On ilmunud siis verivärske turvaõpetus ja ehk kellelgi on sellest kasu selles "karmils rünnatavas - häkitavas netimaailmas":

Remove metadata from Office files, PDFs, and images
Make sure you're not communicating more than you intend to when sharing files and uploading images by excising some of the data about your data.

Your metadata says a lot about you. When I ran 10 years of Gmail messages through MIT Media Labs' Immersion email metadata visualization tool, the resulting image (shown above) predicted relationships with my frequent correspondents with uncanny accuracy.

Immersion scans only the From, To, Cc, and Timestamp fields of messages in Gmail, Yahoo Mail, or MSExchange. A scan of my Gmail account indicated I have received more than 50,000 messages in the 10.1 years I've used the service. Immersion identified 189 collaborators, and it predicted how many new collaborators I would have this year, as well as the number of messages I would send and receive through the rest of 2014.
