A Survey of Reversible Data Hiding Methods in Dual Images

ABSTRACT

Security systems become the first consideration to prevent illegal access as interest of information security has increased recently. Information hiding is one of the methods for secret communication, where the existence of the secret data is hidden. The embedding capacity and visual quality are important issues to measure the performance. In this survey, reversible data hiding methods in dual images are described and comparisons of these techniques are provided in terms of embedding capacity and visual quality.

KEYWORDS:

• Data hiding
