Scientists in Spain say that they have been successful in creating an "electronic bloodhound" that can sniff out the identifying qualities of each human being. They say that their system is very accurate and simple. Furthermore, the scientists claim that their odor tracking system could easily replace fingerprinting and iris scanning.
Since each person's body odor has recognizable patterns that remain steady, the the rate of accuracy is higher than 85 percent. Due to the fact that it proves less intrusive than other security searches, this new security system could eventually be used in airport security lines or at border control checkpoints. All the technology does is "sniff" the travelers as they walk by.
In most airports or border checkpoints, our identity verification depends on our resemblance to our ID card or passport photo. However, with the new sensors that capture body odor, security searches can be less aggressive. In addition, the process of verifying someone's identity can be less time consuming and more efficient.
