Fallen Myth - Fingerprints May Not Be Unique

We all believed to have unique fingerprints, but according to recent discoveries, it seems that this is yet to be proved. The discovery shows that members of the same family, share the same fingerprint patterns. Considering a partial fingerprint found on a crime scene, can lead to incriminate the wrong person. Well, it was since 1901 that the police used this "infallible" method. I wonder how many innocent people have been sent to jail for inaccurate reading of their fingerprints. Have you read this news? It seems that many things we gave for granted are finally not so sure. Now I am curious to know if in the future, we will discover that also our voice and our tongue print are not unique.

The police knows that there are similarities between fingerprints, and they want 7 or 8 similar points between 2 fingerprints before attributing it. At this level you cannot make a confusion between 2 persons of the same family, but it explains also why fingerprints found on a scene of crime cannot always be used when they are not neat/complete. Until now I never heard of 2 people having exactly the same fingerprints.

Until now I also did not hear of 2 people with the same fingerprints. I will investigate more, because the media jump easily to conclusions.

@LadyDuck The police can use a fingerprint with only 4 or 5 similarities as a piece of evidence when they have other pieces of evidence against somebody, but it will be presented in court like what it is, a piece of evidence and not a definitive evidence. Some people might not understand it.

@topffer This is what I suspect, people cannot be jailed only on a partial fingerprint found on the scene of the crime.

I have not heard this news. If this is the case, then I am sure other unique to the individual parts will have to be used for identification purposes.
Your earlobes, lip print, tongue print, teeth, and other body parts and traits are just as unique to you as your fingerprints.

You know, while people touch things, I do not believe that a criminal would leave around his/her tongue print. The hear lobes (and shape) the iris and the teeth are also unique you can only use the iris and the ears for very secure ID cards, but they are not useful for the police to trace criminals. If the theory of the unique fingerprints drop, they can only use the DNA.

@Shiva49 Iris is unique, but the iris change with the age and the colour could change if you assume some kind of medications.

Iris is also unique, but it is well know that eye iris changes during lifetime and some diseases can quickly modify the color of the iris. DNA evidence is not foolproof.

I can plant DNA samples, and DNA samples also have other drawbacks. I may arrive at the crime scene and have some of my finger prints there. It does not mean I was not there before, and it does not mean I just arrived. Prints can't be timed. Over the years, they also get contaminated.

@vandana7 This is a good idea, go there several times before the crime, so you can prove that your fingerprints are there because you went there before. While going there to create an alibi, plant DNA evidences collected from other people.

Facial recognition is useful if you are showing your face, I do not believe that criminals will leave their photo on a crime scene. For the crime scene in addition to the fingerprints the DNA test will be useful.

It has long been believed that fingerprints are not unique, just diverse enough to make duplication extremely unlikely or rare.

This is true, but a "partial" fingerprint may be mistaken very easily and I doubt that on a crime scene they can find perfectly stamped fingerprints. If this should be the case, they would be placed there by purpose.

I think it's too easy to compare a partial fingerprint with a database and jump to conclusions. In my opinion there is not a sure method, have you seen the man who was jailed for years because he looked like another man? They should be more careful to check the alibi.

@LadyDuck Maybe they shouldn't use partial fingerprints at all. I think alibis are checked but a good lawyer can convince a jury on little evidence. Our system is said to be the best in the world but still some innocent people go to jail and some criminals remain free.

@LadyDuck He should have use not only one of his fingers. Besides, there's still the alternative code. I can't open mine with fingerprint when my hands are wet, so I use the code.

I would think that the voice could change because of different maladies. I use to be able to sing soprano, now I sing Base. (smoking) changes the vocal chords. And the tongue; depending on what you eat (hot mexican foods) could probably alter it. And considering how much weed pulling and callouses that I've got on my fingers and hands, it wouldn't surprise me that my fingerprints are different from when I went to jail in 2004. I think DNA evidence is probably gonna be the best @LadyDuck .

If you put aside the DNA only the Irisis are unique, but some medications can change the color.

@nanette64 Studies have been conducted to see if the iris is still recognized after a cataract surgery. 25 patients have been analyzed and after surgery six cases were found in which the eye was no more recognizable. It's pretty high.

Well this is not the point, the point is that it seems that people from the same family can have almost identical fingerprints, so if only a portion is used, it is not possible to tell for sure to whom those fingerprints pertain.

@LadyDuck I know they use dental records to identify people. I heard them talking today about finding another method for ID instead of using your social security number. One such comment was an Iris (eye)scan although how serious they are and if it would work is another matter.

@dgobucks226 The iris is supposed to be unique, the color can change with the age and it also changes if you take some medications against glaucoma. The dental records are used to identify people, but I suspect they are not useful to identify criminals, I do not see how they would leave their dental trace during a robbery, different if they kill someone and bite the victim.
