ABSTRACT
This chapter highlights some quality research efforts in watermarking and fingerprinting that address the challenges in the emerging area of multimedia protection. It focuses on describing an audio fingerprinting scheme, which enables the legacy content identification by comparing the extracted fingerprint with the set of fingerprints associated with metadata in the restored system. The scheme is the first trial that parametrically analyzes the molecular matching pursuit (MMP)-derived atoms and explores the most representable features in lower dimension to become the signal fingerprint. The chapter explains an effective digital watermark fingerprinting technique for a video file based on principal component analysis and wavelet for peer-to-peer networks. It provides a description of a spatio-temporal just noticeable distortion-based watermarking scheme. The chapter discusses the proposed fingerprinting scheme based on one of the variants of the Matching pursuit approach—MMP for the legacy content identification. The watermark bit string is embedded bit by bit in a set of regions of the original video frame.
