サービス提供者がユーザのパーソナルデータを収集する際には、

ポリシーを提示し、事前にユーザの同意を得るという仕組みは世の中に普及していると言われて久しい。一方で、ユーザはポリシーを読んでいない、またはポリシーはユーザにとって難解であるという指摘もされている。我々は、機械学習を利用して、ユーザがポリシーを理解するための支援ツールの構築を検討している。本稿では、ポリシーの固有表現の曖昧性と情報量により、国内外の企業が提供しているウェブサイトのポリシーを分類する。ポリシーを分類した結果により、我々が構築するポリシーのユーザ理解支援ツールの適用先となるポリシーの特徴と、ポリシーにおける透明性について考察する。

The present study examined the relationship between concern about privacy and apprehension of the word “privacy.” A web-based survey was conducted with 221 Internet users about how the respondents considered the word “privacy” using an open-ended question. The results indicated that respondents mainly considered the word “privacy” as referring to “personal information” or “secret”. A chi-squared test showed that the proportion of respondents who considered privacy as a “personal boundary” was greater among those who were more concerned about privacy. Moreover, the proportion of respondents who considered privacy as “secret” was greater among those who were less concerned about privacy.

We investigate privacy-related problems in community pharmacies in an attempt to create an appropriate environment for information sharing between patients and medical workers in medical services. For this purpose, we conducted onsite investigations at 74 community pharmacies and telephone interviews with the pharmacists of 10 community pharmacies. At the site visits, an investigator interviewed pharmacists to determine how the lack of speech privacy affects patient counseling. In addition, a psychological experiment was performed to assess whether the investigator sitting in the patient waiting area could hear the conversation between a patient and a pharmacist. At 80% of the pharmacies, privacy protection for every patient was a priority. There were 77 instances of privacy problems or privacy-related claims, at 39% of the community pharmacies. The results of the experiment show that patient-pharmacist conversations can be overheard in the patient waiting area at 70% of the community pharmacies. The causes of privacy-related problems were physical environment (speech privacy), the social role of the pharmacist, and complex mechanisms like information-sharing practices within the medical system. These factors seem to influence each other, making it difficult to improve patient-centered care.
