In principle, any service could be used by the government for control and surveillance. For this reason, transparency, clarity, and trust of the service's function are vital to the user.

Since there is no central instance involved in the Mix concept, all Mixes involved in a Cascade would need to work together in order to track a connection. Because of this, any kind of observation of the internet user, including from the side of the government, is not made easier, rather more difficult by using JonDo.

In contrast to all othr anonymization systems (also Tor and I2P, for example), not even the last Mix (the exit server to the "normal" internet") is able to follow a user's steps in the long run. Each internet request is individually anonymized and cannot be linked to a specific user - as far as your browser configuration is correct.

Of course, such anonymization services especially attract interest for surveillance. We are definitely aware that unobservable internet usage is for this reason especially important for users of the anonymization service. The JonDonym technology is therefore always being developed under the aspect of high security and distributed control.
