User authentication

A computer-implemented system, comprising:

• one or more processors;
• a memory coupled to at least one of the processors;
• and
• a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of:
• receiving during an initial phase a plurality of biometric feature inputs from an input module of the user device wherein each of the biometric feature inputs is stored in the user device, and is used equally to authenticate one or more activities;
• assigning a weight to each of the one or more activities, and calculating a score for each of the biometric feature inputs based on a weighted frequency of an association of each of the biometric feature inputs with a specific activity from among the one or more activities;
• determining a primary biometric feature input from among the biometric feature inputs for the specific activity based on the primary biometric feature input having a higher score among the biometric feature inputs;
• and
• based on the determination of the primary biometric feature input, beginning a deployment phase, wherein access controlled operations require the primary biometric feature input for authentication.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions readable by a device to cause the device to perform a method comprising:

• receiving during an initial phase, by one or more processing units, a plurality of biometric feature inputs from an input module of the user device wherein each of the biometric feature inputs is stored in the user device, and is used equally to authenticate one or more activities;
• assigning a weight to each of the one or more activities, and calculating a score for each of the biometric feature inputs based on a weighted frequency of an association of each of the biometric feature inputs with a specific activity from among the one or more activities;
• determining a primary biometric feature input from among the biometric feature inputs for the specific activity based on the primary biometric feature input having a higher score among the biometric feature inputs;
• and
• based on the determination of the primary biometric feature input, beginning a deployment phase, wherein access controlled operations require the primary biometric feature input for authentication.
