Audio and Video Steganography -- This system is used to send the message in the unknown format. There are chances to miss the confidential or important information, when sent in the normal format. These problems can be avoided by making use of this system. The concept of Steganography will be very helpful to the management, whose prime requirement is to send confidential information in a secure manner. This software lets you embed important or private messages or files into uncompressed format files like .mp4, sound files or video files. There is no loss to the quality of the media files as it uses the least significant bits (LSB) of the file, which are not used by the media players or audio players. The sender hides the message in the media (audio or video) file and sends it to the receiver. The authorized receiver receives the media files and then retrieves the message using this software. So there is no way to find out the message embedded in the media. This mechanism is known as Steganography. Any color pixel is made up of a combination of RED-GREEN-BLUE (RGB) wherein each RGB component consists of 8 bits. If the characters in ASCII are to be represented within the color pixels, the rightmost digit called the LSB can be altered. Any variation in the value of this bit leads to minimal variation in color. If we want to hide the word ‘DIG’ in the media (audio or video), we take the LSB of every color and hide each bit of the word in its RGB combination. This is very secure. The message is encrypted first and then converted into bytes. This method uses double authentication, where the user must enter the encryption key as well as validation code to extract the secret message. The encryption key is the combination of how the encryption format should be. Think encryption keys as passwords to the real text. But they are not real passwords. For example, for each encryption key there will be different encryption format, you are actually mentioning the format and not passwords. Validation code is not actually a code, but the byte position from which hidden message begins in the media file. Apart from hiding the message, a detailed log file is created containing the following details. The name of the system from which this file was sent, the name of the audio or video file containing this secret message, the email-id of the sender and the receiver, the date of dispatch and the size of the source file and the output file. Thus this mechanism will be very useful to bury the information in a secure way without any loss of data. The confidential or important information, which sent with normal format, there might, may be a chance of happening misuse cases. These can be avoided by making use of this system. The mechanism, which is used to hide the message in the media files, is known as STEGANOGRAPHY. -- For More Details, Contact Us **************************** Arihant Techno Solutions, Mail us to Order this Project: arihantsinfo@gmail.com
