A Dense Radiation Imaging System Based on Random Thickness Liquid Mask

Abstract

The invention discloses an encrypted radiation imaging system based on a random thickness liquid mask, which includes an X-ray source, an object to be detected, a liquid metal mask, a thickness control array inside the mask, and an X-ray detector. The thickness control array randomly adjusts the thickness of the liquid mask, realizes random attenuation of the X-rays penetrating the mask, and then encrypts the sensitive information carried in the X-ray imaging, effectively protecting the sensitive information of the items to be inspected, and realizing Encryption measures of physical shielding are used for the energy and position information of the emitted particles, and the proposed security inspection technology encrypts the information carried by the emitted X-rays from the physical field, avoiding the risk of private information being leaked, and will not expose any information about the items to be inspected. For privacy information, the template comparison method is used to facilitate the confirmation of whether the items to be inspected contain contraband, and the security inspection is realized on the basis of protecting the sensitive information of the inspected items.

Description

technical field [0001] The invention relates to the technical field of information and security, in particular to an encrypted radiation imaging system based on a random-thickness liquid mask. Background technique [0002] For some important places in the country, such as military secret places, the protection of security issues is extremely important. Dangerous items are strictly prohibited in these places. The list of prohibited items is listed by the supervisor, and most of the current security inspection equipment is based on X-ray imaging. principle, to identify and judge; [0003] However, to inspect the equipment through the imaging principle of X-rays, due to the strong perspective of X-rays, privacy will be violated during the inspection process, and this phenomenon will not be accepted in some special cases, so the current inspection equipment cannot To check the safety of items without infringing on privacy, therefore, it is necessary to provide a security inspec...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an encrypted radiation imaging system based on a random-thickness liquid mask, which can effectively solve the problem in the background technology that because X-rays have strong perspective, privacy will be violated during the inspection process, and this phenomenon occurs in some It will not be accepted under special circumstances, so the current inspection equipment cannot verify the safety of items without violating privacy
