Every time you swipe your phone, you are leaving an important piece of you behind. Researchers of the University of California, San Diego conducted a trace analysis of the chemicals of 39 phones surrendered by volunteers. Based on their findings, scientists tried to create a profile detailing the behavior and the possible identity of the user.
Amina Bouslimani, the lead researcher, noted that on average, a person spends five hours on a mobile device. This is one reason why phones are similar to a person’s skin since the “phone also reflect who you are and what you do.” Each time your fingers touch your screen, you can leave chemical traces that could expose a lot about you.
