On August 19, 2016, Shenzhen International RFID World Conference on Application Innovation, sponsored by IOTC, organized by MediaTek, Shenzhen Industry Standard Alliance of IoT, and Guangdong IOT Public Technology Support Center, was held in Shenzhen Convention & Exhibition Center Hall 3 successfully held. This meeting attracted a large number of industry elites, experts and scholars to participate. Among them, Mr. Wang Lijian, Technical Director of China Electronics Standardization Institute, gave a speech entitled "Development and Application of Internet of Things Identification Technology" to the participants.

What is OID? Literally translatable as object identifier. As an identifier in the Internet of Things, the OID identification system is an identifier jointly released by the three major international standardization organizations such as ISO, IEC and ITU. To achieve the object networking, the forefront of technology is perception, and then access the network, and determine the location of objects.

Understand the concept of "metacognition" before understanding OID. That is, the meta-tag is the tag of the tag, and the tag is mapped. This concept is a result of long-standing research by relevant international agencies. For example, our Ministry of Health: OID (1.2.156.10011), of which 156 represents China, the 156 code is given by international organizations.

According to Wang, the application areas of OID include information security, medical treatment, network management, interoperability solutions of standards, organizations and heterogeneous labeling systems. With the development of the Internet of Things, cloud computing and big data, the current OID registrations have risen in millions.

For the OID system, many experts emphasize encoding To solve the interoperability, compatibility and international standards, Wang believes that this is actually a false proposition to the telephone number system, for example, the world's most secure system is likely to be The telephone system is different for each country, province and city, but this does not affect each other's calls. If you must force the establishment of a uniform code, it means you must give up self-management, let others manage for you, can not guarantee safety. On the contrary, OID can magically establish the interconnection between "isolated islands of information".

It is reported that the current international identification system includes GS1, Handle and OID. Among them, GS1 is promoted by the EPCglobal Commercial Company in the United States. Its service targets are international large-scale retailers and logistics enterprises (such as Wal-Mart and Metro) and technology providers (such as Microsoft, IBM and Cisco) Information security risks; Handle is a naming service system created by the American Association for Research and Innovation, which mainly identifies publications / digital content objects such as periodicals, literature, books and the like, and is applied to libraries, universities, laboratories, etc. The technologies are controlled by foreign enterprises and exist similarly OID is a global identification system jointly promoted by ISO / IEC and ITU international agencies and covering more than 200 countries in the world; technology fields such as computers, mobile communications and short-range wireless communications; and global geographic facilities, people and goods , Logistics and transportation, finance and other applications.

The domestic identification system mainly includes Ecode and OID. The former is a closed system of identification within the country. There is no international organization that admits it and no independent technology. The latter is an independent research and development, independent management of our country, which is maturely applied and safe and reliable.

Wang reported in the report that ISO / IEC and ITU international agencies jointly developed and promulgated more than 30 international standards for OID identification naming rules, distribution programs, transmission coding, analytical management system and other content specifications to achieve a formal, no Ambiguity and precise unique identification mechanism to identify different objects. However, OID is not closed and is open. Under the precondition of complying with international standards, OIDs are allowed to independently develop and develop related technologies. For example, South Korea's Mcode, Japan's UID, the international GS1 organizations, while maintaining the corresponding technical independence, are incorporated into the OID identification system.

It is understood that in 2006, the Ministry of Information Industry approved the establishment of a national OID registration center, on behalf of the national management ISO, ISO-ITU Chinese OID branch below, is responsible for the registration, management and maintenance of domestic OID and international filing work, on behalf of China participates in standardization activities. Wang told reporters that so far, based on the identification of Internet of Things approved by the state authorities to set up support agencies only this one, can be justifiably flatter the national standard with the IOT logo is only the OID. If the enterprise has relevant intellectual property rights in technology and patents and is willing to formulate national standards and industry standards on its own, the standard institutes can help implement the national standards and industry standards formulation plan.
