A Comparison Between Parallel and Segmentation Methods Used for Image Encryption-Decryption

Abstract

Preserving confidentiality, integrity and authenticity of images is becoming very important. There are so many different encryption techniques to protect images from unauthorized access. Matrix multiplication can be successfully used to encrypt-decrypt digital images. In this paper we made a comparison study between two image encryption techniques based on matrix multiplication namely, segmentation and parallel methods. KEYWORDS Digital image, encryption, decryption, segmentation, parallel processing, speedup, efficiency.
