Olympic security and management of video surveillance technology

Olympic security draw and to many aspects of high technology, including a video security, also includes chemicals, explosives, also includes the management of the nuclear safety aspects, the Olympic Games Security Committee of experts has done very good work.

Here, I put the video technique to share with you briefly.

1. preamble

First of all, we look back from last year, Shenzhen China Security Forum for some of the changes since its opening.

We can see that from the United States 9.11 terrorist attack, the world has become more fully aware of the importance of the security technology, has great significance for the 2008 Olympic Games finally will be held in Beijing, this is both a historic opportunity for the rejuvenation (because Japan and Korea are organized through the Olympic Games, one enters the international ranks of industrialized countries, and the United States and other countries have tried to thwart our country to host the Olympic Games 2000), but we want to see the Olympic Games are held on security technology the most realistic challenges.

2. review of the Olympic Games security

2.1 1972 Munich Olympics

When it comes to Olympic security problem, we need to recall the history of the Olympic Games security issues.

First we look at the 1972 Munich Olympics. 1972 Germany Government in order to show the new image of Germany after the war, the construction of the new Munich Olympic village, can accommodate more than 10000 athletes representing the new image of Germany after the war.

At that time was already building a very modern facilities, including a high TV Tower, but this is the failure of an Olympic Games.

In 1972, 5 September, the Olympic Games has a scene from the cruel killing of Palestinian terrorists attacked the athletes village, gun, killing 2 Israel athletes, nine hostages kidnapped, the match all stop, Olympic village, confusion, when a terrorist attack, is the world's major television stations broadcast to the world, so the climate of fear. The entire event of all hostages rescued without one, five terrorists and one policeman killed in Germany. At the Olympic Games are Germany police from beginning to end, there is no get terrorists details and images. For example, they do not know the terrorists, what kind of photo, looks like, what few people that last sniper in airport to halt terrorists ambush, the low number of terrorists had two people. After the airport formed a terrorist-fighting, and finally, no one can beat anybody to complete failure of Olympic Games.

2.2 1996 Atlanta Olympic Games

The 1996 Atlanta Olympic Games has also undergone major cases, although on Olympic venues take a strict security measures, but in people exchanged souvenirs of the Olympic Park has undergone intense bombings, there are 2 people dead, 100 injured, the Park of the people scattered flee immediately affected.

Approximately 100 interviews with Olympic journalists are news, journalists to go, the drills, the police will not let this dispatch, results and journalists in conflict, resulting in a very bad influence.

Later, an explosion occurred in the United States FEI substance, and brought a recovery in the future, we can see, there are a lot of nails in it, so can greatly injurious effect, this thing up to now, there is also no effective detection, because in the venue of the Park, did not leave enough evidence to give the image of the police to lead.

2.3 9.11 2001 and the subsequent series of terrorist activities

9.11 2001 and subsequent terrorist events add to this, 9.11 terrorist attacks on the world trade towers, a terrorist organization only spent less than half a million dollars would make the entire United States lost nearly 10000 billion, and terrorists also launched the concurrency type attacks, in the cold war have not damaged the Pentagon had been attacked, there are thousands of people being buried alive, rescue work for dozens of hours.

After the 9.11 also found with anthrax letters for the dissemination of terrorist activities, as part of the public interface of management and the negative image of evidence, to the present case no clues.

In addition to the terrorist attacks on 9.11, most common objectives port, terrorists could use container launched armed attacks (see Figure 10), from small carpet and frozen squid to sports shoes and sports cars, cargo delivery to United States ports of 700 000 containers, United States Customs Service currently can only check one of the 2 per cent.

If you have a container exports of nuclear waste, nuclear bombs, can make the most bustling port paralyzed once shut down the port, the destruction of world trade, resulting in the paralysis of 27 per cent of the economy, resulting in people unemployed, result in the stock market crash. If you do not close it, the risk is great, has always existed. So we can all see that yesterday, President Jiang Zemin held talks with Bush, there is an important issue is that China and the United States reached an agreement on the container control, the meaning of this Protocol is the United States will contribute to China's customs officers in their countries to assist supervision.

All of this tells us that high-tech methods for preventing the normal life of links, has become urgent, so that the Olympic Games after 9.11 security properties are completely different from the history of past any Olympic Games, the Olympic Games of disaster prevention and, in addition to the normal experience of natural disasters, with a terrorist attack in the nature of man-made disasters as well as the associated hazard is thrown into a special need to focus on the issue of a first class, high-tech horror and crime of malignant activities become the prominent characteristics of the activity.

Therefore, and last year's discussions on the issues of security, in contrast, video technologies at the Olympic Games of meaning is clear.

Salt Lake City Winter Olympics 2002 2.4

2002 Winter Olympics in Salt Lake City Japan delegation 20

0 people ready to over 100 gas masks, and prepared the antibiotics, specially prepared a brochure, a guide how to evacuate, 500 war players and 7 million visitors per day, became the host of the heart to stone. In the event, the entire 9.11 Salt Lake City Olympic Games security budget, an additional $ 40 million, and from April of 2001 estimated budget of $ 8300, rose to 3.1 million budget, improves the original plan of 4 times, and the leaves approximately 1.6 million police, secret service, National Guard and security volunteers, such as the composition of the security force, making the Olympic athletes and the proportion of security personnel for the first time in history has reached a height of 1: 6, that is to say 6 personal defence 1 personal, in the United States and technology developed, 60, from State and federal departments form the winter Olympic Games security institutions, become the largest in the history of the United States a security team.

In Salt Lake City Olympic Games with a record of security budget, then spent a lot of high-tech equipment, adding a large number of human resources, including military, National Guard, air traffic control, this is the first time in aviation history.

But the venue has air missiles around deployment, site layout, a large number of security doors, and the mobilization of a police dog and a top to the Federal Bureau of investigation, down to the local police station in a unified command structure.

2.5 2004 Athens Olympic Games priority security issue in the 2004 Athens Games, will also take security issues on the priority status, United States officials claim that terrorist organizations will attack the Athens Olympics N47, this is a dangerous signal because the United States have the advantage of asymmetric information, it can host claimed that in the future, what kind of organization size.

National Committee for the Athens Olympic Games full of security plans for the review, the original is 600 million security plans, last increased to 6 million in funding for high-tech horror and crime prevention as a priority.

So the 2008 Beijing Olympics security will face the daunting challenge of security management, video surveillance technology in this environment, in the integrated management has a decisive role.

3.2008 Beijing Olympics security will face severe challenges, video surveillance technology has a vital role

First of all, it is important for the Chinese nation in the Olympic Games of sensor, control and decision-making basis; and second, we want to mention it is games inside a proactive security measures; and third, it can play a role for the Olympic Games, but also to other major events bring long-term benefits of management, and socialization of a technical measures.

Abroad for video monitoring in the integrated security and validity of community management has been going on for many years, typical of the CCTV, CCTV monitoring system suppression of criminal behavior in public places.

Here is one of the rare data is determined by the United Kingdom, the famous experts have installed camera in public practice in 1990 – 1994 statistics: on public places common delinquency cases, if you installed CCTV monitor system, you can accurately suppression of 21 per cent of crime, if there was once on a public, not the illegal acts of crime acts, will be reduced to 48 per cent; if you use the present high technology advances, the Suppression effect will be more obvious.

So now there are 48 million population in the United Kingdom, there are 50 000 surveillance cameras. London's population does not have a lot in Beijing, London City has more than 20 000 surveillance cameras, the average individual to work every day, in public places is cameras 3 times, the number of times that these measures are effective suppression of crime, terrorist offences of malignant and event video monitoring system is the key, and is the only monitoring and detection means.

For the Olympic Games, the video surveillance system more have a special role.

First of all, for stadiums and security monitoring and organization security, management, playing an important role in monitoring command is easy to spot, natural disasters and terrorism, disasters, and use of heavy rain, hail, earthquakes, and other time creating a disturbance, a tremendous loss.

Stadium tragedy in the history of Brussels is in May 1984, the European Champions Cup finals held in Brussels in Belgium.

Results before the match, fighting for the Championship of Juventus and Liverpool fans of the two teams competing in the camps of disturbances led to the collapse, resulting in a stand of 38 people were killed, more than 300 people were injured, causing football history's largest stadium with tragedy.

For the airport and is also part of the Olympic Games security focus, the Olympic period if the terrorist attacks, resulting in a plane crash, you can make a lot of players play no factory, causing panic among athletes, or even destruction of a country's physical level.

For example, in 1958, England Manchester United flight crash, a team of 23 stars were killed, the Manchester United many years back, it shocked the world football. So for the Olympic Games, often some small countries are not easy to pick out a race team, if airport security issues or problems, the aircraft would have a serious problem, but this issue as a means of protection of non-infringement, with video technology is almost the only way.

The third section is in addition to the conventional we focus on security, focusing on defending the outside stadium command center, administrative departments other than the civil Center sector, and is also the focus of prevention video monitor.

For example, to Center, represented by the Civil Administration Centre, such as Meteorological Bureau, information publishing Center may also be the key target of terrorist attacks, including physical attacks and attacks on the network, and resolve network attacks and physical attacks on basic approaches to employment of image for authentication, if a valid video monitoring technology and proven technology that can identify technical sources of information. About authenticity, video surveillance systems have a greater purpose. In fact, now all of ourFront sensing facilities used in the life of all the facilities and information communication means, all to be reviewed, if there is a problem with the communication of information, or communication channels, will bring great losses.

Cable TV is a typical problem for the month of June 2002, the Falun Gong organization suddenly truncated national direct broadcast satellite signal, broadcast channel Falun Gong, caused a very bad influence.

It tells us that the information published, we had considered secure means, but not as we want to go in the direction of the work, its really broadcast content, what is not in accordance with our time and listings to go, you need to have a very good monitoring tools to manage it. Similarly, our camera is not a true reflection of the signal, this is totally want to monitor, for example, we look at by traffic, an important fleet after, as if everything is normal, but the image can make the video play, play with Falun Gong. Therefore, all front-end sensing facilities and information measures, all to be revisited. Mass of equipment, monitoring the sound and images to high-tech equipment, especially image monitoring, compliance with and the technology is particularly important to make every link in our field of vision and control in the master.

4, video monitoring system development process

With so many security technology, so many video monitoring technology, you will have questions, today's Beijing although spent a lot of effort, a city in General before thousands of cameras, when can we reach there as United Kingdom, London, city of 20 million, the size of the camera, is not to spend too much cost? the answer is obvious, we do not want to go past detours, our approach is to help high tech's latest progress.

When it comes to progress, we must briefly review technology background, video monitoring system development process, it is actually very clear theorization, TV monitoring technology comes from non-broadcast television technology, it is the same as with television broadcast technology, produced at two types of radio and television technology in General is recorded, you can edit, and must comply with the standards of service and rules of play to the public; there is also a non-broadcast, not necessarily comply with DTT, not necessarily with the compression method of radio and television, this kind of thing is what we call non-broadcasting, because it is not subject to the limitations of radio and television broadcasting system, it can be more advanced than radio and television, with better multimedia compression technology, so monitoring technology is a branch of radio and television, there are many military, there are many special purpose Association, China TV, I have a lot of research, but monitoring technology is a typical, non-broadcast television is a branch, you can make extensive use of non-broadcast television's latest results.

5. coding technology development process

When it comes to the latest results, we need to do our little bit depth of speech, want to see the video surveillance of core technologies, i.e. image coding technology.

If after the lecture, leaders and experts on the development of the industry as a whole, from amateur to become professional understanding of live, I think, it is possible to achieve a certain effect. In the past, after which several stages, first, article by JPEG, JPEG, wavelet, ike, motionJPEG, JPEG2000 Wavelet changes, motionJPEG 2000 these classes of image algorithms, these algorithms are based on images of true class characteristic, it does not fit on the virtual image compression and monitor, so it is very big, it's bandwidth is great for storage, not suitable for transport. For example, the background of the wall, it only uses image itself an image photo similarity compressed inside, but the image and the similarity between images, it is no use, to tell you a concept that is not a radio and TV technology is definitely better than a non-broadcast, non-broadcast a bandwidth issue, we can not restricted, you can use the latest technology, the format commonly used radio and television, but compressed bandwidth is too large, the storage space is wasted, so it's also a long delay, the effects are bad, but if the transfer, a frame, a city is wrong, is not suitable for real-time monitoring and network transfer. Now, is very uncertain, use MPEG-4 represented by precise compression technology, suitable for the storage, transmission to a unified solution, the same cases, compression ratio than MPEG-1, MPEG-2 to less than 70% to 80%. Less than 70% to 80% of what it means to be the same size, compression, if the past is a DVD movie, a technology that can MPEG-4 a piece of cake to save four movies, and the delay is very small, for network transmission. For MPEG-4 technology development, it is necessary to say a Word, because society widely misleading, says MPEG-4 is not a standard, so you cannot use, this is absolutely wrong, we can see MPEG-4 draft of work of the Committee, it was in July 1993, to 1 month in 1999 had already become an international standard, and can say that this standard has not MPEG-4 is today's most advanced technology, the next generation of technology can be better than this level then doubles the rate of compression, that is, a single DVD disc, you can save 8 to 10 films, conversely, the same video phone, you only need to spend the last tenth of money. In the future, the future development of the image, because this time the Olympics, so it is necessary to predict, as widely used MPEG-4 next generation technology, is a DVD disc can save more than 10 movies, to a large number of technology save bandwidth technology, this technology is truly fits the Olympic system, suppose we want to build in the city of 20 million camera security network, it is not possible for 20 000 camera back to do a lot of infrastructure construction, luxury, modern buildings are broken up, and then Chief line, full use of existing network cable or wireless communication parties-Can support many number of image transfer, MPEG-4 next generation technology, which is already a mature. In addition, in addition to the network, there is the next generation of image recognition technology. We can expect, in accordance with the technical capacity at the 2008 Olympic Games, intelligent image recognition technology is widely used, and is distributed image recognition algorithms, so that you can make the visit to China by tourists and athletes in the Beijing process do effective management and monitoring, unified in advanced coding technology communications system, this is what we'll be able to see the images in the application of the Olympic Games, we project each front-end is not only the front-end monitoring, as well as social services, front-end, both can do monitoring, but also can drive videoconferencing, almost anyone can do it online on-demand, live webcast, these capabilities, through the activities of the Olympic Games, will be able to establish a long-term technical facilities. Image recognition technology, allows us to effectively determine the authenticity of each image, evidence, or authenticity of information distribution channels, these technologies together, can have video technology more than ever an Olympic, reached a very high price, very effective solutions to security problems.

When it comes to video surveillance technology, there is a very important task, the WTO, for image technology standards, standard grade and classification problems, the problem is very serious, in China, our industry is leading the world of products to the Chinese dumping, various levels of technology are also dumped to China, many of our past that JPEG, MPEG-1, MPEG-2 such technologies are dumped on the market, how beneficial distinguish good or bad, enabling the protection of national industries, so we have high-tech features, also has its own distinctive national features, can do, this work is also very important.

We have also done a study on the classification of the stages, I believe that this combination of MPEG-4 and MPEG-4 next generation technology, may guarantee the user's application and accumulation of Chinese industrial advantage. In staging classification, pay special attention to the three areas, one is the image of the channel than the one the image code processing, compression speed and image recognition, if we go to see the exhibition, you can see, now the MPEG-4 technology has been widely recognized by, swarmed MPEG-4 technology, but if you look at a thing, but what is it good or bad?, mainly to see three things, the first is the channel than looking at its size, with the original image ratio, the ratio of the image to the end of the channel, the second look at its image compression rates, for example, is not able to compress full screen broadcast quality images, or only compact a 320 * 240 of the small size of the image, this is very critical.

Finally, there is substantial and the total resource, these things can help us in the Olympic Games, the different security levels, with different levels of technology, to effectively pull the level, allowing users to achieve the best results.

6 video technology is social security and the Olympic security most important foundation, in conjunction with the Olympics needs, increase investment, will bring enormous social and economic benefits in the Beijing Olympic Games apply advanced video surveillance technology, can bring great benefits to save enormous costs of military systems, capable of saving the cost of the construction of communication lines, can adopt to MPEG-4 technology and next-generation technology, compression, resolution video from Wired to wireless, from fixed to mobile to video monitoring in key areas.

The original information revolution, Bill Gates has put forward an idea, information is everywhere, for security, we need to advocate for such a thing, our video everywhere (our video is everywhere) so that it can guarantee that our patrolmen in the first time get image, often a picture is worth a thousand words, we just know that the United States yesterday serial shootings, detection, then how can the detection, do the long efforts are don't have any clue until the suspect pictures later, three hours were caught. So for humans, the video will always be the most fundamental method, is a non-infringing way, very effective solution to the problem, is to the socialization of the solution to the problem. So we through the introduction of advanced technology, it is perfectly possible in the Beijing Olympic Games, and do the video multimedia information everywhere, whether it's on-demand or monitor, or for social services, and finally make our Beijing Olympic video surveillance in respect of any one in the history of the Olympic Games will not reach the height.

Security of high technology in video technology, is the social security and the Olympic security of one of the most important foundation, needs the Olympics needs, increase investment, will bring enormous social and economic benefits, and is bound to the long-term prosperity of Beijing.
