基于深度情景群智感知的面向移动互联网的主动防御技术研究

Mobile security problem is becoming more and more serious. In order to effectively perceive the mobile context for active defense, Crowd Sensing provide large data and low cost labels. However, traditional learning methods failed to adapt to its dynamic and mixed data environment. To solve above problem, we study the Key theories and methods of Deep Crowd-sensing based Mobile Context-Aware Active DefenseTechnique, which including Multi-source multimodal sensor data association and fusion based on Deep Mutual transfer learning; Constrained online incremental learning based scene discovery method in Mobile Crowd-Sensing; Dynamic adaptive context aware access control model based on automatic classification combined with user feedback. This project aims to reveal the "cross source and cross modal Deep Mutual transfer" optimal rules between the context aware model in the crowd sensing, realization of accurately context classification and deep fusion of the mixed context data; and to find an effective deep incremental scene discover method and context security grading method, and final realization of mobile security context aware dynamic access control policy. It is expected to be a breakthrough in the context aware active security technology in the mobile environment, will also has theoretical significance of considerable support to Crowd-sensing problems of common concern.
