Methods and systems for authenticating users
A method of authenticating users to reduce transaction risks includes indicating a desire to conduct a transaction and determining whether the transaction requires access to protected resources. Moreover, the method determines whether inputted information is known, determines a state of a communications device when the inputted information is known, and transmits a biometric authentication request from a server to an authentication system when the state of the communications device is enrolled. Additionally, the method includes validating the communications device, capturing biometric authentication data in accordance with a biometric authentication data capture request with the communications device, biometrically authenticating the user, generating a one-time pass-phrase and storing the one-time pass-phrase on the authentication system when the user is authenticated, comparing the transmitted one-time pass-phrase against the stored one-time pass-phrase, and granting access to the protected resources when the transmitted and stored one-time pass-phrases match.
1. A method for authenticating users comprising:
obtaining a unique user identifier from a user;
determining whether the obtained unique user identifier matches a user identifier and, upon determining a match, determining a risk level corresponding to a transaction;
determining a capture level for the determined risk level;
after inputting the capture level into a processor, determining a biometric authentication data requirement corresponding to the capture level with the processor;
validating the user with data corresponding to the biometric authentication data requirement; and
conducting the transaction after successfully validating the user.
2. A method of authenticating users in accordance with claim 1 , said determining a risk level step comprising determining a different risk level for different transactions.
3. A method of authenticating users in accordance with claim 1 , said determining a biometric authentication data requirement step comprising determining more demanding biometric authentication data requirements as the risk level increases.
4. A method of authenticating users in accordance with claim 1 , said determining a risk level step comprising:
determining a risk factor for the transaction and a risk level adjustment for the risk factor; and
adjusting the determined risk level according to the risk level adjustment.
5. A method of authenticating users in accordance with claim 1 further comprising:
determining that a plurality of transactions is pending;
determining the risk level for each pending transaction; and
determining a maximum risk level to be the determined risk level.
6. A method for authenticating users in accordance with claim 1 , further comprising validating the user with authentication data after the user is successfully validated in said validating step, the authentication data being different than the data corresponding to the biometric authentication data requirement.
7. A method for authenticating users comprising:
determining a risk level corresponding to a transaction desired to be conducted by a user and including the determined risk level in an authentication request;
determining a capture level for the determined risk level;
after inputting the capture level into a processor, determining an authentication data requirement corresponding to the capture level with the processor; and
validating the user with data corresponding to the authentication data requirement.
8. A method for authenticating users in accordance with claim 7 , further comprising determining whether a unique user identifier matches a user identifier and when there is a match conducting said determining a risk level step.
9. A method for authenticating users in accordance with claim 7 , further comprising determining the authentication data requirement includes different biometric types as the risk level increases.
10. A method for authenticating users in accordance with claim 7 , said determining an authentication data requirement step further comprising adjusting the determined risk level according to a risk level adjustment for the transaction.
11. A method for authenticating users in accordance with claim 7 , said validating step comprising comparing biometric data captured from the user against user biometric data with the processor, wherein the captured and user biometric data correspond to the authentication data requirement.
12. A method for authenticating users in accordance with claim 7 , said validating step comprising comparing biometric data captured from the user against corresponding user biometric data with a second processor remote from the processor.
13. A method for authenticating users in accordance with claim 7 , said determining an authentication data requirement step comprising comparing the determined risk level against an authentication policy with the processor to determine a matching risk level, wherein the authentication data requirement corresponds to the matching risk level.
14. A method for authenticating users in accordance with claim 7 , said determining an authentication data requirement step comprising comparing the determined risk level against an authentication policy with a second processor remote from the processor, wherein the authentication data requirement corresponds to the matching risk level.
15. A method for authenticating users in accordance with claim 7 , wherein:
said validating step comprises comparing biometric data captured from the user against corresponding user biometric data with the processor, the processor being included in an authentication system; and
said determining an authentication data requirement step comprises comparing the determined risk level against an authentication policy with a second processor included in a communications device, the communications device being remote from the authentication system.
16. A method for authenticating users comprising:
determining a risk level for a transaction desired to be conducted by a user and including the determined risk level in an authentication request;
extracting the risk level from the authentication request with a processor; and
determining an authentication data requirement corresponding to the risk level.
17. A method for authenticating users in accordance with claim 16 further comprising conducting the transaction after successfully validating the user with data corresponding to the authentication data requirement.
18. A method for authenticating users in accordance with claim 17 further comprising:
conducting a first authentication transaction with face biometric data captured from a user to authenticate the user;
conducting a second authentication transaction with authentication data captured from the user to authenticate the user after successfully authenticating the user in the first authentication transaction, the authentication data for the second transaction being different than the authentication data for the first transaction; and
validating the user after the user is successfully authenticated in the second authentication transaction.
19. A method for authenticating users comprising:
conducting, by a processor, a first authentication transaction with face biometric data captured from a user to authenticate the user;
conducting a second authentication transaction with authentication data captured from the user to authenticate the user after successfully authenticating the user in the first authentication transaction, the authentication data for the second transaction being different than the authentication data for the first transaction; and
validating the user after the user is successfully authenticated in the second authentication transaction.
