Solution Overview
Problem
Existing imaging systems face challenges in efficiently transmitting and analyzing images across different physical locations without causing delays or interruptions, particularly in security screening environments like airports, where real-time analysis of luggage contents is crucial.
Innovation Solution
A method and system for secure transmission of images from image acquisition devices to remote viewing devices using encrypted and compressed data, employing downsampling and parallel processing to minimize latency and downtime, allowing analysis at separate locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If images are transmitted in real-time across different physical locations, then analysis speed and productivity are improved, but data security and transmission reliability deteriorate due to network vulnerabilities
Solution Approach 1:
The system performs preliminary actions by encrypting images at the source device before transmission and preparing decryption keys in advance. The remote device receives pre-encrypted data that can be immediately processed upon arrival, eliminating the need for security negotiations during transmission and enabling real-time analysis while maintaining security.
Solution Approach 2:
The patent extracts the security function from the transmission process by using endpoint encryption - the source device extracts and applies encryption before transmission, and the remote device extracts and applies decryption after reception. This separates security operations from the network transmission layer, allowing fast transmission while maintaining security.
2Reliability
If high-resolution images are transmitted securely with encryption, then data security is improved, but transmission time and processing latency increase
Solution Approach 1:
The system creates a copy of the image data that is encrypted at the source device. This encrypted copy is transmitted to the remote device where it is decrypted and analyzed. The original unencrypted image remains only at the source device, eliminating the need to transmit large unencrypted files while maintaining full security and resolution.
Solution Approach 2:
The patent changes the parameter of the image data from unencrypted to encrypted form before transmission. This parameter change enables security protection without affecting the image resolution or quality, as encryption operates at the data level rather than altering the image content itself.
3Productivity
If multiple scanners are coordinated across different locations, then resource utilization and analysis capability are improved, but system complexity and coordination overhead increase
Solution Approach 1:
The system implements feedback mechanisms where the remote device sends confirmation signals back to the source device after receiving and processing images. This feedback loop enables automatic coordination between multiple scanners, allowing them to operate efficiently in parallel while maintaining synchronization through simple signal exchanges rather than complex management protocols.
Data Source
AI summary
A method for remote identification of security threats in an imaged object including transmitting an initialization signal to a first threat detection scanner over a communication network, the first threat detection scanner being located at a separate physical location, receiving a ready-to-send signal from the first threat detection scanner, the ready-to-send signal including a storage location of a scan image generated by the first threat detection scanner for security inspection, receiving the scan image from the first threat detection scanner, transmitting, after receiving the scan image from the first threat detection scanner, a second initialization signal to a second threat detection scanner at the separate physical location, generating a threat detection report based on a rendering of the scan image, and transmitting the threat detection report to the first threat detection scanner.
