Fed up with Password

Hitoshi Kokumai · Few would disagree that the current form of password system is disliked, hated, loathed and fed up with. · Hence our proposition - We do not have to stick to remembering something afresh. We could instead make use of what we remembered many years ago and retained deep in our bra ...


The Tremendous Power of PIN

Hitoshi Kokumai ·            Can a PIN do what the password cannot do? · ‘PIN’ belongs to the secret credential as a numbers-only weak password. Where the PIN is warmly welcomed for providing some security to a passwordless login, we would be watching a ‘password-dependent password-less’ solutio ...


Who Benefits?

Hitoshi Kokumai · "Microsoft promises to ease the pains of going passwordless "   https://www.cnet.com/news/microsoft-promises-to-ease-the-pains-of-going-passwordless/ · The report says “Roughly 200 million people using Microsoft services already have made the jump past passwords”. I would like to ...


Inconvenience behind Convenience of Biometrics

Hitoshi Kokumai · It looks as though nothing is more convenient than putting your finger on a sensor or place your phone in front of your face to get you logged-in. Is it actually as convenient? · Consider the huge inconvenience that citizens would have to face over their lifespan when their biom ...


On Ruinous Misperception of Biometrics

Hitoshi Kokumai · Here are some of my recent writings about the misperception on security-ruining biometrics. · ‘Not as secure as claimed’ is one thing. ‘Harmful to security’ is another. · If Only It Were True · Probabilistic Is Human Body, Not Pattern-Matching Algorithm · US Army appears tobe sca ...


Biometrics - What can a ‘probabilistic authenticator’ achieve in cyberspace?

Hitoshi Kokumai · A big question is too often missing in the discussions about the deterministic authenticators (passwords and tokens) and probabilistic authenticators (biometrics); Are the users to blame when the login fails?’ · When the user fails to feed a correct password and present a correc ...


Two Ways of Deploying Two-Factor Authentication

Hitoshi Kokumai · Using two factors together does not always bring higher security. · Higher security is obtained when two factors are used in ‘multi-layer’ deployment at the sacrifice of convenience, while better convenience is obtained when two factors are used in ‘multi-entrance’ deployment at ...


Technology Obsession and Liberal Arts

Hitoshi Kokumai ·   · ‘PIN’ is an abbreviation of ‘Personal Identification Number’, which is unexceptionally used as an authenticator, not an identifier. · ‘Password’ is defined by the central police agency as ‘Personal Identification Code’ in a country where I was grown up. · Quite a few people ...


Context-dependent Descriptions of ‘Password-less’ Authentication

Hitoshi Kokumai · The word 'Password-less' seems to be multi-semantic depending on the context. Let us break it down. · 1. Where the entire family of passwords is removed from digital identity altogether, we would have only two authenticators - physical token and biometrics. · Since biometrics r ...


What would it be like if 'Entrenched Interests' or 'Sunk Costs' are placed above 'Logic'?

Hitoshi Kokumai ·   · We would be watching a ‘better’ security being achieved by removal of passwords and the passwords being killed by biometrics that is dependent on passwords or being displaced by PIN that is no more than a weak form of numbers-only password as described here  · https://www.beb ...


No Space Left for Expanded Password System?

Hitoshi Kokumai · As discussed earlier, we have to watch a ‘better’ security being achieved by removal of passwords and the passwords being killed by biometrics that is dependent on passwords or being displaced by PIN that is no more than a weak form of numbers-only password. This phenomenon is re ...


What Our Episodic Memory Brings for Identity Assurance

Hitoshi Kokumai ·   · Abstract ·  Three big myths are rampant in the sphere of digital identity. These are ‘Higher security achieved by removal of password’, ‘Passwords killed by the biometrics that is dependent on passwords' and ‘Passwords displaced by PIN that is no more than a weak form of numb ...


Entertaining Security Topics

Hitoshi Kokumai · Current foot brakes are far from sufficient in the slip distance. This means that the foot brake system is dangerous. We have now removed the dangerous foot brake system from the cars we sell. We instead offer the safer cars that are equipped with better steering handles, better ...


Removal of Passwords and Its Security Effect

Hitoshi Kokumai ·   · Assume that the password has been removed from digital identity. Then digital identity platforms would have only two authenticators - physical tokens and biometrics. · Biometrics by its nature requires a fallback measure against false rejection, and on ...


Where to Collect Fingerprints? - On the Phones!

Hitoshi Kokumai · Here is a funny report with a video on ultrasonic fingerprint sensing.   https://www.theverge.com/2019/4/7/18299366/samsung-galaxy-s10-fingerprint-sensor-fooled-3d-printed-fingerprint · Even more intriguing is the report about unlocking by a chewing gum pack.   https://9to5google ...


Big Myths in Digital Identity

Hitoshi Kokumai ·   · (A) What can we make of ‘Password-Dependent Password-Killer’? · (B) What happens where a factor to be enhanced gets removed? · (C) What does ‘PIN-dependent Password-less Authentication’ mean? · - -------------->  ’Illusion of Safety’ and 'Cogni ...


Departure from Text Passwords

Hitoshi Kokumai · Although it is obvious that we can no longer continue to rely on the conventional text-based passwords, we do not support the idea of 'password-less' (will/volition-less) identity authentication, which is not compatible with the values of democracy. · Nor do we support the idea ...


No Need to Wait - Already Defeated by Itself

Hitoshi Kokumai · “AI May Soon Defeat Biometric Security, Even Facial Recognition Software” In this article Artificial Intelligence is taken up as a major threat to biometrics security. · Biometrics is already defeated, however, by itself where it has to depend on a password/PIN as a fallback mea ...
