Steganografi can be performed on the BMP file, especially with the use of the attribute value of pixels, with the number of pixels is large enough then the RGB values are also provided large enough and the capacity of the file will also be proportional to the number of pixels the same. The value of this attribute proved to affect the amount of files that can be accommodated and the quality of the file is still good enough when a file has been inserted. Capacity of data that can be accommodated in the BMP file, influenced by the number of pixels that are available on the file (the value of the resolution on file), and the large size of the file file. BMP file quality stenography results are influenced by the file size of resolution file (if the image has a resolution of the pixels that are available are also quite large) and size of files to be inserted, the smaller the value the greater the resolution or file size to be inserted then the worse the quality of The resulting file.
Making these applications using the software Microsoft Visual Basic 6
