Scalable authentication process selection based upon sensor inputs

1. A mobile device comprising:

a plurality of sensors; and

a processor configured to:

determine multiple authentication processes based upon one or more sensor inputs and mobile device capabilities for authentication with at least one of an application or a service provider;

select an authentication process including the one or more sensor inputs from the multiple authentication processes that satisfies a security requirement in which a trust index calculated as a summation of values of each of the one or more sensor inputs is greater than a risk index calculated as a summation of values of one or more contextual inputs including user data and environmental data, wherein the authentication process is selected or not selected based on at least one of measured ambient levels of sound, light, or motion used to weight the value of the one or more sensor inputs; and

execute the selected authentication process.

2. The mobile device of claim 1 , wherein, the processor is further configured to determine the risk index based upon contextual inputs including at least one of demographic data, transaction data, or location data.

3. The mobile device of claim 2 , wherein, the processor is further configured to determine the trust index based upon the sensor inputs including at least one of a voice scan, a facial scan, or a fingerprint scan.

4. The mobile device of claim 1 , wherein, authentication processes are user-defined.

5. A method comprising:

determining multiple authentication processes based upon one or more sensor inputs and mobile device capabilities for authentication with at least one of an application or a service provider;

selecting an authentication process including the one or more sensor inputs from the multiple authentication processes that satisfies a security requirement in which a trust index calculated as a summation of values of each of the one or more sensor inputs is greater than a risk index calculated as a summation of values of one or more contextual inputs including user data and environmental data, wherein the authentication process is selected or not selected based on at least one of measured ambient levels of sound, light, or motion used to weight the value of the one or more sensor inputs; and

executing the selected authentication process.

6. The method of claim 5 , further comprising determining the risk index based upon contextual inputs including at least one of demographic data, transaction data, or location data.

7. The method of claim 6 , further comprising determining the trust index based upon the sensor inputs including at least one of a voice scan, a facial scan, or a fingerprint scan.

8. The method of claim 5 , wherein, authentication processes are user-defined.

9. A non-transitory computer-readable medium including code that, when executed by a processor, causes the processor to:

determine multiple authentication processes based upon one or more sensor inputs and mobile device capabilities for authentication with at least one of an application or a service provider;

select an authentication process including the one or more sensor inputs from the multiple authentication processes that satisfies a security requirement in which a trust index calculated as a summation of values of each of the one or more sensor inputs is greater than a risk index calculated as a summation of values of one or more contextual inputs including user data and environmental data, wherein the authentication process is selected or not selected based on at least one of measured ambient levels of sound, light, or motion used to weight the value of the one or more sensor inputs; and

execute the selected authentication process.

10. The computer-readable medium of claim 9 , further comprising code for determining the risk index based upon contextual inputs including at least one of demographic data, transaction data, or location data.

11. The computer-readable medium of claim 10 , further comprising code for determining the trust index based upon the sensor inputs including at least one of a voice scan, a facial scan, or a fingerprint scan.

12. The computer-readable medium of claim 9 , further comprising code for allowing user-defined authentication processes.

13. A mobile device comprising:

means for determining multiple authentication processes based upon one or more sensor inputs and mobile device capabilities for authentication with at least one of an application or a service provider;

means for selecting an authentication process including the one or more sensor inputs from the multiple authentication processes that satisfies a security requirement in which a trust index calculated as a summation of values of each of the one or more sensor inputs is greater than a risk index calculated as a summation of values of one or more contextual inputs including user data and environmental data, wherein the authentication process is selected or not selected based on at least one of measured ambient levels of sound, light, or motion used to weight the value of the one or more sensor inputs; and

means for executing the selected authentication process.

14. The mobile device of claim 13 , further comprising means for determining the risk index based upon contextual inputs including at least one of demographic data, transaction data, or location data.

15. The mobile device of claim 14 , further comprising means for determining the trust index based upon the sensor inputs including at least one of a voice scan, a facial scan, or a fingerprint scan.

16. The mobile device of claim 13 , further comprising means for allowing user-defined authentication processes.
