SEEM Protocol

Simple Encrypted Event Messages

Privacy-first messaging without the complexity

The Problem

Traditional webhooks and event delivery have issues:

• Requires public endpoints - Opens security vulnerabilities
• Data sent in plaintext - Intermediaries can see everything
• Complex infrastructure - Need servers, networking, firewall rules
• Privacy concerns - GDPR compliance challenges

There has to be a better way.

The Solution: SEEM

End-to-end encrypted messages with zero-knowledge intermediaries

Key idea: Only the recipient can decrypt messages, even if they pass through a broker

How It Works (Simple Version)

Think: Encrypted voicemail

1. Someone leaves you a message (encrypted)
2. Message stored somewhere you can retrieve it
3. Only you can listen to it (decrypt)
4. Automatically deletes after 1 hour

No one else can hear it. Not even the phone company.

Two Ways to Use SEEM

Option 1: Direct Delivery

You have a server? Messages go straight to you.

Option 2: Broker Mode

No server? Use a desktop app that checks for messages.

Both are end-to-end encrypted.

Option 1: Direct Delivery

You have a server - messages delivered in real-time

Option 2: Broker Mode

No server needed - just install a desktop app

What Makes SEEM Special?

Privacy by Design

• Zero-knowledge brokers (can't read your data)
• Auto-deleting messages (1 hour default)
• GDPR-friendly from day one

Developer-Friendly

• One-line integration
• Automatic retry logic
• Works everywhere (browser, mobile, IoT)

Simple

• No complex networking
• No public endpoints needed
• Just works™

Use Cases

Feedback Widgets
Collect user feedback without backend infrastructure

Error Reporting
Client-side error tracking with privacy

Analytics
Privacy-first event collection

Form Submissions
Encrypted contact forms without servers

IoT Telemetry
Sensor data with zero-knowledge intermediaries

Integration Example

<script src="https://cdn.seem.dev/seem.js"></script>
<script>
  const seem = new SEEM({
    broker: 'https://broker.seem.dev',
    siteId: 'my-site',
    publicKey: '...'
  });

  seem.send({
    type: 'feedback',
    data: { message: 'Great product!', rating: 5 }
  });
</script>

That's it. Really.

Security Highlights

Strong encryption

• RSA-2048 for key exchange
• AES-256 for data encryption

Multiple verification layers

• Outer hash (before decryption)
• Inner checksum (after decryption)
• Timestamp validation (replay protection)

Zero-knowledge architecture

• Broker cannot decrypt messages
• Only recipient has private key

Privacy Features

Minimal data retention

• Messages auto-delete after TTL (default: 1 hour)
• No indefinite storage
• No tracking, no analytics on broker

GDPR compliance built-in

• Privacy by design
• Data minimization
• Right to erasure (auto-deletion)
• Clear data flows

What's Next?

Currently:

• Complete v1.0 specification
• Developer documentation
• Reference implementations in progress

Coming Soon:

• Desktop dashboard (Windows, macOS, Linux)
• Browser extension for easy key management
• Integration templates (Slack, email, webhooks)
• Deployment guides (Docker, cloud providers)

Why Build This?

Webhooks are complicated:

• Complex infrastructure
• Trust everyone with your data
• Expose public endpoints

SEEM is simple:

• End-to-end encryption by default
• Zero-knowledge intermediaries
• No infrastructure required
• One line of code

Privacy should be simpler than the alternative.

The Vision

Make privacy-first messaging easier than webhooks.

Enable developers to build privacy-respecting applications without:

• Sacrificing user experience
• Complex cryptography knowledge
• Any infrastructure at all

Privacy should be effortless, not expensive.

Key Takeaways

1. SEEM makes privacy effortless - simpler than webhooks
2. Zero-knowledge brokers can't read your data
3. No infrastructure needed - just a desktop app
4. One line of code to integrate
5. Privacy by default - GDPR compliance built-in
