Reversible Data Hiding on Image Encryption with Index Boundary for Partial Confidential Documents

An efficient data hiding method is proposed in the smart cyber-attacks such as data theft, virus attacks on the transmitting of whole confidential data, partial confidential data via private and government networks. The transmitting data over the internet is one of the better solutions to make a work easy and fast even though protecting data from the smart hackers is vital role in the cyber-crimes. There are various protection techniques of confidential data like digital watermarking, digital signals with embedding data into images, audio and videos. The existing watermarking techniques using RSA is a time consuming process for number of iterations to be performed even in signal decryption of image. These complexities of iterations to be overcome by the Least Significant Bits, DWT transformation and Arnold transformation were failing in all aspects of security requirements. The proposed method of reversible data hiding has an efficient encryption in medical images, health care image and data transmitting in various organizations.
