Keyboard 鈥渟niffing鈥� software installed by hackers can grab your Internet logins and passwords. So how do you establish your identity over the Internet without typing anything into your PC? Use a kind of ID based on cellphone tones, says Encotone of Jerusalem (WO 01/45054).
Mobile phones can generate secure personal ID codes by combining and encrypting the handset鈥檚 unique 鈥淚MEI鈥� number with the SIM card鈥檚 number. Encotone鈥檚 cellphone converts this secure code into audible tones that you play into a PC鈥檚 microphone. The PC then reconstructs the ID code from these warbles and sends it over the Internet.
