Baidu launched blockchain image copyright protection platform Toteng: Controversial


On July 4th, Baidu officially launched its blockchain project official website - Tuteng. According to the official website, Tuteng is a platform based on blockchain technology. Its role is to protect the copyright of image knowledge. Baidu hopes to use blockchain technology to enhance the picture. Copyright protection efficiency.


Specifically, the official website said that after entering the platform, the copyright information of the work will be permanently written into the blockchain. Based on the credibility and incomprehensibility of the blockchain, combined with Baidu's leading artificial intelligence mapping technology, the dissemination of the work can be traced. It can be reprinted, monitored, and changed the traditional image copyright protection mode.

Tuteng platform requires copyright authors to apply for admission. After entering the station, they can carry out original certification and enjoy the diversion and exposure of Baidu. If infringement is found, Tuteng can entrust lawyers to initiate rights protection online and defend rights.


Tuteng encourage photographers, painters, designers, calligraphers and other authors to settle in. After real-name certification, they can upload images to the blockchain technology.

But in some media's views, this is an untrue report, at least not rigorous. Baidu tuteng is not a blockchain, nor can it protect copyright.

Baidu claims to use the blockchain technology to register and confirm the pictures, and to use the characteristics of the blockchain technology to be falsified, to establish the unchangeable right of the picture works.


This logic is correct, and the blockchain is indeed a good player in copyright protection. The blockchain technology is considered to be untamered and transparent because it is a decentralized, distributed system. Information is stored on all nodes, and these nodes belong to each other and do not belong to the same Organization, thereby ensuring that information is not modified by either party.

And there is a premise that this kind of openness and transparency cannot be falsified, that is, no one will control more than 50% of the nodes. If someone controls 51% of the nodes, then the open and transparent nature of the chain is lost, and the controller can tamper with the information on the chain. This is the so-called "51% Attack."

Therefore, a credible blockchain must be open-ended, and there must be many nodes that are not related to each other. Otherwise, this is not called a blockchain, at best, it is called a backup system.


So what are the third parties involved in the blockchain of Baidu Tuteng? Did not say in the report, Baidu has not announced, we have not found out.

If there is no third party involved, only Baidu is acting as an information node. What kind of blockchain is this? This is not a centralization at all, but rather a highly centralized centralization. Even if Baidu gets 10,000 units and 100 million servers to store these picture copyright information separately, it is at best a multi-server backup, which is completely irrelevant to the blockchain. Simply put, it is the copyright information of all the pictures, Baidu has the final interpretation.

So Baidu cannot technically prove that the copyright information of these images has not been tampered with.


Therefore, although many media have reported the Baidu Tuteng and described it as a copyright protection platform based on blockchain technology, some still insist that this is an untrue report, at least not rigorous.

AI technology: can know your nationality by checking your handwriting

The handwriting will reveal identity information, but now AI technology goes a step further, and the handwriting can expose nationality. Researchers have tried to read handwriting through AI to get information about the person's emotions, gender, age, etc. This time their focus has expanded from individual to nationality. The 100 volunteers were from Malaysia, Iran, China, India, and Bangladesh. Researchers asked them to write the same English, and then use a linear distribution (COLD) recognition tool to analyze the shape distribution characteristics of the font, such as straightness, Bending and so on. The results showed that even if the volunteers with the same nationality were written in the country, the handwriting showed a distinct "nationality" character. This is the difference in writing habits made by words. Chinese people who are accustomed to straight strokes of Chinese characters, even if they write Roman letters, will not change the straight-line wr...

The AR-related project investment has exceeded 3 billion U.S. dollars last year. And by 2021, the market is expected to grow to 83 billion U.S. dollars. By the end of 2018, at least 1 billion smartphone users will use augmented reality applications. The VR/AR technology needs to be popular. The public needs to allow users to create and manage VR/AR projects simply and intuitively without leaving home. Just like today we can upload photos, videos or 3D graphics on various social media. As the blockchain, the main task of the Arcona blockchain ecosystem is to provide millions of users with simple and affordable tools for launching their own AR projects around the world. The ecosystem is built on a unique technology platform that can automatically g...
