Similar to fingerprints, everyone also has a unique tongue print


The tongue is an inimitable organ of the body that is hidden in the mouth. Like fingerprints, a tongue also has a unique print which differs from one another. And whenever the inspection officials want, they can ask the criminals to provide with the tongue print as it cannot be forged. It may be a difficult task to carry on the process of taking tongue print, but it is also the most reliable source to recognize the culprit. This process is not recommended for casual frauds, but only in uncertain and harsh situations.

The tongue shows both symmetrical shape information and biological texture data which are theoretically useful in identity authentication diligences. Along with the difference in print, shape and texture, it is also one of the strong muscles in the human body. For getting the exact tongue print, a study on 3D imaging machine is being established and verified. This is the first endeavor of creating a 3D tongue image record available for the research community, with the decisive goal of advancing the study on tongue biometrics. The new database can be a treasured source for system evaluation, link, and estimate.

There are various ways approved to the tongue print measurement. The first method of distinguishing a tongue is by its shape. You will be surprised to know the different forms of the tongue. It can be long, short, thick, thin, or broad. The second difference could be made from the texture one’s tongue possesses. It’s texture also has many variants like rims, marks, wrinkles, and layers. All these physical features can be taped using a ‘tongue image-acquiring device’, which is mainly a high-tech digital camera and afterward administered using tongue investigative software.

In one of the investigation, it was found that the microorganism in the human mouth is as authoritative as a fingerprint at recognizing an individual’s origin. Researchers discovered around 400 diverse classes of a microscopic organism in the mouth of 100 contributors who belonged to four groups, namely -non-Hispanic blacks, whites, Chinese, and Latinos. The investigation presented that only 2% of microbial types were shown in all individuals, in various intensities to their origin. And 8% microbial kinds were discovered in 90% of the participants. Furthermore, scientists also found that each racial group was symbolized by a mark of common microscopic unities.
