Title: Digital Watermarking Technology.

Abstract

Digital watermarking technology is used for document security, ownership and copyright enforcement, product tracing and counterfeit deterrence, retail checkout and recycling. Usually a secret data carrying signal is embedded in a host, such as an image, video or audio such that it is imperceptible to a human, but can be recovered easily with a computer. Signal Rich Art is a recent advancement in the field, in which we embed the signal in visible artistic/texture patterns which are cognitively imperceptible.
