Under the Skin Episode 14 Recap
> Under the Skin Recap
Lin Min, who also studied under Xu Yiduo with Shen Yi, came to Xu Yiduo's home. Looking at the paintings in the studio, she suggested holding a painting exhibition, but Shen Yi felt that doing so had no meaning. Lin Min noticed a painting created by Shen Yi, which Shen Yi had burned seven years ago. From this, it was evident that the painting was a copy made by Xu Yiduo.
Lin Min thus advised Shen Yi that it would be best to paint a real one to replace it, otherwise Xu Yiduo, who copied others' paintings, would be scorned. Shen Yi did not commit after hearing this and left in a hurry with the painting. When Du Cheng visited the gallery, he discovered many paintings by Shen Yi; however, these paintings had been burned by Shen Yi seven years ago.
The gallery owner identified Xu Yiduo from a photo as the person who sold the paintings. Li Han found a video of Xu Yiduo's son, Xu Siwen, on Xu Yiduo's phone. In the video, Xu Siwen requested Xu Yiduo to help him raise a huge sum of money. Du Cheng suspected that Xu Yiduo was selling fake copies of Shen Yi's work to help Xu Siwen raise funds.
Xu Siwen returned to Beijiang, and Shen Yi gave him all of Xu Yiduo's paintings. Xu Siwen decided to sell all the paintings. Shen Yi wanted him to keep some for remembrance, but Xu Siwen believed that Xu Yiduo, who was extremely passionate about painting, did not like him at all, which was why he had been living abroad since adulthood.
Shen Yi asked Xu Siwen if he had received any remittances from Xu Yiduo, and Xu Siwen said he had never received any money from Xu Yiduo. In the interrogation room, Du Cheng told Xu Siwen that Xu Yiduo committed suicide after remitting money to him. Xu Siwen took out all the bank cards under his name and let Du Cheng check them freely. Du Cheng asked Xu Siwen to repeat what he said in the video.
Xu Siwen stated directly that he had very little contact with Xu Yiduo and his wife. After carefully reviewing the video, Shen Yi found that the person in the video was not Xu Siwen. Du Cheng expressed confusion. Shen Yi explained that although the two looked very similar, through micro-expressions that cannot be faked, he could tell the difference between them. By analyzing the light in the video, Shen Yi discovered that the video was synthesized using AI face-swapping technology.
Shen Yi sat in front of Xu Siwen. Xu Siwen wanted to see that video. Shen Yi told Xu Siwen that Xu Yiduo cared about him very much but dared not contact him for fear of disturbing his life, which was why he was tricked. Xu Siwen lowered his head to hide the tears welling up in his eyes. Through case correlation, Du Cheng found that similar fraud cases had occurred many times.
Director Zhang ordered the case to be solved as quickly as possible. Tongcheng, an information security company, was developing AI face-swapping technology. The technical personnel at Tongcheng stated that completing AI face-swapping not only required a large number of photos of the person in the video but also required pre-recording a similar video as the base for face swapping. Li Han found all the fraud videos.
Shen Yi carefully observed and compared them and drew a portrait of the person in the base video. Du Cheng took the portrait and visited people connected to the victims, finally finding a domestic worker named Zhang Xiaoxue. After Du Cheng and Jiang Feng investigated at the domestic service company, they found that the victims of several fraud cases were precisely Zhang Xiaoxue's service clients. Subsequently, Zhang Xiaoxue was brought to the police station.
During the interrogation, Zhang Xiaoxue was a bit nervous but very frank. Furthermore, there was no information related to AI face swapping on Zhang Xiaoxue's computer, and the case reached a deadlock. Li Han suggested looking for clues on the social networking site that Xu Siwen frequently used. After filtering, Li Han found four IP addresses that frequently viewed Xu Siwen's social account, and all four addresses pointed to Zhang Xiaoxue's residence. Zhang Xiaoxue was questioned again.
Shen Yi recalled the signs of a male living there that he had discovered at Zhang Xiaoxue's home. Zhang Xiaoxue explained that she had lived with her ex-boyfriend, Hu Zhifeng, and that they had just broken up. Shen Yi pressed for information about Hu Zhifeng. Zhang Xiaoxue said that Hu Zhifeng was a computer salesman who often traveled for business. Li Han located Hu Zhifeng. Shen Yi learned from Du Cheng that the sentence for fraudsters was not severe.
Just as they were about to take action, Du Cheng found that Shen Yi was gone. At this moment, Shen Yi knocked on Hu Zhifeng's door with a painting.
