    Publication . Serrão, Carlos; Marques, Joaquim
    This paper describes the usage of specific web application designed for the Electronic Commerce of Digital Still Images using some of the state-of-the-art technologies in the field of digital imaging, namely copy right protection. Still images are not only traded using this platform but also value is added to the images through the means of cataloguing, metadata and watermark insertion. This work is performed using some auxiliary tools, which are also referred in the present paper. This paper also proposes and discusses a methodology for streamlining the production of still digital image content. The methodology proposed and described here, called DIGIPIPE, encompasses several steps which range from the simple image digitalization until the image trading, without omitting the image copy rights protection procedures.

  • Rights management on knowledge-based digital content
    Publication . Serrão, Carlos; Marques, Joaquim; Mendes, Ana
    The digital networks have facilitated the digital content access and sharing. Although this creates the opportunities to a wider dissemination of information and knowledge, on the other hand it creates challenges on what concerns the protection and enforcement of Intellectual Property (IP). This is particular important on the IP management of digital knowledge-based that is create on a daily basis on educational and research institutions, where a set of researchers and educators contribute with their knowledge creation works to the education value-adding processes. This paper will address the different scenarios/stages where the application of rights management solutions to the protection and management of knowledge-based content can provide an appropriate management of IP. These scenarios will consider the production and protection of the content, the rights establishment for the dissemination of content and the appropriate IP enforcement on the content user-side. This would establish a global environment where knowledge-based content IPR can be governed, allowing authors to establish the conditions that allow others to use their own work.
