This book proposes a new technique for the verification of authenticity of transmitted images through the Internet The rapid growth of the Internet and digitized content made image, video and audio distribution simpler. Hence the need for image data protection is on the rise. In this paper, we propose a secure and computationally feasible image, video and audio encryption/decryption algorithm based on DNA sequences. The main purpose of this algorithm is to reduce the big image encryption time. This algorithm is implemented by using the natural DNA sequences as main keys. The first part is the...
