Performance Analysis of Biometric Image Encryption in Transformed Formats using Public
M. Gobi, R. Sridevi · 2015
Due to the prompted growth of multimedia applications, the preservation of multimedia data becomes very important. The security of multimedia images can be achieved through Cryptography. This type of image encryption requires more attention towards its implementation. There are many different cryptographic techniques used for image encryption. Elliptic Curves Cryptography is believed to provide high security with smaller key sizes, which is very useful in many applications. This paper proposes the transformation of images into Base64 and Binary formats before image encryption. The transformed image is encrypted using Elliptic Curve Cryptography algorithm and encrypted image is stored in the database in a safe manner for future references. Based on the experiments done, Base64 transformation performs better than Binary transformation.
