An image encryption model based on using Frei-Chen bases

With the recent advances in internet and multimedia technologies by which the exchange and the transmission of information became easy, encryption methods have been proposed to protect confidential and secure digital data from illegal access. In this paper, we propose a new image encryption model that uses the Frei-Chen bases. The projections of the Frei-Chen bases on the image are used to represent the encrypted image. The proposed model has been tested on a large number of images and is shown to be secure and effective.
