PhD Project in Security and Privacy in Managed Video Systems

Deadline: 1st August 2012

Nationality: Any

How to Apply.

DTU Informatics would like to invite applications for a 3-year PhD position starting September 1 2012 or as soon as possible hereafter. The project is financed by an Advanced Technology Foundation grant and DTU Informatics, and is part of the Managed Video as a Service (MVaaS) project.

Project Description
Development of a distributed storage architecture which provides the necessary services to support resource management, dynamic reconfiguration and fault tolerance. The resource management includes dynamic scheduling of communication channels and video storage subsystems and a naming-/location service that allows for recovery of stored video streams. Dynamic reconfiguration must support continuous operation despite physical system components being added, removed or reassigned. This will be supported by the naming-/location service that maps logical video stream identifiers to the partial video streams that are stored on different storage subsystems. In order to achieve these objectives, the following topics have to be addressed:

1. Design and implementation distributed storage architecture for video data and the associated metadata. The storage subsystems to be incorporated in the architecture will be very diverse ranging from local hard disks to the cloud.
2. Development of scheduling algorithms that map video streams and the associated metadata to the underlying infrastructure.
3. The introduction of a logical video stream abstraction that supports dynamic relocation of video stream segments on different storage subsystems.
4. Support access control mechanisms and indexing and searching metadata in the distributed architecture.

Requirements
Candidates must have a master degree in computer science, computational science and engineering (CSE), applied mathematics, or engineering, or equivalent academic qualifications. Preference will be given to candidates who can document experience with distributed storage architectures and the related scheduling algorithms, and in addition have a background in data security (access control) or data indexing. Furthermore, good command of the English language is essential.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in the ITMAN Graduate School Programme of DTU Informatics. Information about the general requirements for enrolment and the general planning of the scholarship studies is included in the general rules at DTU, which may be obtained here.

Salary and appointment terms
The salary and appointment terms are consistent with the current Danish rules for PhD degree students.
