This sounds promising! Recently in Japan, researchers have been able to attach some kind of sensor on an affordable headset, which supposedly allows mind reading and thought transfer. It was reported by a website - which publishes news about software, Internet and as well nanotechnology - that some tests have already been taken into consideration for their headset's safety guard. In this way, it's possible to maintain and read streams of thoughts with a sensor, whose specific function is not clear yet. For example, passwords can be dialled by thoughts, which enables a new and viable login option.
Their sensor has already been checked during some test runs, which proceeded successfully. Testers had to concentrate on different actions, like frequent breathing or even singing in thought. The error rate was very low. In more than 99% of all cases, no more than 1 sensor attached on the headset was needed to work properly; usually more sensors are used for tests like that.
According to phys.org, it's possible to identify users via thoughts with the help of a headset, which doesn't cost a fortune - this might not be distant future anymore, but become reality.
