    abstract = {Graphics Interchange Format (GIF) is a graphics format that is most often used for the purposes of
website design. The GIF has a bit more color combinations than JPEG but able to store graphics with
background transparent or in the form of a simple animation. Because of the ability possessed by the GIF that
is could make an animated GIF from any number of images, it is sometimes still considered to be good to use
when to want to download loads of sources in large sizes, then the GIF image can be shown in advance, so that,
users don’t feel strange when the load occurs. The GIF image has a specific format that has the color map
containing as many as 255 entries and entry consists of a number of images in the GIF animations or one image
if not an animation. Spread Spectrum method of treating the cover-image as both a noise (noise) or as an effort
to add artificial noise (pseudo noise) into the cover image. On a method of steganography with Least Significant
Bit (LSB) of the image to GIF images, basically, consist of a part of the image, so that, it can be applied with
LSB method inserts a message in the LSB of each byte of an image from the image. Both of these methods
certainly have advantages and disadvantages of each. One of the advantages of each method of spread spectrum
is on better security compared with the method of Least Significant Bit (LSB). While the algorithm of least
significant bit was to allow the message size in the embed dynamic depending on the size of the GIF image.
In addition, in terms of the calculation of the peak signal-to-noise ratio and speed of embed course will also
differ on the use of both methods.}
