Sternography idea by modifiying ones place of RGB values in pixels to conceal cipher data

[keitharm]

So if we were using my special character mapping, the message "wdR" in base64 (d2RS) could be encoded in 3 pixels.

Let's say the pixels are:

(45, 234, 34)

(212, 210, 39)

(134, 16, 83)

We could remove the 5 from 45, 4 from 234, etc.

This would give us 9 values to play with and using my encoding (which requires 2 integers per base64 character), we can encrypt the message "wdR" in base64 into 3 pixels.

"wdR" in base64 is "d2RS" which when converted to ints using my character mapping becomes (29, 54, 18, 19)

This would make the new pixel values:

(42, 239, 35) (214, 211, 38) (131, 19, 83)

So the image would look slightly different, but now it has the secret text encoded into it.
