Abstract: Methods, apparatuses, and articles for receiving, by a server, a plurality of identifiers associated with a client device are described herein. The server may also encrypt a plurality of encoding values associated with the plurality of identifiers using a first key of a key pair of the server, and generate a token uniquely identifying the client device, a body of the token including the encrypted plurality of encoding values. In other embodiments, the server may receive a token along with the plurality of identifiers. In such embodiments, the server may further verify the validity of the received token, including attempting to decrypt a body of the received token with a key associated with a second server, the second server having generated the received token, and, if decryption succeeds, comparing ones of the plurality of identifiers with second identifiers found in the decrypted body to check for inconsistencies.

Abstract: Methods, apparatuses, and articles for enabling, by a computing device, provision of a visual manifestation of an object of interest and of one or more other objects related to the object of interest to a user of the computing device, are described herein. In various embodiments, the one or more other objects may be arranged in a manner conveying a degree of relationship, the visual manifestation further including a first indication of at least one exceptional relationship between any two objects or a second indication of a security status of one of the objects. Further, the computing device may facilitate the user in interacting with the visual manifestation, including altering or expanding the visual manifestation in response to a user interaction.

Abstract: Embodiments of the present invention provide methods, servers and articles of manufacture that detect and prevent man-in-the-middle phishing attacks. This includes receiving device-specific information from a client device at a fraud prevention server, appending at least one of an internet protocol (IP) address and/or a timestamp to the device-specific information, and forwarding the appended device-specific information back to the client device for providing to an network service server for use by the network service server to facilitate recognition of the client device via at least one of the IP address and/or the timestamp.

Abstract: A method and apparatus for efficiently classifying and categorizing data objects such as electronic text, graphics, and audio based documents within very-large-scale hierarchical classification trees is provided. In accordance with one embodiment of the invention, a first node of a plurality of nodes of a subject hierarchy is selected. Previously classified data objects corresponding to a selected first node of a subject hierarchy as well as any associated sub-nodes of the selected node are aggregated to form a content class of data objects. Similarly, data objects corresponding to sibling nodes of the selected node and any associated sub-nodes of the sibling nodes are then aggregated to form an anti-content class of data objects. Features are then extracted from each of the content class of data objects and the anti-content class of data objects to facilitate characterization of said previously classified data objects.
