The Biba Model or Biba Integrity Model developed by Kenneth J. Biba in 1975, [1] is a formal state transition system of computer security policy describing a set of access control rules designed to ensure data integrity.
The model was described in a 1987 paper (A Comparison of Commercial and Military Computer Security Policies) by David D. Clark and David R. Wilson.The paper develops the model as a way to formalize the notion of information integrity, especially as compared to the requirements for multilevel security (MLS) systems described in the Orange Book.
The security policy must be explicit, well-defined, and enforced by the computer system. Three basic security policies are specified: [6] Mandatory Security Policy – Enforces access control rules based directly on an individual's clearance, authorization for the information and the confidentiality level of the information being sought.

Confidential computing is a security and privacy-enhancing computational technique focused on protecting data in use.Confidential computing can be used in conjunction with storage and network encryption, which protect data at rest and data in transit respectively.
Confidentiality refers to the "quality or state of being private or secret; known only to a limited few", [2] or "the property that information is not made available or disclosed to unauthorized individuals, entities, or processes".
