In one embodiment a method for probabilistically quantifying a degree of relevance between two or more citationally or contextually related data objects, such as patent documents, non-patent documents, web pages, personal and corporate contacts information, product information, consumer to behavior, technical or scientific information, address information, and the like is provided. In another embodiment a method for visualizing and displaying relevance between two or more citationally or contextually related data objects is provided. In another embodiment a search input/output interface that utilizes an iterative self-organizing mapping technique to automatically generate a visual map of relevant patents and/or other related documents desired to be explored, searched or analyzed is provided. In another embodiment, a search input/output interface that displays and/or communicates search input criteria and corresponding search results in a way that facilitates intuitive understanding and visualization of the logical relationships between two or more related concepts being searched is provided.

In a system for providing access control management to electronic data, techniques to secure the electronic data and keep the electronic data secured at all times are disclosed. According to one embodiment, a secured file or secured document includes two parts: an attachment, referred to as a header, and an encrypted document or data portion. The header includes security information that points to or includes the access rules and a file key. The access rules facilitate restrictive access to the secured document and essentially determine who/when/how/where the secured document can be accessed. The file key is used to encrypt/decrypt the encrypted data portion. Only those who have the proper access privileges are permitted to retrieve the file key to encrypt/decrypt the encrypted data portion.

Secured data format for access control

A system and method for smart, persistent cache management of received content within a terminal. Received content is tagged with cache directive allowing cache control to determine which of cache storage locations to use for storage of content. Cache control detects the number of instances that received content correlates to a newer version of purged content and provides the ability to re-classify cache persistence directive based upon the number of instances.

Embodiments disclosed herein provide a control device and a method executing thereon for allocating network bandwidth to users accessing a controlled network. In response to a user connecting to the control device using a user device, the control device obtains a user bandwidth allocation profile for that user based on user credentials. The user bandwidth allocation profile may be stored local or remote to the control device. A provisioning module running on the control device can map attributes in the user bandwidth allocation profile to a traffic control rule and associate the traffic control rule with the user based on the user credentials and considering information identifying the user device used by the user to connect to the control device. A traffic conditioning module running on the control device can regulate the network bandwidth usage by the user utilizing the traffic control rule associated with the user.

System and method for dynamic bandwidth provisioning

To grant or deny access rights to a user attempting to access a protected system or secured electronic data, an access right evaluation process is carried out among all applicable policies including those embedded in the secured electronic data. In a preferred embodiment, the access right evaluation process is invoked only when a system being accessed is protected or a file being accessed is detected to be in a secured format. Further, the access right evaluation process is configured preferably to operate transparently to the user. The access right evaluation may be advantageously used in systems or applications in which devices, mediums or electronic data are secured and can be restrictively accessed by those who are authenticated and have proper access privilege.

Dynamic evaluation of access rights

A streaming media caching mechanism and cache manager efficiently establish and maintain the contents of a streaming media cache for use in serving streaming media requests from cache rather than from an original data source when appropriate. The cost of caching is incurred only when the benefits of caching are likely to be experienced. The caching mechanism and cache manager evaluate the request count for each requested URL to determine whether the URL represents a cache candidate, and further analyze the URL request rate to determine whether the content associated with the URL will be cached. In an embodiment, the streaming media cache is maintained with a predetermined amount of reserve capacity rather than being filled to capacity whenever possible.

A distributed policy model for access control is disclosed. In an enterprise-only mode, each node within a networking environment has its resource access governed by the same enterprise-wide policy. The enterprise-wide policy is set through creation of one or more enterprise policy objects. In an integrated mode, nodes are organized in a number of arrays. Each array has an array-wide policy set through creation of an array policy object. Each array-wide policy initially inherits the enterprise-wide policy. Additional resource access and protocol use restrictions can be added to the individual array-wide policies. In an array-only mode, each array has an array-wide policy also set through creation of an array policy object, but the policy does not necessarily initially inherit an enterprise-wide policy. In a stand-alone mode, a single server has its own policy.

Distributed Policy Model For Access Control

The impact of placing an ad on a web page may be tested before the ad is deployed on the web page In one example, an entity submits the ad to be tested to a portal, and the ad is stored A test manager then schedules tests of the ads on test machines The ad may be tested by having the test machines retrieve the web page on which the ad is to be tested If an ad is delivered with the page, that ad may be replaced with the test ad and also with a null ad that is designed to have little or no impact on the page Performance metrics may be measured for the page with the test ad, and also for the page with the null ad The delta between the performance metrics of the page with the test ad and the page with the null ad constitutes the impact of the ad on the page
