S2.3: after the after-sales personnel confirm the after-sales tasks, the application server respectively authorizes the first internet of things device, the second internet of things device and the public internet of things device located on the planned path.
S3: when the after-sales personnel pass through the coverage range of the public Internet of things equipment on the planned path, the application server sends a verification instruction to the after-sales personnel communication equipment, so that the after-sales personnel communication equipment detects the corresponding public Internet of things equipment, and authenticity verification is performed on the way. Optionally, the public internet of things device can also perform short-range communication with the first internet of things device of the after-sales person, and send the communication verification result to the application server via the after-sales person communication device, so as to verify the identity of the after-sales person.
S4: after the after-sales personnel arrive at the user position, the first Internet of things device is detected through the user communication device, the second Internet of things device is detected through the after-sales personnel communication device, and the application server conducts security verification and after-sales service activity authorization according to the detection result. Specifically, the method comprises the following steps:

Example 3
As an improvement or addition to embodiments 1, 2, this embodiment is particularly suitable for data transmission and authentication services by NFC.
NFC technology is an enhanced technology of mutual communication based on Radio Frequency Identification (RFID) technology. In addition to streaming services for transmitting multimedia or files, NFC technology can be used for payment services, licensing services, and authentication services.
The IPv6 address includes a most significant 64-bit prefix address and an Interface Identifier (IID) corresponding to a 64-bit region. The IID may be a device Identification (ID) for identification in the home network. The IPv6 address can provide an upper 64-bit prefix for network identification and form a globally unique address of 128 bits in total. In the case of communication using the NFC technology, a 6-bit node corresponding to an NFC link layer address is an address obtained by logically and temporarily generating a physical address. Therefore, each time a connection between the same devices is attempted, different IIDs are generated from different node IDs. Therefore, whenever a connection is performed, communication is performed using a different IPv6 address.
The aforementioned operating mode, when used for NFC-based services requiring data transmission or authentication by multiple contacts, suffers from the following problems: when there is no IP connection due to external interference or network abnormality, two communication terminals need to perform data transmission anew from the beginning. This may increase the time to authenticate the service, resulting in a poor user experience. More seriously, if external interference or network abnormality is caused by hacking, the retransmitted data has a security risk of being completely acquired by a third party under the condition that the data transmission rule of the internet of things device is not particularly encrypted.
As shown in fig. 3, the protocol stacks of the first and second networked devices in the present invention include: a physical layer, a link layer, an NFC adaptation layer, a network layer and an application layer. The link layer comprises an NFC mapping unit, the link layer node ID is requested through the adaptation layer, and the NFC mapping unit responds to the request sent by the adaptation layer and returns the link layer node ID to the adaptation layer so as to maintain the continuity of the IP connection.
The NFC mapping unit may bind a logical link layer address of NFC to the adaptation layer. For example, the NFC mapping unit may send a 6-bit node ID address of a logical link layer address used to generate an Interface Identifier (IID) for IPv6 to the adaptation layer. The NFC mapping unit is also capable of performing caching of logical link layer addresses to maintain IP continuity of network connection requests at the network layer.
Specifically, the IP connection is checked by the adaptation layer and the check result is sent to the NFC mapping unit. Upon requesting an IP connection, the NFC mapping unit returns the link layer node ID stored in the cache to the adaptation layer. When the link layer node ID does not exist in the cache, the NFC mapping unit generates and stores a new link layer node ID in the cache, and returns the newly generated link layer node ID to the adaptation layer.
Therefore, when the first and second networked devices perform data transmission and authentication service through NFC, the first and second networked devices can be matched with the authentication method, the user is allowed to perform the authentication service in a multi-contact mode, the continuity of IP connection of the networked devices can be effectively maintained, and the efficiency and the safety of the authentication service are improved.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and all such changes or substitutions are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
