A system and method for communicating information between a first party and a second party, comprising the steps of receiving, by an intermediary, an identifier of desired information and accounting information for a transaction involving the information from the first party, transmitting an identifier of the first party to the second party, and negotiating, by the intermediary, a comprehension function for obscuring at least a portion of the information communicated between the first party and the second party. The data transmission may be made secure with respect to the intermediary by providing an asymmetric key or direct key exchange for encryption of the communication between the first and second party. The data transmission may be made secure with respect to the second party by maintaining the information in encrypted format at the second party, with the decryption key held only by the intermediary, and transmitting a secure composite of the decryption key and a new encryption key to the second party for transcoding of the data record, and providing the new decryption key to the first party, so that the information transmitted to the first party can be comprehended by it.

An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

A system and method for conducting a multi-person, interactive auction, in a variety of formats, without using a human auctioneer to conduct the auction. The system is preferably implemented in software. The system allows a group of bidders to interactively place bids over a computer or communications network. Those bids are recorded by the system and the bidders are updated with the current auction status information. When appropriate, the system closes the auction from further bidding and notifies the winning bidders and losers as to the auction outcome.

A diverse goods arbitration system and method allocates computer resources among bidding requesters. Bid slates are transmitted to an arbiter by users (requesters) requesting use of specified portions of the available computer resources. Each bid slate may contain a plurality of bids, each bid representing a requested set of resources and a bid price. The arbiter selects combinations of bids from the bid slates, where each bid combination consists of no more than one bid from each of the received bid slates. The arbiter rejects all bid combinations whose constituent bids exceed an established maximum allocation level for any computer resource. It then selects as a winning bid combination the bid combination having the highest total bid price. Computer resources are then allocated for a next time period based on the winning bid. Costs are allocating to each successful requester in accordance with a predefined opportunity cost function. In particular, for each successful requester, the arbitration process is repeated while excluding that successful requester's bid slate from the set of bid slates considered, resulting in the selection of a second winning bid that excludes the successful requester. The successful requester is then assessed a cost corresponding to the difference between the winning bid's total bid prices, excluding the price in the successful requester's granted bid, and the total bid prices associated with the second winning bid.

An electronic communication authority server that provides centralized key management, implementation of role-based enterprise policies and workflow and projection of corporate authorities over trusted networks. The authority server includes a key database that associates keys, signatures and indicators of corporate authority (such as letterhead) with particular corporate roles. There can be multiple roles or a single role (e.g., employee) for each authority server. Users associated with one or more roles are permitted by the authority server to exercise authority or include the indicators of authority in their communications. The authority server also encrypts/decrypts and signs/verifies communications from/to a user using the keys and signatures associated with the role being exercised by the user for that communication. The authority server permits roles to be delegated or transferred, which facilitates the execution by the authority server of role-dependent workflow procedures. In another embodiment, keys are not associated with individual roles but with servers and/or groups of users. In this embodiment a server processes a request from one of its users in accordance with the role-based policies it embodies and then, if necessary, indicates the identity of the requesting user in the end product of the request, which it then signs using its own key and encrypts with appropriate destination keys.

A system and method is disclosed that provides persistent capabilities for distributed, object-oriented applications running on generally available hardware. The disclosed system and method operate in a transparent distributed object system where inter-process messaging between the program objects is effected by paired transport managers, proxies and matched in-table and out-table slots. Each object needing to communicate with an object in another address space does so by transparently issuing messages to that object's local proxy. Each process provides a registrar that includes a secret code table wherein an object is registered with a unique, practically unguessable secret code. Anticipating the need to re-establish object-proxy links following a inter-process communications fault, proxies are made revivable, meaning that their links with corresponding remote objects can be revived following a communications interruption. This is accomplished by a makeRevivable method that stores a revivable proxy's expiration date (the date beyond which the proxy is not revivable) and its corresponding remote object's secret code into the proxy's out-table slot. Upon the occurrence of a communications fault, all transport managers and tables are nulled out and then, when the communications fault is corrected, rebuilt by the transport managers. Sometime after the restoration of communications, a revived method is invoked that restores the links between, registered objects and proxies. The objects and proxies are brought back in a consistent state based on limited checkpointed data stored by the distributed program for the registered objects.

Persistent distributed capabilities

Programmers write programs, expressing plans for machines to execute. When composed so that they may cooperate, plans may instead interfere with each other in unanticipated ways. Plan coordination is the art of simultaneously enabling plans to cooperate, while avoiding hazards of destructive plan interference. For sequential computation within a single machine, object programming supports plan coordination well. For concurrent computation, this paper shows how hard it is to use locking to prevent plans from interfering without also destroying their ability to cooperate.

Concurrency Among Strangers

A distributed garbage collection system and method is disclosed that is compatible with local ref-count or full garbage collection and that ensures that no local object's storage is deleted by the local garbage collector unless it is certain that there are no actual or potential remote references to that local object. The disclosed system and method are implemented in the context of a transparent distributed object system in which communications between objects in different processes are enabled by dedicated proxy objects that are linked to corresponding remote objects via a pair of transport objects. Additional proxy holder objects and proxy holder proxies ensure that objects for which third-party object references are passed (i.e., where one object in a first process passes a remote object in a second process a reference to a third object in a third process) are not collected until a direct link is established between the remote object in the second process and the third object in the third object space. As appropriate, secret number table pointers maintained by a local registrar for each object that has been accessed via a third party message are deleted, allowing the objects to be collected when there are no other actual or pending remote references to that object. The transport managers encrypt all inter-process messages so as to provide full capability security within the distributed system. This enables the disclosed garbage collection system and methods to operate under attack from misbehaving participants.
