June 10, according to foreign media reports, recently fingerprint identification technology has made a major breakthrough, Dutch scientists found that by analyzing the contents of the proportion of chemical fingerprint, fingerprint inferred to exist long. Since each person's fingerprints are different, fingerprinting is the most common method of identifying criminals, but current authentication techniques cannot determine when fingerprints are left. Fingerprints are mainly composed of sweat, oil, cholesterol, amino acids, and proteins. Dipuy pointed out that some of these substances will gradually disappear over time, so as long as the proportion of chemicals in the fingerprint is identified, it can be estimated how long the fingerprint has existed. The fingerprinting researcher Di Puyi of the Dutch Forensic Society pointed out that the fingerprint of the neighbor left by the burglary scene pointed out that this fingerprint was left behind by the neighbors or the night of the incident, which is crucial for the investigation. He said: "If you can confirm when the fingerprint is left, you can determine when the suspect has arrived at the scene and what fingerprints are relevant to the case." In addition, the identification process must also take into account the temperature at which the fingerprint is located, as temperature can affect the rate of degradation of fingerprint chemicals. Forensic experts said that with this new technology, fingerprints left in the past one or two to 15 days can be accurately identified. Dupuis pointed out that scientists have tried in the past in the fingerprint analysis of chemical substances, but it was focused on the individual rather than the overall proportion of the number, it ended in failure. He said that the next step is to apply the new technology to the real crime scene to establish a relevant database. It is hoped that the technology will be accepted by the court as evidence in court within one year.
