Imaging Device Secure Access via Broadcast ID and Session Token
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face cumbersome registration processes and security vulnerabilities when accessing imaging devices in various facilities, as they need to manually select devices and save login details, making them prone to unauthorized access.
Innovation Solution
Implementing a central server that manages user authentication, allowing users to access imaging devices through a secure one-time session without saving login details on the device, using broadcast IDs and session tokens for secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually register with each imaging device and save login details, then they can access the device, but the process becomes cumbersome and security vulnerabilities increase
Solution Approach 1:
A central server is introduced as an intermediary between users and imaging devices. The server manages authentication by issuing temporary tokens that allow users to access devices without storing credentials locally. This mediator handles the security-sensitive operations centrally, eliminating the need for users to save login details on each device while streamlining the access process.
Solution Approach 2:
The system uses temporary, single-use authentication tokens instead of permanent login credentials. These tokens have limited validity periods and are discarded after use or expiration, preventing long-term security risks associated with stored credentials. Each token is essentially a disposable key that provides temporary access without compromising long-term security.
2Reliability
If users save login details with each imaging device, then they can authenticate, but they become vulnerable to security breaches
Solution Approach 1:
Authentication credentials are extracted from the imaging devices and centralized on a secure server. The devices no longer store sensitive login details; instead, they verify temporary tokens issued by the server. This extraction removes the security vulnerability from the devices while maintaining authentication capability through the centralized credential management system.
Solution Approach 2:
The authentication mechanism changes from static, long-term credentials to dynamic, temporary tokens with time-limited validity. This parameter change transforms the authentication approach from storing permanent passwords to using ephemeral access keys, fundamentally reducing the window of opportunity for security breaches while maintaining reliable authentication.
3Adaptability or versatility
If users connect to imaging devices in multiple facilities, then they can use the devices, but they must manually select and register with each device
Solution Approach 1:
The central server provides universal authentication that works across multiple imaging devices in different facilities. A single user account on the server can access any registered device anywhere in the network, eliminating the need for separate registrations at each location. This universal access mechanism enables users to work across multiple facilities without repeating the registration process.
Solution Approach 2:
Authentication credentials and device permissions are pre-configured on the central server before users need to access devices. When users arrive at any facility, the system has already prepared their access rights, allowing immediate authentication without on-site registration. This preliminary setup of credentials eliminates the time-consuming registration step at each new location.

AI summary
An example imaging device includes a communication engine to transmit a broadcast message including a broadcast ID corresponding to the imaging device. The communication engine further is to receive a session token from a central server in response to a request for accessing the imaging device received from a user device in receipt of the broadcast ID. The session token is to connect the imaging device to a user session corresponding to a user of the user device. The imaging device further comprises a user authorization engine to obtain preliminary user details from the central server using the session token. The preliminary user details include a login ID and a user-selected authentication mode. The user authorization engine is to set-up a user login session using the preliminary user details for receiving user authentication approval from the central server to allow the user to access the imaging device.
