Human brain information encryption

In applications like the Metaverse, human brain information can be collected, identified, stored and transmitted with the help of hardware and software systems like brain-computer interface. Not only human personal privacy information can be leaked, but also human behavior and consciousness may be interfered and controlled, which will bring serious information security problems. Therefore, this paper explores the possibility and possible methods of human brain information encryption and protection. First, the definition of human brain information encryption is introduced. Second, possible methods of human brain information encryption and protection at the stages of collection, identification, storage and transmission are proposed. This paper may provide a reference for the future human brain information protection and utilization.
