According to the Federal Criminal Police Office (BKA), 99,375 of the 205,728 reports forwarded by the US-based National Center for Missing and Exploited Children (NCMEC) were not criminally relevant, an error rate of 48.3%. This is a rise from 2023, when the number of false positives already stood at 90,950.
Indeed 50% false positive rate sounds surprisingly good, but this is under the "voluntary scheme" where Meta/Google/MS etc are not obligated to report. Notably missing from the article is the total number of scanned messages to get down to 200k reports. To my knowledge, since it's voluntary, they can also report only the very highest confidence detections. If the Danish regime were to impose reporting quotas the total number of reports would rise. And of course -- these are reports, not actually convictions.Presumably the actual number of criminals caught by this would remain constant, so the FP rate would increase. Unless of course, the definition of criminal expands to keep the FP rate low...
