               1. A system for managing access to a display of a user device comprising: 
            a detection device for capturing a field of view in proximity to the display; and a processor for: 
                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 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; 
                    determining a number of faces of people in the field of view of the detection device; and 
              if the number of faces is greater than a threshold number of users then: 
                blanking the application display on the device display; 
                    displaying an alert on the device display; and 
                    preventing further interaction with the file until the number of faces in the field of view is less than or equal to the threshold number of users.
