SYSTEM AND METHOD FOR AUTHENTICATION OF INFORMATION DISPLAYED ON COMPUTER SCREEN Russian patent published in 2018 - IPC G06F21/16 G06F21/64 G06F3/14 H04N1/36 

FIELD: information technology.

SUBSTANCE: synchronization system of information displayed on a computer screen and at the information display module of a portable computing unit external to the computer, using an application in real time for authentication of the information displayed on the computer screen, is disclosed. The mentioned system comprises: a) a data processing module for receiving data from a user's computer, where the data contains a message intended for the user; performing analysis of the received data, during which the contained message, message parameters and information identifying the message are determined; transmitting information unambiguously identifying the mentioned message, together with the message parameters, to the data transformation module; and transmitting the task for the formation of protection elements to the protection element module; b) a data transformation module for generating an information message containing the information received from the data processing unit and transmitting the generated information message to the video stream module; c) a protection element module intended for determining protection elements, depending on the received information and at least one protection element mapping rule; transmitting information on at least one protection element to the information display module and the video stream module, and at least one mentioned rule to the video stream module; d) a video stream module intended for generating a video stream in which the received protection elements and the information message are combined, and transmitting the generated video stream to the application for broadcasting on the user's computer; e) an information display module intended for synchronous output of the protection elements from the output information in the video stream broadcasted on a computer screen, comprising the displayed information and protection elements.

EFFECT: limiting and reducing the possibility of substituting information displayed on the user's computer screen, which is achieved by synchronizing the mentioned information with information displayed on the external portable device in real time.
