A security device method of massage

The present invention discloses a security method and structure for a massage apparatus, wherein the first generation product serial number of the massaging device in a host computer; and then the sequence number is set according to the communication protocol is encapsulated packet, and transmitted to the control circuit of the massaging device by the massage device located external communication interface; re-extracted information of the sequence number of the data packet, and writes the serial number of the control circuit using an analog EEPROM ROM mode designated region; last ROM hardware automatically using the data in the designated area is encrypted; read using a terminal, access the designated area of ​​the control circuit, wherein the extracting and decrypting information, to obtain the output sequence number the output terminal of the apparatus. This security scheme no additional physical components, such as stickers, symbol marks, etc., at the same time, the electronic control system is developed based on the original, full use of a ROM memory and a communication interface, so that no additional costs.
