Our corporate website is ready for Mnemonic Identity Solutions Limited that we registered last August in UK as the headquarters for global promotion of Expanded Password System (EPS)

The website https://www.mnemonicidentitysolutions.com/ provides the trial course with which anyone can freely try and experience the flow of Image-to-Code Conversion by EPS; Pick up 3 to 6 images and you will see a high-entropy code generated from the sum of identifier data of the images you picked up. Select the same set of images and you will see the same code re-generated. This high-entropy code could be used as a very strong password or a mighty seed of cryptographic key.

Assume that you had embedded and selected your ‘hard-to-forget’ and ‘panic-proof’ images of your episodic memory that had been solidly inscribed in your brain for years or decades and you will easily realize why EPS is deployed for national defense in Japan; it has been used since 2013, with the number of users increasing more than 10-fold over the 8 years.

Please do try and experience the trial course; you might well be inspired to think of a lot of practical use cases for solid security and/or friendly useability.
