Utilize Amazon DynamoDB for storage, apply a rule to filter sensitive data during writes, and employ DynamoDB Streams for data sharing.

Leverage Amazon Kinesis Data Firehose to stream and store data in DynamoDB and S3, integrate AWS Lambda for data sanitization, and enable S3 as the data consumption source for applications.

Use Amazon S3 to batch and store transaction files, apply AWS Lambda for processing and sensitive data removal, then update S3 and store sanitized data in DynamoDB for application access.
