Lip prints and fingerprints are said to be unique to each person. The analysis of fingerprints and lip prints is widely used in the identification of the deceased as well as in criminal investigations. However, due to similarities in the structure of the skin and fat under the surface, it is possible for someone to fake a fingerprint or copy one from another source.
Fingerprints are located on the pads of fingers and contain special patterns that are unique to each person. Because these patterns are based on the position of blood vessels, sweat glands, and nerve endings, no two people have the same set of fingerprints.
Similarly, the pattern of fat beneath the skin on the face is unique to each person. This area contains many large veins and arteries as well as several groups of tiny sebaceous (oil) glands. Like fingerprints, these facial features are responsible for determining personal identity. Although there are some differences between men and women's faces, the overall pattern of fat is similar for everyone.
The term "lip print" is used to describe the pattern of color and texture found at the site of an injury to the lip. These patterns can be used to identify the person who caused the injury. Just as with fingerprints, no two people have the same set of lips, so lip prints are unique to each person.
Lip prints are one-of-a-kind and can be used to identify individuals. There are very few studies that prove its admissibility as biological evidence in a court of law. However, it is not uncommon for police departments to use lip prints to make an identification.
The validity of the technique depends on many factors such as the quality of the print, the experience of the tester, and the type of paper used to develop the print. Also, certain substances like food coloring or alcohol can affect the outcome of the test.
Individuals will typically wear their lip prints for several days before they are reported by witnesses or victims.
In conclusion, yes you can be identified by your lip print.
During the weeklong trial, however, two state police crime laboratory experts testified that lip prints, like fingerprints, are unique to the individual and can be recognized using the same procedures.... Neither expert was able to say whether this particular set of prints came from defendant's lips.
In conclusion, the Lip Print Evidence is not reliable for use as evidence in criminal proceedings.
Various ways of collecting, analyzing, and interpreting lip prints have been proposed in the literature, including usage in postmortem identification, the use of magnifying glasses, the use of rulers in software, the use of fluorescent dyes, and the use of fingerprint powder.
Latent lip print evidence can be collected in a variety of ways, such as at the scene of the crime during initial contact with the victim or after the fact by taking photographs or video recordings of the lips. In some cases, an expert may be needed to interpret this evidence.
In conclusion, lip prints are unique to each person and can be used in place of fingerprints for identifying suspects of crimes.
