Under the implementation of the smart city policy, various cities are in full swing for urban smart construction. As one of the important media for urban construction, LED displays will also be linked to the Internet of Things to create smart interactive displays. But this year, there have been many security incidents in LED display content display across the country, the impact is large or small, so many companies have begun to pay attention to the information security of the content.

 

       

With the advent of the 5G era, the Internet of Things era is approaching, which will be a great challenge for the information transmission of LED displays. Therefore, the content display security of the display screen requires the industry to pay attention to the discussion as soon as possible, and propose cutting-edge solutions to boost the security of the LED display screen as soon as possible.

 

        The Internet of Things, a hidden opportunity, a hidden challenge

 

        As one of the important communication carriers, LED display screen can display in large size, can broadcast information in real time when connected to the network, and convey the characteristics of content in a wide range, which is deeply loved by LED display screen operators. With the continuous research and development and breakthrough of science and technology, the birth of AI technology, and the official commercial use of 5G, people are no longer satisfied with the function of *playing LED display, and put forward the requirements of enabling intelligent interaction and synchronizing linkage, so LED display is moving towards objects. Networking is the inevitable result. Relying on the 5G technology of large bandwidth, high speed and low latency, by linking the big data interface, users can not only remotely control multiple displays at the same time and play synchronously and asynchronously, but also accurately locate the crowd and deliver accurate advertising information, which is conducive to the improvement of advertising effect. Maximization and precision. In order to connect the LED display to the Internet of Things, the corresponding equipment and technology should also be updated. This will drive the LED display industry to deploy the Internet of Things display, and bring another huge opportunity for the display industry to develop rapidly. At this time, if the enterprise lays out in advance, can bear the time cost, and seize the opportunity accurately, it will be possible to become the pioneer of the Internet of Things display.

 

        In the past, in order to catch up with the world level, the LED display industry put R&D and production in the first place, ignoring the safety of content display, resulting in a lack of safety awareness in the early stage of the industry. In a relatively long period of time, companies generally do not set passwords when developing and producing cards, or only set simple and easy-to-guess passwords. Originally, it was to facilitate the operation of LED display operators, but it gave people with ulterior motives an opportunity to take advantage of. , publishing bad content, causing a greater impact. Different from the traditional Internet, the Internet of Things needs to connect a large number of interfaces, data, devices and applications. It faces the real world and can directly affect the real world. Therefore, the display screen that has suffered from content security issues will face more challenges after connecting to the Internet of Things. for serious challenges. Ideally, the content display security can be improved at the beginning of the development of the Internet of Things. However, the reality is that the corresponding content display security system needs to be established after the Internet of Things LED industry chain is established. Networking has a lag, which increases the risk of bad information management and control. Even more so, the LED display industry should pay more attention to content security issues, strive to promote the industry's awareness of content security, and improve the content display security system of LED displays as soon as possible.

 

        Taking the national provisions as an opportunity, following the development trend of content information security

 

        Since the Internet of Things is the country's most important "policy", the country has also held relevant discussion summits to discuss the security mechanism of the Internet of Things. In addition, ten departments including the Ministry of Industry and Information Technology, the Ministry of Education, the Ministry of Human Resources and Social Security recently jointly issued the "Notice on Printing and Distributing Guiding Opinions on Strengthening Industrial Internet Security" (referred to as the Guiding Opinions), stating that by the end of 2020, The industrial Internet security system has been initially established. Among them, the Regulations on Implementing the Responsibilities of Enterprises in accordance with the Law clearly states that it is necessary to establish and improve the risk assessment, safety audit and other systems before and after the networking of key equipment and system platforms, and establish a safety incident reporting and accountability mechanism. Dispose of in accordance with relevant laws and regulations on production safety. The promulgation of the guiding opinions shows the country's determination to strengthen the information security of the industrial Internet, including LED displays, and strengthen the supervision role of Internet information security.

 

        The reception and transmission of most LED display information needs to be sent and received through the Internet. The guidelines include the content display safety of the display screen into the legal provisions, clarify the person responsible for safety and their related responsibilities, and have an impact on the operation and production enterprises of the display screen. And the research and development enterprises that issue cards play a role of supervision, forcibly improve the safety awareness of industry personnel, and effectively promote the display industry to quickly move towards the road of content display security. Although the guidance is not aimed at LED displays, with the development of the general trend, the specifications for the safety of LED display content display will also be promulgated, but it is only a matter of time. Therefore, in terms of legal provisions, the LED display industry should also pay attention to the security of content display.

 

        Multi-pronged approach to promote the formation of content display security system

 

        Although even today, the content display security of the display screen has not formed a stream of consciousness in the industry, but there are always companies in the industry who are keenly aware of this potential trend, and began to develop multiple defensive display control systems a few years ago. , establish a corresponding supervision team, and the national level is to establish a relevant supervision mechanism and other aspects to promote the safe progress of display content display. However, the formation of the content display security system requires the attention and discussion of the whole industry, and it is possible to promote the continuous development and improvement of the content display security system and the control system to cooperate with the rapid development of the LED display industry.

 

        First of all, in terms of control systems, enterprises also need to strengthen the security of permissions on the display. Multiple security keys are set from the sender to the receiver. Before using the display screen, the user must change the password to use it; the operation status of the display screen can be monitored through the cloud platform, and if the operation of the display screen is found to be abnormal, the black screen will be alarmed immediately and an email will be sent to inform the reason, etc. . At present, many enterprises develop control systems for defense in different ways. Enterprises can combine different defense methods to develop control systems with higher security.

 

        Secondly, in terms of management team, a special safety guidance group is established to help LED display operators improve the quality of the industry. The content display of the display is controlled by the LED display operator, but as far as the current LED display operator personnel are concerned, their professionalism, professional ethics and safety awareness are relatively weak, even if the control system of the display is very advanced. , LED display operators may not be able to use them. In terms of installation of display screens or after-sales maintenance, enterprises need to travel many times, increasing the time cost of enterprises. On the other hand, since the operation of the control system with increased security is no longer simple, it has not been understood by some users. Therefore, enterprises need to establish a safety guidance group to regularly conduct skill training for LED display operators, as well as The control system with safety performance is popularized, and the content display safety is slowly infiltrated into the concept of LED display operators, and finally the understanding and support of the operators are obtained. At the national level, it has been analyzed above and will not be mentioned again.

 

        Furthermore, according to the trends and risks of the Internet of Things, Huawei has considered this issue at the beginning of research and development. Since the Internet of Things is based on the 5G network, 5G is considered and implemented from three aspects: standards, equipment, and deployment security. The authentication and encryption have been optimized; the transmission of user data has been changed from plaintext transmission to ciphertext transmission; and the entire user-level data has strengthened the authentication mechanism in terms of anti-tampering and anti-attack. Technology will continue to strengthen and evolve, so it is believed that the security of 5G network in the future will be more powerful, providing network guarantee for the safe display of content on the display screen linked to the Internet of Things. From the country to the enterprise, and then to the network level, various supervisions have laid the foundation for the security system of content display on the screen, but the formation and maturity of the system still requires the cooperation and efforts of the entire industry, legal affairs, and urban management.

 

        The era of the Internet of Things is inevitable, and it is the development trend of the industry to connect the LED display to the Internet of Things. There are still many loopholes in the content display of the display, which has become a major criticism of the display. Now that the technology has caught up with the world level, the corresponding system and quality should also catch up with the world level. It should not be "biased", and it needs to develop in an all-round way, so as to truly achieve a laudable all-round high-quality Chinese enterprise and Chinese products.
