Authoritative Display for Critical Systems Using Partial Image Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Critical systems face challenges in ensuring the validity of images displayed on graphical interfaces, as incorrect yet valid images can be undetectable, leading to potential catastrophic consequences, and current designs often require expensive, highly reliable components to minimize this risk.
Innovation Solution
A system that generates multiple partial images from subsets of the original image data, combines them, and presents them in a single graphical display, allowing operators to authenticate and validate the image through metadata and digital signatures, ensuring that incorrect images appear as invalid, thus reducing the risk of single-point failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dual displays are used to present critical information, then the reliability of the system is improved, but the device complexity and ease of operation deteriorate due to requiring constant scanning of two screens
Solution Approach 1:
The image data is divided into multiple partial images, each rendered independently through separate command streams. This segmentation allows validation of individual portions without requiring complete duplication of the entire display system, reducing complexity while maintaining reliability.
Solution Approach 2:
The patent creates a copy of the image data and renders it as multiple partial images through different command streams. This copying mechanism enables validation without requiring expensive dual display hardware, as the validation can be performed on the same physical display through comparative rendering.
2Reliability
If highly reliable hardware and software components are used, then the fault tolerance of the critical system is improved, but the cost of the system increases
Solution Approach 1:
The patent performs preliminary validation by rendering partial images through multiple independent command streams before final display. Digital signatures and metadata are verified in advance, allowing detection of corruption or tampering before the image is presented to the user, thereby achieving fault tolerance through software validation rather than expensive hardware redundancy.
Solution Approach 2:
The system implements feedback mechanisms where the rendered partial images are compared against expected values and digital signatures. This feedback loop validates the integrity of image data and rendering processes, enabling reliable operation with standard components by continuously monitoring and verifying system state.
3Difficulty of detecting and measuring
If multiple independent command streams are used to render partial images, then the detectability of incorrect images is improved, but the processing time and device complexity increase
Solution Approach 1:
The patent renders only partial images (portions of the complete image) through multiple command streams rather than rendering entire images separately. This partial action approach enables validation of critical portions without the time penalty of complete redundant rendering, balancing detectability with processing efficiency.
Data Source
AI summary
A system and method of rendering an authoritative image on a graphical display that is part of a critical system wherein image data is received from a source and the image data is stored in a storage module. The plurality of partial images are then generated from a subset of the image data, the partial images can include an indicator. The plurality of images are then combined to form the image, and the image is presented in a single graphical display. The image can then be evaluated by an operator for validity and correctness.
