Anti Tampering Method for Privacy Data of Multi sensor Spatial Situation Information
Abstract：The operating environment of multiple sensors is complex, and the external threat level of spatial situation information is high. The anti-tamper mechanism has low triggering times, poor sensitivity, and long response time. A research method for privacy data anti-tamper of multi-sensor spatial situation information is proposed. Based on the security requirements of privacy data, determine the key sharing strategy and set the scope of privacy data encryption query. Based on the results of multi-sensor spatial situational awareness and privacy data query, a dynamic anti-tamper mechanism is developed to achieve the anti-tamper function design of multi-sensor spatial situational information privacy data. The experimental results show that this method can respond quickly in different node environments, with a minimum response time of 1.8 seconds for third-party tamper prevention mechanisms, and low triggering times for unit blocks. This confirms that this method has good privacy data tamper prevention performance.
