  • Patent number: 10318462
    Abstract: An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) glass security layer. A predetermined reference flux or interference pattern, respectively, is an expected flux or reflection pattern of EM emitted from the EM emitter, transmitted by the glass security layer, and received by the EM receiver. When the PCB is subject to an unauthorized access thereof the optical EM transmitted by glass security layer is altered. An optical monitoring device that monitors the flux or interference pattern of the optical EM received by the EM receiver detects a change in flux or interference pattern, in relation to the reference flux or reference interference pattern, respectively, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.

  • Patent number: 10318484
    Abstract: An illustrative embodiment for optimizing scans using a Bloom filter synopsis, defines metadata to encode distinct values in a range of values associated with a particular portion of a managed object in a database management system into a probabilistic data structure of a Bloom filter that stores an indicator, encoded in a fixed size bit map with one or more bits, indicating whether an element of the particular portion of the managed object is a member of a set of values summarized in the Bloom filter using a value of 1 or definitely not in the set using a value of 0. The Bloom filter is compressed to create a compressed Bloom filter. The Bloom filter is added to the metadata associated with the managed object and used when testing for values associated with predicates.

  • Patent number: 10318487
    Abstract: A method, system and computer program product for sharing resources among remote repositories. In a shared file system, a resource identifier and metadata are created for a resource, where the resource identifier is stored in a lock file in a shared volume accessible by the remote repositories. The lock file is then released in response to distributing the associated resource to the remote repositories. Alternatively, in a peer-to-peer system, a request is received to create, read, update or delete a resource stored in a content repository. A resource name, a resource version and/or a resource fingerprint are received in connection with the request to create, read, update or delete the resource in the content repository. A determination is then made as to whether the received resource name, resource version and/or resource fingerprint matches the respective resource name, resource version and/or resource fingerprint stored in a node graph for the resource.
