Abstract
An encryption method for an image, alphanumeric message, random pattern, or any other visual depiction is disclosed. Furthermore, a device for decoding the concealed message created in accordance with the aforementioned method is disclosed. The method and device rely on the limited range of light wavelengths which trigger phosphorescence in a given material. Those wavelengths can be combined with others to obscure the activating light pattern when viewed by the human eye.
Claims11
A method for hiding a message comprising:
- obtaining a message to be hidden;
- the message being in a visible form which is composed of pixels;
- converting all pixels to the same subpixel color channel, while varying the intensity level of each pixel such that the message is preserved;
- obtaining a second image which will be used to obscure the first, also being in a visible form, composed of pixels;
- ensuring that the pixels of the second image contain no amount of the subpixel color used for the first image, but are entirely composed of colors from yet-unused subpixel channels;
- and
- combining the first set of pixels with the second set of pixels such that the intensity levels from the first set of pixels are included in the corresponding pixels of the second set.

A method for revealing hidden images comprising:
- loading a specially prepared image which contains a hidden message obscured by a second image onto a screen comprised of a multitude of pixels each containing a plurality of subpixels;
- obtaining a decoding device with a planar surface coated with a material which is activated only by the hidden message, and pressing this surface against the screen while the specially prepared image is displayed on this screen;
- and
- separating the decoding device from the screen such that the activated regions of the decoding device material may be seen.
