Access Control Based on Code Identity for Open Distributed Systems

In computing systems, trust is an expectation on the dynamic behavior of an agent; static analysis is a collection of techniques for establishing static bounds on the dynamic behavior of an agent. We study the relationship between code identity, static analysis and trust in open distributed systems. Our primary result is a robust safety theorem expressed in terms of a distributed higher-order p...

QR Code Steganography

QR codes, also known as matrix codes, are basically two dimensional barcodes embedded with data that can be decoded quickly for information. In this work, we present a novel use of QR codes. We show that QR codes can be used for covert communication using steganography. We also show in complete detail how to build QR code symbols with a hidden payload and how to extract this hidden information ...

Artistic QR Code Embellishment

A QR code is a two-dimensional barcode that encodes information. A standard QR code contains only regular black and white squares, and thus is unattractive. This paper proposes a novel framework for embellishing a standard QR code, to make it both attractive and recognizable by any human while maintaining its scanability. The proposed method is inspired by artistic methods. A QR code is typical...
