Abstract: Techniques are disclosed for constructing web (or other networked) documents as parameterized forms of other networked documents. For example, a document may be represented as a collection of changes to be applied to a first document which is incorporated by reference in the second document. Instead of delivering the entire document over a slower network connecting the content server to the content browser, the document is delivered as a collection of changes to previously delivered documents that are much closer to the user's content browser. In an exemplary embodiment of the invention, special software is not necessarily required at the end user for reconstructing the second document from the set of base documents and the set of modifications to the base documents.

Abstract: A method and system to protect web applications from malicious attacks is described. A stateful means of distinguishing between valid (e.g., harmless) and invalid (e.g., harmful) accesses is provided. A request from a content browser for content from an application server is forwarded by a firewall to the application server if it includes a URL that was previously transmitted from the application server. The firewall performs a security evaluation of the request if the URL of the request was not previously transmitted from the application server.

Abstract: Described herein are a method and a system to control access to content accessible via a network. The method may include receiving a Uniform Resource Locator (URL) from a client machine and submitting a search request based upon the URL to a search engine. The method includes receiving a search result including associated URL data and comparing the associated URL data with reference data. Access may be selectively denied to the content based on the comparison.

Abstract: A method and system to provide search results via a network is described. The method may comprise receiving a search request from a user including search criteria, searching cached World Wide Web documents to obtain a web result based on the search criteria, and searching for an associated document to obtain a restricted result based on the search criteria. The associated document may be associated with the user (e.g., the user may mark or otherwise identify the document after viewing it) and access to the associated document may be restricted. The web result and the restricted result may be communicated to the user for viewing via a web browser. In an example embodiment, the user may be provided via a web interface with an option to search the World Wide Web or a database including associated documents.

Abstract: A simple, secure and easy-to-deploy method and system for authenticating credit and debit cardholders at the point-of-sale on a computer network (e.g. the Internet) is disclosed. Cardholders are authenticated using digital signatures on a sales draft, in a manner that does not necessarily require any changes in the transaction flow of the participating financial institutions.
