The use of digital images and video is growing on the Internet and on consumer devices. Digital images and video are easy to manipulate, but this ease of manipulation makes tampering with digital content possible. Examples of the misuse of digital content include violating copyrights of the content and tampering with important material such as contents of video surveillance. In this paper we present an algorithm that extracts a binary signature from an image. This approach can be used to search for possible copyright violations by finding images with signatures close to that of a given image. The experimental results show that the algorithm can be very effective in helping users to retrieve sets of almost identical images from large collections of images. The signature can also be used for tamper detection. We will show that the signatures we extract are immune to quantization errors that result from compression and decompression.

With the increase in the amount of digital content that consumers have to deal with, both broadcast content and home captured video and images, there is a real need for tools that help manage multimedia content. In this paper we will describe a system that we are building to manage digital content at home. The system is designed for managing both still images and collections of video, where video can be either video captured by the consumer or clips that are captured from TV broadcast.
