International Classification:

G06F 1516

US Classification:

709231, 709229, 709232, 709233, 709234, 709320, 709322, 713152, 713164, 700 94

Abstract:

A method and an apparatus for securely mixing and splitting multiple audio data streams and determining the order of processing the audio streams. A audio server and an audio device driver are in kernel space of a given computer system. In one embodiment, the computer system has a data flow checker and adjuster for checking the flow of data into data queues and a setup application for connecting the audio server and the audio device driver. The data flow checker and adjuster adjusts the flow of data by sending a message up or downstream instructing the up or downstream processes/devices to send more data or stop sending data depending on how full the data queues are.

US Classification:

707724, 707725, 707781

Abstract:

A computer-implemented method and system of building a user reputation database for use in a user location data system. The method and system receive user location information containing personally identifiable data of a user and user position data. The user position data may or may not represent one or more actual geographic positions of the user. The user location information is temporarily stored and analyzed to provide a spam score associated with the user position data indicative of whether the user position data represents the actual geographic positions of the user. Data indicative of the spam score is also provided to user reputation database to store a user reputation score associated with the user.

US Classification:

713189

Abstract:

A computer-implemented method and system of quarantining user location information receives from a user device user location information that includes personally identifiable user data and user position data associated with one or more geographic positions of the user. The user location information is temporarily stored in a quarantine data storage database for a predetermined quarantine time, during such time it can be used for various analyses. After the quarantine time, personally identifiable user data of the user location information is filtered out before the user position data is sent for long-term storage to a filtered data storage system.

International Classification:

G06F 15/173

US Classification:

709224, 3703952, 455 1, 713168

Abstract:

Systems and methods according to aspects of the invention verify requests for information over a network. Computing devices communicating over a network transmit numerous signals with various types of information including spatial information, temporal information, device-specific information, and transmission specific information. This information may be used to generate statistical records of valid request for information. Various combinations of these signals may be used to determine whether a request for information is a valid request based on the statistical records associated with the signals. Where a request for information has been verified, the system and method may provide the information. Where the request for information has not been verified, the system and method may deny the request for information. Thus the system and method may be used to prevent and block scraping and spamming attacks.

International Classification:

H04L 29/06

US Classification:

726 1, 726 2, 726 26, 726 27

Abstract:

A computer program product has a computer-readable storage medium having computer program instructions embodied therein for performing a method for implementing a privacy policy for a user. The method may include the user developing rules that determine whether another user (requester) can access information related to the user. The rules may be stored in a database coupled to a server and evaluated when a request is received from the requester to access the information. If a rule is satisfied by the requester, the server can return the information to the requester. The information can be returned at a level of granularity specified by the user in the satisfied rule. A privacy level can be set by the user to allow access to requesters based on the rules or to deny access to any requesters.

Abstract:

A system, method, and apparatus are provided for visualizing quotas on resources within a computing environment (e.g., a data center, a computing cluster) that includes multiple brokers, gateway servers, or other entities that control access to the resource(s). Through a visualization interface, an operator of a quota system can set, change, and/or delete quotas on resources and/or sub-resources for any number of clients or consumers of the resources. The visualization interface may also enable access to a log of changes to quotas and/or graphs or other displays of statuses of any selected quotas for any selected clients and resources/sub-resources.
