Exemplary data structures include web documents having one or more control commands embedded in the head with manifest code. Exemplary methods include operating web applications when the client is offline, caching web applications, executable code, web documents, security code, and/or remote files, allowing web application access of local files, and operating client/web applications.

Abstract: A recipient computer system may receive one or more electronic messages. The recipient computer system may send one, two, or more challenge messages to the sender of the electronic messages in determining whether to deliver the electronic message. The recipient computer system may accept or reject an electronic message based on the response, or lack of response, to the challenge messages. The recipient computer system may send two or more challenge messages at intervals. A sender computer system may record activity of the sender computer system for a recipient computer system to use in determining whether to deliver an electronic message. A sender computer system may provide a summary of that activity with an electronic message. A sender computer system may provide an authorization key for a recipient computer system to use in determining whether to deliver an electronic message. The authorization key may be generated by a third party.

Abstract: Systems and methods for sorting electronic messages using attributes of senders or of sender addresses. An electronic messaging server sorts electronic messages using attributes associated with the senders or sender addresses of the electronic messages. The sender addresses and associated attributes are stored in an accept list. A sorting module uses the accept list to sort the electronic messages into various folders. The sorting module can also access other data sources, such as a contact list, to assist in sorting the electronic messages. The attributes can be determined independently of the user or can be set directly by the user. The attributes can also identify a status of a sender such as whether the sender is authorized, unauthorized, or unconfirmed.

Abstract: A system may include an electronic messaging management application that may access contact information. The contact information may include information maintained by one or more system users. The electronic messaging management application may determine how to process an incoming electronic message using at least a portion of the contact information. The electronic messaging management application may determine whether to send a challenge-response message to a sender of an electronic message using at least a portion of the contact information.

Abstract: Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content.

Abstract: Systems and methods are disclosed for managing and protecting electronic content and applications. Applications, content, and/or users can be given credentials by one or more credentialing authorities upon satisfaction of a set of requirements. Rights management software/hardware is used to attach and detect these credentials, and to enforce rules that indicate how content and applications may be used if certain credentials are present or absent. In one embodiment an application may condition access to a piece of electronic content upon the content's possession of a credential from a first entity, while the content may condition access upon the application's possession of a credential from a second entity and/or the user's possession of a credential from a third entity. Use of credentials in this manner enables a wide variety of relatively complex and flexible control arrangements to be put in place and enforced with relatively simple rights management technology.

Abstract: The present invention provides for systems and methods for determining the likelihood that an intended recipient is currently available to communicate via at least one communication mechanism. A presence module monitors the computer usage activity of the intended recipient. The data relating to the computer usage activity of the intended recipient is stored in a database, and is later utilized by a processing module for determining the likelihood that the intended recipient is currently available to communicate via the at least one communication mechanism. The likelihood that the intended recipient is currently available to communicate via the at least one communication mechanism is displayed to at least one other user by an interface module. A communication module is configured to send a message to the intended recipient via the at least one communication mechanism.

Abstract: The present invention provides for methods and computer programs for filtering instant messages sent to a recipient. An initial instant message is received from a sender, intended for the recipient. Then, a reply message is sent to the sender requesting that the sender perform a verification process. The method monitors for an incoming response message from the sender, and when the incoming response message is received, the method determines whether the sender properly completed the verification process.

Abstract: Systems and methods for reducing the number of challenge messages that are sent in response to an incoming message in situations where the incoming message is likely not unsolicited. The systems and methods include evaluating the behavior of a sender with regard to one or more federated messaging services and determining if the sender is approved or unapproved. If the sender is approved, the incoming message is deliver to a recipient's inbox without issuing a challenge message. Unapproved senders are required to respond to a challenge message.

Abstract: The present invention provides for navigation systems for table data structures, and methods for facilitating the locating of information in a table data structure. To generate the navigation system, a sort criteria being used to organize the table data structure is identified. After identifying page delineations in the table data structure, data ranges of each page are identified based on the sort criteria corresponding to each page. The data ranges corresponding to each page are displayed on a graphical user interface to indicate to the user the content of each page.

Abstract: Systems and methods for allowing challenge messages to be sent directly to a recipient's inbox where normally the challenge message would be sent to a pending folder or deleted. Challenge messages sent between federated messaging services contain a federated token which can be identified, authenticated and validated to determine whether the challenge message should be sent to a recipient's inbox. The federated token can include an authentication portion and a validation portion. Authentication methods for the authentication portion can include, for example, checksums, salts, hashes and digital signatures. Once a federated token is authenticated by decrypting the authentication portion according to one or more of these authentication methods, the federated token is validated by determining the defined use-base and determining whether the receipt of the federated token satisfies the defined use.

Abstract: Systems and methods for updating a user's organizational information. A text application is provided including a parser module for analyzing text documents accessed by a user and creating or updating the user's organizational information depending on whether organizational information exists in the text document. The parser module may further identify the type of organizational information and communicate with an organizational information application to find the correct template for the organizational information. The organizational information is inserted into the selected templates and saved with the user's organizational information.
