Abstract: A method for protecting data in a Wireless Body Area Network (WBAN) system is performed as follows. A current status of a data in a WBAN system is monitored and obtained. A potential risk to the data in the current status is assessed based on nodes in the WBAN system and a path between the nodes. A risk level of the WBAN system is quantified by calculating a risk degree of the potential risk under attack methods. First protection schemes are selected from a second protection schemes based on the risk level of the WBAN system. The first protection schemes are evaluated based on Analytic Hierarchy Process (AHP), by taking the attack methods, an utility and an efficiency of the first protection schemes as evaluation indicators to select a third protection scheme from the first protection schemes. The data is processed according to the third protection scheme.
