The widespread application of RFID will effectively improve the level of urban management [Copy link]

[Abstract] If RFID is to be used in urban management, there are still many problems, such as security and privacy issues. For example, the RFID chip used in the manhole cover has problems such as data reading and updating permissions, reader password protection, and loss risk control.

Editor's note: The in-depth application of the Internet has led to more and more sensitive information being transmitted, so security and privacy issues are hot spots and difficulties in today's Internet applications. Similarly, if RFID is to be applied in-depth in urban management , these problems also exist. Not long ago, a Dutch doctor published a paper entitled "Beware of Your Pet Being Infected with Computer Viruses" at an international academic seminar. He believes that if the RFID chip design for pet management is not thorough, people with ulterior motives can forge specific data and inject it into the chip carried by the pet, thereby affecting its records in the background. In addition, a key issue facing the promotion of RFID in Europe is privacy and security issues. Similarly, these problems also exist in the application of RFID in urban management in China. For example, the RFID chip used in the manhole cover has these problems: Who can read this data? Who can update this data? Is the staff's RFID reader protected by a password? How to control the risk if it is lost?

RFID (radio frequency identification) technology can be applied not only to logistics and retail industries, but also to other industries. Therefore, my country's Ministry of Information Industry has listed it as one of the six special projects during the "Eleventh Five-Year Plan". Although the price, frequency band and coding issues of RFID have troubled its development in the retail and logistics industries, the application of RFID in other fields has already emerged, and some have even achieved good results. For example, the second-generation ID card issued by my country has a built-in RFID chip.

Practice has proved that the application of RFID has achieved very good results in fast data reading and anti-counterfeiting. Of course, RFID, which is known as the world's greatest IT technology revolution since the Internet, is not limited to this - in addition to "managing people", RFID can also "manage things". It is understood that the Shanghai Quality and Technical Supervision Bureau will apply RFID tags to 1 million dangerous chemical cylinders this year; recently, Haidian District of Beijing used RFID to manage various manhole covers in the city, pushing its application to a new height, setting a precedent for RFID to be used in the management of various municipal facilities and attracting the attention of various industries.

The management of dangerous goods, fresh meat, manhole covers, etc. mainly applies the data storage function of RFID, which is similar to putting a nameplate on the monitored object. However, RFID has incomparable advantages over traditional nameplates: data encryption, not easy to forge; data can be modified, easy to supplement information in time and reuse; the tag is small in size and large in capacity, easy to place on the monitored object.

In addition to the "nameplate-type" application, the " sensor-type " application of RFID is also worth paying attention to. At the end of March this year, several Japanese companies jointly announced that they would launch a project called "functional manhole cover" - Japanese researchers integrated sensors with RFID chips to detect various parameters in underground pipelines in real time, such as chemical concentration, temperature, and pressure. When toxic gas leaks, tap water leaks, etc., the system will detect them in time and alarm through the RFID chip.

In addition, some foreign researchers are trying to apply RFID with sensors in the field of disaster relief. One model they envision is to use helicopters or other equipment to spread RFID with sensors on the ruins of houses collapsed due to earthquakes, explosions, hurricanes or other reasons. The sensors can penetrate into the ruins and detect the surrounding temperature, vibration and other information. If there are injured people in the ruins, they may be detected by these sensors, and then the information will be transmitted to rescuers through RFID chips.

As the Internet has developed to this day, people have created a variety of application models—video chats across the entire globe, thousands of computers working together, and watching movies online. Scenes that were only in science fiction films and TV shows a few years ago have gradually entered our lives. The application of RFID also has great potential. As a prototype application under the ubiquitous computing model, video RFID will appear in all aspects of our lives and work.
