Confidentiality is an ethical principle associated with several professions (e.g., medicine, law). In ethics, and (in some places) in law and alternative forms of legal resolution such as mediation, some types of communication between a person and one of these professionals are "privileged" and may not be discussed or divulged to third parties.

Confidentiality has also been defined by the International Organization for Standardization (ISO) in ISO-17799 ^[1] as "ensuring that information is accessible only to those authorized to have access" and is one of the cornerstones of information security. Confidentiality is one of the design goals for many cryptosystems, made possible in practice by the techniques of modern cryptography.

Confidentiality of information, enforced in an adaptation of the military's classic "need to know" principle, forms the cornerstone of information security in today's corporations. The so called 'confidentiality bubble' restricts information flows, with both positive and negative consequences.

Using the word confidential painted onto the cardboard envelopes because in the session of Aaron Johnson' s assassination, there has been documented work documented into the folders along side with journals and personal information regarding to the factors of his past. We wanted (want) to pull the attention of the audience (player) to notice the bold letters on the envelop to pull the intentions of the players to open this confidential information.  After talking to Maggie once again, our plans of the assignment began to alter. We were puzzled at the fact that we were wanting to include very complex clues scattered around the regions of our design building and library. We were confused about how to incorporate these clues to reflect the idea of using conspiracy theories in this assignment. We wanted to covey the idea of producing some very interesting clues and observations that his will make the experience more fun and game interesting.
