    Re-Chain of fools/whose ceritificate is it anyway, you remember who pushed everyone a few years to switch to ECC, and then stopped doing that? Right, NSA.

    Very similar to the Israeli system (and concerns, though we have some ballot stuffing issues). Many similar concerns (including diaspora) to prevent absentee voting. No polls three days before elections, etc.

    This thread is hilarious. But presentation attacks are a real thing in biometrics. Well known for many years. more info at our winter school on biometrics...

    What about other forms of torture? What was the effect of waterboarding on code quality? Do Spanish Inquisition techniques are as successful as modern torture (despite the low-tech source?) I call for a new Milgram's experiment on developers!

    Many of you will probably have a list of resolutions for the upcoming 2020 (or arrived 2020 if you are in _that_ part of the world). If your list is to become an expert on biometrics, you can start the year by ticking one item from the list by attending our winter school.

    Happy to announce that my long term service at the ICHSA 2020 organization committee has ended. I thank the glorious leader for steering the boat in such high seas, and for his friendship and guidance.

    So much for “biometric security”. Remember, biometrics are passwords you can’t change. So this is 1 million more people who, for the rest of their lives, will be more vulnerable to tracking or impersonation by any hacker or government who happened to grab a copy of this database.

    If you are doing anything related to security/privacy and you use NSA's ciphers Simon/Speck (even "just" for a proof of concept), you are undermining your own credibility that you know what you are doing. Conclusions from workshop.
