Securing Secret Information

The art of information concealment has become a crucial subject since information security has grown to be a primary concern in the online world. Using cryptography and steganography plays a significant role in secure data transfer. Steganography is a covert writing technique; the message is contained behind a cover medium. Cryptography encrypts messages to hide their contents. Two-dimensional bar codes called QR codes can store text strings. They can encode data both vertically and horizontally, encoding more information. By combining the ideas of cryptography, steganography, and QR codes, an innovative method for covert communication is proposed in this paper. Statistical and security analyses of the proposed method show that the proposed method provides better imperceptibility, security, and robustness.
