Examples of this practice include disguising sensitive information within commonplace items, like a piece of paper in a book, or altering digital footprints, such as spoofing a web browser's version number. While not a standalone solution, security through obscurity can complement other security measures in certain scenarios. [1]
Steganography (/ˌstɛɡəˈnɒɡrəfi/ ⓘ STEG-ə-NOG-rə-fee) is the practice of representing information within another message or physical object, in such a manner that the presence of the information is not evident to human inspection. Generally, the hidden messages appear to be (or to be part of) something else: images, articles ...
This concept is widely embraced by cryptographers, in contrast to security through obscurity, which is not. Kerckhoffs's principle was phrased by American mathematician Claude Shannon as "the enemy knows the system", [ 1 ] i.e., "one ought to design systems under the assumption that the enemy will immediately gain full familiarity with them".
In computer security, the debate is ongoing as to the relative merits of the full disclosure of security vulnerabilities, versus a security-by-obscurity approach. There is a different (perhaps almost opposite) sense of transparency in human-computer interaction , whereby a system after change adheres to its previous external interface as much ...
Simply making source code available does not guarantee review. An example of this occurring is when Marcus Ranum, an expert on security system design and implementation, released his first public firewall toolkit. At one time, there were over 2,000 sites using his toolkit, but only 10 people gave him any feedback or patches.
Some encryption systems will claim to rely on a secret algorithm, technique, or device; this is categorized as security through obscurity. [2] Criticisms of this are twofold. First, a 19th century rule known as Kerckhoffs's principle , later formulated as Shannon's maxim, teaches that "the enemy knows the system" and the secrecy of a ...

There are many examples of vulnerabilities being discovered simultaneously, often being exploited in secrecy before discovery by other researchers. [21] While there may exist users who cannot benefit from vulnerability information, full disclosure advocates believe this demonstrates a contempt for the intelligence of end users.
