Furtive - Technology Secrecy

Technology Secrecy

Preservation of secrets is one of the goals of information security. Techniques used include physical security and cryptography. The latter depends on the secrecy of cryptographic keys. Secrecy is central to organized crime. Many believe that security technology can be more effective if it itself is not kept secret.

Information hiding is a design principle in much software engineering. It is considered easier to verify software reliability if one can be sure that different parts of the program can only access (and therefore depend on) a known limited amount of information.
