Right to Erasure & Deletion

Introduction

The Right to Erasure, also known as the "Right to be Forgotten," is a concept grounded in data protection and privacy laws, particularly the GDPR. It allows individuals to request the deletion of their personal data when it is no longer necessary for the purposes it was collected for.

Key Concepts

• Data Subject: The individual whose personal data is being processed.
• Data Controller: The entity that determines the purposes and means of processing personal data.
• Data Processor: The entity that processes data on behalf of the controller.
• Legal Justifications for Processing: Conditions under which personal data may be processed legally.

Step-by-Step Process

The following flowchart outlines the process for handling a Right to Erasure request:

            graph TD;
                A[Receive Erasure Request] --> B{Is the request valid?};
                B -- Yes --> C[Verify Identity];
                C --> D[Assess Legal Grounds];
                D -- No Grounds --> E[Inform Data Subject];
                D -- Grounds Exist --> F[Delete Data];
                F --> G[Notify Data Subject];
                B -- No --> E;
            

Implementation in AWS

When implementing erasure in AWS, consider the following:

                import boto3

                # Initialize S3 client
                s3 = boto3.client('s3')

                # Function to delete an object from S3
                def delete_object(bucket_name, object_key):
                    response = s3.delete_object(Bucket=bucket_name, Key=object_key)
                    return response['ResponseMetadata']['HTTPStatusCode'] == 204

                # Example usage
                delete_object('my-bucket', 'data/user123.json')
                

Best Practices

• Implement a clear data retention policy.
• Regularly audit data storage for compliance.
• Use AWS tools like AWS Lambda to automate erasure processes.
• Ensure all team members are trained on data privacy laws.
• Maintain logs of all erasure requests and actions taken.
