The question raised by Shi Feng does indeed exist.
In modern society, taking large public transportation requires safety inspections, whether it is trains, airplanes, or even subways and light rails.
Ships are no exception!
The security inspection process at the port includes X-ray scanner detection.
The printing plate is made of high-strength carbide. If a young skateboarder carries the printing plate, it will be detected by an X-ray scanner. Even if it is placed on the body, it will be useless. How about scanning the whole body with a daily metal detector?
When Shi Feng raised the question, the screen wall immediately displayed the security monitoring records.
The corresponding picture shows the young skateboarder passing through the port security check. Although the young skateboarder took off his neck scarf and cap when passing the port security check, the security surveillance camera still did not capture the other person's appearance clearly.
No. 4 Tianji Divine Calculation reminded,"There is something wrong with the other party's glasses. These glasses are equipped with an infrared anti-monitoring device, which interferes with the imaging effect of the camera through infrared rays, so we can only see the area between the other party's eyes and a vast white blank.""
"This is one of the problems."The God of Heaven has figured it out.
Infrared rays are special light. Human eyes cannot see infrared rays, but the camera can capture the infrared beam, so the camera is interfered with.
This phenomenon can be used to capture the face of an Apple phone with a mobile phone camera. Identify the sensor and capture the infrared light in the camera
"The second problem is that the security monitoring record we are watching now is the data information we recovered from the hard drive, and the original security monitoring record has been deleted."Tianji Divine Calculation added.
Shi Feng answered,"If this person didn't have problems, there wouldn't be these abnormal problems, right?"
"right."Tianjishensuan responded,"Please contact the port of Maicon Island and ask them to retrieve the security inspection records at 17:16 pm on May 4th. The inspection records of the X-ray scanner are not connected to the Internet and the other party should not be able to delete them."
"Hold on."After Shi Feng responded, he immediately implemented the investigation plan provided by Tianji Shensuan. He contacted the port security department of Maicon Island and then made his request. In less than five minutes, a short video was sent to Shi Feng via his mobile phone. The video was uploaded to the security inspection server, and after further inspection, it was sent to the data server of the National Security Investigation Agency.
"The corresponding X-ray scanner records have been obtained. Shi Feng reminded.
The video was playing quickly on the screen wall again. The X-ray scanner record of just over a minute was played in less than ten seconds. The divine calculation has found the answer.
An X-ray of a skateboard The scanned picture appears. In the X-ray, the structure of the skateboard is completely seen. A normal skateboard only has two metal structures, the front wheel and the rear wheel, but there is a problem with the internal metal structure of the skateboard youth's skateboard.
The skateboard youth's skateboard is in the X-ray scan A structure similar to the '卌' appeared, and it was an elongated version. The front and rear vertical ones were relatively long and were a metal structure of pulleys. The horizontal metal ones were like the keel structure of a ship, and the two vertical ones in the middle seemed to be metal support structures.
Such a structure At first glance, there is no problem, as if it is a high-end skateboard to prevent the skateboard from breaking under extreme circumstances.
Tianjishensuan directly enlarged the picture, and sent a picture of Mai Kangyuan with a face value of ten yuan and a face value of twenty yuan on the screen, and then with the middle Overlapping comparison of two vertical metal structures
"I think they got past security by hiding the printing plate in their skateboard."Tianji Divine Calculation explained.
This kind of analysis is reasonable!
No!
It should be said that the evidence is conclusive, right?
If the printing plate is not hidden in the skateboard, why should it interfere with the safety monitoring system, and why should the safety monitoring records be deleted?
Huang Guoxiang seconded,"After you Based on the analysis, coupled with the other party's previous behavior of using infrared to interfere with the camera and deleting security monitoring records, I think there is indeed a problem. Have you tracked this person on Hongkang Island?"
When Huang Guoxiang asked, he secretly guessed, 'Who is this No. 4?'
Because of the powerful reasoning and analytical skills shown by Tianji Divine Arithmetic, Huang Guoxiang was full of interest in Tianji Divine Arithmetic, and he even wanted to dig up it. An Liang's corner.
Following Huang Guoxiang's inquiry, the security monitoring record was displayed on the screen wall. The corresponding time label was 18:29 on May 4th.
"We have found the entry record of the other party's landing on the island in the security monitoring system of Hongkang Island."Tianji Shensuan responded.
Huang Guoxiang breathed a sigh of relief,"So have you found this guy now?"
"certainly!"Tianjishensuan responded again
"Where? Huang Guoxiang asked again,"I will immediately arrange for the corresponding personnel to arrest him!""
The National Security Investigation Bureau has standing field personnel on Hongkang Island.
"At the Grand Times Mall."Tianji Shensuan didn't mean to hide it at all,"But something unexpected happened!"
"What accident?"Huang Guoxiang frowned
