According to the people's Daily reported: Recently, have article said, through the two-dimensional bar code scanning software, hide the train ticket two-dimensional code patterns of personal information such as name and identity card number and bare, the information may be illegal for bank card forgery or deception.
Safety code real-name train ticket? The two-dimensional code is what kind of technology? Train tickets used should be how to deal with? This reporter interviewed the Ministry of Railway Transport Bureau relevant person in charge, the local railway authorities and experts.
��Railway special software to read
It is understood, the train ticket is the real-name system, plus the two-dimensional code, purchaser name, identity card number information on the face, the ID number in the replacement of 4 numbers with an asterisk, to protect personal information.
Railway Transport Bureau official responsible for the introduction, the real-name system for ticket early, because of the needs of old and new compatible software, into the passenger information of two-dimensional code is stored according to the industry standard technology, can be read by a two-dimensional code reading software general. At present, the train ticket of two-dimensional code uses strong cryptographic techniques specific to all the information in them (including passenger information) for processing encrypted unified, has strong confidentiality, only through reading software to railway special reading, anti-counterfeiting ability.
����ZhengzhouTrain station duty webmaster Yao Feng said, beginning in 2010, the train ticket will upgrade the barcode was par for a two-dimensional code, two-dimensional code information capacity is larger, but also easy to read, also can better security. The beginning of this year, the national unified encrypted personal information part of train tickets, starting from the train, high-speed rail tickets, various types of tickets are completed encryption. Therefore, now scan the ticket, not a personal information.
����The two-dimensional code information storage capacity
According to the transportation department of the Ministry of railways, the two-dimensional code has large storage capacity, good information literacy and strong information tamper-resistant features. Special encryption processing of into two-dimensional code data, can have certain security function.
The reporter understands, information fault-tolerant ability of two-dimensional code information storage technology has higher, even if some damage, bending, information can still read. But if more than 50% losses, the information will not be able to read.
����Train ticket or don't throw
Zhang Rui think, from the current technical conditions, through the ordinary mobile phone software to read, crack encrypted train tickets, more difficult. But in order to be more safe, suggested that the relevant departments regularly transform encryption mode, it can form a better protection of personal information.
Although the train ticket of two-dimensional code will not disclose personal information, the deputy head of Zhengzhou Railway Station, spokesman Yang Guang reminded passengers to properly handle the waste train ticket. First of all, because the printed name and not complete identity card numbers of dominant information tickets. These may have been used by criminals, so best not to throw the ticket. In addition, the two-dimensional code encryption and decipher the possibility cannot be ruled out completely, so the ticket the two-dimensional code region torn or smear clean conducive to the protection of personal information. Finally, two-dimensional code with fault-tolerance function, even if some damage can also be a normal interpretation of information, it also needs to pay attention to.
��The reporter test:
Using mobile phone software to scan can not see ID number
Yangcheng Evening News according to people's Daily reported: to test the network on "mobile phone can scan two-dimensional code train ticket" rumors, the reporter with Apple's IOS mobile phone and Android mobile phone, download and install 5 more well-known two-dimensional bar code scanning software test. Although mobile phone system is different, different software, but the results show, that several mobile phone software can not read the train ticket of two-dimensional code.
Reporters first apple mobile phone test, in June this year to September, the train ticket of two-dimensional code in mobile phone camera, followed by running different scanning software. "Ding" sound, two-dimensional code is read, in which "1 step scanner", "bar code scanning" and "Quick Scan" scan results is a long string of numbers, "I see" software in addition to display numbers, and train ticket ticket number, consistent with the nominal figures, but its are no ID number. Then scan the mobile phone with Apple's Android mobile phone is similar, only show ticket information, do not display ID number.
Reporters also found last year old ticket, coupon bearing the name, identity card number with 4 number hidden with asterisks. There is a software to scan the results is a series of complex numbers, including complete identity card number. Another piece of software, after scanning can accurately list train ticket number, departure time, the holder ID number.
