Abstract
Nowadays, it is easier to share the information in a large framework compared with the past, as for it, the numbers of discussions are rising extremely. First, I will reconsider to organize information and privacy and their handling in Modern. Thereby, the concept of privacy in modem Japanese society, I described that is based on the self-information control rights. And, as a means of self-information control rights, I consider phased information disclosure techniques. It is about increasing the power of self-information control rights of the data subject by phased information disclosure as much as possible keeping concealment of personal identification.
