When your password leaks:→ Change your password→ Problem solved

When your password leaks:
→ Change your password
→ Problem solved

When your biometric data leaks:
→ You can't change your face
→ You can't change your fingerprints
→ The compromise is permanent
→ Your biometric data is in breach databases forever

This is why facial recognition for age verification is dangerous.

@capitainesam Also maybe not use your fingerprint to unlock your phone if your not 100% sure it stays on the device (even if the device is stolen etc.)

[deepbluev7@nheko.io]

@capitainesam@mastodon.social That's why in quality land you have to pay via touch kiss, because a payment provider leaked the other biometrics already.

[dancingtreefrog@mastodon.social]

@capitainesam Don't use biometrics to unlock phones. Police and criminals can grab your hand or aim the phone at your face to unlock your phone regardless of your wishes. They have to ask you for password/PIN; they don't have to ask to simply stick your finger on the phone screen or point the phone at your face.

[dancingtreefrog@mastodon.social]

@capitainesam So maybe you combine biometrics with password/passkey?

One of the foundational stories of cyberpunk illustrated a defense against biometrics fraud. The hackers targeted a victim that used fingerprint login. They managed to get a copy of the victim's fingerprint and used it.

Then the victim's security system kicked in - because the victim always deliberately *failed* the first finger login and used their *second* finger login...

@capitainesam
There's some trans ladies on here that have done a pretty good job at some of this...

@capitainesam Thanks for the reminder; I'm overdue to rotate my retinas for this quarter.

[pouakai@mastodon.social]

@capitainesam
And UK, some states in US, even several countries in EU are not aware of this.

The politics are either don't care about their people, or too ignorant to realise the risk.

[ill_logic@mastodon.social]

@jfml @capitainesam I would hope that your phone takes a "fingerprint" of your fingerprint, i.e. enough to verify but not reconstruct.

[mildpeach@mstdn.social]

@capitainesam or any other biometric…

@capitainesam

> You can't change your face

Not with that attitude

[vrek@mastodon.social]

@dancingtreefrog @capitainesam I'm curious and a fan of cyberpunk... What book are you referring to?

[simonzerafa@infosec.exchange]

@capitainesam

Just say No to Biometric Identity Verification 🙂🖖

[dancingtreefrog@mastodon.social]

@vrek @capitainesam I seem to recall that it was William Gibson's Neuromancer; the incident that lead to the main character's nervous system being crippled by the Russian mafia. But it's been awhile since I read it, I could be mistaken.

[vrek@mastodon.social]

@dancingtreefrog @capitainesam hmm... I read that too but same as you it's been over a decade, might be time for a re-read

[htpcnz@mastodon.social]

@capitainesam until you start abusing billionaires biometric data, nothing will ever happen... Even then only use of theirs will be quickly outlawed.

[j_a_clausen@mastodon.social]

@capitainesam also, those biometric data will inevitably be leaked. One glimmer of hope is that bit rot will render them useless over time

@capitainesam@mastodon.social @negative12dollarbill@techhub.social yeah, easy. just get plastic surgery, duhhhhh /j
