Vie privée et métadonnées
Pour la prochaine fois où on vous dit « Oh mais on récupère que les métadonnées, et pas le contenu de vos appels, rien à craindre ! ».
Metadata about your phone calls can give away some very intimate and sensitive information. For example:
They know you rang a phone sex service at 2:24 am and spoke for 18 minutes, but they don’t know what you talked about.
They know you called the suicide prevention hotline from the Golden Gate Bridge, but the topic of the call remains a secret.
They know you spoke with an HIV testing service, then your doctor, then your health insurance company in the same hour, but they don’t know what was discussed.
They know you received a call from the local NRA office while it was having a campaign against gun legislation, and then called your senators and congressional representatives immediately after, but the content of those calls remains safe from government intrusion.
They know you called a gynecologist, spoke for a half hour, and then called the local Planned Parenthood’s number later that day, but nobody knows what you spoke about.
