“…Their purpose was to camouflage the appearance of a QR code in an image so as not to degrade the visual quality of the picture. Huang et al [12] developed a reversible data hiding approach for images with QR codes. The purpose of their method was to avoid a QR code from degrading the quality of the image or concealing information contained in the image.…”

This paper investigates a novel approach to secret sharing using QR codes. The proposed QR code secret sharing approach exploits the error correction mechanism inherent in the QR code structure, to distribute and encode information about a secret message in a number of shares. Each share in the scheme is constructed from a cover QR code, and each share itself is a valid QR code which can be scanned and decoded by a QR code reader. The secret message can be recovered by combining the information contained in the QR code shares. Since each share is a valid QR code, the proposed scheme has the advantage of reducing the likelihood of attracting the attention of potential attackers. In addition, the shares can be distributed via public channels without raising suspicion. Moreover, shares do not have to be stored or transmitted electronically, as QR codes can be distributed via printed media. Abstract.

Abstract. Personal mobile devices with real practical computational power and Internet connectivity are currently widespread throughout all levels of society. This is so much so that the most popular of these devices, the smart phone, in all its varied ubiquitous manifestations is nowadays the de facto personal mobile computing platform, be it for civil or even military applications. In parallel with these developments, Internet application providers like Google and Facebook are developing and deploying an ever increasing set of personal services that are being aggregated and structured over personal user accounts were an ever increasing set of personal private sensitive attributes is being massively aggregated. In this paper we describe OFELIA (Open Federated Environment for Leveraging of Identity and Authorization), a framework for user centric identity management that provides an identity/authorization versatile infrastructure that does not depend upon the massive aggregation of users identity attributes to offer a versatile set of identity services. In OFELIA personal attributes are distributed among and protected by several otherwise unrelated AAs (Attribute Authorities). Only the user mobile device knows how to aggregate these scattered AAs identity attributes back into some useful identifiable entity identity. Moreover by recurring to an IdB (Identity Broker), acting as a privacy enhancing blind caching-proxy, in OFELIA the identity attributes location in the Internet is hidden from the RP/SP (Relying Party, Service Provider) that wants to have temporary access to the users personal data. The mobile device thus becomes the means by which the user can asynchronously exercise discretionary access control over their most sensitive dynamic identity attributes in a simple but highly transparent way.
