Abstract
A digital content object comprised of plural portions is steganographically encoded, with different portions of the object conveying different steganographic data. Data steganographically conveyed in a first portion can be required to access information in a second portion. Data steganographically conveyed in the second portion can be required to access information in a third portion, and so on. Such arrangements make it more difficult for hackers to gain access to electronic content.
