RGB Color Image Encryption-Decryption Using Gray Image


Ahmad A.M Sharadqah

This paper presents a novel effective method for image encryption, which employs obtaining a gray image from the original image, then encrypting this image. The novelty of this method lies in deploying the concept of matrix multiplication for encryption-decryption purpose. The effectiveness of the proposed encryption method lies in minimizing encryption-decryption times and minimizing the mean square error between the original and the decrypted images. In recent years, encryption technology has been developed quickly and many image encryption methods have been used to protect confidential image data from unauthorized access. The proposed method has high security features because the matrix key used for encryption-decryption is generated randomly and makes the process of hacking the matrix key very difficult.

Keywords: Direct conversion, Inverse conversion, HSI model, RGB model, Encryption, Decryption, Matrix key, Encryption time, Decryption time, MSE.
