Providing Access Control to Online Photo Albums Based on Tags and Linked Data
Ching Man Au Yeung, Lalana Kagal, Nicholas M. Gibbins, Nigel Shadbolt · 2009
While photo sharing sites such as Flickr provide effi-cient tools for setting up an online album, users who want to maintain a certain level of privacy are usually only provided with rudimentary access control. Given that descriptive tags are extensively used on photos, and that the Semantic Web provides a common means of sharing social network information as linked data, we believe better access control mechanism can be pro-vided by combining the two. Based on this idea, we propose and describe in this paper a system which al-lows users to create expressive access control policies for their photos on the Web by using both tags and linked data.
