Dogs Are Being Trained To Sniff Out SD Cards and Flash Drives



We’re all familiar with drug-sniffing dogs that are used by airports and other installations around the world, but have you ever heard of dogs that sniff out electronic storage media? K-9 dogs are now being trained to sniff out digital storage, such as cellphones, thumb drives, computers, and memory cards. In addition, the dogs are used in other scenarios like counter-terrorism cases where someone could be storing documents or plans on a hidden thumb drive and in cases of fraud where proof of fraudulent businesses or forged documents could be found on a concealed laptop. So, how exactly do these dogs manage to smell something that doesn't have much of a scent? Humans have about six million olfactory receptors in their noses, while dogs have up to 300 million. With extensive training, they can actually pick up the scent of TPPO, which is a chemical that coats memory chips to protect them from overheating. The K-9s don’t, however, come cheap. Most organizations shell out in the neighborhood of $10,000 per dog for the highly-specialized training. As far as the dogs are concerned, finding evidence that helps police is a series of fun games and all in a day’s work.
