Abstract: This present patent of invention discloses a process and equipment to extract high-level multimedia information (e.g. image, sound, and video). More specifically, this present invention discloses a progressive process of disturbance of multimedia content designed to extract non-visible characteristics in the natural state of the content analyzed. The process and equipment are able to gather information extracted from various media classes to solve known problems such as multimedia content categorization, hidden message detection, content tampering detection, robust watermarking, and recognition of the originating means of the media (e.g. type of camera used in the capture process) among other uses.
