Abstract

Steganography is a technique to hide text or messages that other people do not know the contents of the text or the secret message. Steganography technique is often used to avoid suspicion and to avoid other people desire to know the contents of the text or the secret message. Digital image is one of the most well-known media and the public by the author. Digital image acts as a medium or a text container you want to hide a secret message. Methods LSB (Least Significant Bit) that hides the bytes of text or message you want to hide into the last byte in the digital image. LSB method has the advantage of not changing the size and shape of the digital image by naked eye, text data or messages hidden can be restored without any change in size and shape

Abstract

The WAV file format that is widely used rough on various kinds of multimedia and gaming platforms. Ease of access and technological development with a variety of media to facilitate the exchange of information to various places. The data are important and need to be kept confidential secret for a wide range of security threats so that data can be intercepted and acknowledged by third parties during the shipping process. Of these problems led to the idea to create an application data security functions can secure the data using the RSA algorithm. The programming language is C # with Visual Studio software, the processed data is a sample each byte in WAV file, the header will be the same as that originally WAV files can be played even if the information has been withheld. RSA algorithm can be implemented into a programming language that WAV files can be processed and secured the data.
