Now, it's a data society for progress of ICT and AI.We can receive convenient service that like E-commerce,SNS,health management,etc.It's makes it possible to buy everything everywhere and connect people all over the world and get down our medical cost.It's good movement. But on the other hand,it includes many risk about personal data that is ME itself.When we want to receive convenient service, we have to expose our personal data to company.It's not only name and address,but also what kind of things you bought before,what kind of friends that you have,what kind of health problem that you have in the future.And exposed personal data leave US, then bundle company and company.After that many personal data make to reconstruct US.It begin to get influence about value of people, finance,work,education.So now the time we think about data society balance of convenience and risk.Data cross the border,but don't progress making international rule.I research in US that developed country of data use,then think and report about necessity of international rule making.
