A computer program product comprising one or more non-transitory computer readable media comprising computer-executable instructions that, when executed by a processor associated with a user device, the user device comprising the processor, a display, and a detection device for capturing a field of view in proximity to the display, execute a method comprising:
- creating a user profile associated with a user, wherein the user profile includes a plurality of biometric features associated with the user and a weight associated with each of the plurality of biometric features;
- creating a file profile associated with a file, wherein the file profile includes an authorized user, functions that the authorized user can perform on the file, and a minimum confidence level required for the user to be identified as the authorized user;
- upon detecting in the field of view a person,
- determining a first biometric feature of the person;
- calculating a confidence level using:
- the first biometric feature of the plurality of biometric features of the person,
- the plurality of biometric features from the user profile, and
- the weight associated with each of the plurality of biometric features of the user profile;
- if the calculated confidence level exceeds a predetermined threshold, identifying the person as the authorized user for the file;
- if the calculated confidence level falls below the predetermined threshold, requesting the person to provide an additional biometric feature of the plurality of biometric features, and re-calculating the confidence level with the additional biometric feature and the weight associated with the additional biometric feature until either the calculated confidence level exceeds the predetermined threshold or there are no more additional biometric features of the plurality of biometric features to be determined, in which case the user is not identified as the authorized user;
- if the person is identified as the authorized user, activating the display to allow the authorized user to perform the functions that the authorized user can perform on the file;
- and
- if the person is not identified as the authorized user, deactivating the display to prevent the person from performing the functions that the authorized user can perform on the file.
