Method to quantify the security level of personal information

There are many tools that scan a personal computer (pc) to determine whether the pc stores some personal information. Typically, such tools scan all files in the pc and output a list of files that possibly contain some personal information (e.g., a pair of name and e-mail address) as the detection result.

However, it is often the case that, due to the incomplete accuracy, the listed files contain no personal information. For example, when you scan your web cache files, such tools tend to list a number of files, but they tend to contain no personal information. So the listed files do not always contain critical personal information like a list of your customer's email addresses. As a result, eventually you need to manually determine which file really contains personal information among the listed files. It tends to be very costly. Therefore, it is important to quantify the security level of personal information to reduce the cost of the manual work. That is, if the listed files are sorted by the security level, then the determination work will be much easier.

We propose to make use of general-purpose search engines publicly available on the Internet. Examples include Yahoo and Google. Specifically, we perform a search using the detected personal information (e.g., a pair of name and e-mail address) as the key word, and we consider the reciprocal of the number of the search results as the security level....
