Schützen Sie Ihre Identität, wenn Sie Tails nutzen
Löschen Sie die Metadaten von Dateien, bevor Sie diese teilen
Viele Dateien beinhalten versteckte Daten oder Metadaten:
JPEG und andere Bilddateiformate beinhalten oftmals Informationen darüber, wo ein Bild aufgenommen wurde und welche Kamera benutzt wurde.
Office-Dokumente beinhalten oftmals Informationen über den Autor, das Datum und die Uhrzeit, wann das Dokument erstellt wurde.
To help you clean metadata, Tails include Metadata Cleaner, a tool to remove metadata in a wide range of file formats.
Metadata has been used in the past to locate people from pictures they took. For an example, see NPR: Betrayed by metadata, John McAfee admits he's really in Guatemala.
Use Tails sessions for only one purpose at a time
If you use Tails sessions for more than one purpose at a time, an adversary could link your different activities together.
For example, if you log into different accounts on the same website in a single Tails session, the website could determine that the accounts are used by the same person. This is because websites can tell when 2 accounts are using the same Tor circuit.
To prevent an adversary from linking your activities together while using Tails, restart Tails between different activities. For example, restart Tails between checking your work email and your whistleblowing email.
We are not aware of any such attacks to deanonymize people online who used Tails for different purposes at a time.
If you worry that the files in your Persistent Storage could be used to link your activities together, consider using a different Tails USB stick for each activity. For example, use one Tails USB stick for your activism work and another one for your journalism work.
