Abstract

An example method for performing concepts disclosed can include: obtaining a first authentication factor including first biometric data of a user; hashing the first authentication factor to create a first hash; registering the user with a digital credit system using the created first hash; obtaining a second authentication factor including second biometric data of the user; hashing the second authentication factor to create a second hash; comparing the first hash and the second hash; and proceeding the transaction based on the comparison.
