Overview
Base64 Signature AI is a breakthrough solution within the Base64 Document AI platform, designed to detect, extract, and verify signatures with high accuracy across a wide variety of documents and formats. By combining advanced machine learning, proprietary computer vision, and generative AI, Signature AI automates signature comparison workflows across various industries, including finance, insurance, legal, and logistics.
Key Capabilities
- Multi-format support: Built as a core feature of Base64 Document AI, Signature AI natively supports dozens of input formats, including PDF, TIFF, JPEG, PNG, DOCX, and scanned image files.
- Progressive learning: Signature AI continually improves its accuracy and coverage through ongoing exposure to real-world documents processed by Base64 customers, with their consent.
- Generative AI for noise reduction: The system uses generative models to clean and standardize noisy or degraded backgrounds, enhancing signature isolation and improving downstream matching accuracy.
- Signature detection: All signatures are automatically located on each page using proprietary deep learning and computer vision models. For each signature, the system returns:
- Page number
- Bounding box coordinates
- Confidence score
- Cropped signature’s binary
- Signature matching: The system performs pairwise comparisons between “reference” document signatures and those in a “query” document. Each signature includes everything in Signature Detection, plus:
- Matched signatures
- Match percentage score
- Customizable parameters: The AI allows real-time fine-tuning based on several parameters.
- Maximum number of signatures
- Signature detection threshold
- Signature match threshold
- Simple integration: Signature AI is available via a single REST API endpoint, making it easy to integrate into:
- Workflow automation platforms (e.g., RPA tools)
- Document management systems
- Enterprise applications
Use Cases
- Contract compliance: Verify that all required parties signed the correct version of a document.
- Fraud prevention: Detect tampered or substituted pages by validating signature locations and appearances.
- Legal document workflows: Automate signature checks in large-scale litigation or regulatory compliance operations.
- Financial onboarding: Match signatures on application forms with ID documents.
Why Base64 Signature AI?
Base64 Signature AI offers unmatched flexibility and reliability thanks to:
- The extensive Document AI expertise is built into the broader Base64 platform
- No-code compatibility for easy integration with existing systems
- Continuous learning without customer data ever leaving the platform
- Scalable architecture suitable for processing millions of documents
