Fingerprints are considered as a mark of identity as they are person specific. But a few of us know that not only are the finger prints but there are also other parts which are person specific.
Here are some of these,
Iris
Eyes are the window to your soul and your identity. The iris, a muscle that opens and closes the pupil to control how much light enters the eye, has tiny textural patterns. DNA determines the color and structure of the iris, but its random pits, furrows, swirls, and rifts occur during fetal development, which makes every iris unique (even your two irises don’t match each other). The patterns are thought to appear as the fetus opens and closes its developing eyes, and iris tissues tighten and fold.
Ear
Trace the rim of your ear: Feel those curves and ridges? You’re the only person in the world with that exact shape. The ear is such a handy identifier that Yahoo is developing technology to unlock smartphones with an ear scanner. Someone receiving a call would unlock the phone by simply pressing it to the ear.
Lip print
Hypothetically, detectives could seal evidence with a kiss. A study in the Journal of Forensic Dental Sciences found that the pattern of elevations and depressions in the lips are as unique as fingerprints. There’s just one problem: Though lip prints have been used as identification in the court in isolated cases, criminals typically don’t smooch crime scenes.
Tongue
Like a fingerprint, the tongue has its own shape and texture, and its tiny bumps and ridges are distributed in a way that is uniquely yours. These patterns rarely change over time since the tongue is protected inside the mouth (unlike fingertips, which may become scarred). Researchers are developing 3-D tongue imaging to aid in identification.
Voice
It’s not quite a body part, but your voice is unlike any one else’s. Some vocal characteristics are easy to detect, such as frequency (high or low) and intensity (loud or soft). Based on the combined traits, scientists have already created systems to automatically recognize a person’s voice if it is pre-recorded in a database.
Toe print
A fetus’s toe prints develop at the same time as fingerprints, and are just as unique. Since crooks are more likely to leave fingerprints behind, the FBI maintains a national database that links 66 million people to their fingerprints, but does not record foot or toe prints.
