Im studying lip prints for my under grad project. I have been trying to retrieve DNA from lip prints for profiling. Has anyone done any similar research or have any relevant info for me? | ||

hi i dont think that still there is enough material available for lip prit analysis. this is my suggestion to all researchers working in this area that be in touch with other scholars also so that you can share your experiences and can discuss to find something new. i have some interesting features on lip prints. feel free to email me at:itsyogeshvats@rediffmail.com (Message edited by yogeshvats on September 23, 2008) | ||

Your problem is that there has been only a little work done to establish a scientific basis for identification of impressions of skin based on pores, creases, scars, etc., rather than the special characteristics of the friction ridge skin found on the palmer surfaces of hands and feet. It's logically true that when you examine any biological surface in sufficient detail that you will find that surface to be unique. But that is far from demonstrating to the courts that the uniqueness has been adequately established by studying the way in which the skin features were formed and a body of work that has led to that sort of examination being regularly done and accepted by a community of experts. One could, for instance, claim that zebras can be positively identified by the pattern of their stripes. What we know in general supports that claim. But we might find it difficult to find studies addressing the specific the biological process of forming the patterns. There is enough known about how fingerprints form to presume them to be unique. Creases on hands and feet may also be factors in identification, and we know those creases form and change in different ways. We don't know that much about lip creases. We would have to know, not only all the ways lip creases form, but we would have to know about how new creases form and how creases can change over time. Because fingerprint identification has such a long history, it first became acceptable evidence based on the argument that examination of many fingerprints had not found any to be identical beyond a certain minimum area of detail. That kind of assumption made from experience is no longer sufficient to make such evidence admissible, but a great deal more is known now, enough to establish the scientific basis for identification. Lip prints were suggested as a criminal investigation tool in 1932, but there have been few opportunities to apply it. If humans were designed in such a way that we had to manipulate objects with our lips, it is likely we would find lip print identification much better studied and developed as evidence. This is the point, that there are many human features that can be used to identify, but few that have been validated. You might get some direction to some of the research and application by putting LIP PRINT IDENTIFICATION into Yahoo or Google. Look for Dr. Anil Aggrawal's article. He discussed Dr. Suzuki's attempt to classify lip prints. You should also search on EAR PRINT IDENTIFICATION. The issues are similar, and there are legal cases relating to both lip prints and ear prints. I had a case in which a man pressed his face against a glass door before breaking into a house. He left quite a good impression of most of one side of his face in fine detail. You could get a reasonably good idea of his facial appearance from the impression. No one would, however, be allowed to testify that they had identified him by the impression. One of the problems is that detailed lip, ear, and face impressions are rarely found in criminal investigation, so there has not been much motivation to work on the problem. I suggest you begin with an examination of the evolution of fingerprint identification and the research that supports it and then compare the work done on lip prints. You will find many legal citations on fingerprints but only a very few on lip prints. The rarity of potentially identifiable lip prints in actual cases has not provided the means of fully exploring the legal issues. You may also find it useful to examine the nature or such things a shoe print and tire print identification to see what kind of knowledge is required to validate a comparative identification of surfaces by their impressions. | ||

hi...I am doing some researches on lip prints recognition.I want to know more about how lip prints to be used in identification .I want to ask how we can analyse the lip prints.is there any software available for it who are the investigators who work with this kind of identification, and all information who you may share with me. Thanks. Please feel free to email me at:sran2005@gmail.com | ||

have there been any recent studies on lip print identification. I am doing a legal analysis in light of the Davis case for a Forensic Evidence Law Class and I'm having trouble finding more information. Thank you... Please feel free to email me at: Littlemissangelique@gmail.com Angelique | ||

I have examined latent and inked elbow prints and conducted analysis, comparison, evaluation and reached a conclusion of individualization. These were test impressions, but yes... this is possible. If testimony in court is the end result, however, there would need to be some work completed on validation, scientific basis, and Daubert related concepts. If you have specific questions or would like to discuss some literary citations for the permanence and uniqueness of non-friction ridge skin, let me know. I have several sources that would be good for this. -Kasey Wertheim, kaseywertheim@aol.com | ||

can elbow prints be used to identify an individual and if so are there any cases where this has happened? | ||

The simple answer is yes, Tsuchihashi in Japan and many others have studied lip print impressions... called "ko shimon" (mouth fingerprints) in Japanese. It would probably be easier to ask, "In the centuries of medical study and thousands of years of simple human observations, have there ever been two persons found to be exactly alike in every way?" Differential growth and environmental conditions cause uniqueness during prenatal development. In general all humans are different if they are examined (sampled) to a degree sufficient to document their differences. The single exception is DNA... which can be the same between identical (monozygotic) twins. It is not so much a matter of whether or not your lips, ears, freckle pattern, fingernail ridges, elbow creases, birthmarks, skin pore patterns on your forehead, etc., are unique... it is more a matter of whether the quality and quantity of information sampled in the image or impression are sufficient to prove the uniqueness. Sampling lip impressions left in sand (for example) will not record meaningful detail insofar as unique crease formations. Some minute differences can be quite difficult to discern/capture/record in detail fine enough to differientate without using microscopes or other special instruments/materials. Don't expect to find experts in identifying lip impressions, ear prints, fingernail (underside) ridges, elbow creases, etc., in very many crime labs. Validation and admissibility issues regarding scientific procedures involved in such identifications and the training, experience, abilities of individual practitioners have a difficult time meeting scientific and professional standards set by disciplines such as friction ridge identification. Friction ridges on hands and feet are prominent features easily observed and recorded... and often left behind as trace impressions. Fingerprints have been studied longer and more thoroughly than any other human identification feature. Latent print identification has been recognized by the courts as the very archetype of reliable expert testimony under modern Daubert admissibility standards. | ||

Has there ever been a study conducted on whether lip prints can be used, like fingerprints, to identify an individual? Does each person have his or her own unique lip print? |
