摘要： Various approaches are described for auditing integrity of stored data. In one approach, a data set is provided from a client to a storage provider, and the data set is stored at a first storage arrangement by the storage provider. An auditor determines whether the data set stored at the first storage arrangement is corrupt without reliance on any part of the data set and any derivative of any part of the data set stored by the client. While the auditor is determining whether the data set stored at the first storage arrangement is corrupt, the auditor is prevented from being exposed to information specified by the data set. The auditor outputs data indicative of data corruption in response to determining that the data set stored at the first storage arrangement is corrupt.

摘要： One embodiment relates to a computer-implemented method for role discovery in access control systems. User accounts are selected according to a predetermined algorithm. For each selected user account, a new role is created covering a set of permissions including all permissions which the user account needs but is not yet covered by another role that the user account has. The new role is given to the user account so that all permissions needed by the user account are covered. Any additional user accounts which still need the set of permissions covered by the new role are also found, and the new role is given to these additional user accounts, if any. Other features, aspects and embodiments are also disclosed.

摘要： Various approaches for extracting client's data from a storage provider are presented. In one approach, an auditor is initialized with a verification data set that confirms that an initial version of a data set stored by the storage provider is intact. The auditor extracts a second version of the data set from the storage provider; the second version hides information specified by the data set from the auditor. The auditor determines whether the second version matches the initial version. The second version is returned to the client if the initial version matches the second version. The auditor is prevented from recovering the information specified by the data set using the state information, and the client need not store any state information related to the initial and second versions needed to recover the information specified by the data set. If the initial version does not match the second version, the auditor outputs data indicative of data corruption.

摘要： A transactional memory system uses a volatile memory as primary storage for transactions. Data is selectively stored in a non-volatile memory to impart durability to the transactional memory system to allow the transactional memory system to be restored to a consistent state in the event of data loss to the volatile memory.

摘要： Computer-implemented systems and associated operating methods implement a fast join for databases which is adapted for usage with flash storage. A system comprises a processor that performs a join of two tables stored in a storage in pages processed in a column orientation wherein column values for all rows on a page are co-located in mini-pages within the page. The processor reduces input/output operations of the join by accessing only join columns and mini-pages containing join results.

摘要： A distributed balanced tree having a plurality of nodes distributed across a plurality of servers is accessed. Version information associated with a node of the distributed balanced tree is retrieved. Validity of a lookup transaction performed on the balanced tree is determined by verifying a version value of only the leaf node accessed during the lookup operation against the retrieved version information.

摘要： A transactional shared memory system has a plurality of discrete application nodes; a plurality of discrete memory nodes; a network interconnecting the application nodes and the memory nodes, and a controller for directing transactions in a distributed system utilizing the shared memory. The memory nodes collectively provide an address space of shared memory that is provided to the application nodes via the network. The controller has instructions to transfer a batched transaction instruction set from an application node to at least one memory node. This instruction set includes one or more write, compare and read instruction subsets, and/or combinations thereof. At least one subset has a valid non null memory node identifier and memory address range. The memory node identifier may be indicated by the memory address range. The controller controls the memory node responsive to receipt of the batched transaction instruction set, to safeguard the associated memory address range during execution of the transaction instruction set. The batched transaction instruction set is collectively executed atomically. A notification instruction set may also be used to establish a notification, triggered upon a subsequent write event upon at least a portion of a specified address range.
