Abstract

Data piracy, illegal access, and data loss have all become major concerns in recent years when it comes to safe data exchange. Hackers can easily intercept and manipulate data if it is not transmitted correctly. As a result, data security has become a key research topic. The use of cryptography and steganography together has been shown to be advantageous. Cryptography is the science of encrypting data, whereas steganography is the art of hiding text inside any multimedia file. The goal of this work is to provide a novel method for hiding information in a video, by combining cryptography and steganography. To protect against any cyber-attack, the message is first encrypted using the AES technique, where the key is hashed using SHA-2, followed by a modification of the LSB method by including a key to make the hiding process non-sequential, in terms of robustness and security.
