Abstract

The concept presents an idea to embed data in an encrypted image by using an irreversible approach of data hiding or data hiding, aimed at secretly embedding a message into the data. Massage communication over internet facing problems like data security, copyright control, data size capacity, authentication etc. A new idea is to apply reversible data hiding algorithms on encrypted images by wishing to remove the embedded data before the image decryption. The aim of this dissertation is to create a secure data hiding technology. The data hiding and image encryption are done by using two different keys. That is encryption key and the data hiding key. So the receiver who has the data hiding key can retrieve the data embedded.
