RESEARCH AND IMPLEMENTATION OF AN INTELLIGENT FIREWALL SYSTEM BASED ON IMAGE CONTENT FILTERING

Considering the deficiency of current network security system’s image processing ability, an intelligent firewall system is developed in this paper, which is based on image content filtering. The system can detect the image information of the network truly and quickly, so it improves the reliability and security of the runtime network system. An image content retrieval algorithm based on layout feature extraction and multi\|agent technology is brought forward. For the first time it treats the image retrieval problem as a distributed solving problem, and makes the agent technology as the supporting technology. Therefore, it solves the low efficiency of the current multi\|dimensional indexing algorithm acting on the large\|scale image library, and improves the system’s retrieval speed under the condition of keeping the high recognizing rate.
