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.^[1]

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.
