Abstract
Disclosed is detecting identification documents in images (image-borne identification documents) and protecting against loss of the image-borne identification documents—training a DL stack by forward inference and back propagation using labelled ground truth data for the image-borne identification documents and the examples of other image documents. The DL stack includes a first set of layers closer to an input layer and a second set of layers further from the input layer, the first set of layers being pre-trained to perform image recognition before exposing the second layer of the DL stack to the labelled ground truth data for the image-borne identification documents and the examples of other image documents. Also included is storing parameters of the trained DL stack for inference from production images, and using a production DL stack with the stored parameters to classify at least one production image by inference as containing a sensitive image-borne identification document.
