1. A method, comprising: capturing, by a computing device, an image including at least a face of a user; calculating, by the computing device, a face template of the face of the user in the image; analyzing, by the computing device, the face template to determine whether the face includes at least one of a removable facial feature that decreases a level of distinctiveness between two faces and a non-removable facial feature that decreases a level of distinctiveness between two faces, wherein analyzing the face template to determine whether the face includes the removable facial feature that decreases the level of distinctiveness between two faces further comprises: determining, by the computing device, a plurality of removable facial feature similarity scores between the face template and one or more removable facial feature templates; and calculating, by the computing device, a weighted sum of the plurality of removable facial feature similarity scores, wherein when the weighted sum of the plurality of removable facial feature similarity scores is positive, determining that the face includes the removable facial feature, and wherein when the weighted sum of the plurality of removable facial feature similarity scores is negative, determining that the face does not include the removable facial feature, when the face includes the removable facial feature, the method comprises: outputting, by the computing device, a notification for the user to remove the removable facial feature; and when the face includes the non-removable facial feature, the method comprises: adjusting, by the computing device, a first similarity score threshold to a second similarity score threshold.
