Amazon Textract is a machine learning service that makes it easy to extract printed text, handwriting, and data from virtually any document. Today, we are pleased to announce that Amazon Textract supports encryption of its asynchronous API output stored in your Amazon S3 buckets using your own AWS Key Management Service (KMS) Customer Master Keys (CMKs). With this feature, you have the flexibility to manage which encryption keys are used to protect your data and text extracted by Amazon Textract. For more information on how to accomplish this, please read our newest blog post.
