Fingerprint is one of the most effective evidence for identifying suspects. Everyone knows that each person's fingerprints are different and cannot be repeated. Fingerprints in today's technology-developed society can protect our privacy, payment, etc. The function of visible fingerprints is still a lot.

Modern technology is developed, we have a fingerprint library that can be used for comparison, but in ancient times there was no fingerprint library, and we can see that the fingerprints at that time were very vague and it was difficult to distinguish the difference between the two fingerprints. According to the fingerprint?

In fact, this is a misunderstanding. We really underestimated the wisdom of the ancients. According to the excavation of some archaeological sites, it was discovered that as early as the Qin Dynasty, the ancients had mastered the technique of fingerprint identification. Start using and slowly mature. For the first time, the Song Dynasty used fingerprints to judge the case. In the book, there is a detailed record of how to use fingerprint identification.

Although the fingerprint recognition technology of the ancients is not as good as it is now, it is already very mature. And the age of this technology is still very old. For example, in the bamboo slips of the Qin Dynasty unearthed, there is such a record: "The inner and middle points of the hole have knees, handwritings, knees, and hands everywhere." This sentence shows that when the Qin Dynasty was used, the palms were used to sign. .

After that, fingerprint technology was carried forward, and by the time of the Tang Dynasty, fingerprint technology was very mature. Therefore, in some TV dramas, many of the Tang Dynasty’s graces were replaced by fingerprints. And the first person in the world to propose fingerprint recognition is Jia Gongyan of the Tang Dynasty. The first person to use the fingerprint to break the case was also Chinese. He was the apprentice of the Song Dynasty, Song Ci. His "Washing Book" is the earliest forensic book in the world. It details the basis of the fingerprint case. This book has a high value in history. Editor / Zhao Jing
