Virtual Watermarking for Color images
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 3
Abstract
This work proposes a virtual watermarking technique for colored images. In the proposed work, sender uses two images one is cover image and other is secret image. Let us consider the secret image to be embedded as sub image and the cover image as master image. The master image is chosen such that it iscommon to both sender and receiver such as Lena image which is used in most of the image processing projects. In the first phase of the project an index array is derived by applying virtual watermarking process on bothmaster and sub image. Once the index array is obtained, the same is encrypted using an encryption key. The encrypted index array along with the encryption key is sent to the receiver. In the second phase, the receiver side decrypts the index array using the key. Once the index array is obtained reverse virtual watermarking is applied on index array and common master image. At the end of this process the original sub image is obtained back. The main advantage of this technique is that master image is not transmitted, hence providing more protection against image processing attacks
