Real / Digital World Analogy
Real world credentials are a diverse social phenomenon, and as such are difficult to define. As with digital signatures it is misleading to assume a direct correspondence between the real-world and the digital concept. This holds even if defining criteria for credentials in the digital world could be agreed on.
The success of digital signatures as a replacement for paper based signatures has lagged behind expectations. On the other hand many unexpected uses of digital signatures were discovered by recent cryptographic research. A related insight that can be learned from digital signatures is that the cryptographic mechanism need not be confused with overall process that turns a digital signature into something that has more or less the same properties as a paper based signature. Electronic signatures such as paper signatures sent by fax may have legal meaning, while secure cryptographic signatures may serve completely different purposes. We need to distinguish the algorithm from the process.

Famous quotes containing the words real, world and/or analogy:
“This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy. And also the only real tragedy in life is being used by personally minded men for purposes which you recognize to be base.”
—George Bernard Shaw (1856–1950)
“Strange to say, the luminous world is the invisible world; the luminous world is that which we do not see. Our eyes of flesh see only night.”
—Victor Hugo (1802–1885)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
