Enhanced Image Security Using Stenography and Cryptography

In this age of information technology, the most vital part of information and communication exchange is the Internet. With advances in information technology and the Internet, digital media has become one of the best-known tools for data transfer, but this is still facing many challenges, including issues of authentication, modification, ad copyright protection. Many techniques such as encryption, authentication, and steganography can be used to protect these digital data. To secure information, encryption and information hiding are used widely. In the proposed work, a combination of encryption and information hiding is used to provide additional security, which means that it provides two-layer protection. The security level of the hidden image is measured in the term of PSNR and MSE parameters. In stenography, low MSE value and high PSNR value are better. The proposing work improves the result of previous work in the term of PSNR and MSE. To make the image security more robust and more secure, also add the cryptographic process with steganography.
