Publication number: 20100031349Abstract: A secure storage system includes a storage device having a communication device and a memory. The communication device is for polling a communication medium. A security token is received from the communication medium via the communication device of the storage device. The security token received from the communication medium is compared to a second security token stored on the storage device. In one embodiment, a current location of the storage device is determined. The current location of the storage device is compared to an approved security zone. Access to the memory is provided if the security token received from the communication medium matches the second security token stored on the storage device and the current location of the storage device lies within the approved security zone. A time-out counter is set to a non-zero value after access to the memory is provided.Type: ApplicationFiled: July 29, 2008Publication date: February 4, 2010Applicant: WHITE ELECTRONIC DESIGNS CORPORATIONInventor: Gregory C. Bingham
