An Enhanced and Robust Steganography and Cryptography Method Using an Embedding Algorithm
摘要
The two widely used techniques for safe data transfer and concealing are steganography and cryptography. Information was employed by the approaches to either conceal or cipher its existence. Steganography is the art and science of thrashing announcement; a stenographic system incorporates encoded information in the unremarkable cover media in order not to raise the suspicion of an eavesdropper. Cryptography is the awareness that employs mathematics to protect and retrieve data; the information is transformed keen on a number of added gibberish form. The enhanced LSB information concealing algorithm of data by means of the RSA cryptographic algorithm is the main subject of this article. Data hiding and cryptography are combined, and the safety of information hiding is increased by enhancing the visual characteristics visible to the human eye and the encryption technique. At last, we have an encryption method that outperforms the LSB algorithm in terms of embedding capacity and PSNR. As a result, the two methods usually work together to greatly increase security.
