Method and apparatus of identifying a transaction risk
First Claim
1. A method implemented by one or more computing devices, the method comprising:
- building a relationship network with entities and activities relating to a plurality of transactions;
partitioning the relationship network, in real time or at fixed intervals, into a plurality of unconnected sub-networks based on connectivity by;
comparing current node information and historical node information to determine and label node change information,processing the deleted and split sub-networks using the node change information, andprocessing newly added and merged sub-networks using the node change information;
acquiring a sub-network, to which a node relating to a transaction to be identified belongs, the transaction being one of the plurality of transactions;
obtaining risk identification information of the sub-network to which the node relating to the transaction to be identified belongs, the risk identification information of the sub-network including one or more of a static property of the sub-network, and dynamic change information of the sub-network that is caused by the transaction to be identified;
identifying a risk of the transaction to be identified based at least in part on the risk identification information of the sub-network to which the node relating to the transaction to be identified belongs; and
labeling the node relating to the transaction to be identified belongs as a risk node.

Abstract
A method and an apparatus for identifying a transaction risk are disclosed. The method includes obtaining risk identification information of a sub-network to which a node relating to a transaction to be identified belongs; and identifying a risk of the transaction to be identified based on the risk identification information of the sub-network to which the node relating to the transaction to be identified belongs, wherein the sub-network is a network acquired by partitioning a relationship network based on connectivity, the relationship network is a network built up with entities and activities relating to a plurality of transactions. Embodiments of the present disclosure build up entities and activities relating to a transaction to be identified into a relationship network, and identify whether a risk exists in the transaction to be identified using risk identification information of the network which is difficult to be found or changed, and thus are able to identify a transaction risk in a more effective manner.

15. An apparatus comprising:
-
one or more processors; and memory coupled to the one or more processors, the memory storing a plurality of units executable by the one or more processors, the plurality of units including; an acquisition unit configured to obtain risk identification information of a sub-network to which a node relating to a transaction to be identified belongs, the risk identification information of the sub-network including one or more of a static property of the sub-network, and dynamic change information of the sub-network that is caused by the transaction to be identified; a risk identification unit configured to identify a risk of the transaction to be identified based on the risk identification information of the sub-network to which the node relating to the transaction to be identified belongs; and a labeling unit configured to label the transaction as having the risk and to label the node relating to the transaction to be identified belongs as a risk node, wherein the sub-network is a network acquired by partitioning a relationship network, in real time or at fixed intervals, into a plurality of unconnected sub-networks based on connectivity, and the relationship network is a network built up from entities and activities relating to a plurality of transactions. - View Dependent Claims (16, 17, 18)

19. One or more computer-readable media storing executable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:
-
building a relationship network with entities and activities relating to a plurality of transactions; partitioning the relationship network, in real time or at fixed intervals, into a plurality of unconnected sub-networks based on connectivity by; comparing current node information and historical node information to determine and label node change information, processing the deleted and split sub-networks using the node change information, and processing newly added and merged sub-networks using the node change information; acquiring a sub-network, to which a node relating to a transaction to be identified belongs, the transaction being one of the plurality of transactions; obtaining risk identification information of the sub-network to which the node relating to the transaction to be identified belongs, the risk identification information of the sub-network including one or more of a static property of the sub-network, and dynamic change information of the sub-network that is caused by the transaction to be identified; identifying a risk of the transaction to be identified based at least in part on the risk identification information of the sub-network to which the node relating to the transaction to be identified belongs, identifying the risk of the transaction to be identified including; upon identifying that the risk identification information of the sub-network includes the static property of the sub-network, calculating a ratio between a number of events and a number of nodes in the sub-network to which the node relating to the transaction to be identified belongs, determining whether the ratio between the number of events and the number of nodes in the sub-network to which the node relating to the transaction to be identified belongs exceeds a set ratio range, and determining that a potential risk exists in the transaction to be identified in response to determining that the ratio between the number of events and the number of nodes in the sub-network to which the node relating to the transaction to be identified belongs exceeds the set ratio range; and upon identifying that the risk identification information of the sub-network includes the dynamic change information of the sub-network that is caused by the transaction to be identified, calculating a density of the sub-network to which the node relating to the transaction to be identified belongs, determining whether the density of the sub-network to which the node relating to the transaction to be identified belongs exceeds a set density range, and determining that the potential risk exists in the transaction to be identified in response to determining that the density of the sub-network to which the node relating to the transaction to be identified belongs exceeds the set density range; and labeling the node relating to the transaction to be identified belongs as a risk node. - View Dependent Claims (20)
