Instead of providing the lunches to all students without question, they made the program opt-in. Since not all students get the lunches, they needed a way to track who was getting them.
Officials decided the best way to do so would be to invest in biometric software that scans students's thumbprints every time they pick up lunch.
The data collected by these scanners goes not just to the school district, but to the federal government as well.
for roll call for senior students, which savvy kids may be able to circumvent with sweets from their lunch box.
The system replaces the school's traditional sign-in system with biometric readers that require senior students to have their fingerprints read to verify attendance.
The school principal says the system is better than swipe cards
because it stops truant kids getting their mates to sign-in for them.
But using the Gummi Bear attack,
students can make replicas of their own fingerprints from gelatin, the ingredient in Gummi Bears, to forge a replica finger.
The attack worked against a bunch of scanners that detect electrical charges within the human body, since gelatin has virtually the same capacitance
as a finger's skin."
