Parameter-based computer evaluation of user accounts based on user account data stored in one or more databases
A user account evaluation system is disclosed for evaluating risk associated with a user account. The system may obtain user account data associated with many user accounts, select a statistically significant subset of the user accounts, and then process (e.g., to determine types of the user accounts, etc.) and analyze the subset of user accounts to generate a plurality of evaluation models. When a new user account is accessed by the system, user account data may be obtained for the new user account, and the new user account may be evaluated based on the plurality of evaluation models. Accordingly, a plurality of evaluation parameter scores may be generated for the new user account, each of which may indicate an amount of risk associated with the user account. Some embodiments of the present disclosure may include machine learning and/or artificial intelligence methods to improve evaluation of the user accounts.
