Method, system and apparatus for NFC security
A method, system and apparatus for providing security to RFID and NFC systems. In some exemplary embodiments, a smart poster may be utilized to provide appropriate or desired communications with an RFID or NFC-enabled device. Such exemplary embodiments may utilize an authorized NFC tag to communicate with an NFC-enabled device, and upon activation of the authorized NFC tag, may trigger activation or appearance of one or more related items, such as visual cues. Additionally, aspects of NFC security systems which can include regions of security, states of activity and actions performed when security violations are detected.
1. A method for detecting of an unauthorized NFC tag, the method comprising:
using a radio frequency identification (RFID) interrogation system with a near field communication (NFC) controller, the interrogation system provided in a frame having an antenna and a display having a surface;
executing a security scan;
checking for the unauthorized NFC tag;
detecting the unauthorized NFC tag that does not have information about the surface of the display, wherein the unauthorized NFC tag does not provide its intended communication capabilities; and
performing at least one action.
2. The method of claim 1 , wherein the at least one action includes disabling the unauthorized NFC tag.
3. The method of claim 1 , wherein the at least one action includes at least one of the group consisting of reprogramming the memory contents of the unauthorized NFC tag and jamming the communication channel of the unauthorized tag.
4. The method of claim 1 , wherein the at least one action includes at least one of the group consisting of alerting authorized personnel and disabling the display.
5. The method of claim 1 , further comprising interrogating the authorized NFC tag and checking if the memory contents and identification code remain uncorrupted.
6. The method of claim 5 , further including performing at least one action on any authorized corrupted NFC tag.
7. The method of claim 6 , wherein the at least one action on any authorized corrupted NFC tag includes at least one of disabling the at least one unauthorized NFC tag, reprogramming the memory contents of the unauthorized NFC tag and jamming the communication channel of the unauthorized tag.
8. The method of claim 1 , further comprising:
detecting at least one authorized tag programmed with information about a surface of the display and that has authorized RFID device properties to function on the surface.
