From 1910 to 1920, radio was increasingly used for private, business, and military communication. As this communication was open, it was very easy to eavesdrop.
To prevent eavesdropping, the first Enigma machine was invented and patented by Arthur Scherbius in 1918. It was a very complicated cipher machine based on rotating wired wheels. Mass production of the Enigma machine started in 1925.
Today we have a similar situation with Internet communication. To prevent eavesdropping, many websites use encrypted communication. Some organisations use virtual private networks (VPN) when working with email for example.
The idea behind Comfact Delivery is that it should be easy to use for anyone while maintaining a very high level of communication security.
