Forgergy
Forgery describes the process of making or adapting objects or documents, with the intention to deceive. Copies, studio replicas, and reproductions are not considered forgeries, though they may later become forgeries through knowing and willful mis-attributions. In the 16th century imitators of Albrecht Dürer's style of printmaking improved the market for their own prints by signing them "AD", making them forgeries.
In the 20th century the art market made forgeries highly profitable. There are widespread forgeries of especially valued artists, such as drawings meant to be by Picasso, Klee, and Matisse.
This usage of 'forgery' does not derive from metalwork done at a 'forge', but it has a parallel history. A sense of "to counterfeit" is already in the Anglo-French verb forger "falsify."
Forgery is one of the techniques of fraud, including identity theft. Forgery is one of the threats that have to be addressed by security engineering. -- http://wikipedia.com/wiki/Forgery
