## Controversy

On 26 December 2013, the Japanese government's National Information Security Center (NISC) and Ministry of Education, Culture, Science and Technology advised 140 institutions to either disable the cloud-input function of Baidu Input Method Editors (IMEs) or stop using Baidu IMEs. According to Bloomberg News, Tsuneo Tosaka, IDC Japan's Software & Security Research Manager claimed: "Baidu provides the service using a cloud server, which means content flows through servers in China" and "Government-related documents from Japan central ministries and findings from university research institutions are important, so there is a possibility that sensitive information leaks abroad." NISC also suggested not using Google input software and Microsoft input software.
