Abstract

Compact face photographs, stored and digitally signed in 2D barcodes, form a low-cost tamper-resistant identity credential. The cryptographic signature allows binding of the 2D barcode to the issuer, and bio- metric authentication binds a live photograph of the user to the photo stored in the barcode. This report documents options for the detection, cropping, resizing, and compression steps needed to instantiate a barcode-ready photograph. The compression step is necessarily lossy, removing fine spatial structure from the face photograph. The report documents the accuracy consequences, with the overall result that fully open standards-based compact faces can be verified with very high accuracy.
