A solution for managing a set of collaborative contacts is provided. Each collaborative contact includes one or more collaboration capabilities, each of which corresponds to a unique collaboration tool (e.g., voice over IP, instant messaging, email, and/or the like). Identifying text can be used to search the set of collaborative contacts and obtain a set of candidate contacts. An availability status for each collaboration capability of each candidate contact can be requested and a display can be generated that includes the set of candidate contacts. In one embodiment, the display can include an indication of the collaboration capabilities for one or more of the candidate contacts, and/or the availability status for one or more collaboration capabilities. A user can use the display to request a collaboration session between the user and one or more of the candidate contacts.

Verifiable authentication credentials are provided to foreign systems without passing an id and password to the protected resource. A user wishing to access a secure remote site is prompted for credentials, the credentials are authenticated locally and a digitally signed token is created. The token is redirected to the secure remote site by the user's browser using HTTP redirection. The digital signature is verified by the secure remote site preferably by a digital signature web service. The remote site establishes communications with the user if the digital signature is valid.

Authenticating and communicating verifiable authorization between disparate network domains

Embodiments of the present invention address deficiencies of the art in respect to search engines and provide a novel and non-obvious method, system and computer program product for a variable density query engine. In an embodiment of the invention, a search engine data processing system can be provided. The system can include a content index, and a variable density search engine coupled to the content index. The variable density search engine can include program code enabled to vary a density of entries in a result set according to a varying size of the result set. In this regard, in one aspect of the embodiment, the density can range from a title for each entry in the result set to a full textual description for each entry in the result set to an audiovisual element for each entry in the result set.

Variable density query engine

A system and method of performing cooperative non-repudiated message exchange from a first system to a second system in a computer network comprises checking for discrepancies between a current system time in the second system with an actual time; performing a time synchronization process to match the current system time with the actual time; exchanging public encryption keys between the first and second systems; sending a digitally signed message from the first system to the second system; decoding the digitally signed message; sending a digitally signed acknowledgment message from the second system to the first system; decoding the digitally signed acknowledgment message; and committing text of the digitally signed message to an official transcript on the first system.

Cooperative non-repudiated message exchange in a network environment

Systems, methods, and program products are provided for switching identity of a user that has a first username associated with a first class of users. According to the method, login information is received from the user, with the login information including the first username, an alternate class, and a password. The user is authenticated based on the first username and the password, and access to the computer system is provided as the alternate class, with the alternate class being different than the first class. In one preferred embodiment, the login information further includes a second username, and access to the computer system is provided with the rights and privileges of the second username.

Authentication to a second application using credentials authenticated to a first application

A computer program capsule is created from programs that include at least one other web service program. The programs are interconnected and saved as an encapsulated program for use as an encapsulated program or a web service program. The encapsulated program is created and interconnected from a local or remote computer.
