Detailed description of the invention
Reference will now be made in detail in the embodiment of the present invention, its illustration is illustrated among accompanying drawing, to the greatest extent its may, all graphic in will be according to similar elements symbol to represent same or similar parts, it must be noted that such graphic pattern for simplifying, and not drawing according to precise proportions.
Fig. 1 is the block chart of a kind of system 10 for certification one RFID reader 100 according to one embodiment of the invention, system 10 comprises RFID reader 100 and a server 107, and RFID reader 100 carries out communication via a mobile communication networking or world-wide web with server 107.
RFID reader 100 can comprise an analogy front end 101, is used for transmitting radio frequency (RF) signal to a RFID label tag, and from this RFID tag radiofrequency signal；Analogy front end 101 is managed by a digital processing unit 102, and is arranged to transmit such RF signal received to digital processing unit 102 and a micro controller unit (Microcontrollerunit, MCU) 103.
Each RFID reader 100 is associated with a unique reader identification (Identification, ID), and each reader identification is associated with a safety code, the reader identification being associated with each reader can be preassigned by manufacturer with this safety code, and be stored in a memorizer of RFID reader 100, such as, this reader identification can be stored in a first memory block 104 of MCU103, and this safety code can be stored in a second memory block 105 of MCU103, in another embodiment of the invention, this reader identification and this safety code also can be stored in the memorizer outside MCU103.
MCU103 is electrically connected at a communication interface 106, communication interface 106 is positioned to allow for RFID reader 100 and carries out communication via a mobile communication networking or world-wide web with server 107, such as, communication interface 106 can comprise the antenna for carrying out communication via a mobile communication networking with server 107, such as one general package formula wireless radio service (Generalpacketradioservice, GPRS) network, a second filial generation (2G) mobile communication network, a third generation (3G) mobile communication network, a forth generation (4G) mobile communication network etc..
According to another embodiment of the present invention, communication interface 106 can comprise hardware for connecting RFID reader 100 to world-wide web via the wireless agreement of connection, fixed network telecommunications or on road.
Server 107 stores the inventory 108 of a reader identification id 01, ID02, ID03, and their safety code SC01, SC02, SC03, and comprise a security key generator 109, security key generator 109 is arranged to produce new safety code, such as, this new safety code can produce based on the safety code that a reader identification is relevant to this.
Fig. 2 is illustrated in the signal of a reader authentication procedure in the system 10 shown in Fig. 1 and transmits flow chart, the most in step 201, one first data comprising this reader identification can be sent to this server 107 via communication interface 106 by RFID reader 100 so that server 107 can compare identification RFID reader 100 by the reader identification this received with the reader identification id 01 in inventory 108, ID02, ID03.
According to one embodiment of the invention, also one second data for this reader of identification that can transmit is to this server 107, and such as, RFID reader 100 may be provided in a NFC formula mobile device, therefore, the second data being transferred into server 107 can comprise the telephone number of this mobile device；In another embodiment, RFID reader 100 may be provided in the arithmetic unit being connected to world-wide web, and in this example, this second data can comprise the Internet protocol suite address (IPaddress) of this arithmetic unit；According in the still another embodiment of the present invention, RFID reader 100 is in the mobile device being implemented in being also connected to world-wide web, and the second data being transferred into server 107 can comprise telephone number and this IP address of this action device simultaneously.
Server 107 is when receiving this data from RFID reader 100, according to the data received in step 202 via inventory 108 identification RFID reader 100, if and RFID reader 100 can be picked out by inventory 108, transmit the request of this relevant safety code of request in step 203 to RFID reader 100；In step 204, in response to the request from server 107, the MCU103 of RFID reader 100 obtains this safety code from second memory block 105, and transmits this safety code to server 107；After receiving this safety code, in step 205, server 107 checks that inventory 108 judges whether this safety code received meets the safety code of the RFID reader being associated with this identification in inventory 108, if this safety code received meets this safety code of the reader being associated with this identification in inventory 108, in step 206, server 107 produces a new safety code, and utilize this new safety code to update this inventory 108, this new safety code is transferred into RFID reader 100 in step 207, and RFID reader 100 utilizes this new safety code replacement to be stored in this safety code in second memory block 105 in a step 208.
On the other hand, if this safety code received does not meets this safety code of the reader being associated with this identification in inventory 108, this reader is judged as a Counterfeit Item, can take action to refusal and is accessed to this server further by this reader.
One embodiment of the certification of RFID reader 100 as above can be before a Producer uses his reader to upload product information, or one consumer use his reader to download before product information to carry out, therefore, this safety code is updated when starting one section of session (session) uploading or downloading product information at this user every time, therefore can increase this information and upload and download the safety of system.
Fig. 3 is illustrated in the signal that in the system 10 shown in Fig. 1, a product information downloads and transmits flow chart, in Fig. 3, the signal for certification RFID reader 100 transmits the signal transmission flow process that flow process is similar in Fig. 2, in addition to the such step in Fig. 2, in order to a user can download product information from server 107, the most in step 301, RFID reader 100 transmits a request to server 107 to download product information.In response to the request from RFID reader 100, server 107 transmits a request of identification information to RFID reader 100, such as reader ID, and separately can include a telephone number of RFID reader 100 and at least one in IP address；Then, carry out the program for certification RFID reader 100 described in reference Fig. 2, after the new safety code that safety code in second memory block 105 is produced by server 107 replaces, RFID reader 100 can start to download product information from server 107 in step 303, in other embodiments in accordance with the invention, the product information asked by RFID reader 100 in step 301 can be transferred into RFID reader 100 together with this new safety code in step 207.
