Sacura — Tamper‑Evident Packaging Reinvented
We don’t just promise trust. We prove it — physically and digitally.
Illustration: vacuum‑sealed particle pouch with cryptographic QR binding.
About Sacura
We’re not just building tamper‑evident packaging — we’re building trust, layer by layer, byte by byte.
Physical + Digital
Entropy‑rich physics secured with modern cryptography.
Low‑Cost, Scalable
Works with standard materials and mobile devices.
Investor‑Ready
Transparent roadmap, auditability options, and IP moat.
Why TEP matters
Most existing solutions are either too easy to spoof, rely on human judgment, or add prohibitive cost. Sacura creates an objective, measured check on integrity.
- • Objective signal (match score), not subjective inspection
- • Visual proof that degrades on opening (irreversible disruption)
- • Commodity hardware for verification (smartphone camera)
How we solve it
Each unit forms a unique pattern at seal time; that image is fingerprinted and bound to the product. Later captures are compared against this ground truth.
- • High‑entropy physical randomness
- • Cryptographic commitment to identity
- • Robust image matching pipeline
How the Technology Works
Our four-step process combines physical entropy with cryptographic security to create an unforgeable link between a product and its digital record.
1. Pattern Generation
Particles sealed under vacuum form a unique, non‑repeatable fingerprint.
2. Fingerprint Capture
A high‑res image is taken at seal time and linked to a QR code.
3. Immutable Storage
The fingerprint is stored securely, with optional blockchain anchoring.
4. End‑User Verification
A smartphone app scans and compares patterns to verify integrity.
Interactive Verification Demo
Adjust the tamper level with the slider to see how our system instantly detects a mismatch in the unique physical fingerprint.
Baseline (at seal time)
Note: This demo uses a simplified matcher. The production system uses a robust computer vision pipeline.
Real‑World Use Cases
From pharmaceuticals to luxury goods, Sacura provides a universal layer of trust for physical assets.
Crypto Hardware Wallets
Prevent firmware tampering before first use.
Pharmaceuticals
Safeguard drugs from dilution or theft in transit.
Legal Documents
Seal sensitive paperwork with verifiable integrity.
Luxury Goods
Stop product swaps and counterfeiting.
Consumer Electronics
Prevent hardware injection or malware installs.
Defense & Government
Secure equipment transport with proof of integrity.
Mission
Develop tamper‑evident packaging that is visibly secure, cryptographically verifiable, low‑cost, and easy to inspect without specialized tools.
Vision
A world where tampering is instantly evident, forgery is futile, and verification is universal — from crypto wallets to life-saving vaccines.
The Sacura Difference
We don’t just seal — we generate evidence.
We don’t rely on human inspection — we automate detection.
We don’t make packaging disposable — we aim for reusable security.
We don’t sell stickers — we build verifiable systems.
