Freedom to Tinker – Seals on NJ voting machines, 2004-2008

Those five criteria are just common sense about what would be a required in any effective system for protecting something using tamper-indicating seals. What I found was that (1) the seals aren’t always there; (2) even if they were, you can remove the cartridge without visible evidence of tampering with the seal and (3) you can remove the circuit-board cover without even disturbing the plastic-strap seal; (4) even if that hadn’t been true, the seal-inspection records are quite lackadaisical and incomplete; and (5) even if that weren’t true, since the counties tend to re-use the same serial numbers, the attacker could just obtain fresh seals with the same number!
