  • Patent number: 11593349
    Abstract: A method, a system, and a computer program product for execution master data substitution. One or more first data objects in a master data storage are determined for replacement. One or more second data objects are identified for replacing the first data objects for storage in the master data storage. Replacement of the first data objects with the second data objects is performed in accordance with one or more data object requirements. Replacement of the first data objects by the second data objects is executed in accordance with the one or more data object requirements. A resulting replacement data set is generated and stored.

  • Patent number: 7376968
    Abstract: A system and method for facilitating BIOS integrated encryption is provided. An interface is defined between the operating system and the BIOS. The operating system employs this interface to provide BIOS code information to facilitate decryption of data that is encrypted on the system. In the pre-operating system boot phase, the BIOS employs the decryption information provided from this interface in order to decrypt the data. The decrypted information can be employed to facilitate secure rebooting of a computer system from hibernate mode and/or secure access to device(s).

  • Patent number: 7280956
    Abstract: An encrypted file system (EFS) and an underlying file transfer protocol to permit a client to encrypt, decrypt, and transfer file(s) resident on a server are disclosed. A user at a client computer can open, read, and write to encrypted files, including header information associated with encrypted files, and can add users to or remove users from an encrypted file.

  • Publication number: 20060179309
    Abstract: Systems and methods for managing multiple keys for file encryption and decryption may provide an encrypted list of previously used keys. The list itself may be encrypted using a current key. To decrypt files that are encrypted in one or more of the previous keys, the list can be decrypted, and the appropriate previous key can be retrieved. To re-key files, an automated process can decrypt any files using previous keys and encrypt them using the current key. If a new current key is introduced, the prior current key can be used to decrypt the list of keys, the prior current key can be added to the list, and the list can be re-encrypted using the new current key.

  • Publication number: 20050114688
    Abstract: An operating system copies data from memory pages into a paging file on disk, in order to free up space in the memory. A mechanism is disclosed that causes the data to be encrypted as it is copied into the paging file, thereby protecting the paged data from unauthorized (or otherwise undesired) observation. The data that is stored in the paging file is encrypted with a session key, that is generated shortly after the machine on which the paging file exists is started. The session key, which is used both for encryption and decryption of the paging file data, is stored in volatile memory, so that the key is not persisted across boots of the machine. Since the key is not persisted across boots, old paging file data that was stored prior to the most recent boot cannot be recovered in clear text, thereby protecting the data from observation.
