title: Secure Cloud-based Imaging
Today resource intensive tasks such as storage and processing of huge amount of multimedia data (in applications like video surveillance, social networks and e-health) are being outsourced to Cloud Data Centers (CDCs). However, since CDCs are generally third party entities, there is always a risk of data security and privacy. In this talk, we will discuss a secure cloud-based multimedia computing framework, in which we encrypt the data before sending to the cloud. To overcome the problem of processing the encrypted data over cloud, we employ cryptographic secret sharing technique which possesses homomorphism property and allows encrypted domain processing of data over cloud. We examine the suitability of the proposed framework for encrypted domain cloud-based processing of 3D medical images for remote visualization and of surveillance images for quality enhancement. We believe that this framework can be used in many other applications which require processing/storing the data over cloud in a secure and private manner.

title: An Ethnography of Robot Therapy in a Manitoba Care Home
Dr. Sheelagh CarpendaleWhen: February 13, 2014 @ 1:00pm
Where: EITC E2-304
Speaker: Sheelagh Carpendale, Department of Computer Science, University of Calgary
Dr. Sheelagh Carpendale is an full professor in theat the . Her research interests include information visualization, user interface design, human-computer interaction, visual languages and graph layout.
Though her current professional focus is computing science she has a background in both arts and sciences. She left high school with science scholarships but instead initially opted for fine arts, attendingand . For ten years she worked professionally in the arts. During this time she taught at and was involved in establishing the at York Quay, in Toronto. Subsequently she has reconnected with her interests in math and science by studying computing science at . She has found the combined visual arts and computing science background invaluable in her information visualization research.
Previously she was a Research Associate with the(Simulating and Exploring Ecosystem Dynamics) project. This research took place in the in the at was funded by . The purpose of SEED project is to create a suite of tools for assisting the process of building and running spatially explicit models of landscape dynamics, and for exploring, visualizing and analyzing the results of such simulations.
Dr. John BateWhen: February 20, 2014 @ 1:00pm
speaker: John Bate, Department of Computer Science, University of British Columbia
title: Efficient Isomorphism Detection in Searches
Searching efficiently for combinatorial objects requires the elimination of isomorphic configurations, either during the search process itself, or from the results generated. Graph isomorphism methods are used to do this, and there is little room for improvement in the existing algorithms, when applied to individual graphs. However, a method will be presented which can significantly improve their efficiency when applied to large sets of graphs.
I will give a general introduction to the graph isomorphism problem, and a broad outline of the methods used by traditional algorithms in this area, followed by the enhancement for processing large sets of graphs.
