摘要

Abstractȁ4; Recently, numerous novel algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency. This paper discusses and compares the two methodologies. Some similarities and differences are presented, in addition to discussing some of the best known algorithms for each. Lastly, an idea for a possible algorithm which combines the use of both steganography and visual cryptography is suggested. There are several ways of hiding data in files of different formats, leaving various signs of hidden data. Can data hidden in an original image be detected after it undergoes visual cryptography? Would that be a scenario which computer forensic investigators and forensic software developers have to account for?
