![]() Some studies show an error rate of over 27% using the AFIS method. But even this method of fingerprint analysis is not perfect. Enter: Automated Fingerprint Identification System or AFIS. One way law enforcement may try to account for potential context bias is to take the element of human error out of the equation. Automated Examinations Don’t Fare So Great For instance, if the examiner is told a lot of background details, the examiner may believe the suspect is guilty and that believe could influence the result of the examination. This may be due to context bias, which means that an examiner may consider other information told to him or her apart from the fingerprint evidence itself. The bottom line is if you have multiple examiners examine a set of fingerprints, they may not form a consensus on whether or not the fingerprints match those of the suspect. The examiners could not agree and their decisions did not match each other. Five examiners were tested, who on average had 17 years of experience. The test was set up so that the examiners looked at two pairs of fingerprints and had to decide whether the fingerprints were a match. Studies have tested groups of fingerprint examiners to see if they all make the same identification and the correct identification. ![]() Experts That Attempt to Make an Identification of a Suspect Based on Fingerprint Analysis May Suffer From Context Effects There are some flaws of fingerprint identification that we’ll review here. Not minding that there are benefits of fingerprint identification, one can still come across its drawbacks. Usually, this form of identification is fast compared to others. The physical attributes of fingerprint identification differ from one person to another. It can be through voice, eye features, fingerprint identification, and so on. Generally, biometric identification occurs when the physical attributes of a person are used in identifying the said person. ![]() It is common to see the advantages of fingerprint identification plastered around the internet, but hard to see the drawbacks.įingerprint identification is a form of biometrics, and like every biometrics method in existence, it is not fool-proof. For a long time, we have been told that fingerprint identification is one of the best forms of identification. ![]()
