<p>Artwork counterfeiting is a wide problem in the art market, both for private subject and museums. For this reason, it is important introducing innovative authentication solutions, based on state-of-the-art technologies. In particular, in this paper, the proposed solution is based on a mobile architecture, starting from the consideration that nowadays mobile phones include quality photo and video cameras, access to wireless networks and the internet, GPS assistance and other innovative systems. The proposed solution uses smartphones as simple, robust and efficient sensor for artworks authentication. When we buy an artwork object, the seller issues a certificate of authenticity, which contains specific details about the artwork itself. Unscrupulous sellers can duplicate the classic certificates of authenticity, and then use them to “authenticate” non-genuine works of art. In this way, the buyer will have a copy of an original certificate to attest that the “not original artwork” is an original one. A solution for this problem would be to insert a system that links together the certificate and the related specific artwork. To do this it is necessary, for a single artwork, to find unique, unrepeatable, and unchangeable characteristics. In this article we propose an innovative and not-invasive method for the authentication of artworks based on random intrinsic object characteristics. This approach is based on biometry paradigm (analogue fingerprinting). The paper present a stand-alone solution, and an internet-based one, necessary for granting security verification also in case of problem with the used RFID tag. The proposed method uses an RFID Tag and a 2D barcode, in conjunction with an Internet-based Authentication Archive.</p>

In the present study we link self-report-data on personality to behavior recorded on the mobile phone. This new approach from Psychoinformatics collects data from humans in everyday life. It demonstrates the fruitful collaboration between psychology and computer science, combining Big Data with psychological variables. Given the large number of variables, which can be tracked on a smartphone, the present study focuses on the traditional features of mobile phones – namely incoming and outgoing calls and SMS. We observed N = 49 participants with respect to the telephone/SMS usage via our custom developed mobile phone app for 5 weeks. Extraversion was positively associated with nearly all related telephone call variables. In particular, Extraverts directly reach out to their social network via voice calls.

The purpose of this study is to examine the effect of prestige sensitivity on mobile phone customer’s price acceptance in Vietnam and the mediating role of product knowledge and price mavenism on this relationship. We used the convenience sampling method for data collection via questionnaires with a sample of 605 consumers who purchased mobile phones. The collected data was analysed by applying a structural equation modelling method. The result indicates that prestige sensitivity has both direct and indirect effects on price acceptance via product knowledge and price mavenism. The findings suggest that prestige sensitivity can be used as a market segmentation criterion for mobile phones when making price decisions and providing customers with adequate information could improve price acceptance.
