Abstract
An apparatus, method, and computer readable medium that include accessing a frame buffer of a GPU, analyzing, in the frame buffer of the GPU, a first frame of displayed data from a source, the source being an image or video-based feed including an object, identifying the object in the first frame from the source, the object associated with a first value of a parameter, analyzing, in the frame buffer of the GPU, a second frame of the displayed data from the source, identifying the object in the second frame from the source, the object associated with a second value of the parameter, determining an entropy of the object based on a difference between the first parameter value and the second parameter value, generating a random number based on the entropy of the object, and generating an encryption for encrypting data based on the generated random number.
