ITCSC-INC Winter School App

Scanner app for the ITCSC-INC Winter School to decode Authenticated QR codes

This is a scanner application created for the ITCSC-INC Winter School 2015 to decode and verify Authenticated QR codes on the name badges. Created by MobiTeC, The Chinese University of Hong Kong, this scanner can also decode AuthPapers from http://www.authpaper.net and normal 2D barcodes.

AuthPaper (Authenticated Papers) provides an offline, cost-effective, secure solution for authenticating paper-based documents/credentials using off-the-shelf handheld devices such as smartphones and tablets.

The key idea is to extend existing 2D barcodes, e.g. the QR-code, to carry a large amount of self-describing, and most importantly, authenticated data of all types containing text, image as well as other binary ones. By embedding the Authenticated 2D Barcode as an integral part of a paper-based document, the authenticity of the document can be readily verified by comparing its content with the corresponding digitally-signed content contained in the Authenticated 2D Barcode.

The code verification process does not need the access of the Internet. The only reason of declaring the Internet permission is to collect usage statistics.

At the first time you open the App, we will get your email address and hardware details for statistics purpose and to verify that this application is installed via Google Play.

We will also collect some information anonymously on each successful scanning (scanning time, size of scanned QR code, number of frames taken, etc.) for usage statistics purpose, but the privacy information like QR code contents, camera images and user information are not collected.

You may also disable the data collection in the setting page.

Project details and the AuthPaper creation service are available on http://www.authpaper.net

If you find any problem, please inform us.

The AuthPaper research project is supported in part by grants from the Innovation and Technology Fund (ITF) of the Hong Kong SAR Government (Project no. ITS/300/13) and the Technology and Business Development Fund (TBF) of the Chinese University of Hong Kong (Project code TBF14ENG004).
