Abstract:
In auctioning advertising opportunities presented over a network, dual pricing reduces effects of fraudulent behavior causing showing or selection of a bidder's ads. In addition to a per selection bid or per showing bid presented by a bidder, a constructive bid opposite that offered by the bidder is derived from the bid offered and a rate of expected selections per showing. The costs resulting from the number of times the ad is both shown and selected are monitored. The price paid by the bidder is determined by the lower of the two costs. Behavior by another party causing the ad to be fraudulently shown or selected will not affect the bidder unless the party causes both a high number of showings and a high number of selections. Setting a price over a plurality of auction periods reduces the effect of fraudulent behavior perpetrated by the bidder regarding its own ads.
Abstract:
An overlay network and scheme for building and using the overlay network are described. As the overlay network is built, new nodes joining the network are connected randomly with other nodes which results in a random graph as the network topology. The network is fully scalable, with each new node providing the same number of network connections for output to other nodes as it consumes when it joins the network. In addition, network coding is implemented at each node to mix packets of data entering each node using random linear functions. The network coding at each node generates new packets that are independent combinations of original data packets entering the node. The new coded packets make the distribution of data to other nodes more efficient and robust.
Abstract:
A concept for providing a process and apparatus for allocating a gamut of assets/resources across a spectrum of consumers is described. The concept includes an apparatus for allocating resources across a spectrum of users. The apparatus includes one or more processors and a memory coupled to the one or more processors. The memory is configured to store data representative of characteristics and capabilities of the resources and describing needs of the spectrum. The memory further includes computer readable code configured to cause the one or more processors to perform acts of: estimating current requests from the spectrum for the resources; comparing the current requests to the capabilities and characteristics; and allocating the resources with respect to the requests in conformance with a convex program implementation of Arrow-Debrue theory.
Abstract:
The present invention leverages an ellipsoid method with an approximate separation oracle to analyze network data routes for data dissemination by a source, yielding an optimization analysis process which compensates for networks with limited capacity links, traditionally an NP-hard problem. In one instance of the present invention, by utilizing a novel generalization of an ellipsoidal means to work with an approximate separation oracle, a primal as well as a dual linear program is solved within the same approximation factor as the approximate separation oracle. Performance of the present invention is within a 1.6 factor.
Abstract:
An archive of items, which are computing data accessed by a user, is created at a semantic object level. The object archiving may group seemingly disparate items as a composite object, which may then be stored to enable retrieval by the user at a later point in time. The composite object may include metadata from the various items to enable identifying the composite object and providing retrieval capabilities. In some aspects, an archiving process may extract item data from an item that is accessed by a computing device. Next, the item may be selected by a schema for inclusion in a composite object when the item data meets criteria specified in the schema. The composite object(s) may then be stored in an object store as an archive.
Abstract:
The claimed subject matter relates to a computer-implemented architecture that can facilitate computer-assisted haggling and/or negotiation between multiple parties simultaneously. For example, various proxies associated with both buyers and sellers can be configured to negotiate with other proxies to buy or sell an item. The negotiations can be required to be progressive and during the negotiations a buyer or seller is, typically, allowed to withdraw his or her proposals. The architecture can include a registration component that can resolve concurrency and facilitate a registration of an agreement between two of the parties. The registration of an agreement can create a binding obligation between the parties after which other outstanding proposals can be terminated.
Abstract:
Systems and methods for digitally certified stationery are described. In one aspect, a stationery granting authority (SGA) receives a request from a user to generate a document. If the user is authorized for the requested document, the SGA generates a certificate with credentialing information from data in the request. The SGA generates a first digital signature from some of the credentialing information. The SGA communicates the certificate to the user for editing and distribution as the document. A recipient of the document determines whether the document is “official” by contacting a specified service to provide certain information from the document. The verification service computes a second digital signature from the provided information for comparison to the first digital signature. If there is a match, the service notifies the recipient that the document is valid/official. Otherwise, the recipient is notified that the document is not valid.

Abstract:
Described herein is a search engine that can include a receiver component that receives a query from a user that pertains to a multimedia item and an output component that outputs multiple choices for receiving an instance of the multimedia item to a user. The multiple choices may include a first choice for receiving a first instance of the multimedia item for no charge, wherein the first instance of the multimedia item includes a digital rights management restriction. The multiple choices may also include a second choice for receiving a second instance of the multimedia item for a fee, wherein the second instance of the multimedia item is free of digital rights management restrictions. The search engine can further include a transmitter component that transmits one of the first multimedia item or the second multimedia item to the user.
Abstract:
Auction prices for a quantity of items, the quantity of which is not determined prior to auction, are equilibrated among bidders to reflect supply and demand for the items. For example, in auctioning Internet advertising opportunities, the first available opportunities are auctioned to a high bidder. Later in the course of the auction period, once the high bidder's budget has been exhausted, the price for advertising opportunities is reduced. The difference in price paid by the high bidder and the reduced price for the quantity of advertising opportunities purchased is credited to the high bidder's account. Once the high bidder's account regains a level sufficient to acquire additional advertising opportunities, the high bidder may continue to acquire advertising opportunities. Other bidders similarly are credited the difference between prices previously paid and the current price. An equilibrium price is reached based on the recursive adjustment of prices paid by the bidders.
