To obtain data on human education, employers need to obtain a code of access to this information. In future use of this code the information will not be changed automatically to avoid interference in the reliability of information? After all, this code should have only the owner of this certificate.
Very interesting question. In this process there should be a guarantee that only one participant will own the information. And that without his permission no one had access to personal information. But I am sure that this issue will be taken into account in the development of the protection program.
