データ不当利用、独禁法違反の恐れ　デジタル広告規制へ最終報告―公取委

　公正取引委員会は１７日、デジタル広告規制をめぐる実態調査の最終報告を公表した。有力な広告媒体・配信機能を持つ米グーグルなど巨大ＩＴによる個人データの不当利用や取引先との一方的な契約変更は、独禁法が禁じる「優越的地位の乱用」に当たる恐れがあると警告。政府は今後、最終報告などを基に広告分野での規制の具体化を急ぐ。

Japan's Fair Trade Commission warned in a report Wednesday that information technology giants' inappropriate use of personal data and unilateral changes in terms of contracts with partners in the digital advertising business may constitute an abuse of their dominant bargaining position, banned under the antimonopoly law.
   The antimonopoly watchdog's final report on its fact-finding survey in the digital ad field marks the beginning of the government's work to regulate IT giants, such as Google LLC of the United States, in the field.
   According to the survey results, some platforms for targeted ads use such personal data as location information despite user settings to prevent their website search history from being tracked.
   Unless sufficient explanations are given to consumers, such a practice will be regarded as obtaining personal information in an inappropriate way, the FTC clarified in the report.
   The commission also warned IT mammoths of the possibility of being charged for violating the law if they cause detriment to digital ad sponsors and website operators by taking advantage of their "dominant position."
