Do you need to send a password through the
mail? This page presents a stereoscopic picture generator. The
Java-driven application lets you type in a password, maximum 8
characters (A-Z). The app then generates a stereoscopic picture.
By focusing into the picture with your stereo vision, the password then stands
out in 3-D. In order to read this picture, a malicious third party would
actually have to open your mail, and focus in on the picture (rather than using
various technical means to "see through" envelopes). The Java app runs on
your computer, and the password is not transmitted to the PrivaFone server.
For added security, we recommend generating two stereographic images: the
first one (the decoy) goes on an outer sheet of paper facing the envelope, and
the real password goes on the inner sheet of paper, and is shielded by the outer
sheet from view. Or you might try printing a cookie recipe on the back.
Click "Demo" to start the program.
Then capture the image (using a program like SnagIt) and print it, either in color or B&W (color is easier to see).
