Share Me - A digital annotation sharing service for paper documents with multiple clients support

In this paper we describe a novel annotation service which is capable of seamlessly linking physical and digital worlds through paper documents. Our service uses a real-time document image retrieval method called Locally Likely Arrangement Hashing (LLAH) for providing information associated with the document. By using this service digital annotations can be added to physical documents and shared with friends via mobile devices. We present the prototype implementation, and provide a discussion covering the technical details of the system.
