Abstract: A computer-implemented method for enhancing user authentication is provided. The method is implemented using an authentication computing device in communication with a memory. The method includes storing a plurality of user preferences associated with a user account. The user preferences are rule-based preferences that define steps to be taken for authenticating the user for accessing the user account. The method also includes receiving an authentication request for access to the user account, determining one or more authentication challenges based, at least in part, on the user preferences, transmitting the one or more authentication challenges to be presented to a user attempting to access the user account, and determining whether to authenticate the user based on a response to the one or more authentication challenges.

Abstract: A method for authorization of a blockchain transaction includes: storing account profiles, each profile including an account identifier, fiat amount, and blockchain amount; receiving a transaction message, the transaction message being formatted based on transaction message standards and including a first data element that includes a specific account identifier and a second data element reserved for private use that includes a network identifier and transaction amount; identifying a specific account profile that includes the specific account identifier; identifying a risk value based on the transaction amount and at least one of: the fiat amount and blockchain amount; determining authorization of a transaction based on the identified risk value; modifying the transaction message based on the authorization determination; and transmitting the modified transaction message.
