摘要： Systems and methods for security against corruption for networked storage are described. In one aspect, a destination device receives a linear combination of packets. The linear combination of packets represents digitally signed blocks of content and public information used to digitally sign segmented blocks of content. The destination device recombines the linear combination of packets to compute new valid signatures as linear combinations of received homomorphic digital signatures. The new valid signatures are for verifying by a requesting computing device recovering data associated with at least a subset of the linear combination of packets, integrity of the at least a subset. This provides the requesting node with security against corruption of data in networked storage.

摘要： 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.

摘要： Systems and methods to detect unauthorized changes to a printed document are described. In one aspect, a digital signature of original content associated with electronic document is embedded into the original content to create a content signed document. The systems and methods use the embedded digital signature to automatically determine whether text-based content associated with a printout of the content signed document was changed from the original content associated with the electronic document.

摘要： Digital signatures for network coding are described. In one aspect, digital signatures for network coding are described. In one aspect, segmented blocks of content for distribution are digitally signed using homomorphic digital signatures generated from an elliptic curve. A linear combination of packets comprising the digitally signed content is distributed to a destination device according to an implemented distribution scheme. The linear combination of packets includes public information when digitally signing the segmented blocks. The homomorphic digital signatures and the public information allow a device receiving one or more packets of the linear combination of packets to verify and authenticate content associated with the one of our packets independent of secure transmission of secret keys and hash digests used to digitally sign the one or more packets.

摘要： Systems and methods for secure signatures are described. In one aspect, a secure signature is generated. The secure signature strongly binds an image of an electronic signature (an “electronic signature”) to content in either electronic or printed form. Responsive to receiving a request from a user, the systems and methods determine whether an electronic signature associated with a printed page represents a secure signature. If so, the systems and methods determine and notify the user of whether the secure signature was cryptographically bound by a signer of the electronic signature to the content being signed.

摘要： Various embodiments provide techniques for advertisement inventory. In at least some embodiments, a scaled number of impressions can be matched to orders that have scaled impression goals. Impressions can be randomly selected from an offline traffic model and allocated to orders according to a matching algorithm until a number of impression defined by a scale factor is reached. This can occur by sampling the traffic model directly using the scale factor and/or by creating a scaled data set to which the matching algorithm can be applied. The matching algorithm can be configured to identify an order that is farthest away from being complete and then match the randomly selected impression to the identified order. If the scaled orders in the data set can be fulfilled using the scaled number of impressions, a conclusion is made that the original set of orders can be fulfilled using the original impressions.

摘要： A content provider may provide public access to a content item set, but may be unable to achieve sufficient revenue to sustain the administrative costs and ongoing development of the content item set. Instead, the content provider may develop relationships with one or more referrers (e.g., search engines.) When a user requests a content item, the content provider may determine whether the request results from a referral by a sponsoring referrer, and based on this determination may provide either a full version or a limited version of the content item. The referrer benefits by providing its users with free access to the content item set, which may be unavailable from non-sponsoring competitors, and in exchange may share advertising revenue with the content provider. This arrangement achieves sustaining sponsorship of the content provider while extending full and free access to the content item set to users of sponsoring referrers.

摘要： A method scheduling outgoing communication in a mobile device is provided. The method includes receiving a signal quality profile for an area in which the device is located. The method further includes receiving a signal from a user application stored on the device that requests the mobile device to make the outgoing communication. Additionally, the method includes determining a current location, a speed, a direction, and a signal quality associated with the device and determining whether the signal quality is above a certain threshold. If not, the method includes predicting a future time at which the signal quality will be above the threshold based at least on the current location, the speed, the direction, the signal quality, and the signal quality profile. Finally, the method includes scheduling the outgoing communication from the mobile device at the future time.

摘要： The claimed subject matter relates to an architecture that can facilitate auditing of a customer's possessions in a comprehensive manner. The architecture can facilitate the creation of a media archive of a customer's property, as well as an associated property list extracted based upon, e.g., examination of the archive. The property list can include an entry associated with an item of property and can be transmitted to subsidizing entities to offset the expenses associated with the creation of the archive and the property list.
