Patent ID: 8489686

Claim:
A method comprising: computing, using an out-of-band (OOB) processor of a computing device, a first hash value for data stored in one or more sectors of a data storage device at a first time, the OOB processor being capable of communicating with a remote server irrespective of an operational state of an in-band processor of the computing device; receiving, with the OOB processor, a request from the remote server to transmit a portion of the data stored in the one or more sectors of the data storage device at a second time, the second time being subsequent to the first time; computing, using the OOB processor, a second hash value for the data stored in the one or more sectors of the data storage device at the second time; and transmitting, with the OOB processor, the requested portion of the data to the remote server in response to the second hash value not matching the first hash value.
