Encryption-based anti-counterfeiting traceability data processing method, device and system and medium

The invention provides an encryption-based anti-counterfeiting traceability data processing method, device and system and a medium, and the method comprises the steps: obtaining an identification UIDof an NFC tag, and obtaining a password corresponding to the UID from a server; encrypting original data based on the password, writing the encrypted data into the NFC tag, and setting verification information; and enabling a mobile terminal to read the data information of the NFC tag, access the server to obtain the password corresponding to the UID, verify the mobile terminal, and read the encrypted data in the NFC tag if a verification result is that the password corresponding to the UID passes the verification. According to the scheme, the encrypted data is bound with the NFC tag to ensuredata storage security of the NFC tag. The reading and displaying of the encrypted data are not limited by Android mobile phones or iPhone phones and other smart phones, so that any mobile phone supporting NFC can read the NFC
