Secrecy

For the DC Comics character, see Secret (comics).

Secrecy is the practice of hiding informationfrom others. That which is kept hidden is known as the secret. Secrecy is often controversial. Many people claim that, at least in some situations, it is better for everyone if everyone knows all the facts?there should be no secrets. Closely allied?perhaps synonymous?notions of confidentialityand privacyare often considered virtues (One should keep confidences and respect privacy.)

Natural and sociological secrecy

Secrecy is built into biology. One reason for sexual reproductionand speciationmay be to allow members of a species to share genetic improvements without their becoming available to competitors. Animals, including humans (in some cases), generally endeavor to conceal the location of their denor nestfrom predators. (In practice, finding a human is often not difficult, especially with the aid of telephone directories, private eyes, etc. ) Humansattempt to consciously conceal aspects of themselves from others, due to, for example, shameor fearof rejection, loss of acceptance, loss of employment, or other negative repercussions. On a deeper level, humans attempt to conceal aspects of their own selfwhich they are not capable of incorporating psychologically into their consciousbeing. Familiessometimes maintain "family secrets", using a mutually agreed-upon construct (an official family story) to never discuss disagreeable issues concerning the family, either within the family or with those outside the family. Agreement to maintain the secret is often coerced through the use of such tactics as "shaming" and reference to family honour. On occasion, the information may be something innocent such as a recipe.

Government secrecy

Governmentsoften attempt to conceal information from other governments or the public. These state secrets can include weapondesigns, military plans, diplomaticnegotiationtactics, and secrets obtained illicitly from others ("intelligence"). Most nations have some form of Official Secrets Act(the Espionage Actin the U.S.) and classify material according to the level of protection needed (hence the term "classified information"). An individual needs a security clearancefor access and other protection methods, such as keeping documents in a safe, are stipulated.

Few people dispute the desirability of keeping Critical Nuclear Weapon Design Informationsecret, but many believe government secrecy to be excessive and too often employed for political purposes. Many countries have laws that attempt to limit government secrecy, such as the U.S. Freedom of Information Actand sunshine laws. Government officials sometimes leak information they are supposed to keep secret. (For a current (2005) example, see Plame affair.)

Corporate security

Organizations, ranging from multi-national for profit corporationsto nonprofit charities, keep secrets for competitive advantage, to meet legal requirements, or, in some cases, to conceal nefarious behavior. New products under development, unique manufacturing techniques, or simply lists of customers are types of information protected by trade secretlaws. The patentsystem encourages inventors to publish information in exchange for a limited time monopolyon its use, though patent applications are initally secret. Keeping one's strategysecret is important in many aspects of game theory. Secret societiesuse secrecy as a way to attract members by creating a sense of importance. Secrecy is central to organized crime.

Other laws require organizations to keep certain information secret, such as medical records(HIPAAin the U.S.), or financial reportsthat are under preparation (to limit insider trading). Europehas particularly strict laws about databaseprivacy. The U.S. even has a special law protecting records of video tape rentals and sales (18 USC 2710), apparently passed when members of Congress realized their video viewing habits could be politically embarrassing.

Technology of secrecy

Preservation of secrets is one of the goals of information security. Techniques used include physical securityand cryptography. The latter depends on the secrecy of cryptographic keys. Many believe that security technology can be more effective if it itself is not kept secret. See Full disclosure, Kerckhoffs' law, Security through obscurity.

Information hidingis 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 only have access to certain information.

Hazards of secrecy

Excessive secrecy is often cited as a source of much human conflict. One may have to liein order to hold a secret, which might lead to psychologicalrepercussions. The alternative, when asked about something, declining to answer, may suggest the answer and may therefore not always be suitable to keep the secret. Also the other may insist that one answers the question. See also Don't ask, don't tell.
