English to German Law/Patents Law: Contract(s) Vertraulichkeitsvereinbarung

These terms may not be disclosed to any person other than its employees, attorneys and advisors, and than only in connection with the proposed transaction and on a **confidential need-to-know basis**.

Bei Wiki gibt es folgende Erklärung:
The term "need to know", when used by government and other organizations (particularly those related to the military or espionage), describes the restriction of data which is considered very sensitive.

Under need-to-know restrictions, even if one has all the necessary official approvals (such as a security clearance) to access certain information, one would not be given access to such information unless one has a specific need to know; that is, access to the information must be necessary for the conduct of one's official duties.

Schäfer und Zahn führen den Terminus nicht.
