摘要： A mobile communications device includes a plurality of first input devices capable of passively collecting input data, a second input device(s) capable of collecting response data based upon a challenge, and a processor capable of determining a level of assurance (LOA) that possession of the mobile communications device has not changed based upon a statistical behavioral model and the passively received input data, and comparing the LOA with a security threshold. When the LOA is above the security threshold, the processor may be capable of performing a given mobile device operation without requiring response data from the second input device(s). When the LOA falls below the security threshold, the processor may be capable of generating the challenge, performing the given mobile device operation responsive to valid response data, and adding recent input data to the statistical behavioral model responsive to receipt of the valid response data.

摘要： A method of operation and non-transitory computer readable medium are provided for a mobile communications device which includes memory storing program instructions and a processor coupled to a first input that passively collects input data and a second input that collects response data based on a challenge. A statistical behavioral model is generated based upon passively collected input data for the user. A level of assurance (LOA) is determined based upon the statistical behavioral model and the passively collected input data from the first input. The LOA is compared with a threshold and based on the comparison: the mobile device operation is enabled as a result of determining that the LOA meets or exceeds the threshold without requiring response data from the at least one second input, otherwise, the challenge is generated and the mobile device operation is enabled responsive to valid response data from the second input.
