At present, it is at the peak of Spring Festival ticket purchases. Some posts on the Internet that plagiarize the railway ticketing website 12306 graphic verification code are circulated on the Internet, claiming that the graphical verification code is difficult to identify and some item names have not been heard. In response, the relevant person in charge of 12306 told reporters yesterday that in order to prevent the automatic identification of ticket-tipping software, the relevant graphics have been subjected to technical processing, but in the future some low-recognition pictures will be removed.
Image technology processing for anti-grab ticket software
The verification code of '12306 has already defeated 99% of the nation's ticket buyers. I can't find a way back home. 'In recent days, during the Spring Festival to buy train tickets, many netizens posted a graphical verification code of Tucao 12306. The Internet has even circulated some 'exotic' verification code posts, enumerating questions such as identifying celebrity faces and rare items.
Yesterday, Zhu Jiansheng, deputy director of the Institute of Electronic Computing Technology at the China Academy of Railway Sciences, said that the 12306 ticketing system does not have the 'Extraordinary' verification code for 'identifying celebrity faces', and most of the problems circulated on the Internet are false. 'We will never allow visitors to distinguish between 'orange' and 'orange'. 'Zhu Jiansheng said.
However, there are also some netizens who stated that the verification code is not very clear, resulting in a continuous vote-taking time and missed the purchase of tickets. Zhu Jiansheng stated that before December 15th, the peak of return tickets for the Spring Festival travel, the tens of thousands of pictures in the verification code will be optimized, removing some pictures with low recognition and improving the clarity of the pictures.
' In order to prevent the automatic recognition of the ticket-picking software, we will fine-tune, rotate and cut the picture. This is mainly to find a balance between facilitating ticket purchases and combating ticket rushing software. 'Zhu Jiansheng said.
Some netizens spit some graphic verification codes because of the living environment and habits, 'Southern people do not recognize the northerner's goods, and northerners do not recognize southerner's goods'. Zhu Jiansheng explained that the 12306 graphic verification code selected items that are common in daily life. Because of geographical reasons, 'Southerners have never seen it before or Northerners have not seen it, or they have different local names, and they will all be optimized in the future. Sifting. '
'Graphic verification code is conducive to ordinary people booking'
Zhu Jiansheng introduced that the background data showed that the average waiting time for website ticket purchase this year was only 1.8 seconds, the system was operating stably, and the operating efficiency was greatly improved. At the same time, for the correct recognition rate of the verification code, Zhu Jiansheng said that the probability of correctly filling in the graphic verification code is about 70%.
The relevant analysis at 10:00 on December 9 shows that during this period, a total of 440,000 people entered the graphical verification code, of which 330,000 were entered correctly, and the correct rate was 75%. At the 11th of the day on December 8th, the highest peak of the Spring Festival ticket purchase this year, the correct rate of passenger verification code input was 69%.
'The number of people who signed in was low, and the number of tickets sold successfully increased. This shows that there are fewer inefficiently and repeatedly logged in websites. Zhu Jiansheng stated that past alphanumeric identification codes, some grabbing software and browsers developed by the company are easy to analyze and skip verification steps. In the case where human eye recognition takes 2 seconds, the machine can recognize it in only 0.1 seconds. 'At peak times, this time will also cause passengers to buy tickets. '
Zhu Jiansheng said that image recognition is more convenient for ordinary people. It is easier for the human brain to establish the connection between problems and pictures, and machines have certain difficulties.
Ticketing time reduced to half an hour before driving
According to statistics from China Railway Corporation, since the first day of the Spring Festival holiday ticket issued on November 26, as of December 9th, the railway department had sold 130 million tickets, which was 9% higher than the same period of last year. Nearly 90% of the tickets were successfully booked online.
This year, the railway department will also take a number of new measures to facilitate student and migrant workers and other groups to purchase tickets. At present, the railway department has cumulatively sold 8.048 million student tickets before the pre-holiday day, and has also fulfilled the round-trip ticket plan for student groups that are reported by the institutions through the Internet.
'From today onwards, students who have not purchased tickets and have not participated in the unified ticketing by the institutions can still purchase student round-trip tickets from January 10 to February 29 next year through various channels of the railway. Huang Xin, deputy director of the Operation Department of China Railway Corporation Transportation Bureau, said.
In order to facilitate the purchase of tickets by the migrant workers, the railway department has cancelled the limitation of 5 persons this year. A single passenger can also apply for a ticket purchase plan. At present, the railway department is accepting round-the-clock ticket purchase plans submitted by labor companies and leisure workers during the Spring Festival. The plan will be redeemed on December 15.
From December 16 to December 25, employment companies can register for migrant worker group tickets for website search results. The scattered migrant workers can use the mobile phone short message prompts to pay for and collect tickets at any window on the railway with the original ID of the second-generation ID card.
In addition, the railway department will also adjust Internet ticketing time from no later than 2 hours before driving to no later than 30 minutes before driving. At the same time, it also introduced change-to-stop services and provided online lift services on trains.
Verification code technology company denies accuracy 8%
The person in charge of the company responded to the challenge and said that the graphic verification code can withstand most of the cattle; the gallery will continue to increase
As the Spring Festival grabs the tide of votes, the graphical verification code launched by the 12306 ticketing system suffers from Tuba. Some netizens will target the companies that provide verification services for the system. They questioned how the 'graphic verification code' approach did not completely block the cattle and posted them. Cattle party purchase order chart. Another netizen posted that this technology is not original but copied Google. In addition, there are netizens that the official did not disclose the details of the relevant tender projects and fees.
It is Hangzhou MicroTouch Technology Co., Ltd. that provides the graphical verification code service for the 12306 system. In addition to the railway 12306, the user column also includes icons such as 'China Post' and 'Jinshan Fast Disk'.
The company's industrial and commercial information shows that Hangzhou Microtouch Technology Co., Ltd. was established in September 2012 and began operations with a registered capital of RMB 300,000. The legal representative is Song Chao. According to a search by the Beijing News reporter, there is a company named Beijing Touch Internet Technology Co., Ltd. under Song Chaoming, which was established on December 3 with a registered capital of 1 million yuan.
As for the doubts of netizens, Song Chao said yesterday that, in addition to occasionally more difficult to identify images, the graphical verification code can withstand most of the cattle.
1 graphics verification code database leak?
The number of pictures is not fixed, it is a dynamic increase
According to insiders, the 12306 official website launched a graphical verification code, originally intended to intercept technical cattle, 'but in fact only intercepted part. '
According to its disclosure, after the launch of the graphic verification code, some people stole the background verification database and established a 'coding platform'. When the cattle purchase tickets, just pass the coding platform to bypass the graphical verification code. It said that the code recognition rate of the current coding platform has exceeded 90%.
According to him, every time the yak coded once, it would take 1 to 5 points to pay for the coding platform, and for every purchase of a ticket, the cattle usually need to code more than ten or twenty times, and more often than one hundred. Times.
At the same time, the 360 ​​browser also announced recently that it has completely broken through the 12306 graphics verification code to achieve automatic identification technology, and for the first time published 581 kinds of 12306 graphics verification code big data.
In this regard, Song Chao, head of Hangzhou Micro Touch Technology Co., Ltd., said that the number of pictures is not a fixed number, and it is a process of continuous dynamic growth. It will 'update itself through the use of user data. 'He introduced, the system will capture a large number of pictures every day,' through the user's choice, the process of user verification, will automatically help the system through the machine learning to obtain a new gallery, security will increase with the amount of verification and self-improvement. At present, we have automatically identified nearly 10 million accurate pictures through the verification system. Each verification of the user is helping the artificial intelligence to contribute to the field of image recognition and train machine learning. '
2 One-time accurate recognition rate is only 8%?
The network transmits the 'Extraordinary' verification code for PS synthesis; the back-end data show a very high success rate
According to the big data provided by the 360 ​​browser, the accuracy of one-time input of the ticket verification code of the 12306 website is 8%, the accuracy of the two-time input is 27%, and the accuracy of inputting three or more times is 65%.
360 technical personnel said that when the 12306 launched a complex verification code, they focused on statistics through technical means and found that its identification pass rate was in an unstable state. Part of the unrecognizable pictures and unsuitable image processing by the 12306 caused the overall recognition rate to decrease. In some periods, the recognition rate was even less than 5%.
According to a technical person, technically speaking, this method has a certain degree of innovation, complex graphic verification code, and raises the threshold for automatic identification. However, its picture quality is poor, and there are some pictures that are uncommon and confusing. And inappropriate image processing, resulting in poor user experience. Objectively speaking, the 12306 complex verification code has indeed played a certain role in combating the yellow cattle. For example, it performs fuzzy granulation processing on some verification codes to prevent the cattle from using special ticket-picking software to brush tickets.
In response to the low success rate of authentication codes proposed by some internet companies, Song Chao stated that the company’s products that touch authentication codes are relatively mature and the success rate of back-end data display is very high. Apart from some particularly difficult-to-recognize pictures, some are The 'Extraordinary' verification code pictures are almost all made by PS synthesis.
3 Changes in equity before and after cooperation with the railway sector?
It’s normal for startup companies to leave someone and join
Some netizens pointed out that the beginning of using the graphical verification code for the railway system was around March of this year. As the technology provider, the company’s stock rights immediately changed before and after the railway department began to use the graphical verification code. 'Approximately one person was deleted and one person was added. . '
Song Chao received an interview with the media in May this year that each startup company will experience a bottleneck. Before a certain period of time, the company's development was difficult and the capital flow became tense. A classmate could not see hope and skipped.
"The startups are very bitter, and some are leaving. There are also reasons why they are willing to join together and work hard towards the goal." He said, "Backyard can support more than 300 million requests a day," the system must be enhanced over previous years. , 'They are still attracting more technical personnel to join in, to complete the protection of user information security protection in the verification of security, account security, password security and behavioral security.
4 Does the graphic verification code technology copy Google?
Claiming to present iconic verification code in 2012, proposed by Google in 2015
Some netizens said that this kind of graphics verification code technology is not original, but copying Google.
According to several media reports, in the year of 2011, Song Chao discovered the verification code 'BUG' when he graduated from Harbin Engineering University. After that, Song Chao and several other peers with his own learning technology developed a 'touch verification code'. And the "touch cloud security system" to participate in the new media venture contest winners, get millions of dollars in angel investment, after which he dropped out of school and established Hangzhou MicroTouch Technology Co., Ltd..
According to reports, “touch verification code†is to replace the blurred background in the traditional verification code with a clear picture. The above is a randomly arranged identification (Chinese characters, numbers, English letters, meaningful icons, etc.), and the user clicks (as required). Or touch) the location specified on the picture to complete the verification. The project already has 3 patents.
'We launched iconic verification codes, graphic verification codes and swipe verification codes, and rotary verification codes in 2012, which combine behavioral security control and has been optimized and evolved. There are currently more than 50,000 websites using touch services. , Google is the icon verification that was proposed at the beginning of 2015. Didn't it mean that we copied them? “Song Chao said that micro-touch started early in the development of tap authentication codes. Since 2012, it has been operating in a company. Now it has established a company in Beijing, focusing on user information security and privacy security.

If the sample is enough to save the crack
Internet expert Shi Wenyong believes that the graphical verification code technology is indeed more complicated than the usual text verification, but he does not think that graphical verification can play a role. 'Some software can automatically pair all the pictures that appear, so it's hard to say that it can prevent the cattle. Brush tickets. '
He said that some ticket purchasers will also seek the help of software if the use of relevant software to brush tickets can be faster than regular ticket purchases.
'Many people have fewer votes, and some technicians can buy votes earlier than individuals, and any tool can't prevent it. 'The security founder and CEO Ruan Zhigang said that the actual test shows that with the help of Google and other giants of intelligent mapping technology, can identify the meaning of most pictures, the accuracy rate of 85%, if the collection of sample data is large enough, there is a crack The possibility of a graphical verification code, once the graphical verification code is hacked, they can continue to brush votes.
He said that indeed the graphical verification code increases the difficulty of recognition, but there is no revolutionary change in the difficulty of cracking, and it should establish a variety of joint mechanisms to resist the behavior of brushing yellow cattle.

Is booking a summit '瘫痪'?
Can carry tens of thousands of visits per second, running smoothly during peak hours
Yesterday, relevant personnel of China Academy of Railway Sciences visited the background of the 12306 ticketing system. On the display screen of the monitoring hall, the real-time operation data of the two production centers of the Railway Corporation and the Institute of Iron and Steel are displayed. These data include the number of real-time logins of websites, mobile phone APPs, payment status of ticket purchases, ticket collection status of stations and so on.
During the Spring Festival season, the ticketing data will show a spike every half an hour. This shows the peak ticket purchases during 21 ticketing hours every day. Zhu Jiansheng, deputy director of the Institute of Electronic Computing Technology at the China Academy of Railway Sciences, told reporters that the system started operating at 7:00 every day and continued to stop paying until 24:00.
Zhu Jiansheng introduced that the 12306 website can withstand tens of thousands of visits per second and keep the system running smoothly. At the peak of the December 8th, the 16-hour visits throughout the day were 36 million, and less than 1,000 visits per second. This was entirely within the scope of the website design. '
At the same time, according to the relevant data of the 12306 back-end system, this year's 12306 website logged in 36 million users on the peak of the December 8th, and the number of successful ticket purchases by passengers was 6.087 million. Last year during the peak period of ticket purchase, there were 56 million logged-in users and only 5.63 million tickets were sold.
Why is it still hard to get a ticket?
Increasing Train Adjustment Operation to Solve the Contradiction between Supply and Demand
Yesterday, the reporter asked the relevant person in charge of 12306. For the previous media reports, 'The reporter could not buy the ticket, and the cattle can still buy the ticket,' the relevant person in charge said that the graphical verification code prevented the ox from seizing the ticket to a certain extent. However, the Cattle may use more bandwidth and faster speeds to professionally grab votes.
'Some third-party platforms and software also use unregistered real-name passenger information to smuggle tickets and draw votes. The railway department will take relevant measures on this matter. 'Huang Xin also reminded passengers not to use these platforms to buy tickets, so as to avoid disclosure of personal information.
Zhu Jiansheng said that the background is still technically monitoring some attempts to decipher the 12306 graphics verification code, and in the future does not rule out upgrading the verification code system again.
The railway department introduced that improving railway capacity is an important direction that ultimately resolves the contradiction between supply and demand. In the Spring Festival this year, the railway department opened 3,488 pairs of passenger trains per day, an increase of 14.5% over the Spring Festival of 2015. Among them, 3048 pairs of passenger trains are scheduled, and 440 pairs of passenger trains are added during the Spring Festival.
Starting from the 16th of tomorrow, the railway will increase the number of trains. As far as passengers who have not bought the tickets, there is no need to worry about it!
The brake disc is composed of steel plate, adhesive heat insulation layer and friction block. The steel plate is applied to resist rust. In the painting process, smt-4 furnace temperature tracker is used to detect the temperature distribution in the coating process to guarantee the quality. The heat insulation layer is composed of non-heat transfer materials for the purpose of heat insulation. The friction block is composed of friction materials and adhesives. When braking, it is squeezed on the brake disc or brake drum to generate friction, so as to achieve the purpose of decelerating the brake. As a result of friction, the friction block will be worn gradually, generally speaking, the lower the cost of brake block wear faster.
