Canadian election databases use "canary traps"—and they work

Canadian election databases employ "canary traps"—unique, falsified records designed to trace leaks—and they've proven remarkably effective at catching data thieves. Over the past year, these traps identified three insider breaches with 95% accuracy, a rate 40% higher than the typical digital watermarking method. Unlike Reddit's blunt anti-scraping measures at #5, which blocked a legitimate user, canary traps use subtle inconsistencies in records, such as a deliberately misspelled street name, to pinpoint the source without disrupting normal access.
