Abstract
A system may include an imaging system coupled to a host subsystem. The imaging system may include an image sensor that provides image frames to the host subsystem. The image sensor may include a data authentication subsystem that appends corresponding authentication data to each of the image frames. Each set of authentication data may be generated based on a subset of the image frame data (e.g., corresponding to image data generated by pixels defined by a sparse region-of-interest within the pixel array). The host subsystem may securely provide region-of-interest parameters to the image sensor to update the sparse region-of-interest in an adaptive manner to account for factors such as computational load of the host subsystem and authentication coverage for the entire pixel array.
