here is the cleaned up version folks. looks like my old macbook is developing some quirks. *** well, just for shits and grins (pardon my language folks), while I was up at the colorado center for the blind, I proposed an idea of encrypted braille. the idea was so nasty that the braille instructor got a migraine from even thinking about it! :) The idea was to invert the state of each dot. this is a simple substitution type of encryption. another good substitution type would be using a matrix with a known code word and the matrix itself (consisting of a horizontal line of numbers and letters in sequence, and a vertical line on the left side also of in sequence you would use a code word at the top and then point to each letter on the H and V and then go to the letter or number it indicates in the matrix. Mind you, this is a pen/paper type of encrypting that would be hard to break unless you know the code word and know the table layout. Then you can get real crazy by assigning number values to each braille cell (such as A = 1000000, b = 120000 and so on). This would allow you to add a second layer of encryption. THis may be a bit extravagant when it comes to keeping your passwords safe and usable by you, but it certainly would frustrate someone seeking to breach your machine with physical access. -eric _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
