Abstract

In today's world of advanced and fast growing network, each and every type of digital information is communicated via internet. The demand of the time is the implementation of an effective, sensitive and less time consuming encryption system that can be secured from unauthorized access. Typical encryption systems have played marvelous role for the systematic working of modern day cryptography as it is necessary to encrypt the digital image before their transmission over the network. So, an enhanced approach is proposed for Image Compression by Discrete Cosine Transform (DCT), Encryption and Decryption by Pixel Shuffling and Steganography by double image hiding to affirm the increased security of the previous approach.
