SISTEM STEGANOGRAFI DENGAN METODE LEAST SIGNIFICANT BIT (LSB) TERACAK

Abstract

Information security has become important today. Steganography is one of the ways to
make any information secure. It hides information by inserting it in a media or cover. LSB (Least
Significant Bit)steganographic technique has become popular because of its simplicity. LSB
(Least Significant Bit) is one algorithm from steganography. The weakness of LSB is bits of
embedded are inserted sequentially. It can be easily tracked. Our research using text as embedded
message and WAV audio format as cover-object. We combine LSB and LCG (Linear Congruetial
Generator) to determinant the random position of replacement bit. Outcome of this research is a
software that was develop by waterfall model and coded in Visual Basic. The result shows that
embedded message can be encode dan decode
