The handwriting will reveal identity information, but now AI technology goes a step further, and the handwriting can expose nationality.
Researchers have tried to read handwriting through AI to get information about the person's emotions, gender, age, etc. This time their focus has expanded from individual to nationality.
The 100 volunteers were from Malaysia, Iran, China, India, and Bangladesh. Researchers asked them to write the same English, and then use a linear distribution (COLD) recognition tool to analyze the shape distribution characteristics of the font, such as straightness, Bending and so on.
The results showed that even if the volunteers with the same nationality were written in the country, the handwriting showed a distinct "nationality" character. This is the difference in writing habits made by words. Chinese people who are accustomed to straight strokes of Chinese characters, even if they write Roman letters, will not change the straight-line writing habits. In India and Bangladesh, where the text is more rounded, the fonts they write are more "circular."
By collecting a database of the characteristics of each country's characters and identifying subtle differences in handwriting, the nationality of the writer can be judged. Can AI replace handwriting expert?
This problem is the same as face recognition. AI reading handwriting recognition information also faces the risk of personal privacy violation and identification bias. We introduced skin color and gender bias in face recognition, and handwriting recognition may also lead to prejudice, and it is easy to misjudge people who have a certain writing feature.
Although the researchers suggest that handwriting can be used as a supplement to face recognition technology to help catch criminals, there is still a long way to go before practical applications.
