Techniques for securing data access
Abstract:
Techniques for securing data access are presented. A user's data is encrypted on multiple servers throughout a network. Each portion of the encrypted data resides on a different server, and each portion represents a non-contiguous data selection from the user's original unencrypted data. Each portion encrypted using a master credential that is different from the user's logon credential. Also, each portion encrypted using a server identity for the server on which that portion resides. An order, which is used for assembling decrypted versions of the encrypted portions back into the user's data, is acquired via another and different principal-supplied credential.
