What is a "backdoor": A "backdoor" offers unrestricted access to the law enforcement agencies and intelleigence services without support of the service operators. Such a "backdoor" was built into the Greek Vodafone network for law enforcement wiretapping capabilities and was requested by FBI director Robert Mueller from US companies. If Mueller’s wish were granted, the FBI would gain undetected real-time access to suspects’ Skype calls, Facebook chats, and other online communications and in "clear text". Such a "backdoor" is not part of JonDonym. JonDonym law enforcement: It is possible, to deanonymize a single user by some features (user IP address, website monitoring or user account). The idedentify feature for the malicious user has to be provided by the law enforcement agency and all operators have to get an official order in their country. The deanonymisation can only be done by collecting all log together (usually done by the law enforcement agency), it can not be done by a single mix operator. All other user of JonDonym will use the mix cascades without logging.
