Abstract:
Big Data and Machine Learning have been a new phenomenon that finds its way to impact many aspects of modern informatics. The speed and degree with which this impact brought the advancement upon modern technology has been unprecedented. Parallel to other fields, the implication of Bid Data and Machine learning in medicine in terms of diagnosis and treatment has gradually gained attention and the new dynamics of development has been clearly underway. Historically, good medicine relies on two indispensible pillars, human experience and instrumentation. While industrial technology continuing to push the envelop of advancing the modern medical instrumentation, the Bid Data and Machine Learning emerged as an unexpected ¡°gift¡± that reveals unusual ability of elevating cumulative knowledge in terms of human intervention to a whole new level. In this presentation we will use radiation cancer therapy as an example to discuss how machine learning could advance the quality of cancer treatment. In the standard practice of radiation oncology, physicians and medical physicists analyze each patient¡¯s disease with respects to the type, size and anatomic location to design an ¡°optimal¡± plan that would yield most desirable outcome. In this aspect, human factor in terms of experience plays a crucial role in determining the clinical outcome. Using knowledge-based machine learning technology, cumulative human experience could be leveraged to produce an optimal plan consistently, reliably and efficiently. The development of such technology is still in its infancy and the application has not been widely available, appreciated and assimilated. It is with supreme confidence that the presenter anticipates a most optimistic future of the application of Bid Data/Machine in modern medicine.

Searchable Symmetric Encryption: Potential Attacks, Practical Constructions and Extensions

Dr. Jinjun Chen
University of Technology Sydney (UTS), Australia

Abstract:
Data outsourcing has become one of the most successful applications of cloud computing, as it significantly reduces data owners' costs on data storage and management. To prevent privacy disclosure, sensitive data has to be encrypted before outsourcing. Traditional encryption tools such as AES, however, destroy the data searchability because keyword searches cannot be performed over encrypted data. Though the above issue has been addressed by an advanced cryptographic primitive, called searchable symmetric encryption (SSE), we observe that existing SSE schemes still suffer security, efficiency or functionality flaws. In this research, we further study SSE on three aspects. Firstly, we address the search pattern leakage issue. We demonstrate that potential attacks are exist as long as an adversary with some background knowledge learns users' search pattern. We then develop a general countermeasure to transform an existing SSE scheme to a new scheme where the search pattern is hidden. Secondly, motivated by the practical phenomenon in data outsourcing scenarios that user data is distributed over multiple data sources, we propose efficient SSE constructions which allow each data source to build a local index individually and enable the storage provider to merge all local indexes into a global one. Thirdly, we extend SSE into graph encryption with support for specific graph queries. E.g., we investigate how to perform shortest distance queries on an encrypted graph.
