20090141902 | APPARATUS AND METHOD FOR SECURING DATA IN COMPUTER STORAGE - Apparatus, and an associated method, for maintaining data, such as a data file, in secure form. Security keys are stored and maintained at a central location. The security key is downloaded to a device that is to operate upon the data. When the security key is authorized to be downloaded to a computer device, a time boundary is associated with the security key. The time boundary defines the period of usability of the security key. The security key is used at the computer device to encrypt the data each time the data is written to storage and to decrypt the data each time the data is read from storage. Thereby, at all times, when the data is stored at storage, the data is maintained in secure form. | 2009-06-04 |
