CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

Future consumer mobile phone security: a case study using the data centric security model

In the interconnected world that we live in, traditional security barriers are\ud broken down. Developments such as outsourcing, increased usage of mobile\ud devices and wireless networks each cause new security problems.\ud To address the new security threats, a number of solutions have been suggested,\ud mostly aiming at securing data rather than whole systems or networks.\ud However, these visions (such as proposed by the Jericho Forum [9] and IBM\ud [4]) are mostly concerned with large (inter-) enterprise systems. Until now, it is\ud unclear what data-centric security could mean for other systems and environments.\ud One particular category of systems that has been neglected is that of\ud consumer mobile phones. Currently, data security is usually limited to a PIN\ud number on startup and the option to disable wireless connections. The lack of\ud protection does not seem justified, as these devices have steadily increased in\ud capabilities and capacity; they can connect wirelessly to the Internet and have\ud a high risk of being lost or stolen [8]. This not only puts end users at risk, but\ud also their contacts, as phones can contain privacy sensitive data of many others.\ud For example, if birth dates and addresses are kept with the contact records, in\ud many cases a thief will have enough information to impersonate a contact and\ud steal his identity.\ud Could consumer mobile phones benefit from data-centric security? How\ud useful is data-centric security in this context? These are the core questions we\ud will try to address here

Designing mobile augmented reality art applications:addressing the views of the galleries and the artists

The utilization of mobile augmented reality to display gallery artworks or museum content in novel ways is a well-established concept in the augmented reality research community. However, the focus of these systems is generally technologically driven or only addresses the end user and not the views of the gallery or the original artist. In this paper we discuss the design and development of the mobile application ?Taking the Artwork Home?, which allows people to digitally curate their own augmented reality art exhibitions in their own homes by digitally ?replacing? the pictures they have on their walls with content from the Peter Scott Gallery in Lancaster. In particular, we present the insights gained from a research through design methodology that allowed us to consider how the views of the gallery and artists impacted on the system design and therefore the user experience. Thus the final artifact is the result of an iterative evaluation process with over 100 users representing a broad range of demographics and continues to be evaluated/enhanced by observing its operation ?in the wild?. Further, we consider the effect the project has had on gallery practices to enable both augmented reality designers, and galleries and museums to maximize the potential application of the technology when working together on such project

Personal rights management (PRM) : enabling privacy rights in digital online media content

With ubiquitous use of digital camera devices, especially in mobile phones, privacy is no longer threatened by governments and companies only. The new technology creates a new threat by ordinary people, who now have the means to take and distribute pictures of one’s face at no risk and little cost in any situation in public and private spaces. Fast distribution via web based photo albums, online communities and web pages expose an individual’s private life to the public in unpreceeded ways. Social and legal measures are increasingly taken to deal with this problem. In practice however, they lack efficiency, as they are hard to enforce in practice. In this paper, we discuss a supportive infrastructure aiming for the distribution channel; as soon as the picture is publicly available, the exposed individual has a chance to find it and take proper action.Wir stellen ein System zur Wahrnehmung des Rechts am eigenen Bild bei der Veröffentlichung digitaler Fotos, zum Beispiel von Handykameras, im Internet vor. Zur Entdeckung der Veröffentlichung schlagen wir ein Watermarking-Verfahren vor, welches das Auffinden der Bilder durch die potentiell abgebildeten Personen ermöglicht, ohne die Rechte des Fotografen einzuschränken
