Confidentiality is the property of a message that it is only intended for a limited group of recipients. Distribution and publication are not permitted. Confidentiality is protected by legal norms , it can also be promoted or enforced by technical means.

Legal norms to protect confidentiality

In Germany, confidentiality is protected by several legal norms.

In the private sector, if the legal regulations on the betrayal of secrets are not considered sufficient, it is common to conclude so-called confidentiality agreements. These agreements regulate the payment of damages in the event of a breach of confidentiality.

Technical aspects to protect confidentiality

Confidentiality is also one of the three most important objectives in information security . It is defined as "the protection against unauthorized disclosure of information". Encryption supports this goal. More complex approaches are known as digital rights management .

Even if measures are used that guarantee confidentiality or are intended to contribute to it (such as encryption), it is possible that a so-called hidden channel is created. A hidden channel is a non-policy-compliant communication channel that can transmit confidential data to an unauthorized recipient. Side channels are a sub-area of ​​the hidden channels.

Law enforcement: witnesses

The German public prosecutor's offices can guarantee confidentiality to witnesses, for example to protect them from reprisals, see key witnesses .
