TOKYO -- While Japan's recent efforts to beef up active cyberdefense have raised public concerns, the government must "take steps to protect society, even at the cost of some limited invasion of privacy," U.K. Investigatory Powers Commissioner Brian Leveson, a retired High Court judge, told Nikkei in a recent interview.
Leveson heads an independent body that oversees the use of investigatory powers by police and intelligence agencies, such as warrants for surveillance. Japan plans to create a similar body to monitor the government's cyberdefense activities.
