A proposed model for text and image encryption using different ‎techniques

Abstract

Data security and protection is one of the most common technologies used in the field of computer ‎ science. This is because of its great importance in all fields related to daily life, whether political, ‎ economic, and other aspects change. In this research paper, a new intelligent system ‎ that ‎ concentrates on image ‎ and text encryption and decryption is proposed. ‎ Furthermore, ‎ the image recognition rate is increased. In this paper, ‎ the Rivest Shamir Adleman 3 key (RSA3k) algorithm is used but ‎ in a new ‎ technique to encrypt and decrypt ‎ text. The proposed technique relies on using square root ‎ of public ‎ key as ‎ private key. XOR ‎ operation for colored images ‎ encryption and decryption is ‎ performed. By calculating signal to noise ratio (PSNR), mean square error (MSE), and bit error ‎ rate (BER), the most important things that we address how to provide data security ‎ for large data based on encryption techniques and increase the security of multimedia data and texture date and ‎ address the problem of time and accuracy in image matching. ‎ the results show that the quality of images after decryption is good.
