The present disclosure provides a method for anti-tampering apparatus servicing data implemented by a calculation device connected to a target device, the method comprising: identifying a contract identification code and obtaining a contract package file and a contract authentication code from at least one remote device; obtaining a microservice file corresponding to the target device from the remote device when a device embedded code of the calculation device is matching the contract authentication code; performing the microservice file to enable the target device according to the contract package file and generate an execution report; publishing the execution report to the remote device to obtain an acceptance certification code; and combining and hashing the device embedded code, the contract authentication code and the acceptance certification code to generate a hash value, and sending the hash value to a blockchain. The present disclosure further provides a system for anti-tampering apparatus servicing data.
