A Typed Model for Dynamic Authorizations [PDF]
Electronic Proceedings in Theoretical Computer Science, 2016 Security requirements in distributed software systems are inherently dynamic. In the case of authorization policies, resources are meant to be accessed only by authorized parties, but the authorization to access a resource may be dynamically granted ...

Specification and Enforcement of Dynamic Authorization Policies Oriented by Situations [PDF]
2014 6th International Conference on New Technologies, Mobility and Security (NTMS), 2014 Nowadays, accessing communication networks and systems faces multitude applications with large-scale requirements dimensions. Mobility -roaming services in particular- during urgent situations exacerbate the access control issues. Dynamic authorization then is required. However, traditional access control fails to ensure policies to be dynamic. Instead,

Dynamic Authoring of Audio with Linked Scripts [PDF]
Proceedings of the 29th Annual Symposium on User Interface Software and Technology, 2016 Speech recordings are central to modern media from podcasts to audio books to e-lectures and voice-overs. Authoring these recordings involves an iterative back and forth process between script writing/editing and audio recording/editing. Yet, most existing tools treat the script and the audio separately, making the back and forth workflow very tedious.
