Tongue Prints Are Unique Like Fingerprints

Just like fingerprints, tongue prints are unique to each individual. The surface of your tongue has distinctive patterns of bumps, ridges, and texture that are as unique as your fingerprints. The tongue's surface is covered with papillae (tiny bumps) that contain taste buds, and these create a unique topographical map for each person. Some researchers have proposed using tongue prints for biometric identification, though this method faces practical challenges compared to fingerprints. The uniqueness comes from the complex combination of papillae distribution, tongue shape, and surface texture that develops differently in each person.
