Abstract

A system and method for updating a compensation value of a measurement machine provides a host computer to generate an authorization code document according to an ID input by a user and encrypts the authorization code document. A client computer decrypts the authorization code document, and obtains an authorization code, the input ID, and a valid date of the authorization code. If the input ID is the same as an ID of the measurement machine, and the authorization code has not expired, the compensation of the measurement machine can be updated by the client computer using the authorization code.
