Pillar 2: Forensic Custody
Once evidence is inside your vault, it must be protected by more than just a password. It needs a Cryptographic Shield.
Immutable Sealing
Traditional cloud storage (like Google Drive or Dropbox) allows anyone with "Edit" permissions to accidentally or intentionally modify a file. In a legal context, this is a nightmare.
SatyamevHash enforces Immutable Sealing:
1. The SHA-256 Anchor
Every file is assigned a unique SHA-256 hash. Think of this as a digital DNA strand. If even one pixel in a video is changed, the hash changes completely.
2. Blockchain Verification
We anchor your hash to the Polygon Blockchain.
- This provides a public, third-party timestamp.
- It proves that the file existed in its current state at that exact time.
- It is decentralised—even SatyamevHash cannot alter a blockchain record once it is written.
3. Zero-Knowledge Encryption
Your files are encrypted using AES-256 at the firm level.
- Your firm has a dedicated Master Key.
- SatyamevHash administrators cannot "peek" into your files.
- Your data stays in AWS Mumbai, ensuring full Indian Data Residency compliance.
Why this matters in Court
When you present evidence, you aren't just saying "here is a file." You are saying:
"Here is a file, here is its unique hash, and here is a public blockchain ledger verifying that this hash was sealed on February 12th at 10:14 AM."
This is the gold standard of digital custody.
