The manager can also operate the NFC terminal through the background management platform, for example: adding new user information, logging off old user information, recharging, freezing, permission changing and the like.
And (4) security policy: firstly, a field is arranged in the data code and used for storing the TOKEN, the TOKEN is time-efficient, when face recognition is carried out, the background management platform generates a TOKEN according to the name of a user, meanwhile, the TOKEN is written into the NFC terminal, the TOKEN exceeds the time efficiency, the TOKEN is refreshed if face recognition is not carried out again, and then the current NFC terminal can be frozen.
Secondly, under the condition that the NFC terminal is lost, the user can remotely freeze through the client APP to prevent unnecessary loss
The NFC terminal embeds there is the battery to be equipped with fingerprint identification ware, fingerprint identification ware passes through battery powered, and the NFC terminal needs the user to carry out the fingerprint unblock when using, and the unblock time sets up a relatively short inefficacy, if: 30 seconds, after the NFC terminal is used, the NFC terminal is automatically locked, even if the NFC terminal is lost, a user cannot find the NFC terminal in time, other people can not use the NFC terminal when picking up the NFC terminal, and property loss is avoided.
The working principle is as follows:
firstly, the general anti-copy NFC label management system requires that a code stream written in an NFC label needs to accord with a general code stream protocol, a storage area 1 of an NFC chip writes a 32-bit secret key generated by encrypting a 6-bit sequence number through an aes128 algorithm and a 6-bit serial number, the serial number is written in by an NFC chip original factory through a special tool, and meanwhile, the serial number is recorded in a label background. The 6-bit serial number is randomly generated by the background management platform to be used for each NFC card, and the second part of the code stream stores the usage scene code stream, such as: the current label is used at the room heater, and function ID is 01 so, is for allowing APP to read and write the position by 1 byte in function ID's data bit, and the sign is whether this label supports special APP to read and write, and 00 is for not supporting, and 01 is for supporting. The user ID uniquely identifies the NFC label, and after the user ID interacts with the card reader, the NFC label and other data in the code stream are uploaded to a background together. If the NFC label has other application scenes, the storage area can write code streams of other functional IDs according to actual conditions until the maximum capacity allowed by the label is exceeded. At this time, when the NFC tag interacts with the card reader/mobile phone that also conforms to the general code stream protocol, the card reader first starts the decryption SDK, decodes the 32-bit key in the tag region 1, compares the 6-bit serial number after decryption is successful with the backup storage of the background management platform, and if the decryption is not successful or is unsuccessful, the card reader prompts the user that the user is an illegal NFC terminal, and prohibits any read-write use of the NFC terminal. If the code stream is matched with the function ID, the card reader starts a built-in code stream analyzer module, polling is carried out on the using scene code stream to read the residual code stream data, each analyzed function ID is compared with the function ID built in the card reader, if the card reader is a water card reader, and the NFC label code stream also has the function ID, the water card reader can normally identify the label. If the current user finds that the hot water balance in the card is insufficient, the user finds that the code stream is read by using the special APP, the allowable APP read-write bit in the data bit is 1, and if the NFC driving module is started by the mobile phone end, the user is allowed to directly recharge the card through the special APP. The card reader is thus a meal card reader and the tag will be identified for use with a meal card. Under the support of the universal code stream protocol, the universality of one card with multiple purposes is realized, and the data in the card is prevented from being copied and falsified maliciously.
The invention overcomes the defects that the traditional NFC management scheme can not effectively prevent copying and tampering and the construction cost is too high due to the separation of a plurality of backstage, meets various application scenes of one card with multiple purposes, anti-theft and unified backstage and reading and writing of APP, such as reporting user data in a card to an NFC label management platform cloud server after safety verification, and can accurately display and read and write the card data on the APP. The scheme is applied to actual products at present, so that the labor and the time cost are greatly saved, and data statistics and later maintenance are facilitated.
An embodiment discloses a management method of an NFC label, and the implementation of the management method is based on the anti-copy NFC label management system based on the Internet of things.
Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the present invention.
