digital watermarking
(I) Computing techniques for inseparably embedding unobtrusive
marks or labels as bits in digital data--text, graphics, images,
video, or audio--and for detecting or extracting the marks later.
(C) The set of embedded bits (the digital watermark) is sometimes
hidden, usually imperceptible, and always intended to be
unobtrusive. Depending on the particular technique that is used,
digital watermarking can assist in proving ownership, controlling
duplication, tracing distribution, ensuring data integrity, and
performing other functions to protect intellectual property
rights. [ACM]
