摘要： Systems and methods to perform efficient searching for web content using a search engine are provided. In an illustrative implementation, a computing environment comprises a search engine computing application having an essential pages module operative to execute one or more selected selection algorithms to select content from a cooperating data store. In an illustrative operation, the exemplary search engine executes on a received search query to generate search results. Operatively, the retrieved results can be generated based upon their joint coverage of the submitted search query by deploying a selected sequential forward floating selection (SFFS) algorithm executing on the essential pages module. In the illustrative operation, the SFFS algorithm can operate to iteratively add one and delete one element from the set to improve a coverage score until no further improvement can be attained. The resultant processed search results can be considered essential pages.

摘要： Functionality is described for reducing the unauthorized reproduction of optical media, such as optical discs of various types. The functionality operates by adding a physical descriptor to an optical medium, forming reference descriptor information based on the descriptor (by reading the descriptor Lr times), producing authenticity information based on the reference descriptor information, and providing the authenticity information to a disc use site via various modes. At the disc use site, the functionality operates by reading the authenticity information and reading the descriptor Lv times (where Lv may not equal Lr). Based on the information that is read, the functionality performs cryptographic analysis and descriptor-based analysis to validate the optical medium. The descriptor can be formed on a closed loop of the optical medium. The functionality also includes provisions for reducing the possibility that unwanted correction is performed, which may interfere with analysis of the descriptor.

摘要： Radio frequency certificates of authenticity (RFCOAs) and associated scanners and methods are presented. In one implementation, an array of miniaturized antenna elements in an RFCOA scanner occupies an area smaller than a credit card yet obtains a unique electromagnetic fingerprint from an RFCOA associated with an item, such as the credit card. The antenna elements are miniaturized by a combination of both folding and meandering the antenna patch components. The electromagnetic fingerprint of an exemplary RFCOA embeddable in a credit card or other item is computationally infeasible to fake, and the RFCOA cannot be physically copied or counterfeited based only on possession of the electromagnetic fingerprint.

摘要： Described herein is a watermarking technology for protecting digital signals, such as a music clip. In another described implementation, a watermarking system employs a permutation technique to hide a watermark. The order in which data is imposed or encoded is rearranged may be based upon a permutation table. The same table may be used to reverse permute the data at the detector.

摘要： Seller's reputation quantification technique embodiments are presented that quantify in monetary terms a risk of dissatisfaction to a potential buyer of a product or service from a seller in an on-line consumer market. Generally, this involves computing the monetary sales limit for the seller. This monetary sales limit represents an amount, which if a sum of the current prices of all the products and services currently offered by the seller is equal to or less than the amount, there would not be a significant risk to the buyer of being dissatisfied with the product or service. Given this, a risk of a potential buyer's dissatisfaction with a product or service purchased from the seller in view of a price the buyer wants to pay is assessed. The assessed risk is then provided to the potential buyer in the form of one or more risk indicators.

摘要： Described herein is a technology for facilitating watermark detection. Spread-spectrum watermarking is a commonly employed technique for hiding data in digital goods (e.g., multimedia signals). Such watermarks may be potentially vulnerable to so-called “watermark estimation-based attacks.” At least one implementation, described herein, is an advancement over the traditional spread-spectrum watermark detector. At least one implementation, described herein, greatly discourages an estimation-based attack by an adversary. At least one implementation, described herein, determines whether a digital good has likely been subjected to an estimation-based attack and, at least, approximately reverses such attack. The scope of the present invention is pointed out in the appending claims.

摘要： The subject matter includes systems, engines, methods, and schemata for embedding spread-spectrum fingerprints in multimedia content: a first fingerprint to identify a recipient of the multimedia content and a second fingerprint at a location in the first fingerprint that represents a subset of a much larger group of recipients. By locating the second fingerprint, the search for a media pirate is immediately narrowed down to the subset, thus immensely speeding up pirate identification. In one implementation, chips of the second fingerprint can be made small and embedded sparsely, making alteration difficult. Systems, engines, methods, and schemata for synchronizing a pirated copy with original multimedia content to facilitate fingerprint recovery are also described.
