It is of high external threat to privacy information for multiple sensors to operate in complex environments.In order to effectively achieve multi-sensor privacy data and prevent tampering,this paper proposes a method for preventing the tampering of multi-sensor privacy data under situational awareness technology.The security requirements of privacy data are combined to deter-mine the key sharing strategy and set the range of the privacy data encryption query.Based on the situational awareness results of multi-sensor privacy information environments and privacy data query results,a dynamic anti-tamper mechanism is developed to a-chieve the anti tampering of multi-sensor privacy data.Experimental results show that this method has the characteristic of fast re-sponse in different node environments,with a minimum response time of 1.8 s for third-party tamper prevention mechanisms,and low triggering times for unit blocks.It is verified that this method has a good privacy data tamper prevention performance.
