A reliable hybrid cryptosystem for colour image encryption.

In recent years, more information has been transferred in electronic form, so the science of cryptography got more attraction. Cryptography is an efficient and effective procedure to ensure that our data is accessed only by the intended receiver. Also, it makes sure that the data is not adulterated. In this paper, we have proposed hybrid cryptography for colour images which could provide a reliable resistance against differential security attacks. We have observed that the use of the blowfish algorithm and chaos logistic maps could ensure improved image security and performance, providing stable results in most conditions.
