Patent ID: 8670566

Claim:
A method of securely transmitting data between a computing device and a peripheral device using a recovered encryption key, the method comprising: pairing the computing device and the peripheral device over a wireless connection; placing a first of two devices into an additional security operational mode, the two devices comprising the computing device and the peripheral device; triggering transmission of a command from the first of the two devices to a second of the two devices over the wireless connection to cause the second of the two devices to enter the additional security operational mode, or receiving a command transmitted from the second of the two devices over the wireless connection at the first of the two devices before placing the first of the two devices into the additional security operational mode; generating an encryption key at the peripheral device; at the peripheral device, converting the encryption key into a shorter alphanumeric string from which the encryption key is recoverable and outputting the shorter alphanumeric string, wherein the shorter alphanumeric string into which the encryption key was converted is printed to paper by the same peripheral device that generated the encryption key, provided in audio format, or presented on a Braille pad; the computing device receiving, from a user interface provided by the computing device, the shorter alphanumeric string; recovering the encryption key at the computing device from the shorter alphanumeric string received from the user interface provided by the computing device; and transmitting data encrypted with the encryption key over the wireless connection between the computing device and the same peripheral device that generated the encryption key, the wireless connection established in accordance with a wireless protocol.
