Build an AI Image Moderation System with AWS Rekognition
Blog post from Stream
Integrating image uploads into live streams or chats enhances user engagement but also poses challenges related to inappropriate content. To address this, image moderation using AI tools like AWS Rekognition becomes essential. AWS Rekognition, Amazon's machine-learning computer vision service, provides content moderation capabilities by detecting inappropriate content across several categories such as explicit nudity, violence, and gambling, using a confidence-based approach. Developers can fine-tune moderation thresholds based on community guidelines by leveraging confidence scores. The application process involves uploading user images to an AWS S3 bucket and using the AWS Rekognition API to analyze and moderate the content before displaying it. The setup requires configuring both the Stream account and AWS Rekognition, along with setting up an S3 bucket with appropriate permissions for moderation. A React-based chat application can incorporate this moderation pipeline, ensuring that images are checked for inappropriate content before being displayed, improving platform safety and compliance. Additionally, features like expanded moderation categories, a human moderation queue, user trust systems, and analytics can be implemented to create a comprehensive moderation platform. Stream's chat API offers built-in moderation features using AWS Rekognition, simplifying the integration of these functionalities.
