1. A method for enrolling a user of a gun, the method comprising:
receiving, from a first authentication sensor of the gun, first enrollment biometric data;
receiving, from a second authentication sensor of the gun, second enrollment data;
transforming the first enrollment biometric data into first transformed data;
transforming the second enrollment data into second transformed data;
generating a user profile for the user, the user profile comprising the first transformed data and the second transformed data;
storing the user profile in non-volatile memory of the gun;
receiving query biometric data from the first authentication sensor or the second authentication sensor;
determining that the query biometric data corresponds to the user;
producing a measurement of light at an ambient light sensor of the gun; and
performing, based on the measurement of light, a function at a component of the gun in response to the determining that the query biometric data corresponds to the user.
 
8. The method of claim 1, further comprising:
generating a transformation key at the gun, wherein the transforming the first enrollment biometric data is based on the transformation key.
