Providing Access Control to Online Photo Albums Based on Tags and Linked Data

Ching-man Au Yeung, Lalana Kagal, Nicholas Gibbins, Nigel Shadbolt

While photo sharing sites such as Flickr provide efficient 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 provided by combining the two. Based on this idea, we propose and describe in this paper a system which allows users to create expressive access control policies for their photos on the Web by using both tags and linked data.
