Where technology & law meet: Open Access research on data security & its regulation ...

Strathprints makes available Open Access scholarly outputs exploring both the technical aspects of computer security, but also the regulation of existing or emerging technologies. A research specialism of the Department of Computer & Information Sciences (CIS) is computer security. Researchers explore issues surrounding web intrusion detection techniques, malware characteristics, textual steganography and trusted systems. Digital forensics and cyber crime are also a focus.

Meanwhile, the School of Law and its Centre for Internet Law & Policy undertake studies on Internet governance. An important component of this work is consideration of privacy and data protection questions and the increasing focus on cybercrime and 'cyberterrorism'.

Abstract

Visual inspection is an integral part of Condition and Class surveys, with the results comprising of the surveyors’ opinion, documented by a sum of pictures indicating areas of interest. Although this way provides the most essential information, the communication of the results may be difficult, since isolated images cannot provide the context. Photogrammetry exploits pictorial data to provide 3D models, with a high level of accuracy and is not an uncommon method in the maritime environment. Use of such methods to support visual survey activities is examined in this work, providing the methodology for the data collection, which is structured in an algorithmic way, to enable realization by automated means (robots). The 3D model is provided, along with accuracy results.
