Secure Team Collaboration & Session Handoff
The Circle of Trust, Digitally Enforced
The Problem
Collaboration usually breaks privacy. If one person redacts a document and another person needs to read the AI's output, they must manually coordinate the 'key' to the placeholders. Cloud-based 'Shared Workspaces' solve this by storing your data on their servers—creating a single point of failure. Teams need a decentralized way to share trust.
How It Works
Encrypt Session
Generate a unique 'Secure Handoff' link or .pssession file using your team passphrase.
Share Securely
Send the link via Slack, Teams, or Email. Not even the message provider can read the data.
Remote Reveal
Your colleague enters the passphrase to instantly 're-hydrate' the AI's response.
How This Feature Improved Workflows
Argon2id & XChaCha20: The New Standard for Team Privacy
PrivacyScrubber TEAMS introduces a breakthrough in decentralized data sharing. By leveraging Authenticated Encryption with Associated Data (AEAD) via the libsodium library, we provide a "Secure Handoff" mechanism that is faster and safer than traditional AES implementations.
The Handoff Architecture
- Key Derivation: Your team passphrase is processed through Argon2id (the winner of the Password Hashing Competition), making it resistant to GPU-based brute-force attacks.
- Local Encryption: Your SessionMap is encrypted into a binary buffer using XChaCha20-Poly1305.
- Stateless Transmission: This buffer is encoded into a URL hash or a .pssession file. You own the transport layer—we never touch the data.
- Local Decryption: The recipient's browser performs the inverse operation entirely in memory.
This "Zero-Server Handoff" ensures that your organization maintains absolute control over its Data Residency. Whether your team is in New York, London, or Tokyo, the PII never enters a third-party cloud, satisfying even the most stringent GDPR and HIPAA requirements.
Feature Reliability & Audit
This enterprise feature is powered by our Local-First Sanitization Engine. Unlike legacy cloud DLP tools, PrivacyScrubber processes your Secure Team Collaboration & Session Handoff logic 100% within your browser's V8 sandbox. This architectural decision ensures that even the most complex detection patterns never expose raw data to an external API.

Frequently Asked Questions
How does the 'Magic Link' work without a database?
The link contains the entire encrypted session map as a Base64-encoded string in the URL hash. Since the hash is never sent to the server (it stays in the browser), the data travels with you across devices securely.
What happens if a link is intercepted?
The data is useless without your private team passphrase. We use Argon2id to derive a nearly-impossible-to-brute-force key, ensuring that even if a link is leaked, your PII remains safe.
