Introduction

MB-Forensic project is a forensic watermarking automation process running on Azure cloud to apply watermarking on Azure Media Services (AMS) Assets.

MB-Forensic is composed by a orchestrate (Logic App), Actions (Azure Functions) and watermarker container on Kubernetes cluster. The process are expose by REST APIs making easy integration with existing MAM or workflows managers.

Getting Started

Installation, build and Test process

MB-Forensic installation process is divided on 2 main sub systems

a. Azure Container Service. Details steps are describe on k8s\readme.md

b. Logic Apps and Functions. Details steps are describe on ForensicWaterMark\readme.md file.

API references

MB-Forensic expose 2 simple RESP API to apply watermarking on AMS assets.

Start watermark Job

Start a new watermark job using UnifiedProcess Logic App.

Request URL

a. https: //{Logic App Endpoint}.logic.azure.com:443/workflows/{Logic App ID}}/triggers/manual/paths/invoke?api-version=2016-06-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig={Logic App KEY}

Request Headers

a. Content-Type: application/json

Request Body

POST CALL to CallBack URL specifying AssetId of original Assset and EmbebedCodes list. Each code on the list will produce a new Asset copy on AMS.

a. AssetId: AMS Asset ID string . b. EmbebedCodes: Text list of HEX codes.

{
  "AssetId": "nb:cid:UUID:79d815cc-5cbe-4a99-add9-c74eeeeb596a",
