20110107104METHOD, SYSTEM, AND DEVICE FOR NEGOTIATING SA ON IPv6 NETWORK - A method, system, and device for negotiating a security association (SA) on an Internet Protocol version 6 (IPv6) network are disclosed. In this method, the initiator and the responder generate an SA through the interaction of two messages. Compared with the conventional procedure for setting up an SA based on the Internet Key Exchange Protocol (IKE), the interaction procedure in the present invention is simplified significantly. Therefore, the negotiation is faster and more convenient. In addition, with the present invention, cryptographically generated address parameters (CGA Params) are carried in the message and the CGA may be verified so that the invader cannot spoof the address.05-05-2011
20110119534METHOD AND APPARATUS FOR PROCESSING PACKETS - A method and apparatus for processing packets are provided to extend the usage of a Cryptographically Generated Addresses (CGA) protocol. The method includes: receiving an Internet Protocol version 6 (IPv6) packet carrying CGA related information from a sender; obtaining the CGA related information from the IPv6 packet at the network layer, where the CGA related information includes the CGA parameters (CGA Params) and CGA signature (CGA Sig) of the sender; verifying the source address of the IPv6 packet according to the CGA Params and CGA Sig; transmitting the payload of the IPv6 packet after the verification succeeds. In the present invention, the packet is not limited to the IPv6 packet; the IP packet of a version later than IPv6 or the IP packet compatible with IPv6 may also be used.05-19-2011

20100228614AdHeat Advertisement Model for Social Network - In one implementation, a computer-implemented method includes receiving at a server information indicating activity levels of users of a computer-implemented social network or acquaintance relationships of the users on the computer-implemented social network. The method further includes generating by the server influence scores for the users based on the received information. The method also includes recursively propagating by the server an ad through the computer-implemented social network between users having an acquaintance relationship by transmitting the ad from a propagating user to a recipient user when a difference between a first influence score of the propagating user and a second influence score of the recipient user is greater than a threshold.09-09-2010
20100228631Bidding on Users - In one implementation, a computer-implemented method includes receiving at a server a request from an advertiser to target an ad to users of a computer-implemented social network, the request comprising data representing characteristics of the users that the advertiser desires to target. The method further includes ranking the users based on how similar the users' characteristics are to the received characteristics and an influence score for each user that indicates how influential the user is within the social network. The method also includes scoring the advertiser's request based on a bid from the advertiser for an opportunity to display the ad to one or more of the users and assigning the opportunity to display the ad to the one or more users based on a correlation between a score of the advertiser's request and one or more rankings of the one or more users.09-09-2010
20110022602Ranking Social Network Objects - An online social networking system can be used to rank social network objects of various different object types, each according to its type. The objects may comprise types such as users, communities, blogs, blog entries, events, forums, forum topics, postings, photographs, and/or images. The product comprises code for carrying out a method that begins with receiving ranking data about social network objects that comprises data about events performed on the social network. For each social network object, a ranking function is applied to ranking data about the social network object based on its type. In addition, the recency of an event on the social network related to the social network object is evaluated, in order to calculate the score for the social network object. A relative ranking for each of the plurality of social network objects based on its score is determined, and the score and relative ranking of each of the social network objects stored.01-27-2011
