“…In a plain image, the correlation coefficient should be high. In an encrypted image, a smaller correlation coefficient indicates higher security [40]. Smaller correlation coefficients are produced from the confusion and diffusion methods.…”

With increasing dependence on communications over internet and networks, secure data transmission is coming under threat. One of the best solutions to ensure secure data transmissions is encryption. Multiple forms of data, such as text, audio, image, and video can be digitally transmitted, nowadays images being the most popular and old encryption techniques such as: AES,DES,RSA etc., show low security level when used for image encryption. This problem was resolved by using of chaos encryption which is an acceptable form of encryption for image data. The sensitivity to initial conditions and control parameters make chaos encryption suitable for image applications. This study discusses various chaos encryption techniques.

In today's competitive world, examinations are a means of assessing a person's potential. It is therefore important that such process be unbiased, but several cases have been encountered where candidates use proxies to write exams and score well. To deal with the same, generally we use multiple identity proofs to authenticate the candidate, which increases the privacy concern and expended on maintaining the extra data and keeping it secure. This paper introduces a novel authentication technique using bit plane-based encryption for fraud candidate detection during any stage of the selection process. Multiple visual cryptography-based method has been explored for its suitability. The effect of noise and differently chosen encryption scheme has also been observed. With the currently available infrastructure, it is quite easy to implement the proposed system for authentication of students and provide a level platform for competition.
