On the morning of June 27, Beijing time, according to motherboard, an American technology media, a programmer recently developed an application called deepnude.As long as you give deepnude a female photo, with the help of neural network technology, the app can automatically "take off" the clothes on the female and show the nude.

At present, deepnude can only process female photos. If the original image has more exposed skin, the better the processing effect will be. When uploading male photos, the final photos will be replaced with female lower body.

Deepnude's official website has been launched. Photos can be processed on the official website. Downloadable windows and Linux applications are also launched on June 23. Users do not need professional knowledge.

The app has a free version and a $50 paid version. There will be large watermarks in the pictures obtained by using the free version. Although the paid version does not have the watermarks in the free version, it will add the "make" (false) seal type mark in the upper left corner of the picture.

Motherboard used dozens of photos to test, and found that if you input the photos of Sports Illustrated Swimsuit, the nude photos are the most realistic.

However, there are still shortcomings in this technology. Most of the photos (especially the low-resolution photos) are processed by deepnude, and the resulting image will have artificial traces; the input cartoon character photos, the resulting image is completely distorted.

Motherboard also contacted the creator of deepnude, a pseudonym for Alberto.

He said the software was based on pix2pix, an open-source algorithm developed by researchers at the University of California, Berkeley, and trained with 10000 nude images of women. This algorithm is similar to the deep fake algorithm of the previous artificial intelligence face changing technology, and also similar to the algorithm used by the unmanned vehicle technology.

"Alberto" said that the software can only be used for female photos at present because female nude images are easier to find on the Internet, but he hopes to create a male version of the software.

He also said he continued the experiment out of "interest" and curiosity. "I'm not a voyeur. I'm a technology enthusiast, "he said." to continue to improve this algorithm, I've learned from the previous lessons (from other start-ups) and economic problems recently. I asked myself if I could get economic returns on this algorithm. That's why I created deepnude. "

But motherboard points out that deep fake has been circulating on the Internet before, but this technology can easily become a tool to hurt women - either using female photos without permission, or spreading pornographic content maliciously on the Internet. Deepnude is equivalent to the evolution of deepfake technology, which is simpler to operate and faster to process.

Katselyn Bowden, the founder of the anti-"Pornography Revenge" organization Badass, said, '"It was a shock to the people. Everyone now has the potential to become a victim of pornography, even if a nude photo is not taken. Such technology should not be open to the public at all."

Daniel Silon (Danielle Citron), a (University of Maryland Carey School of Law) professor at the University of Maryland's Carey School of Law, says DeepNude is undoubtedly invading users' sexual privacy.
