Everybody uses PIN code today. With your mobile, your credit card, your token. It’s a good security practice: A two-factors authentication with something you have (a token) and something you know (a PIN code). But the problem remains always the same: humans have difficulties to remember codes!
GrIDsure worked on a new system based on patterns. Studies showed that the human brain can easily remember forms or patterns instead of codes.
How does it work? First, you need to define your own personal pattern and remember it. Later, when you need to authenticate, use their terminal device. It displays a grid filled with random numbers. Just remember your pattern: it’s your temporary unique code!
