description Data authentication is another common application of digital data, hiding. The authenticity and integrity of protected data are obtained by hiding a fragile signal within them. The fragile signal is such that the hidden data is lost or altered as soon as the host data undergoes any modification: loss or alteration of the hidden data is ta.ken as an evidence that the host signal has been tampered with, whereas the recovery of the information contained within the data is used to demonstrate data authenticity. In this case, the hidden data can be seen as a kind of trap, since a forger is likely to modify it inadvertently, thus leaving a trace of its action (be it malicious or not). Of course, the need to not alter the quality of t,he host signal is a furt,her motivation behind the willingness to conceal carefully the mthenticating information.
