Title: SYSTEM OF SECURE CLIENT SIDE DATA STORAGE
Abstract:
A method of long-term securing and reuse of locally accessible data at a second location remote from a first location; said method comprising issuing a request from the second location to the first location to receive a data batch; the data batch encrypted at the second location to form an encrypted data batch; the encrypted data batch having associated therewith a decryption key for recovery of the data batch from the encrypted data batch; calculating an identity characteriser of the data comprising the encrypted data batch; storing the key and the identity characteriser at the first location; transmitting the data batch to the second location for immediate use at the second location; transmitting the encrypted data batch to the second location for storage at the second location for subsequent reuse of the data batch at the second location; deleting the data batch after use at the second location; in the event of need to reuse the data batch at the second location sending a request to the first location for the key for decryption of the encrypted data batch; the key being sent from the first location to the second location for decryption of the encrypted data batch subject to a proving condition.
