How does the willingness to provide private information change?

With the arrival of "Big Data use" era, user information is collected and gathered by service providers. Because this information includes sensitive and private information, users sometimes feel their privacy is invaded. It is difficult to make a unique range of privacy. Instead of investigating the concrete range of privacy, we survey users' opposition to disclose each information. In this paper, we first examined the information users oppose having collected. Then, we examined the conditions in which users oppose having their information collected. Based on the results of study in this paper, we present numerical data that expresses the users' opposition to provide their data, as of 2015 in Japan. Fortunately, an exact framework and technology to prevent privacy invasion is not constructed, we have been left room for reflecting users' oppositions on new framework or technology to be made from now on. So, it is important to understand the users' oppositions to be collected their information. These results provide us with a helpful information in collecting and analyzing large-volume data.
