A computer that can read people's minds

Some people are afraid of the technology in which computer can read people’s minds. They fear that in this situation, privacy is stolen. Thus, this mapping skill makes them feel unsafe. In my opinion, this technology should not be used by evil purposes, say unfairness in employment or stealing of privacy. In order to minimize the potential unethical abuses of my work, I think we should regulate three groups, namely how much screening is allowed, who has such an access to others’ mind, what will happen if the modification is made.
Firstly, I think scanning should not be used to detect people’s privacy. We can only use this technology to scan cancers of patients or under police permission to detect potential criminals. Further scanning of brain should base on both sides’ approval. In this way, scanning is fair and ethical. Secondly, it is important to decide who has the access to others’ minds. Scientist, doctors and police can, but they should get the permission of people who are scanned, except that it is for forensic purposes. Thirdly, by knowing how brain works, we may probably know how to modify different parts in brains so to let it function as we wish; and we must know the consequences that if the modification is made, like whether it dose harm to the patient or not. We can use this technology to cure the cancer cells and activate the dead or disabled brain cells; or we can heal mental disorders which are hard for conventional treatments to function well. However, it is not moral to apply this technology to a mentally good people. They can think, speak and live properly. They can determine independently about whether they need such modifications or not, or how much the treatments are put into use. Under this situation, they are the one to decide what consequences will come about.
In conclusion, we should use this scanning technology properly and wisely, most importantly, to use it morally.
