Title: Privacy Preserving Problems in Big Data Query Processing
Abstract: The need to efficiently store and query large scale datasets is evident in the growing number of data-intensive applications, particularly to maximize the mining of intelligence from these data (e.g., to inform decision making). However, directly releasing dataset for analysis may leak sensitive information of an individual even if the data is anonymized, as demonstrated by the re-identification attacks on the DBpedia datasets. In this talk, we introduce a novel k-decomposition algorithm and define a new information loss matrix designed for utility measurement in massively large graph datasets. We also propose a novel privacy preserving framework that can be seamlessly integrated with graph storage, anonymization, query processing, and analysis.

Title: The use of Extended Reality (XR) in Education: To Implement or Not To Implement
Abstract: The use of Extended Reality (XR) in education has been gaining popularity in recent years due to its potential to enhance learning outcomes, engagement, and efficiency. However, there are also concerns regarding the potential negative impact on social interaction, accessibility, and privacy. This keynote speech discusses the pros and cons of XR in education and identifies factors that need to be considered before implementing it. These include the purpose and goals of integrating XR, availability of resources and infrastructure, teacher training and support, ethical and privacy considerations, and potential impact on learners and society. Educators and policymakers need to carefully weigh the potential benefits and risks of XR in education to make informed decisions about its implementation.
