Does Tik Tok need to worry about the privacy of face data when it opens the same special effects to external enterprises? (how does Tik Tok shoot others with the same paragraph? )

Every reporter: Wang Ziwei Every editor: Liu Xuemei

Remember the special effects of Journey to the West TV series "The Birth of the Stone Monkey" in the 1980s? I watched it with relish when I was a child. Now it seems that the special effects technology based on matting is really full of loopholes. Nowadays, special effects have been iterated, such as the expression special effects of "Thanos" in The Avengers.

Now, ordinary mobile phone users are very comfortable with the special effects technology used in movies and TV in the past. The stickers, expressions and makeup you use on Tik Tok, Xiaoyan camera and other apps are actually popular applications of special effects technology. In a word, special effects technology is stupid.

On July 28th, Volcano Engine, one of the directors of special effects players, announced that he would open tens of thousands of Tik Tok special effects of the same model to enterprise users.

The National Business Daily reporter learned that the special effects of this opening include popular props used by Tik Tok users, such as cartoon faces and 3D monkey brothers. Volcano Engine Resource Mall also provides special effects shooting resources, editing resources and template resources of the same model as Tik Tok, which enterprises can choose to use according to the heat and type.

At the same time, regarding the concern that Volcano Engine's processing of massive face data will lead to the disclosure of personal privacy data, the company responded that the special effects did not use face recognition technology, but detected the key points of the face locally, and the detected data would not be uploaded to the server.

Volcano Engine said that its suite of special effects tools is also open to corporate users. This means that a designer can produce a 3D special effect in only 5 days, and the work efficiency is greatly improved.

Is privacy a problem? Today, Volcano Engine also disclosed the Tik Tok special effects data report for the first time. The report shows that in the first half of 2002 100, Tik Tok platform launched more than100 new special effects every day on average; On average, out of every five contributions, 1 uses special effects.

GAN technology, that is, the technology of generating confrontation network, and the popular videos such as "face changing" on the network are based on this technology. Volcano Engine's massive face data will inevitably lead to concerns about the disclosure of personal privacy data. In addition, the special effects such as changing face, aging and makeup realized after using GAN technology also make people question whether the design is deeply forged.

In this regard, Yang Hui said that special effects do not use face recognition technology to detect faces, but locally detect key points of faces. In short, the detection data will not be uploaded to the server through the point recognition appearance. In addition, the special effects such as aging and cartoon face realized by using GAN technology are also the display effects of users' own images, which are essentially different from deep forgery of others.

"Special effects are not only a technology, but also a project." Yang Hui said that there is a perfect engineering system behind the special effects of Tik Tok, including modular components, flexible and customizable resource allocation capabilities, and compatibility and adaptation to different systems and screens with different resolutions. The data shows that the program interface crash rate of Tik Tok special effects is less than one in 100,000, and the stability is leading in the industry.

Service companies will encounter customization needs. Yang Hui, an expert in special effects technology in Volcano Engine, said that it is inevitable to meet individual needs, but customization does not necessarily mean low ROI.

"Although personal needs will be met in details, the needs of an industry still have certain * * *. Many times, a certain customization ability we have done before will eventually become everyone's demand. From an industry perspective, earlier exposure to differentiated needs can help our internal business build a better foundation, and it will also promote the progress of our internal business in reverse. " He said.

Wang Yunhui, head of Tik Tok Design Center, said that for C-end users, the original intention of Tik Tok to provide special effects is to lower the threshold of short video shooting and help users express themselves better. It is understood that Tik Tok's self-built special effects team has reached 100, and an open platform for special effects has been launched to cooperate with external designers. Wang Yunhui also revealed that Volcano Engine's special effects have been opened to ordinary users.

As an enterprise-level intelligent technology service platform behind ByteDance, ByteDance's "capability export" business not only supports internal products of companies such as Tik Tok and Today's Headlines, but also opens to external enterprises, providing customers with products and services such as special effects creation toolkits, customized algorithms, engineering deployment and docking debugging.

Behind this, ByteDance is opening its core technologies such as recommendation algorithm, data analysis and artificial intelligence to corporate customers through Volcano Engine. This is the latest move of ByteDance to enter the enterprise service field after launching the enterprise collaboration tool "Flying Book".

On June 10, Volcano Engine made his debut, comprehensively expounded his business philosophy and product logic, and opened technical tools and architecture based on data-driven concept to enterprises.

With the development of mobile Internet, the use of special effects such as AR and VR is no longer limited to long and short videos, but also widely used in e-commerce, social networks, cultural tourism, games, education, intelligent hardware and other different fields.

At present, in terms of visual AI, there are many players on the market who provide special effects technology. Such as "CV Four Little Dragons" Shangtang Technology, Defiance Technology, Yi Tu Technology and Congyun Technology. The four major players involved in security, finance, Internet of Things, driverless and other scenes entered earlier. In addition, the four companies are also ahead of Volcano Engine in terms of team size and financing scale.

What are the similarities and differences between volcanic engines and "Four Little Dragons"? What are the advantages?

Yang Hui is very honest about this reply. He said that there is no essential difference between Volcano Engine's special effects technology and competing products in terms of service content. "Whether special effects are popular or not is easy to receive feedback, which can promote business optimization algorithms. In addition, our richer internal business scenarios can promote the continuous improvement of the adaptability of our algorithms. " Yang Hui said.

At present, Volcano Engine's special effects technology has served many enterprises, such as singing bar, understanding the ball emperor, Hisense and so on. Yang Hui believes that the accelerated popularization of 5G will further expand the application space of special effects.

With the help of special effects technology, a designer can produce a 3D special effect in only five days, which is far from greatly improving work efficiency. That may mean that the product packages exported by companies such as Volcano Engine will change many industries that seem to have certain barriers at present.
