The Data Scientist’s Challenge
If you work as a data scientist, you know the risk: models, datasets, and analysis notebooks represent IP that needs creation proof. When it comes to protecting portfolio work, the stakes are real - without independent evidence, disputes become your word against theirs.
Your Workflow with TimeProof
Timestamp the public-facing portfolio file before posting or sharing it so later public-copying disputes can point to the exact work product, not only to a compressed platform copy. Best used before posting portfolio work publicly or sharing it in pitches, applications, or review rounds. Common files in this workflow include portfolio exports, case-study PDFs, and presentation decks. Typical reviewers or counterparties include clients, hiring teams, and reviewers.
1. Train model.
2. Export weights.
3. Timestamp model + training data.
4. Document.
The timestamp step fits into that workflow without changing the tools you already use.
The timestamping step itself takes under 10 seconds. No blockchain expertise required.
Why Protecting Portfolio Work Matters
Prove original authorship of portfolio pieces published online. A blockchain timestamp protects their portfolio with creation timestamps, creating evidence that is:
- Independent — stored on the public Polygon blockchain, not controlled by TimeProof or any party
- Permanent — cannot be altered, deleted, or disputed after recording
- Verifiable — anyone can check the timestamp on Polygonscan without an account
- Cryptographic — the SHA-256 hash changes if even one byte of the file changes
How Timestamping Works
When a data scientist timestamps a file for protecting portfolio work, TimeProof uses client-side file hashing (SHA-256). That 64-character value is the unique fingerprint for the exact version you selected, and if even one byte changes, the hash changes too. That fingerprint proves the exact version you created before it is shared or disputed. Your file never leaves your device.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. The blockchain records the hash, timestamp, and transaction ID permanently, so anyone can verify the record independently on Polygonscan without relying on screenshots, local metadata, or someone else’s database.
For data scientists, ML engineers, and analytics professionals, that means prove original authorship of portfolio pieces published online without relying on editable logs or file-system dates.
What You Receive
Every TimeProof timestamp for protecting portfolio work includes:
- PDF certificate - a readable proof document you can keep with the project file, send to a client, or hand to counsel if the timeline is later challenged.
- Polygonscan link - direct public verification so a reviewer can confirm the blockchain record independently.
Verified instant timestamps also include: 3. Verified identity badge - the certificate shows the timestamp was created by a verified account, which is useful when timing and submitter identity both matter to the dispute or review.
With the Legal-Grade upgrade, you also receive the core evidence-package components documented by TimeProof: PDF, JSON, JWS identity attestation, and a ZIP bundle.
- Courtroom-Ready PDF - a presentation-ready evidence certificate when protecting portfolio work needs more than a standard project record.
- JSON Metadata - machine-readable timestamp data for technical teams, audit trails, or structured evidence review.
- Identity Attestation (JWS) - a signed proof that ties the timestamp to a verified identity and can be verified through /.well-known/jwks.json.
- Complete Evidence ZIP - one bundle containing the Courtroom-Ready PDF, JSON Metadata, Identity Attestation (JWS), and supporting proof materials such as the Merkle proof, verification guide, and checksums, so the record is ready for formal review.
Real Scenario
Imagine you are a data scientist. A creator needs proof of authorship after a portfolio piece is copied from a public gallery, pitch deck, or case-study archive. The files at issue are often portfolio exports, case-study PDFs, and presentation decks. Typical counterparties include clients, hiring teams, and reviewers.
A copied portfolio piece appears elsewhere, a potential client reuses the work without hiring you, or a reviewer disputes who published the piece first. The timestamp proves the exact portfolio file existed before the copied post or reuse appeared, even if the platform stripped metadata or compressed the public version.
With TimeProof, the dispute is resolved by independent proof instead of by screenshots, local metadata, or conflicting memories.
Related Comparisons
These comparisons help you evaluate adjacent proof methods before you settle on the workflow for this use case.
- TimeProof vs Adobe Content Credentials: Compare provenance labels with independent file timing when public portfolio copying becomes a dispute.
- TimeProof vs Watermarking: See why visible deterrence does not replace proof of when the portfolio asset itself existed.
- TimeProof vs Copyright Registration: Compare formal registration with lightweight recurring proof for active portfolio publishing workflows.

- Prove Ownership of Design Files: Move from public-display protection into direct authorship proof on the underlying portfolio files.
- Protect Design Files Before Sharing: Protect work earlier in the process when review-round sharing happens before publication or payment.
- Pricing: Review the current credit model for recurring portfolio, showcase, and client-review workflows.
Cost for Data Scientist
TimeProof uses one unified credit balance, so data scientists, ML engineers, and analytics professionals can create routine proof early and only step up to verified features when the situation calls for it.
- Scheduled timestamps: 1 credit per file - available to everyone, with proof available within 6 hours.
- Instant timestamps: 2 credits per file - available to verified subscribers, anchored in about 2 seconds.
- Legal-Grade: Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.
One-time packs start at $15 for 100 credits. Verified monthly plans start at $19/month and include identity verification for instant timestamps and Legal-Grade.
That lets you use scheduled timestamps for everyday protecting portfolio work records and reserve verified instant or Legal-Grade proof for the files most likely to be challenged.
Most data scientists, ML engineers, and analytics professionals need routine, repeatable protection rather than an enterprise rollout. TimeProof is priced for routine use through packs and verified monthly plans, so you can build evidence as you work instead of only after a dispute starts.
Privacy
Your files related to this workflow never leaves your computer. TimeProof uses client-side file hashing (SHA-256). Only the 64-character hash string is sent for anchoring. Because SHA-256 is one-way, it is not possible to reconstruct the original file from the hash. That lets data scientists, ML engineers, and analytics professionals protect work related to protecting portfolio work without exposing the original file, unpublished draft, or client material.
