Abstract
A cryptosystem incorporating multiple chaotic maps is proposed. Visual cryptography is necessary in today’s world to combat a large number of data thefts. Image encryption using chaotic maps is a common procedure, but it does not ensure absolute security. We use two maps in this paper, to curb the problem of security. The use of two chaotic maps has made the process of image encryption more secure. Image encryption is done using tent map, which is superimposed on another image encrypted using the logistic map. The encryption scheme has a greater keyspace because of two chaotic maps instead of one and thus has better security against statistical attacks.
