Separable Reversible Data Hiding In Image Using a Keyless Approach

Reversible data hiding is a process in which the original cover can be losslessly recovered after embedded data is extracted while protecting the image contents confidentiality. Earlier many research papers proposed reversible data hiding but all those techniques are dependent on keys. This paper presents an efficient approach to reversible data hiding where we use a keyless approach for image encryption. We follow standard RDH algorithms for hiding data in image before encryption and then encrypting the image with a keyless approach.
