P55 Watermark is a real-time source and data validation system built on top of P55 Nexus. It is designed to ensure trust and integrity in data pipelines, where packets or messages are wrapped inside a secure envelope containing both the data and a verifiable P55.
Unlike header-based injection approaches, the final architecture uses an envelope model where the validator gateway explicitly inspects and verifies each message.
- P55 Watermark applies the P55 Nexus engine to real-time data pipelines. Built on Envoy Gateway, it enables:
- Real-time validation of data source and content integrity
- Deterministic P55s computed using payload metadata
- Stateless verification by downstream systems via envelope inspection
- Validating telemetry in critical infrastructure
- Ensuring video/audio feeds originate from trusted systems
- Detecting tampering in JSON, XML, or protobuf payloads
- Tagging and verifying command streams in military and industrial IoT
P55 Watermark functions as a native plugin on both the generator and validator Envoy gateways:
-
Generator creates a P55 using metadata like source, destination, and the data
-
The output is packed into an envelope:
{
"payload": { ... },
"p55": "Key#messageID#f03c48a911..."
}
- Validator unpacks the envelope, verifies the P55
- If valid: message is forwarded to destination
- If invalid: message is sent to quarantine or dropped
