Embodiment
[0043] A bottle cap anti-counterfeiting method based on Internet of Things technology, such as figure 1 shown, including the following steps:
[0044] (1) Verification code generation: One or more verification codes are actively or passively generated on the bottle cap according to the existing algorithm, and displayed in the form of plain code or encrypted password; for the verification code, it is a dynamic sequence of numbers, or no barcode , two-dimensional code, and alphanumeric combination, when encrypted, it is the encrypted password;
[0045] The random verification code can be generated by means of digital signature, and it can be calculated using national secret algorithm. There is a security chip in each bottle cap module, which stores the key corresponding to a product serial number (commodity unique code). At the same time, the security chip performs high-precision timing (under the condition of self-contained battery), or records the number of user operations (...
