Patent ID: 8135135

Claim:
One or more computer-readable storage media comprising computer-executable instructions for strengthening algorithmic protection of data on a computing device in preparation for a disaster at the computing device, the computer-executable instructions directed to steps comprising: comparing, to protected decryption keys stored in a location remote from the computing device, multiple protected decryption keys that are stored on the computing device, the multiple protected decryption keys being able to be decrypted into at least one decryption key that can be used to access algorithmically protected data on the computing device; copying, to the location remote from the computing device, if the comparing reveals that none of the multiple protected decryption keys are equivalent to any of the protected decryption keys stored in the location remote from the computing device, at least one of the multiple protected decryption keys and a corresponding key that can decrypt the copied at least one of the multiple protected decryption keys into the at least one decryption key; removing at least some of the multiple protected decryption keys from the computing device, such that the removing leaves at least one protected decryption key that can be decrypted into the at least one decryption key that can be used to access the algorithmically protected data on the computing device, and wherein the removing the at least some of the multiple protected decryption keys strengthens the algorithmic protection of data; and algorithmically protecting at least some data on the computing device such that an associated key required to algorithmically unprotect the data has not previously been used by the computing device to access the data.
