In the present scenario, the world has been digitalized and the data security plays a key role in the data Communication through mobiles, internet etc., hence data or image encryption methods are essential to provide security. In this regard, there are various existing methods for image encryption in which original image is scrambled by using SCAN patterns that are generated by the SCAN methodology. But, the novelty of the proposed method lies in generating a carrier image with the help of Alpha-numeric keyword. Each alpha-numeric key consists of a unique 8-bit code that is created by a 4 out of 8 codes. The proposed method now generates encrypted image by hybridizing this newly generated carrier image with the original image. Hence, from the results, it is shown that the proposed method produces highly distorted encrypted image. Also, it provides the decryption method to get back the original image.
