Frequently Asked Questions

Certificate verification is the process of confirming the authenticity and validity of educational certificates, professional certifications, and other credentials using our blockchain-powered verification system.

Our system uses advanced blockchain technology to create tamper-proof records of certificates. When a certificate is uploaded, we generate a unique digital fingerprint that can be verified at any time to confirm its authenticity.

Yes, we use industry-standard encryption and blockchain technology to ensure your data is secure and tamper-proof. Your certificates are stored securely and can only be accessed by authorized parties.

Over 180 Berne Convention countries — including USA, EU, UK, Canada, China, Australia, and more

We offer a single, flexible plan — $99 for the first 500 MB (1-year validity), which includes unlimited certificate uploads, advanced verification features, and priority support. After one year, additional storage is available at $59 per 500 MB.

Yes, there's a minimum charge of $104 per certificate, regardless of file size.

If you exceed your 500 MB storage limit, you can seamlessly purchase additional storage at $59 per extra 500 MB. We’ll notify you in advance when you’re nearing your limit, so you can expand your storage without losing access or interrupting your verification services.

Yes, you can upgrade or downgrade your plan at any time. Changes will be reflected in your next billing cycle.

Pay-per-upload charges are non-refundable once processing is complete.

Verification is typically instant. Once uploaded, your certificate is immediately processed and a verification certificate is generated.

Yes, if you have the certificate ID or verification link, you can verify any certificate that has been uploaded to our platform.

We store a cryptographic hash of your certificate, upload timestamp, and basic metadata. The actual certificate content is encrypted and securely stored.

Yes, you can delete certificates from your account. However, once deleted, the verification link will no longer be valid.

Our verification provides strong evidence of document authenticity and creation date, which can be valuable in legal proceedings. However, legal binding depends on jurisdiction and specific circumstances.

Yes, we are fully GDPR compliant. You have the right to access, modify, or delete your personal data at any time.

We retain verification data for as long as your account is active. After account closure, data is retained for 7 years for legal compliance purposes.

Yes, as with any digital records, our verification data can be subject to legal discovery processes in accordance with applicable laws.

No, anyone can verify certificates using a verification link or certificate ID. However, uploading certificates requires an account.

Use the 'Forgot Password' link on the login page. We'll send you a secure reset link via email.

Currently, each account is for individual use. We're developing team and enterprise features for multiple users.

We provide email support for all users, with priority support for subscription customers. Our typical response time is within 24 hours.

Yes, we offer API access for enterprise customers who need to integrate our verification services into their existing systems.

Our platform works on all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for the best experience.

Currently, we offer a responsive web application that works well on mobile devices. A dedicated mobile app is in development.

We perform scheduled maintenance during low-traffic hours and aim for 99.9% uptime. Any planned downtime is announced in advance.

We offer REST API endpoints for integration. Contact our support team for documentation and integration assistance.

AI-based verification allows users to upload files (image, PDF, audio, or video) and automatically check if similar content already exists in the system.

Proofit converts uploaded files into AI embeddings (vector representations) and compares them against stored certificate data using advanced similarity search.

Match Percentage indicates how much of your uploaded file (pages, frames, or segments) matched a certificate in the database.

Similarity measures how closely the matched content resembles your uploaded file based on AI vector comparison.

AI similarity compares patterns and structure. Sometimes files with similar layout, formatting, or background elements may produce high similarity scores.

Not necessarily. It means all analyzed sections found matches, but similarity score determines how close the content actually is.

Proofit supports images, PDFs, audio files, videos, and certain compressed formats (ZIP) containing supported file types.

Yes, Proofit can process compressed (ZIP) files and analyze all supported content inside them.

Yes, the system automatically extracts features and performs AI comparison without manual intervention.

If no match meets the similarity threshold, the system will return zero matching certificates.

Uploaded files are processed securely. Storage policies depend on system configuration and retention settings.

Yes. Proofit can detect partial matches such as specific pages in a PDF or specific frames in a video.

Accuracy depends on content type and quality. The system uses advanced vector search to maximize detection reliability.

Similarity threshold defines the minimum confidence score required for a match to be considered valid.

Yes, administrators can configure threshold settings depending on verification sensitivity requirements.

Yes. The system is built to scale and can handle millions of stored certificates efficiently.

Videos are broken into frames, each frame is analyzed, and matching statistics are calculated based on frame-level matches.

PDFs are processed page by page. Each page is converted into embeddings and matched individually.

Audio files are converted into spectrogram representations and compared using AI embeddings.

Yes. Even if small edits are made, AI may still detect structural or visual similarity.

Higher-quality images may produce better embeddings, improving matching accuracy.

Average Similarity shows the average AI confidence score across all matched sections.

This means multiple sections matched, but the strength of resemblance is moderate rather than exact.

Yes. The system is designed to detect duplicate or near-duplicate certificates efficiently.

Yes. All comparisons are done using secure backend processing with no public exposure of file content.

Yes. AI-based similarity detection helps identify duplicate, manipulated, or reused certificate content.

The verification engine uses AI embeddings and vector database search for high-speed similarity comparison.

Yes. The architecture allows additional file formats and AI models to be integrated.
