Benefits of technology
[0008]An aspect of embodiments of the present invention is to solve at least the above problem or disadvantage and to provide at least the advantages described below. Accordingly, an aspect of embodiments of the present invention is to provide an RFID tag reading system including an RFID tag, which guarantees individual privacy by transmitting tag data only when a preset password is input, and reinforcing security of the tag data, and an RFID reader, and a method thereof.
[0035]As described above, an RFID tag according to the present invention is input with a password, tag data are transmitted to an RFID reader only when the password is the same as a password from the RFID reader. Accordingly, the security is reinforced, and individual privacy can be protected. In addition, in case that somebody tries tag reading, the owner of the tag can instantly notice by an alarm message or an alarm signal that the tag reading is tried. An RFID system according to the present invention can be applied to diverse environments such as a shopping system or a content providing system.
Problems solved by technology
As a result, the security of the tag data stored in the tag is not guaranteed.
Therefore, the privacy of the user having the product can be invaded.

Embodiment Construction
[0053]Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawing figures.
[0054]FIG. 1 is a schematic diagram illustrating the configuration of an RFID tag reading system according to an exemplary embodiment of the present invention. According to FIG. 1, the RFID tag reading system includes a tag 100 and a plurality of readers 200_1 and 200_2.
[0055]The tag 100 contains a memory (not shown). The memory stores tag data and a pre-registered first password. The tag data are diverse information (product information, personal information and a tag ID) on a product (or a tag owner) which the tag 100 is attached to.
[0056]If a first reader 200_1 of the plurality of readers transmits a tag data transmission request signal (a), the tag 100 requests a password transmission to the first reader 200_1 (b). The tag data transmission request signal may be a carrier signal containing a message which requests tag data transmission,...

Provided is a RFID tag with enhanced security. The tag includes a tag memory to store thereto pre-determined password information and tag data, an antenna to receive a tag data transmission request signal from an outer reader, and a tag controller to request the reader to transmit the password if the tag data transmission request signal is received, and then to transmit the tag data if the password received from the reader is identical with the pre-determined password. Accordingly, it can be prevented for a third-party, who does not know the password, to check the tag data.
