AI-Powered UK Passport Photo Validation Workflow
detail.loadingPreview
Automate the tedious process of validating passport photos against strict UK government guidelines using AI. This n8n workflow leverages a powerful AI vision model to analyze images, ensuring compliance and providing structured feedback instantly. Streamline photo submission and approval with intelligent automation.
About This Workflow
This robust n8n workflow empowers you to automatically validate passport photos according to the detailed criteria set by the UK government. It begins by securely importing images from sources like Google Drive, then preprocesses them for optimal AI analysis. A sophisticated AI vision model meticulously scrutinizes each photo against comprehensive rules, including facial expression, background, lighting, and dimensions. Finally, the workflow parses the AI's assessment into a clean, structured JSON output, indicating validity, providing a description, and listing specific reasons for any rejections. This ensures rapid, consistent, and compliant photo verification, significantly reducing manual effort and potential errors.
Key Features
- AI-Driven Compliance: Automatically verifies passport photos against official UK government guidelines using advanced AI vision.
- Automated Image Handling: Seamlessly imports photos from Google Drive (and easily adaptable for other sources) and resizes them for AI processing.
- Detailed Photo Analysis: AI assesses criteria like clarity, focus, background, facial expression, glare, and adherence to specific rules for glasses or head coverings.
- Structured Output: Generates clear, actionable JSON output including
is_validstatus,photo_description, and a list ofreasonsfor non-compliance. - Scalable & Flexible: Easily processes multiple photos in batches and can be integrated with various LLM providers and storage solutions.
How To Use
- Configure Photo Source: Update the "Photo URLs" Set node with your desired image links, or replace the Google Drive nodes with your preferred storage or a webhook to receive images.
- Google Drive Credentials (if using): Ensure your "Download Photos" node has valid Google Drive OAuth2 API credentials configured to access the specified image URLs.
- AI Vision Model: The "Passport Photo Validator" (Chain LLM) node is pre-configured with UK government guidelines. Ensure your LLM provider (e.g., OpenAI) is properly connected and supports vision capabilities for optimal results.
- Review Output Schema: The "Structured Output Parser" node defines the exact JSON structure for the AI's response. Modify the
inputSchemaif you need to adjust the output fields or their descriptions. - Test and Integrate: Run the workflow to test with sample photos. The structured output can then be easily integrated into databases, notification systems, or other downstream processes.
