Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile electronic devices become increasingly diverse and capable, it becomes difficult for security administrators to quickly identify their capabilities, particularly in restricted access areas, leading to potential unauthorized access.
Innovation Solution
A system and method involving an administrator computing device and a guest computing device that utilize cryptographic codes and verification processes to securely output and verify device capabilities, using input and output mechanisms like cameras and displays to ensure authenticity and authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual inspection and manual verification methods are used to identify device capabilities, then security administrators can verify device capabilities, but the process becomes time-consuming and inefficient as device diversity increases
Solution Approach 1:
The patent replaces manual visual inspection and physical verification methods with automated optical code scanning. Security administrators use mobile devices to scan capability codes displayed on suspect devices, automatically retrieving capability information without manual inspection. This substitutes mechanical/manual verification processes with automated optical-electronic systems, dramatically reducing verification time while maintaining accuracy.
Solution Approach 2:
The patent creates machine-readable code representations (visual copies) of device capability information that can be rapidly scanned and verified. Instead of manually reading device specifications or asking users about capabilities, the system generates scannable codes that contain encoded capability data, allowing instant verification through optical scanning and automatic data retrieval.
2Reliability
If security administrators restrict devices from entering restricted areas due to inability to verify capabilities, then unauthorized access is prevented, but legitimate devices may be incorrectly blocked
Solution Approach 1:
The patent implements preliminary capability verification through code scanning before devices are allowed entry to restricted areas. Security administrators scan the capability codes of approaching devices, automatically verifying whether the devices possess prohibited capabilities. This preliminary verification process ensures that only authorized devices are permitted entry, preventing both unauthorized access and false restrictions on legitimate devices.
Solution Approach 2:
The system provides immediate feedback to security administrators regarding device capability verification results. When a capability code is scanned, the system automatically determines whether the device is authorized for entry and communicates this decision to the administrator, enabling rapid, accurate access decisions without manual judgment or uncertainty.
3Measurement precision
If comprehensive device capability information is collected and verified, then accurate security decisions can be made, but the verification process becomes more complex
Solution Approach 1:
The patent segments device capability verification into distinct modular components: capability code generation on the device, optical scanning by the administrator's device, automatic data retrieval from a database, and automated authorization decision-making. Each component handles a specific aspect of verification, reducing overall system complexity while maintaining comprehensive capability identification through structured division of the verification process.

AI summary
A system, devices and methods for verifying an administrator computing device to a guest computing device, verifying the guest device to the administrator device and outputting a list of the guest device capabilities for the administrator device such that the guest device is capable of verifying the administrator device, for example to ensure it does not divulge its capabilities to imposters, and the administrator device is capable of identifying whether the list of device capabilities is authentic. Verification can be achieved through cryptographic hashes of private certificates, digital signatures or expected output from verified modules. The list of device capabilities may be restricted based on the authorization granted to the administrator computer and may be altered or watermarked for verification. A failure to verify the administrator device may restrict execution of instructions on the guest device to prevent unauthorized access to the guest device's capabilities.
