Patent ID: 8209546

Claim:
A data-securing method for use in a program tool used for modifying a SOC of an electric product, comprising steps of: a) performing a first processing step with a first input data by a first processing device of the program tool to generate a first output data; b) transferring the first output data by a flow control center to perform an encryption step of the first output data by an encryption/decryption module of the program tool to generate an encrypted first intermediate output data, the encrypted first intermediate output data being accessible by a program-tool user; c) transferring the encrypted first intermediate output data by the flow control center to perform a decryption step of the encrypted first intermediate output data by the encryption/decryption module of the program tool to recover the first output data, the recovered first output data being inaccessible by the program-tool user; and d) performing a second processing step with the recovered first output data by a second processing device of the program tool to generate a second output data.
