Steganography is the art and science of secret communication, concealing the very existence of communication. Modern cover types can take many forms, such as text documents, audio tracks, digital images, and video sequences. There has been extensive research on steganography imaging in the previous decade because of its popularity on the internet. Today, video files are attracting much more attention. They are transmitted more and more frequently in websites such as Facebook and YouTube that impose a greater practical importance to video steganography.
Hidden Information is a method of hiding secret messages in a media cover in such a way that an intentional observer will not be aware of the existence of hidden messages. In such applications, various file formats are used as a cover object that contains sensitive data. The principle of steganography is to protect and secure vital data. Video Steganography is the technique of hiding some hidden message inside a video. The addition of this information to the video is not recognizable through the human eye since the modification of a pixel color is negligible. The performance of this method can be improved with the use of Neural Networks methods (such as Artificial Neural Networks adoption (ANN) and Neural Networks of Rear Propagation (BPNN)). In this proposed method, the Neural Neural propagation method was used to perform Steganography in a video file.
Steganography is a Greek word meaning "writing covered or hidden". The idea of steganography is thousands of years old. Greek soldiers used to pass a secret message that shaved the head of a slave, tattoo a message in his head when hair grows again, then the tattoo could not be seen. The receiver shaves the slave's head and receives the message of the tattoo. The invisible ink was also used during World War II. Watermarks and fingerprints are closely related to steganography. Data concealment can be used for secret transmission. Steganography is a technique for hiding secret information in digital images, audio and video to protect information from third parties. Different types of techniques are proposed and have already been put into practice. The ability of steganography is to hide private data by indistinct, hiding its existence in a non-secret carrier file. In this sense, steganography differs from cryptography, which involves creating the content of unreadable secret information, without preventing unintended viewers from learning about its existence.
