Abstract
Nowadays mobile phones include quality photo and video cameras, access to wireless networks and the internet, GPS assistance and other innovative systems. These facilities open them to innovative uses, other than the classical telephonic communication one. Smartphones are a more sophisticated version of classic mobile phones, which have advanced computing power, memory and connectivity. Because fake lithographs are flooding the art market, in this work, we propose a smartphone as simple, robust and efficient sensor for lithograph 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 method for the authentication of stone lithographs. We use the color spots distribution captured by means of a smartphone camera as a non-cloneable texture of the specific artworks and an information management system for verifying it in mobility stone lithography.
Highlights
Mobile phones and smartphones [1] have been increasing their computational power in the last years.These new devices bring together imaging, processing, communication and displaying capabilities
Starting with the possibilities offered by the processing capabilities and performance of the new photo cameras, present in the new smartphones, in this paper we have developed a simple, robust, efficient and low-cost system for lithography authentication
Metadata about the object is stored in association with the digital object identifier (DOI) name and this metadata may include a location, such as a Universal Resource Locator (URL), where the object can be found
Summary
Mobile phones and smartphones [1] have been increasing their computational power in the last years. A legitimate one must contain specific details about the artwork, such as when and how it was produced, the names of people or companies involved in its production, dimensions, and the names of reference books or similar resources that contain either specific or related information about either that work of art and/or the artist It should state the qualifications and full contact information of the individual or entity that authored the certificate, and include his or her complete and current contact information. This digital certificate links information on non-cloneable features of the specific artworks In this way the inappropriate usage will not be possible and the buyer will be able to verify the originality by himself.
