The fingerprints of each person are one-of-a-kind. This means that no one else on the planet has the same ridges and lines on their fingertips as the other.
This is the same even for identical twins. Not just the fingerprints but here are some body parts that are as unique as your fingerprints.
The muscle in our eye that controls how much light enters the eye is called Iris. The colour and pattern are determined by DNA, but its irregular holes and wrinkles make each iris unique.
Your lip furrow pattern of elevations and depressions is as unique as fingerprints. Thus, lip prints can also be used as evidence in court.
The spikes, contours and ridges on the outside of the ear are quite distinctive, but they can distinguish one person from another.
Like a fingerprint, the tongue also has its form, texture, with small bumps and ridges scattered in a pattern that is unique to you.
The lines in the fingers or toes form at the same moment throughout fetal development. These patterns differ from one individual to the next.
Dental characteristics like tooth morphology, size differences, missing teeth, overcrowding of teeth and colour give each person a distinct identity. Hence dentures are also unique.
The retina would be a perfect snapshot of your neural system that is unique and makes you.
The distinctive vocal tract of each person is partly hereditary and partly learnt, the size of someone's neck and pharynx plays a role, features like lip curving and word pronunciation.
The Toe prints, just like fingerprints, are used in court as sole evidence as they are also unique.
Maybe not 100% but Gait identification could be used to identify people from a distance. According to research, about 99.6% of people had different walking styles, foot pressure etc.
