Image encryption: Using AES, feature extraction and random no. generation

During data transmission, data can be transmitted in the form of text, image, audio and video, hence securing all kinds of data is most essential in today's era. Securing Image data is one of the major concern and a complex term. Various visual cryptographic techniques have been developed for confidentiality, authenticity and integrity of images during transmission and when it is received at other end. This paper proposes an Image encryption technique on the basis of 128-bit AES, Feature extraction and random no. generation. Applying AES in two levels and generating key on the basis of feature extraction makes the system more confidential and secure against cryptanalysis attacks.
