Method and apparatus for a digital exchange item marketplace network including buyer, seller, and device verification

A non-transitory computer readable memory device of an exchange item marketplace network comprises:

• a first memory section for storing operational instructions that, when executed by a server of the exchange item marketplace network, causes the server to:
• receive, from a plurality of seller computing devices, a plurality of requests to sell exchange items;
• a second memory section for storing operational instructions that, when executed by the server, causes the server to:
• for a request to sell of the plurality of requests to sell, process the request to sell by:
• verifying information regarding a seller computing device of the plurality of seller computing devices associated with the request to sell;
• when the information regarding the seller computing device is favorably verified, verifying information regarding an exchange item identified in the request to sell;
• and
• when the information regarding the exchange item is favorably verified, adding the exchange item to a digital exchange item marketplace;
• a third memory section for storing operational instructions that, when executed by the server, causes the server to:
• receive, from a plurality of buyer computing devices, a plurality of requests to buy exchange items from the digital exchange item marketplace;
• and
• a fourth memory section for storing operational instructions that, when executed by the server, causes the server to:
• for a request to buy of the plurality of requests to buy, process the request to buy by:
• verifying second information regarding a buyer computing device of the plurality of buyer computing devices associated with the request to buy, wherein the verifying includes:
• obtaining, as the second information, user information and device associated with the buyer computing device;
• selecting a fraud determination approach of a plurality of fraud determination approaches based on the second information, wherein the selected fraud determination approach includes a traversing of a fraud decision tree, wherein the fraud decision tree includes a plurality of nodes organized in a decision tree structure, and wherein the plurality of nodes includes one or more question nodes and two or more end nodes;
• performing a decision tree analysis function on the fraud decision tree to produce a composite fraud score for the request to buy, wherein the decision tree analysis function traverses through two or more nodes of the plurality of nodes to arrive at an end node of the two or more end nodes, wherein each node of the plurality of nodes is associated with a scoring result, wherein the composite fraud score is based on summing the scoring result associated with each traversed node of the fraud decision tree;
• and
• determining whether the composite fraud score compares favorably to a fraud threshold;
• when the composite fraud score compares favorably to the fraud threshold verifying payment information associated with the buyer computing device regarding purchasing of a selected exchange item;
• and
• when the payment information is favorably verified:
• processing payment for the selected exchange item;
• removing the selected exchange item from the digital exchange item marketplace;
• and
• adding the selected exchange item to a digital wallet associated with the buyer computing device.
