  • Patent number: 10402571
    Abstract: Technologies for de-duplicating encrypted content include fragmenting a file into blocks on a computing device, encrypting each block, and storing each encrypted block on a content data server with associated keyed hashes and member identifications. The computing device additionally transmits each encrypted block with an associated member encryption key and member identification to a key server. As part of the de-duplication process, the content data server stores only one copy of the encrypted data for a particular associated keyed hash, and the key server similarly associates a single member encryption key with the keyed hash. To retrieve the file, the computing device receives the encrypted blocks with their associated keyed hashes and member identifications from the content data server and receives the corresponding member decryption key from the key server. The computing device decrypts each block using the member decryption keys and combines to blocks to generate the file.

  • Patent number: 10303466
    Abstract: A technology is described for embedding a semantic annotation in operation code. An example method may include creating an executable package file that includes operation code obtained from a source executable package file. The operation code may be analyzed to identify a program element included in the operation code that is associated with a semantic annotation. The semantic annotation may then be inserted into the operation code relative to the program element associated with the semantic annotation. The executable package file may be executed, launching a program, and the semantic annotation may be evaluated during execution of the program to retrieve semantic context obtained from the ontological data referenced by the semantic annotation. The semantic context may be processed, causing execution behavior of the program to be analyzed in relation to the program element included in the operation code.

  • Patent number: 10261791
    Abstract: Systems, methods, and computer-readable media are disclosed for executing a predicted load that bypasses memory access for a load instruction. A first physical register that is predicted as storing a value to be loaded by the load instruction is identified and the value stored in the first physical register is copied to a second physical register for use by a consumer operation. A predicted store instruction corresponding to the load instruction is identified and a mapping table is accessed to obtain data associated with the predicted store instruction. The data is evaluated to determine whether the predicted load meets dependency constraints. As a result of execution of the predicted load, the consumer operation can utilize the data stored in the first physical register directly and bypass the cache memory access that would otherwise be required to execute the load instruction.

  • Patent number: 10248353
    Abstract: A method for dynamically freeing storage space in a tiered storage system includes reading attribute values associated with data sets residing on a first storage tier. The method compares characteristics of the data sets to the attribute values to determine which initial data sets qualify to be moved from the first storage tier to a second storage tier. The method further determines whether movement of the initial data sets creates a desired amount of free space on the first storage tier. In the event the movement does not create the desired amount of free space, the method modifies the attribute values, determines which additional data sets qualify to be moved from the first storage tier to the second storage tier, and recalculates the amount of free space that would be generated. A corresponding system and computer program product are also disclosed.
