WavestoreUSA Image Authentication process employs digital signature

The aim of the Wavestore Image Authentication process is to be able to prove that an image or set of images were originally recorded on a particular Wavestore digital video recorder and that they have not been manipulated in any way. This mechanism also allows detection of images that have been modified after the initial recording. Authentication is only possible on recorded images and there is about a 4 second delay before recorded images can be verified.

The core method for achieving image authentication is a digital signature. However, applying a digital signature to every recorded image would be very computationally expensive. For example, recording 800 images per second is quite achievable on Wavestore, but if each image were to be digitally signed most modern CPUs would not be able to keep up. For this reason, a slightly more complex scheme is used to achieve the end goal.
