Lots of you mentioned that when you go to high school next year you will be paying for your lunches through fingerprint recognition. We chatted about this and had lots of questions about it.
- How do you think fingerprint recognition works? Think about the hardware needed and then the software and coding – decompose it…
- What advantages does paying with your fingerprint have, instead of using cash? Think about benefits for you, the school and the school caterers – why choose a fingerprint?
- Your fingerprint provides “biometric” data about you. Find out what this means and what other types of biometric data could be used instead.
- Who has copies of your fingerprints and why might this matter to you?
- “Schools and colleges must now ensure that written consent is obtained from parents before a child’s biometric data is taken and used and must make alternative arrangements if the request is refused.” As a child, are you happy with your parents taking this decision on your behalf? Why?
Sorry about the Apple advert but here’s an interesting video explaining how the iphone uses fingerprint recognition:
There’s some more information here.
Updates after session:
We discovered there are 3 types of fingerprint – Ulnar Loop (4 of us – 33%), Plain Arch (only 2 of us – 17% ) & Plain Whorl (6 of us – 50%!). In the main population, 60% have Loops, 5% have Arches and 35% have Whorls. We pressed our fingerprints on uninflated balloons, then blew them up to get a closer look!
Information we’d like before giving our biometric data away included:
- Why do you need it?
- What will it be used for?
- Who will have access to it?
- Will it be kept safe?
- How long will it be kept for?
