Integrating and detecting visual data security token in displayed data via graphics processing circuitry using a frame buffer

A method, comprising:

• establishing a video connection between an apparatus and a first device, the first device associated with a user;
• in response to establishing the video connection, transmitting a token to a second device equipped with a display, the second device also associated with the user, the token being displayed on the display of the second device;
• receiving visual data comprising the token displayed on the display of the second device, the visual data being generated by the first device, that includes a camera, capturing the token displayed on the display of the second device;
• accessing a frame buffer of a graphics processing unit (GPU);
• detecting the token in the frame buffer of the GPU, by analyzing a frame representing a section of the visual data;
• and
• in response to the token being detected in the visual data, generating an authentication to authenticate the video connection between the apparatus and the first device.

A non-transitory computer-readable storage medium for storing computer-readable instructions that, when executed by a computer, cause the computer to perform a method, the method comprising:

• establishing a video connection between an apparatus and a first device, the first device associated with a user;
• in response to establishing the video connection, transmitting a token to a second device equipped with a display, the second device also associated with the user, the token being displayed on the display of the second device;
• receiving visual data comprising the token displayed on the display of the second device, the visual data being generated by the first device, that includes a camera, capturing the token displayed on the display of the second device;
• accessing a frame buffer of a graphics processing unit (GPU);
• detecting the token in the frame buffer of the GPU, by analyzing a frame representing a section of the visual data;
• and
• in response to the token being detected in the visual data, generating an authentication to authenticate the video connection between the apparatus and the first device.
