Title:
TIME-BASED ENCRYPTED NFC CELL PHONE TERMINAL ANTI-COUNTERFEIT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2016/145705
Kind Code:
A1
Abstract:
Disclosed are a time-based encrypted NFC cell phone terminal anti-counterfeit system and method. Firstly, a system time is sent to an NFC anti-counterfeit label, and after receiving the system time, the NFC anti-counterfeit label obtains check data hash by unidirectionally encrypting data; then the NFC anti-counterfeit label sends a product ID, other information about a product and check data hash to a cell phone client via a wireless signal; and sends the product ID and the check data hash to a background data management system; after the reception, the background database management system uses the same encryption algorithm to obtain check data hash 0 and compares the obtained result hash 0 with the value of hash; and after verification, sends a result of the verification to the cell phone client. The system comprises an NFC anti-counterfeit label and a background data management system. The present invention has the advantages of a high cost for and a great difficulty in fabrication, a small size, a high efficiency of verification, and is thus applicable to a variety of products and is convenient to use.
