Two scientist are getting ready to sell there thermal scan cameras to cop stations across the world!
Acohol causes blood-vessel dilation at the skin’s surface, so by using this principle as a starting point the two began to compare data gathered from thermal-imaging scans. One algorithm compares a database of these facial scans of drunk and sober individuals against pixel values from different sites on a subject’s face.
So basically after they scan they can tell by how hot your face is if you you're drunk!
The system could, the paper argues, be used to avoid embarrassing and unfounded reproaches by police officers and officials, who generally make assumptions based on behaviour and appearances alone.
However, it might also annoy a fair few sociable late-night drinkers harmlessly going about their business while having their bodies unwittingly scanned in an intrusive breach of personal privacy.
