Many graph mining and analysis services have been deployed on the cloud, including Neo4j, GraphDB, Dydra, Infinity Graph, GraphLab, System G, to name a few. Cloud based graph analytics can alleviate users from the burden of implementing and maintaining graph algorithms. However, it invades the security and privacy of users' graph data. To solve this problem, we propose CryptGraph, which runs graph analytics on encrypted graph... Read More
