Abstract

The invention discloses a hidden camera sensing and positioning method and system, and the accuracy of camera sensing is greatly improved by extracting the length, period and bandwidth of a camera flow packet and the stability of each flow, constructing a four-dimensional vector, and carrying out training classification through machine learning. In addition, the invention provides a human body mobility network camera positioning method oriented to encrypted traffic, and the direction of the camera is positioned by capturing the change of the traffic of the camera when the human body moves, drawing a real-time oscillogram of the change of the bit rate and analyzing the trend of the change of the bit rate. According to the invention, the positioning accuracy and the software practicability are greatly improved, and a convenient and rapid camera positioning function is realized.

Description

technical field [0001] The invention belongs to the field of computer network technology and application security technology, and in particular relates to a hidden camera perception and positioning method and system. Background technique [0002] Wi-Fi is a wireless local area network technology based on the IEEE 802.11 standard, which is used for network connection of devices with wireless network functions. It is the most widely used wireless network transmission technology today. WIFI does not require wiring, and the wired signal can be converted into a wireless signal through the wireless access point (AP) of the wireless router to build a wireless local area network. Typically, cameras process video / audio streams and then upload them to a cloud server via a wireless local area network (WLAN), allowing remote monitoring in real time or later. If the characteristics of the traffic are analyzed, the specific traffic characteristics emitted by the camera can be identified....
