Steganography implementation on android smartphone using the LSB (least significant bit) to MP3 and WAV audio

The rapid growth of science and technology in the telecommunications world can come up with new ways for some people bent on abusing for threatening information security as hackers, crackers, carder, phreaker and so on. If the information is on the wrong side will result in losses. Information that must be considered is the security of confidential information. Steganography is a method that can be used to hide a message by using digital media. Digital Steganography using digital media as the container vessel such as images, sounds, text, and video. Hidden secret data can also include images, audio, text, and video. In this final audio steganography implemented. One method that can be used in steganography is the Least Significant Bit (LSB). Steganography implementation will be accompanied by the application of cryptography in the form of encryption and decryption. This method works is messages that have been encrypted beforehand will be hidden evenly on each region in MP3 or WAV already divided, with modify / change the LSB of the media container with the bits of information to be hidden. In making the steganography application, the author uses the Java programming language eclipse, because the program is quite easy and can be run in the Android smartphone operating system.
