‘Easy-to-Remember’ is one thing. ‘Hard-to-Forget’ is another - The observation that Images are easy to remember has been known for many decades; it is not our theme. What we discuss is that ‘images of our emotion-coloured episodic memory’ is ‘Hard to Forget’ to the extent that it is ‘Panic-Proof’; images of toys, dolls, dogs and cats, for example, that our children used to love for years would jump into our eye even when we are placed in heavy pressure and caught in severe panic. Expanded Password System (EPS), which accepts images, especially the unforgettable images of our own emotion-coloured episodic memory, as well as conventional characters and numbers, is intended to be a legitimate successor to the time-honoured seals, autographs and text-only password systems for safe digital identity over many generations to come, In the present-day world, safely protected teleworking, telemedicine and many other tele-something in the stressful pandemic situations as well as many natural and manmade disasters is among the imminent objectives.

1. Digital Identity for Global Citizens
Identity Assurance by Our Own Volition and Memory
proposed by
Mnemonic Identity Solutions Limited
United Kingdom/Japan
21 November, 2020

2. Problem - Password Predicament
Secret credentials are indispensable for identity assurance,
whereas text-only passwords are hard to manage.
Why not consider Non-Text secret credentials?

3. Solution - Expanded Password System
There are several known
images in the matrix
Only I can select all of
them correctly

4. Theory - Science of Human Memory
With emotion-colored episodic image memory,
‘Hard-to-forget’ secret credentials are easily achievable

5. Use Cases
Consumers – 140,000 online shoppers enjoyed friction-
less login from 2004 to 2008
Corporations - 1,200 people enjoying secure login by 2-
channel authentication since 2014
Military – ‘Panic-proof’ field use at Japan’s Ground Self-
Defense Force (Army)

6. Mission
Make Expanded Password System solutions readily available to
all the global citizens –
rich and poor, young and old, healthy and disabled, literate and
illiterate, in peace and in disaster –
over many generations until humans discover something other
than 'digital identity' for our safe and orderly societal life.

7. Another Mission
For global citizens to enjoy a safer identity assurance,
we need to debunk wide-spread misperceptions such as
“indispensable passwords be removed altogether”
and
“passwords be displaced by password-dependent biometrics”

8. Who We Are
Mnemonic Identity Solution Limited was
founded in UK in August 2020 by Hitoshi
Kokumai (left), who invented Expanded
Password System in 2000 in Japan.
Now launching the global operations from UK.
