Patent ID: 7436965

Claim:
An out-of-band communication system comprising: an encrypted data path that is configured to convey encrypted data between an operating system and a peripheral device; an optical out-of-band channel that is physically distinct from the encrypted data path, wherein the optical out-of-band channel generates a pseudo-random symmetric key and transmits to a peripheral device, wherein the peripheral device may be wire-based or wireless; wherein the pseudo-random symmetric key is stored by two parties; a computing device having the operating system and the peripheral device store the pseudo-random symmetric key, wherein the pseudo-random symmetric key establishes secure communication with communication devices; the optical out-of-band channel extends between an optical transmitter and an optical receiver, the optical out-of-band channel is further configured to transmit the pseudo-random symmetric key information from the optical transmitter to the optical receiver or from the optical receiver to the optical transmitter a mounting portion optically obstructs light containing key information that is transmitted to locations other than the optical receiver, wherein this permits key information transfer from a distinct optical transmitter to the optical receiver, the optical receiver is a transducer that converts light into an electrically readable signal; the optical transmitter has a light source of bandwidth that is detectable by the optical receiver; and data transferred in a transmission protocol.
