  • Patent number: 10726044
    Abstract: A system can serialize moves and mounts across namespaces based on lamport clocks. In some examples, the system obtains a request to move a content item from a source namespace to a destination namespace. The system processes an incoming move at the destination and an outgoing move at the source. The system processes for the content item a delete at the source and an add at the destination. The system assigns a first clock to the incoming move and a second clock to the outgoing move, the first clock being lower than the second clock. The system assigns a third clock to the delete and a fourth clock to the add, the third clock being higher than the second clock and lower than the fourth clock. The system serializes the incoming and outgoing moves, the delete and the add based on the first, second, third and fourth clocks.

  • Patent number: 10685399
    Abstract: Due diligence of mortgage documents is faster and simpler. An electronic mortgage application often contains or references a collection of many separate electronic mortgage documents. Electronic data representing an original version of an electronic mortgage document and its current version may be hashed to generate digital signatures. Any auditor may then quickly conduct the due diligence by comparing the digital signatures. If the digital signatures match, then the due diligence reveals that the electronic mortgage document has not changed since its creation. However, if the digital signatures do not match, then the electronic mortgage document has changed since its creation. The auditor may thus flag the electronic mortgage document for additional due diligence. Regardless, a result of the due diligence may be incorporated into one or more blockchains.

  • Patent number: 10671756
    Abstract: A method, system and computer program product for detecting sensitive personal information in a storage device. A block delta list containing a list of changed blocks in the storage device is processed. After identifying the changed blocks from the block delta list, a search is performed on those identified changed blocks for sensitive personal information using a character scanning technique. After identifying a changed block deemed to contain sensitive personal information, the changed block is translated from the block level to the file level using a hierarchical reverse mapping technique. By only analyzing the changed blocks to determine if they contain sensitive personal information, a lesser quantity of blocks needs to be processed in order to detect sensitive personal information in the storage device in near real-time. In this manner, sensitive personal information is detected in the storage device using fewer computing resources in a shorter amount of time.

  • Patent number: 10311234
    Abstract: According to an aspect of the present disclosure, a digital processing system, in response to identifying multiple files opened with write permission by a process, creates a corresponding backup copy of each of the opened files. The system computes a frequency of opening of the files with write permission by the process, and then determines whether the computed frequency is greater than a threshold. If the frequency is determined to be greater than the threshold, the system provides control to a user to recover any of the files (opened by the process) based on the corresponding backup copy (previously created in response to opening). Thus, the execution of a ransomware in the system may be potentially detected and the associated maladies (such as unavailability of personal data, requirement to make payment for recovering the personal data, etc.) may be avoided.

  • Patent number: 10282099
    Abstract: Intelligent snapshot tiering facilitates efficient management of snapshots and efficient restore of snapshots. For intelligent snapshot tiering, a storage appliance can limit cross-tier migration to invalidated data blocks of a snapshot instead of an entire snapshot. Based on a policy, a storage appliance can identify a snapshot to be migrated to another storage tier and then determine which data blocks are invalidated by an immediately succeeding snapshot. This would limit network bandwidth consumption to the invalidated data blocks and maintain the valid data blocks at the faster access storage tier since the more recent snapshots are more likely to be restored.

  • Patent number: 10146865
    Abstract: A directed graph and a semantic ontology are simultaneously employed to enable tagging of data. Tags from the directed graph contain special properties linking them to a semantic ontology such that activating a node on the graph, will provide specific actions relating to one or more ontologies. Humans or machine executable algorithms can use the directed graph as a classification system, which enables a decision making process to occur, one step at a time. Such an approach enables complex problems sets to be broken down into smaller directed graph processes. Each process can then be either automated using computer executed algorithms, manual using humans, or a combination of both. In this way an n-tiered workflow system can be developed that enables large scale asynchronous and distributed tagging.

  • Patent number: 10146466
    Abstract: A technique for managing metadata in a data storage system designates block pointers as either sources or copies, where sources contribute to reference counts of pointed-to structures but copies do not. The technique maintains parent-child relationships between parent BPSs (block pointer sets) and child BPSs, where each BPS includes an array of block pointers. Each child BPS is created as a copy of a parent BPS and has block pointers initially designated as copies. The technique performs a metadata-merge operation to merge the block pointers of the parent BPS into those of a child BPS by promoting attributes of block pointers in the child BPS from copy to source, avoiding any need to perform reference count updates on structures pointed to by promoted block pointers.

  • Patent number: 10135924
    Abstract: Techniques are provided for computing data and metadata layout prior to storage in a storage system using a processing platform. An exemplary processing platform comprises one or more of a compute node and a burst buffer appliance. The processing platform communicates with a plurality of the compute nodes over a network, wherein a plurality of applications executing on the plurality of compute nodes generate a plurality of data objects; computes erasure metadata for one or more of the data objects on at least one of the compute nodes; and provides the erasure metadata with the corresponding one or more data objects to a storage system. The processing platform optionally determines a full set of the data objects to be stored and queries the storage system to determine an anticipated layout of the full set of the data objects to be stored. The anticipated layout allows special handling, for example, for small files and large files that are identified based on predefined criteria.

  • Patent number: 10089032
    Abstract: A technique for managing storage in a data storage system sends a write from a second file system to a first file system at block-level granularity of the first file system and provides a set of flags that identify which flash-page-size portion(s) of a block are being changed. If the write is directed to a data block that is not shared, such that no write split is required, the improved technique checks the set of flags and proceeds to overwrite the data block in the first file system with only the flash-page-size portion(s) that have changed. The improved technique thus performs the overwrite in flash-page-size increments, avoiding writes to flash pages that remain unchanged.
