The present invention is a method for improving delivery of content to a client communicating with a server on the Web. Groups or clusters of clients are formed by processing the IP addresses of the clients according to a network-aware, radix-encoded trie classification process. The groups of clients are categorized based on information about one or more clients in each group that can be determined by the server. That information is used to help drive tailored actions on the part of Web servers. Users with poor connectivity may choose not to spend much time at a Web site if it takes a long time to receive a page, even if the Web server at the site is not the bottleneck. Retaining such clients may be of interest to a Web site. Better-connected clients may be able to receive enhanced representations of Web pages such as with higher quality images.

A method and an apparatus for providing privacy in a network are disclosed. For example, the method receives a request, e. g. , an HTTP request, from a user for information, wherein the information includes at least a Uniform Resource Locator (URL) of at least an aggregator. The method identifies all personally identifiable information of the user. The method then masks the personally identifiable information from the browser in the endpoint device of the user, while responding to the request.

The present invention is a method for improving delivery of content to a client communicating with a server on the Web. The client is categorized based on information about the client that can be determined by the server. That information is used to help drive tailored actions on the part of Web servers. Users with poor connectivity may choose not to spend much time at a Web site if it takes a long time to receive a page, even if the Web server at the site is not the bottleneck. Retaining such clients may be of interest to a Web site. Better-connected clients may be able to receive enhanced representations of Web pages such as with higher quality images. Once a client is characterized as poor, a variety of server actions can be taken by the server, including altering the manner in which content is delivered, including guiding server policy decisions, aiding in caching decisions or deciding when to redirect the client to a mirror site. The method may also use network-aware client clustering techniques to provide client categorization. Such a cluster categorization can then be used to categorize subsequent clients from that cluster, even if a client-specific categorization is not available.

A proxy cache maintains a copy of multiple resources from various servers in a network. When the proxy cache must generate a validation request for at least one resource at one of the servers, the proxy cache piggybacks one or more additional cache validation requests related to documents presently stored in the cache but originating from or associated with the server in question. Upon receipt of an indication of the freshness or validity of the cached copy of the document, the proxy cache can then make a determination as to whether to request an update of the document.

In accordance with an exemplary embodiment of the present invention, a method is provided that includes maintaining a plurality of identification bits associated with a user and a minimum personal privacy level identifying if any of the plurality of identification bits are authorized for disclosure, and receiving a request for one or more identification bits of the plurality of identification bits. The method also includes determining whether the identification bits of the request exceed the minimum personal privacy level, and if the identification bits of the request exceed the minimum personal privacy level, identifying to the user the identification bits of the request that exceed the minimum personal privacy level. A computer-readable recording medium having stored thereon computer-executable instructions is provided, and an exemplary system is provided.

A method for providing network access privacy by classifying filter parameters of a group of users who are accessing one or more network destinations. The system includes a means for collecting information from both users, and about network destinations, generating suggestions for a user regarding filter parameters, and filtering network communications of users going to network destinations. In operation, users who are accessing network destinations are prompted to choose from a selection of filter parameters. The information provided by these users is then analyzed and used to generate suggested filter parameters for other users. As users provide more information to the system about various network destinations the system is able to provide more information to users about more network destinations and thus generate more accurate filter parameter suggestions. After a user selects their filter parameters the system filters a range of information coming from the user and going out to the network destination.

Secondary leakage of private information is identified and remedied. Internet activity of a first party can result in such secondary leakage of private information of a second party. Information about the second party that would not otherwise be known becomes public based simply on related information that has been placed on a public site of a third party by the first party. Such disclosure is detected and the victim may be notified about the location. The victim can then decide if such secondary leakage is acceptable. If not, the first party or the third party may be notified, the activity may be stopped and the offending information can be removed.
