讲座摘要：

Privacy preserving graph similarity search

Graph similarity search is a fundamental problem in graph data analysis. However, preserving the privacy of graphs during the similarity search is challenging. First, graph similarity search is NP-hard. The pruning techniques, which is critical for the efficiency in non-private graph similarity search methods could leak the privacy of graphs. Second, due to the regulations or business concerns, the owners of graph data may not be able to share their data directly. They have to collaborate in a federated manner, where the original data does not leave each data owner. However, the network access pattern during the collaborated searching could leak the privacy of graph data. In the past years, we have investigated several techniques to address the two technical challenges, which will be presented in this sharing.
