Sex reassignment surgery in Thailand, plastic surgery in South Korea, cosmetic surgery in Japan, and facial beauty in China are also known as the four major “schemes” in Asia.

“Spoofing” is really harmful.
Fake photos are not small
“Photo tricks” reveal the stuff, and most people laugh it off, but editing or disguising photos can really deceive many people.
There is a “non-existent” website abroad. Every time the page is refreshed, a non-existent face photo is automatically generated, which is extremely real.
▲ These people do not exist, they are all synthesized by algorithms.
These photos are all generated by algorithms, and the flaws are almost invisible to the naked eye. Some are modified with photos of real people, and some are made with different facial features of real people.
If you put any photo on the Internet and compile some details of life, most people may believe that this person really exists. Compared with the “photo deception” that can be dismantled by looking carefully, this kind of mixed disguise is harder to see through and more harmful.
In 2017, a foreign user used Deepfake technology to connect the face of “Supergirl” star Guy Gadot to the adult film actress, and uploaded the film to an adult website. It was strongly criticized by the society and many people were worried I am the next victim of this technology.
It’s getting harder and harder to defraud
As technology advances, fake photos and videos are becoming more and more difficult to see through.
The Deepfake technology mentioned above, the algorithm is becoming more and more mature, the face and head joints are more natural, and different expressions can be simulated according to the content of the speech. It has become the preferred technology for fake news, which is difficult to detect with the naked eye.

Previously, Chinese mobile phone manufacturers were exposed to monocular camera photos posing as mobile phone photos. The reason for the “rollover” is because netizens check the EXIF message of the photo, which clearly marked the model of the monocular camera. Later, when some mobile phone manufacturers recruit employees, it is a necessary skill to explicitly request that the EXIF message of the photo be erased or modified.

At present, more and more smartphones take the route of calculation and photography, and automatically “optimize” photos. Some manufacturers even directly modify the key information of the photos, such as adding texture to the moon, which has caused considerable controversy.
Recently, some netizens used PS to check and found a photo on the official Weibo of a certain mobile phone brand. The airplane was from a PS. From the time the photo was sent to the time it was revealed, some netizens did not recognize that the photo was modified, and they also liked it.
Add “seals” to photos and videos
Seeing is being overthrown again and again in the Internet age, and the human eye can easily be deceived by disguised or processed things. Is there any way to completely solve the “photo fraud” problem?
The San Diego startup Truepic developed the Truepic Foresight function.
When shooting, the user can switch the camera to the Secure mode, and a security “seal” will be added to the captured video files. “If someone wants to modify any part of the photo, such as the pixel, date, time, or shooting location… Basically, the seal will be broken, and we will know that the file has been modified after shooting.” said Sharif Hanna, vice president of research and development at Truepic .

In order to improve product safety, the Secure mode will call the 3D depth-of-field lens to record the depth information parameters. “Therefore, you (the user) have complete and transparent information about what happened after the light enters the camera.” As long as someone tampered with photos and videos, It’s easy to find.
Old photos can also be identified
Is it impossible to be certain that photos or videos taken without the Secure mode have been changed? Truepic also develops a picture identification function, which can monitor whether the picture has been changed from multiple angles such as pixel, location, and time.

In order to solve the pain points in the business field, Truepic also developed Vision App for point-to-point secure photo transmission and verification.
If company A needs company B’s document and product photos to be sent to itself, it can send the designated Vision App download URL to company B. The App has a list of files and photos. After company B installs the App, it will use the App to take photos and photos according to the list requirements. It will be automatically uploaded to the cloud, and company A can safely check from its own Vision App to see if the seal is broken. In this way, multiple security guarantees from shooting, transmission to viewing are achieved.
How to use “seal”?
Truepic said that Truepic Foresight technology is initially integrated into mobile phones equipped with Qualcomm Snapdragon 865 processor. When the camera is switched to Secure mode, the photos or videos will be immediately moved from the image sensor to a trusted isolation environment to generate digital Sign and put a security “seal.”

Truepic said it is cooperating with Microsoft, Adobe and media organizations to develop source code software, hoping to popularize it in various software and hardware.
If this technology becomes popular, it is believed to be a big blow to “photographing people,” and it will also cause some troubles. Is the post-photographic processing count as tampering? Is the change in the selfie facial appearance caused by the correction of photo distortion a fake?
Is the “seal” really safe?
Sharif Hanna, the vice president of research and development at Truepic, once said:
After hearing this sentence, the author felt strange and vaguely felt something was wrong.
The history of Internet development proves that no technology or code is perfect. If the “seal” technology is cracked, the “seal” can be faked. Will it cause more harm? It’s like an adult movie that uses Deepfake technology to replace someone else’s face, and this movie has a “seal”, and after the overwhelming public opinion criticizes it, what’s the point of returning the person to innocence?
