Techniques for Data Hiding
Data hiding, a form of steganography, embeds data into digital media for the purpose of identification, annotation, and copyright. Seve constraints affect this process: the quantity of data to be hidden, the need for invariance of the data under conditions where a “host” signal is subject to distortions, e.g., lossy compression and the degree to which the data must be imm to interception, modification, or removal by a t party. We explore both traditional and novel techniques for addressing the data-hiding proc and evaluate these techniques in light of three applications: copyright protection, tamper-proofing, and augmentation data embedding.
