Abstract

The security of digital images is concentrating much attention nowadays, and many image encryption algorithms have been proposed by different authors and researchers. In [1], an improvement over an algorithm for image encryption was proposed. This paper explains the result and analysis of the proposed algorithm in [1]. The paper also discusses about the analysis based on some performance factors. The paper is organized into different sections as follows. Section 1 contains a basic introduction to the image cryptography and hill cipher. Section 2 contains description of the proposed system. Section 3 contains performance analysis of the proposed system. Section 4 contains the conclusion of the work.
