People would be happy to enter their information trusting the information network and yet, all the provided personal information has been leaked out, and any advertising information is being sent and received recklessly in various ways. From now on, such promotions should be performed only extensively via various media such as TV, radio, the internet and others. The government or other related fields should choose a medium which would satisfy the purpose most satisfactorily as they carefully look into features of each medium. Not only that, making good use of the Internet only actively, those in charge of privacy protection are advised to approach people with a new way to promote relevant campaigns, setting up two-way communication channel with people. In conclusion, once the government, companies and people voluntarily cooperate on the promotion of privacy protection with the greatest passion, we will soon open an era in which personal information is protected no matter what in daily life.
