When thousands of Chinese drinkers walked into the Oktoberfest in the eastern port city of Qingdao in August, a software program scanned their photos.
The person identified as a police wanted list was identified in less than a second.
At the end of three
During the week's event, the authorities arrested 25 people, including one who had fled for 10 years.
In 98% of the cases, the item had a correct facial match, according to police.
The exercise is one of the latest examples of how Beijing uses the latest technology to redefine the limits and scale of large-scale monitoring.
When Chinese President Xi Jinping and the people around him use clean and ruthless-
They rely on these breakthroughs to stop the emergence of different opinions.
This push for loyalty will form a quiet backdrop for this week's Communist Party Congress meeting in Beijing.
When the delegates gathered on October.
After the opening of the conference, they will show an increasingly confident superpower.
Last year, Beijing opened its first major overseas military base in the East African country of Djibouti, deploying warships in the distant Baltic Sea and Atlantic Ocean, and taking a firmer stand in the disputed waters of the South China Sea.
However, all these priorities are dwarfed by the leadership's commitment to keeping control at home.
For a long time, the Chinese government has used all available resources to track the people and suppress different opinions.
Spies and bugging in the early Communist era followed closely.
Technical monitoring of the Internet and social media in China.
China has become the first big country in the world-
A wide range of scale adopters of facial recognition techniques have taken advantage of
Millions of security cameras are increasing across the country.
This technology allows people the country wants to be identified quickly, sometimes collectively.
As part of a separate project, Chinese media reported that researchers have developed projects that can identify individuals hundreds of yards away by walking.
For Chinese citizens, large-scale surveillance has become an unquestionable part of everyday life.
CCTV feed from private security cameras is often broadcast live and continuously on the Internet, watched by curious or prurprur people, and the activities of passers-by are discussed on internet forums, with little regard to privacy.
However, the rulers of Beijing can get more information, as well as data processing tools to ask and analyze this information at any time.
In tracking public behavior online, Beijing has gone further than any other big country.
In 2011, American scholar Rebecca MacKinnon created the term "Internet authoritalism", describing China's active monitoring while blocking many external services such as Facebook.
Since then, government technology has become more and more complex.
Chinese authorities are now able to review social media more quickly and on a larger scale, becoming more effective in preventing searches for controversial topics such as Tibet or the Tiananmen Square massacre.
While many users have found ways to bypass this restriction by using euphemism or plain-to-understand code, Chinese officials are increasingly adept at following up on any discussion about potential strikes or protests, often preparing them to pre-empt
When authorities find things such as online video or audio streams that are becoming increasingly difficult to monitor and control, they want a complete ban.
On 2014, the Chinese government announced a strategy to link the data of each individual and private institution and assign a "social credit score ", "It's basically a way to determine who can have a disruptive impact on society.
Although it will not take effect until 2020, it remains the primary goal of Beijing's security agency and will become easier as technology leaps.
In Western democracies, the deployment of this technology has slowed due to concerns about civil liberties.
However, these doubts are largely absent in the Chinese leadership-in fact, major Chinese companies are increasingly using facial recognition and similar technologies, few regulatory restrictions have slowed their adoption elsewhere.
The enhancement of computing power seems to further enhance their capabilities-especially given that China's development in artificial intelligence and related fields has become a leader.
Another question is whether this is enough to hinder the disagreement.
Beijing faces a series of large-scale Pro
Since 2014, democratic protests in Hong Kong have reached a climax, with tens of thousands taking to the streets this summer after several prominent relatives were imprisoned.
Xi's high-profile anti-corruption campaign-which the Communist Party of China says led to the arrest of millions last year-was partly designed to ease public anger over corruption.
But critics say it has also been used to clear political opponents and competitors and bring in a new generation that is seen to be more loyal to top leaders.
How to further consolidate this power will undoubtedly be one of the hot topics discussed in Congress this week.
However, participants will also be aware that they are also under closer surveillance than ever before, which will only increase in the coming years.
