Adaptive risk-based verification and authentication platform

A system comprising:

• one or more processors of a server;
• and
• a non-transitory machine-readable storage medium coupled to the one or more processors, the machine-readable storage medium embodying instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, by a server, a request from a user to perform an action to sell an item on an e-commerce site, the request comprising search data, the item being identified in response to:
• extracting one or more words from the search data;
• and
• storing the extracted words in a database in association with the item;
• retrieving a first risk assessment factor associated with the user;
• retrieving a second risk assessment factor associated with the action on the item;
• training a neural network to implement a risk assessment model by performing training operations comprising:
• processing training data by the neural network to estimate a risk assessment level corresponding to the risk assessment model that is used to determine that the action is not permitted;
• incrementally changing internal weights of the neural network used to generate the estimate of the risk assessment level;
• and
• updating a final outcome produced by the neural network in response to incrementally changing the internal weights of the neural network;
• automatically determining, by the server, the action is not permitted based on a new risk assessment level generated by the risk assessment model, the risk assessment model comprising a plurality of factors including at least the first risk assessment factor and the second risk assessment factor;
• identifying a risk mitigation process from a plurality of risk mitigation processes based on the new risk assessment level generated by the risk assessment model, a first of the risk mitigation processes being associated with a first type of risk determined by the risk assessment model, a second of the risk mitigation processes being associated with a second type of risk determined by the risk assessment model, the first of the risk mitigation processes including analysis of seller feedback information, and the second of the risk mitigation processes including obtaining identity verification information from the user;
• communicating the identified risk mitigation process to the user;
• in response to communicating the identified risk mitigation process to the user, receiving, by the server, risk mitigation data from the user corresponding to the identified risk mitigation process;
• and
• in response to receiving the risk mitigation data from the user, automatically modifying, by the server, the new risk assessment level generated by the risk assessment model.
