACCESS TO PROTECTED APPLICATIONS Russian patent published in 2017 - IPC G06F21/60 G06F21/52 G06F21/84 

FIELD: information technology.

SUBSTANCE: method for blocking access to a user-displayed information is disclosed, according to which: a. the coefficient of confidentiality elements of the graphical interface processes are launched on a computing device is calculated by monitoring activity; b. intercepting by intercepting means the process access to the information displayed to the user for determining at least: information on the process accessing the information displayed to the user, wherein said information includes at least a process identifier (PID); areas on the display of the computing device on which the information is displayed to the user and accessed by the process, wherein determining area on display of the computing device is at least determining location of area on display of the computing device; c. analysing by intersection analysis means which is determined at the stage of the previous area on the computing device display with areas of elements of the graphical interface of processes executing on the computing device to determine which of the areas of the elements of the graphical interface of said processes: contain said area; are contained in said area; partially intersect with said area; d. calculating by intersection analysis means of the importance of the previously determined area on the display of the computing device based which of the areas of graphical interface elements of processes executed on the computing device contain said area, are contained in said area, and which of the areas of the graphical interface elements of the processes partially intersect with said area; e. calculating by security means of the access danger rating to the information displayed to the user based on information in the process accessing the information displayed to the user; f. calculating by security means combination with the combination of the access security rating to the information displayed to the user and the importance rating of the area; g. blocking by interception means which has been intercepted in step "b" to the information displayed to the user if the combination of the access danger rating to the displayed information and the importance rating of the area calculated in the step and to which access is made exceeds the threshold value.

EFFECT: increased the security of the user computing device which is achieved by blocking the access of the process to the information displayed to the user.
