Microcosm Ltd

Microcosm Ltd is a UK company established in 1979. Its early claims to fame included Silicon Disk System in 1981 and Microcache (the world's first disk cache for microcomputers) in 1982.

Since 1989, it has concentrated on computer security, firstly with CopyControl (a software-based copy protection system), then Dinkey Dongle (small hardware copy protection keys that connect to parallel or USB ports). In 2005, it produced CopyMinder (software-based copy protection that uses the Internet where possible to provide an 'intelligent' copy protection system). More recently, it has expanded its security products by producing SmartSign, a multi-factor authentication system that supports using mobile devices to control access to web pages.
