Loading a Bitmap and Generating noise

Author : V.Girish

Environment: Compiled using VC7.0 and tested using Win 2000

This demo loads a bitmap and generates "Noise" which makes the bitmap unviewable.
The bitmap can still be opened in MS-Paintbrush or other utilities , but it would be just
random dots plastered everywhere and no information can be deciphered from it

1) Click the Load Bitmap button to load a bitmap file .

2) Click the Generate Noise button to generate the noise image.
:::))Note that the Noise image will overwrite your original bitmap.

3) To get the original bitmap back, Click the Revert button.
:::))That will overwrite the noise image and save the actual bitmap back to hard disk.

Thats it. All Luck folks.

NOTE 1 : I've added just a little testing here.
Test every operation carefully before you actually ship it .

NOTE 2 : This should give you an idea how to generate noise.
Be aware that this can be broken easily even by novice crackers.
Use any proven encryption technique in the Process function
of the source code to generate the noise image
