About the inventor

Matthew Walker, Australian, invented the original PassWindow concept after many years spent researching various online authentication systems. The high cost of many electronic systems as well as their inability to protect against an ever increasing array of complex attacks forced a complete rethink of the way modern authentication is conducted. While the security world looked for ever more complex and high tech solutions which are increasingly vulnerable to ever more complex and high tech attacks, Matthew looked for a radical new solution with pure simplicity at its core and in the process has created an entirely new method in online security..

Security conference organizers, cryptographers, mathematical analysts, press, IT security companies, and those in need of a secure, low cost authentication solution are welcome to contact .
