mrspoonsi sends news that "Data taken from tens of millions of child abuse photos and videos will shortly be used as part of
a new police system to aid investigations into suspected pedophiles across the UK." The Child Abuse Image Database (CAID) will be available to authorities starting December 11th. It's been populated with data seized in earlier investigations. The database assigns a hash to each photograph, so when a new drive full of illegal images is confiscated, it can immediately be plugged in and quickly scanned to see if there are any matches. It will also catalog GPS coordinates from Exif data.
The purpose of CAID is to eliminate the duplication of effort when investigating these photos. Often when storage drives are seized, they contain thousands or millions of images, and dozens of different police departments could end up unknowingly investigating the same victims. Law enforcement liaison officer Johann Hofmann said, "We're looking at 70, 80, up to 90% work load reduction. We're seeing investigations being reduced from months to days."
