Rekognition is a facial recognition program Amazon sells to law enforcement agencies in Florida and reportedly marketed to US Immigration and Customs Enforcement. The program has been criticized for not being completely reliable, often making mistakes with its matches. Last July, the ACLU found that Rekognition mismatched 28 members of Congress with known criminals using a database of 25,000 mugshots.

Facial recognition in general -- not just from Amazon -- has also been controversial because some see it as an invasion of privacy that's also open to technical problems. In China, a surveillance program mistakenly recognized a face on a bus ad as a jaywalker. Despite the outcry, facial recognition is expanding to airports, concerts and grocery stores.
