International Classification:

H04L 9/32

US Classification:

726 19, 726 17

Abstract:

An arrangement is provided for programmatically responding to a privilege request on behalf of a user by pre-configuring a trusted entity with a list of processes requiring elevated user credentials and a set of user's credentials having such privilege. The trusted entity determines if a requested process is included in the list of processes, and responds to the privilege requests generated by the kernel of the operating system for such processes, eliminating the need for the user to manually authenticate using some type of input mechanism.

US Classification:

707705, 707E17014, 707E17017

Abstract:

The ranking quality of a ranked list may be evaluated. In an example embodiment, a method is implemented by a system to access log data, ascertain which entries of a ranked list are skipped, and determine a ranking quality metric from the skipped entries. More specifically, log data that reflects user interactions with a ranked list having multiple entries is accessed. The user interactions include at least indications of which of the multiple entries are selected entries. It is ascertained which entries of the multiple entries of the ranked list are skipped entries based on the selected entries. The ranking quality metric for the ranked list is determined responsive to the skipped entries.

US Classification:

707769, 707E17014

Abstract:

Systems, methods, and computer media for efficiently processing user log data are provided. A received user log data analysis request specifies: target user log features that identify users in a target user group, analysis user log features that identify data associated with the users in the target user group, and an analysis to perform on the identified data associated with the users in the target user group. Occurrences of specified features are extracted from user logs and stored. Users associated with an occurrence of each of the extracted and stored target user log features are identified as users in the target user group. Occurrences of the analysis user log features that are associated with a user in the target user group are extracted and reformatted for the analysis specified in the analysis request.

International Classification:

G06Q 10/10

Abstract:

A method for responding to a consent request for an action based on a set of records is described. The method includes receiving the consent request, including a set of identifiers and the action for obtaining consent; locating a first record of a first object type and a second record of a second data type, wherein the first record corresponds to a first identifier in the set of identifiers, the second record corresponds to a second identifier of the set of identifiers, and one or more of the first and second records includes consent information for performing the action; determining a final response based on the first and second records, wherein the final response includes at least one proceed element that indicates whether consent exists for the action based on at least the first and second records; and returning the final response as a response.

International Classification:

G06F 17/30
G06F 21/62

Abstract:

At least one database table of denormalized values corresponding to selected values of field properties in records across multiple disparate tables of the database environment is maintained. A structured query is received through a structured query language application program interface (API). The structured query to request a listing of records across the multiple disparate tables of the database environment. The database table is searched for indications corresponding to records across the multiple disparate tables of the database environment corresponding to the selected values indicating communication with a specified party. A listing of records from across the multiple disparate tables that satisfy the selected values is returned through the structured query language API.

Abstract:

In various embodiments, methods and systems for implementing distributed data object management are provided. The distributed data object management system includes a distributed storage system having a local metadata-consensus information store in and one or more remote metadata-consensus information stores. A metadata-consensus information store is configured to store metadata-consensus information. The metadata-consensus information corresponds to erasure coded fragments of a data object and instruct on how to manage the erasure coded fragments. The distributed storage system further includes a local data store and one or more remote data stores for the erasure coded fragments. The distributed data object management system includes a distributed data object manager for operations including, interface operations, configuration operations, write operations, read operations, delete operations, garbage collection operations and failure recovery operations. The distributed data object management system is operates based on metadata paths and data paths, operating in parallel, for write operations and read operations.

Abstract:

In various embodiments, methods and systems for implementing distributed data object management are provided. The distributed data object management system includes a local metadata-consensus information store and one or more remote metadata-consensus information stores for metadata-consensus information and a local data store and one or more remote data stores for erasure coded fragments. For a write operation, corresponding metadata writes and data writes are performed in parallel using a metadata write path and a data write path, respectively, when writing to the local metadata-consensus information store and the one or more remote metadata-consensus information stores and the local data store and the one or more remote data stores. And, for a read operation, corresponding metadata reads and data reads are performed in parallel using a metadata read path and a data read path, respectively, when reading from the metadata-consensus information stores and the data stores.
