AI Architecture Behind Image Verification for Employee Portal Apps
Employee portals like PegDesk use advanced AI to ensure every uploaded image or captured photo meets company standards securely and instantly.
The system runs entirely on-device using Google ML Kit, which analyzes images in real time to detect potentially inappropriate or sensitive content before it’s stored or shared.
1. How the Detection Process Works
The image verification module follows a simple yet effective pipeline:
Image Input → Label Detection → Contextual Analysis → Result Classification.
Every image is labeled using ML Kit’s on-device model, which recognizes over 400 object and scene categories (e.g., “person,” “office,” “beach,” “bedroom”). These detected labels are then analyzed for context, allowing the system to flag images that may be unsuitable for workplace environments.
2. Confidence-Based Classification
Each label generated by ML Kit includes a confidence score between 0 and 1. The system applies tiered thresholds to determine whether an image might be inappropriate:
- High Confidence (≥0.7): Likely inappropriate context detected.
- Medium Confidence (≥0.6): Requires secondary check.
- Low Confidence (<0.5): Considered safe.
This ensures the app balances accuracy with minimal false positives, maintaining both security and user trust.
3. Contextual & Category-Based Filtering
Rather than identifying explicit content directly, ML Kit focuses on contextual labeling. It detects scenes such as “nightclub,” “swimwear,” or “bedroom,” which may suggest non-workplace-appropriate environments.
These contextual insights are then categorized into three groups: High Confidence Inappropriate, Potentially Inappropriate, and Adult Indicators, giving admins clear visibility and control.
4. Privacy-First Design
All analysis happens on the employee’s device, not on external servers. This ensures total privacy, zero data transmission, and full compliance with security standards. The app never uploads images to the cloud for analysis, making it ideal for organizations that prioritize confidentiality and data protection.
5. Built for Speed and Reliability
Powered by Kotlin Coroutines and asynchronous image processing, the AI runs smoothly in the background without slowing down the app. Images are resized before processing to optimize performance, and results are cached for repeat verifications. This combination of real-time speed and offline reliability ensures a seamless user experience even in low-connectivity environments.
Limitations and Best Practices of ML Kit Image Verification
While Google ML Kit brings powerful on-device AI capabilities, it’s important to understand its boundaries. The system works best for contextual analysis rather than direct content detection.
Knowing what it can and cannot do ensures realistic expectations and more accurate implementation.
What ML Kit Cannot Detect
ML Kit is not designed to directly identify explicit or harmful imagery. It cannot detect nudity, violence, drug use, or adult content with precision. Instead, it focuses on recognizing contextual elements around an image, such as settings or objects, that may hint at inappropriate environments.
For comprehensive moderation, it should be paired with specialized detection or manual review systems.
What ML Kit Can Detect
The tool excels at recognizing real-world objects, environments, and human activities. It can label scenes like “office,” “beach,” or “nightclub” and detect elements such as “person,” “drink,” or “swimwear.”
These contextual insights help the app classify workplace-appropriate images while maintaining complete privacy. Detection accuracy for contextual analysis typically ranges between 70-80%, which is ideal for real-time pre-screening.
Detection Accuracy & Real-World Behavior
ML Kit’s contextual labeling can occasionally misclassify images. A neutral photo may be flagged if taken in an ambiguous setting, or inappropriate content might go unnoticed if the background appears harmless.
These false positives and negatives are expected in contextual AI. The key is to use ML Kit as an initial filter, not as a final moderation tool, and combine it with human validation when needed.
Implementation Best Practices
For the best results, follow these engineering and operational guidelines:
- Set Realistic Expectations: Treat ML Kit as contextual AI, not explicit detection.
- Use as a Filter: Pair it with secondary moderation or human review.
- Show Transparency: Display detected labels to users.
- Allow User Override: Let users challenge or confirm flagged results.
- Handle Errors Gracefully: Provide fallback messages and safe defaults.
Performance Optimization Tips
Optimize performance by resizing large images before analysis and running detection tasks asynchronously using Kotlin Coroutines. Cache frequently analyzed results to improve speed and reduce redundant processing. Implement clear error handling and structured logging to catch and resolve issues quickly during production.
Privacy and Data Control
ML Kit’s strongest advantage lies in its privacy-first architecture. All analysis happens on the device, meaning no data or images are ever transmitted externally. Results can be stored locally if required, giving full control to the organization and the user. This design ensures compliance with privacy laws while protecting sensitive employee data.
