Wireless authorization mechanism for mobile devices and data thereon

摘要

In a bi-directional embodiment, an authorization transponder 114 coupled to the mobile device 128 transmits an interrogating message, which includes a UID 116 associated with the mobile device, to a nearby wireless key 100. The wireless key compares this received UID 116 with the one or more UID's 102 stored on the wireless key, and if a match is detected, sends the wireless key's UID or encrypted variant thereof to the interrogating authorization transponder 114. On receiving the UID from the wireless key 100 and determining that it matches the authorization transponder UID 116, a command is sent from authorization transponder 114 to mobile device 128 enabling some or all operations of mobile device 128. In a uni-directional embodiment, one or more UID 102 are periodically transmitted from a wireless key 200 to a receiver 122 in authorization receiver 202 coupled to the mobile device 128 to be controlled, wherein the UID 102 from the wireless key 200 is compared to a UID 116 associated with the authorization receiver 202. On receiving the one or more UID 102 from the wireless key 200 and determining that it matches the authorization receiver UID 116, a command is sent from authorization receiver 202 to mobile device 128 enabling some or all operations of mobile device 128. Yet another embodiment of the invention controls access to data on a passive mobile device, such as that data stored on the magnetic stripe of a transaction card 306, by authorizing the card reader 304 to read additional card data when the UID on the card matches a UID of a nearby wireless key. Upon reading a UID from the card, the card reader interrogates a wireless key for its UID, and compares these two UID's. If the two UID's match, authorization for further data transfer from and to the card is given.

主权项

1. A system for controlling operation of a mobile device and/or access to data on the mobile device, comprising:
an authorization transponder coupled to said mobile device, having a unique identification (UID), a transmitter for wirelessly transmitting said UID to a nearby device, a receiver able to receive a UID wirelessly transmitted from said nearby device, and a controller able to compare the authorization transponder UID with the UID transmitted by the nearby device, such that if a match is determined, operation of all or a subset of functions of said mobile device is enabled; and said nearby device, having a unique identification (UID), a receiver able to receive said UID from said authorization transponder, a controller able to compare the UID of said nearby device with the UID received from the authorization transponder, and a transmitter which transmits the UID of said nearby device to said authorization transponder if the UIDs match, said nearby device being a passive transponder, generating power for its operation from the received radio frequency energy transmitted by said authorization transponder coupled to the mobile device.
