Steganography In Images+Mp3+Video+Audio Files
When hiding information inside images the LSB (Least Significant Byte) method is usally used.
To a computer an image file is simply a file that shows different colors and intensities of light on
different area of an image. The best type of image file to hide information inside of is a 24 Bit.
BMP (Bitmap) image. The reason being is this is the largest type of file and it normally is of the
highest quality.
when an image is of high quality and resoulation is a lot easier to hide and mask information
inside of. Although 24 Bit images are best for hiding information inside of due to their size some
people may choose to use 8 Bit BMP's or possibly another image format such as Gif, the reason
being is that of posting of large images on the internet may arouse suspicion. It is important to
remember that if you hide information inside of an image file and that file is converted to another
image format, it is most likely the hidden information inside will be lost.
