AbstractIn the past several years there has been an explosive growth in digital imaging technology and applications. Digital images and video are now widely distributed on the Internet and via CD-ROM. One problem with a digital image is that an unlimited number of copies of an "original" can be easily distributed and/or forged. This presents problems if the image is copyrighted. The protection and enforcement of intellectual property rights has become an important issue in the "digital world." Many approaches are available for protecting digital images and video; traditional methods include encryption, authentication and time stamping. In this talk we describe algorithms for image authentication and forgery prevention known as digital watermarking. A digital watermark is a signal that is embedded in a digital image or video sequence that allows one to establish ownership, identify a buyer or provide some additional information about the digital content. In this talk we will review the current state of watermarking and describe some of the open research problems.
