Embodiment 1

[0033] figure 1 It is a flow chart of a method for detecting stolen camera equipment based on electromagnetic leakage provided by an embodiment of the present invention. refer to figure 1 A detection method for stealing equipment based on electromagnetic leakage provided by an embodiment of the present invention may include the following steps:

[0034] Step S101, acquiring a target electromagnetic fingerprint model.

[0035] In the embodiment of the present invention, the target electromagnetic fingerprint model is an electromagnetic fingerprint model obtained after sampling the background environment electromagnetic in the area to be detected. Among them, the electromagnetic fingerprint in the target electromagnetic fingerprint model is the result obtained by removing the background electromagnetic from the preset electromagnetic fingerprint of the bootleg equipment at the factory, and the result is generally saved in the form of a relative ratio or a relative threshold. ...

Abstract

The invention, which relates to the technical field of the electronic product, provides an electromagnetic-leakage-based method and device for detecting a stealing-shooting device, comprising: firstly, obtaining a target electromagnetic fingerprint model; acquiring a target electromagnetic fingerprint at any position in the to-be-detected area by using a detection probe; calculating gain values ofthe collected target electromagnetic fingerprint and each electromagnetic fingerprint in the target electromagnetic fingerprint model to obtain at least one gain value; and finally determining whether the device corresponding to the target electromagnetic fingerprint is a stealing device based on the at least one gain value. The target electromagnetic fingerprint model can avoid the interferenceof the external environment, and improves the detection accuracy. Automatic collection of electromagnetic fingerprints can be achieved through the detection probe. Due to the fact that electromagneticleakage protection is difficult to achieve in the use scene of the stealing and shooting equipment, the discovery rate of the stealing and shooting equipment can be increased.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a detection method and device for stealing equipment based on electromagnetic leakage. Background technique [0002] With the increasing number of piracy, the black industrial chain market brought about by piracy equipment is expanding infinitely. Stealing equipment is gradually developing in the direction of general planning and batch standard production. Taking the most common pirating equipment——pinhole camera as an example, manufacturers produce standardized motherboards and standardized lens modules, and buyers can assemble and manufacture by themselves. camouflage. In this mode, there are various camouflage schemes for stealing equipment. [0003] Traditional optical detection technology is affected by the interference of camera surface material, light source and environment, which affects the accuracy. The detection rate of traditional optical detection is l...
