Research Summary

Along with the development of artificial intelligence (AI) technologies, decision making by machine learning is being widely implemented in society. In order for artificial intelligence to play a prominent role in decision making of humans, it is necessary to guarantee that private or confidential information is not leaked through the process of decision making　by AI. Also, we need guarantee that that AI's behavior cannot be arbitrarily manipulated by a malicious attacker and AI cannot harm humans against the original AI designers’ intent. Our team aims to develop fundamental technologies of security and privacy that are necessary for proper use of AI in society.
