オンライン会議アプリ「Zoom」は人々のリモートワークの移行に伴い利用されるようになっていきましたが、ユーザーの許可なくカメラが有効化される脆弱性や、OSの資格情報を盗まれる脆弱性、Facebookアカウントを持っていないユーザーであってもデータをFacebookに送信されてしまうことなど、数々の問題が指摘されています。このような状況を受けて、Googleは従業員に対し、ZoomアプリをインストールしたノートPCをリモート環境で使うことを禁止しました。 Google Bans Zoom Videoconferencing Software From Employees' Computers https://www.buzzfeednews.com/article/pranavdixit/google-bans-zoom ビデオ会議サービス「Zoom」は2019年に上場したアメリカ・カリフォ
ビデオ会議や音声チャットの途中で諸用を済ませるために一時的に離席する時、余計な音声が相手に届かないようにマイクをミュートにすることがあります。しかし、「ビデオ会議中にマイクをミュートにすると、たとえ相手に音声は届かなくても、アプリ自体は音声データを収集している」と、ウィスコンシン大学電気・コンピューター工学科のカッセム・ファワズ助教の研究チームが発表しました。 Are You Really Muted?: A Privacy Analysis of Mute Buttons in Video Conferencing Apps (PDFファイル)https://wiscprivacy.com/papers/vca_mute.pdf You’re muted — or are you?

You’re muted — or are you? Videoconferencing apps may listen even when mic is off UW–Madison engineering professor Kassem Favaz (left) and graduate student Yucheng Yang analyzed the way popular video conferencing apps collect data, finding that at least one appears to collect all the audio from a user’s microphone even when “muted.” Contributed photo Kassem Fawaz’s brother was on a videoconference
COVID-19 accelerated a decade-long shift to remote work by normalizing working from home on a large scale. Indeed, 75% of US employees in a 2021 survey reported a personal preference for working remotely at least one day per week1, and studies estimate that 20% of US workdays will take place at home after the pandemic ends2. Here we examine how this shift away from in-person interaction affects in

ビデオ会議アプリはミュート中も音声を収集している？
新型コロナウイルス感染症の影響で、テレワークが一般的なビジネスシーンになった。テレワークをスムーズに進める方法の一つがビデオ会議だが、もしかするとそのビデオ会議システムはマイクをミュートにしている間も音声データの収集を行っているかもしれない。大学の研究者らが調査の結果、ビデオ会議アプリはミュート中もマイクへのアクセスを放棄しておらず、音声データの収集を行っていると指摘したのだ。 ウィスコンシン大学マディソン校(University of Wisconsin-Madison)の研究者らがこのほど、「You’re muted — or are you?
