The need to avoid suspicion in a potential observer/investigator, though it can be seen as a weak requirement for the protection of transmitted data, it can be extremely useful. For example, once discovered that the data has been protected by means of certain security tools, a malicious user that is strongly interested in such data could make a great effort in trying to remove the protection, for example, by cracking the password or by exploiting the vulnerabilities of the algorithm that was used to protect the data. Hence, to transfer information in a secure way, it is sometimes better to hide it inside other data, rather than protecting it in a conventional manner. One of the most important techniques in data hiding is steganography.
