Breath Analyzer Video Metadata Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breath analysis devices lack authentication of the donor and administrator, and the results are prone to human error and loss, making it difficult to present reliable evidence in legal proceedings.
Innovation Solution
Integration of video cameras and a proximity tag system with the breath analyzer to authenticate the procedure and preserve results, which are then stored as metadata with the video recordings, allowing for secure and accurate presentation of the analysis results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If breath analysis results are displayed only on the device screen, then the device complexity is low, but the reliability of evidence preservation is poor due to human error and potential loss of records
Solution Approach 1:
The patent merges the breath analyzer with video camera functionality and metadata embedding capabilities into a single integrated device. The breathalyzer captures breath samples, displays results on its screen, simultaneously records video of the procedure, and embeds the breath analysis results as metadata within the video file structure. This consolidation eliminates the need for separate recording devices and manual documentation processes, thereby improving evidence preservation reliability while managing system complexity through integration.
Solution Approach 2:
The patent creates a digital copy of the breath analysis results by embedding them as metadata within the video file structure. Rather than relying on physical notes or separate storage media that could be lost or damaged, the breath analysis data is copied into the video metadata, ensuring permanent association with the visual record and eliminating concerns about record loss or human transcription errors.
2Loss of information
If manual recording of breath analysis results is used, then the device complexity is low, but the loss of information increases due to potential errors in reading, recalling, and recording
Solution Approach 1:
The breath analyzer performs self-service by automatically capturing its own display results, converting them to metadata, and embedding them within the video file structure. The device autonomously extracts the breath analysis data from its screen, formats it appropriately, and integrates it with the video recording without requiring administrator intervention for data transcription or transfer, thereby eliminating human error in information recording.
Solution Approach 2:
The patent replaces the manual mechanical process of reading, writing, and storing breath analysis results with an automated digital system. Instead of the administrator manually transcribing data from the device screen to paper or digital notes, the system automatically captures the display output, converts it to metadata format, and embeds it within the video file structure, eliminating human transcription errors entirely.
3Reliability
If authentication features are added to verify donor and administrator identity, then the reliability of the analysis is improved, but the ease of operation decreases due to additional procedures
Solution Approach 1:
The patent merges the authentication system with the video recording and metadata embedding functions. The device captures images or video of the administrator and donor, extracts identifying features or data from these visual records, and embeds this authentication information as metadata within the same video file structure that already contains the breath analysis results. This integration allows multiple authentication and documentation functions to be performed simultaneously without requiring separate procedures or steps.
Data Source
AI summary
A breath analyzer, a system, and a computer program for administering a breath analysis to a donor and recording a breath analysis result. Embodiments of the invention authenticate that the breath analysis was performed correctly, preserves the breath analysis results by communicating with other devices, and presents the breath analysis results by superimposing them on recorded video data. The breath analyzer includes a breath receptor for receiving a breath sample from the donor, an analyzing element for determining a breath analysis result, a communications element for sending information indicative of the breath analysis result to a recording device manager, and a housing for securing the components in a handheld device. The system comprises the breath analyzer, a recording device manager for synchronizing the recordings, and at least one ancillary camera for recording the breath analysis.
