Biometrics: one measure to rule them all

Tuesday 30th April 2019630pm till lateJuJu's Bar and Stage, 15 Hanbury St, London, E1 6QRFREE

This month's edition of CryptoParty London will include a special mix of talks and workshops, with talks on biometrics and its use across an increasing number of sectors, as well as electronic music and crypto-themed cocktails.

A technology based on capturing and measuring particular traits of our bodies, for its very nature biometrics can raise serious concerns in terms of privacy and human rights.

We will also have an update talk on the case of Julian Assange, and its ramifications in terms of human rights and freedom of the press.

Come for the talks and stay for an amazing series of privacy self-defence workshops. Learn how to use privacy enhancing applications to, for instance, improve the security of your online communications and safely browse the internet.

Join us from around 6pm with talks kicking off at 630pm sharp. We'll be hosted by awesome Juju's, in East London. Free entrance, all welcome, no registration needed.

Talks + Q&A

630pmCarly KindBiometric technologies, NGOs, and humanitarian interventions - talk + Q&AWith the numbers of refugees and asylum seekers continually growing, and international foreign aid shrinking, humanitarian and refugee assistance organisations are under more pressure than ever to improve the accuracy and effectiveness of their interventions. Biometric technologies are being touted as a solution to this problem, accompanied by claims that they can decrease fraud and establish the veracity of asylum claims. But a critical analysis of biometrics show that such claims are overblown, and are often outweighed by the significant negative implications of biometrics for individual privacy and autonomy. Carly will explore some of these issues with reference to a 2018 review she produced with The Engine Room for Oxfam on the use of biometrics in the humanitarian sector.
700pmGriff FerrisThe State of Biometrics Do you know how the government is using your biometrics to track and identify you? Find out how several police forces across the UK have been targeting and tracking people using their facial biometrics, and a what happened when a government department took hundreds of thousands of people's voice biometrics over the phone without their knowledge - and how hundreds of thousands reasserted their right to privacy.
715pmNiels LadefogedUpdates on the case of Julian AssangeAn update talk about Julian Assange, following his eviction from the Ecuadorean embassy and his arrest by the UK police. The talk will reconstruct the recent developments of the case and will explore some of the worrying implications that this may have in terms of freedom of the press and human rights.

JustineBiometrics under the hoodHow biometrics work from a technical point of view. A brief summary and high-level view of the maths, and an actual demo (live-coding included!) using a facial recognition model. How your face (or other biometric) is reduced to a mathematical representation and how it's then used to compare to others so as to detect you. Power and limitations.


Why CryptoParty?

Privacy is the space in which ideas are developed, to retreat into whenever you want. This space is not only physical but digital as well. Governments and companies don't want to respect that so we become active ourselves.

What is a CryptoParty?

CryptoParties are free and open for everyone, but especially those without prior knowledge, who haven't yet attended one.

CryptoParty is a decentralized movement with events happening all over the world. The goal is to pass on knowledge about protecting yourself in the digital space. This can include encrypted communication, preventing being tracked while browsing the web and general security advice for computers and smartphones.

To try the programs and apps at the CryptoParty bring your laptop or smartphone.
