Defend knowledge in transit
Information encryption is used to make sure that knowledge communications between your utility and Amazon Transcribe stay confidential. Use sturdy encryption algorithms to guard knowledge throughout transmission.
Amazon Transcribe can function in one among two modes:
- Streaming Transcription Permits dwell media streaming transcription
- Batch transcription job Permits using asynchronous operations to transcribe audio recordsdata.
In streaming transcription mode, the shopper utility opens a bidirectional streaming connection by way of HTTP/2 or WebSockets. The app streams audio to Amazon Transcribe, and the service responds immediately with the textual content stream. Each HTTP/2 and WebSocket stream connections are established over Transport Layer Safety (TLS), a extensively accepted encryption protocol. TLS makes use of AWS credentials to authenticate and encrypt knowledge in transit. We suggest utilizing TLS 1.2 or larger.
In batch transcription mode, you first must put the audio recordsdata into an Amazon Easy Storage Service (Amazon S3) bucket. Then, create a batch transcription job in Amazon Transcribe that references the S3 URI of the archive. Amazon Transcribe and Amazon S3 in batch mode each use HTTP/1.1 over TLS to guard knowledge in transit.
All requests to Amazon Transcribe over HTTP and WebSockets should be authenticated utilizing AWS Signature Model 4. It is usually beneficial to make use of signature model 4 to authenticate HTTP requests to Amazon S3, though the older signature model 2 may also be used for authentication in some AWS Areas. Purposes should have legitimate credentials to signal API requests to AWS companies.
Defend knowledge at relaxation
Amazon Transcribe in batch mode makes use of S3 buckets to retailer enter audio recordsdata and output transcription recordsdata. The client makes use of an S3 bucket to retailer enter audio recordsdata and it’s extremely beneficial to allow encryption on this bucket. Amazon Transcribe helps the next S3 encryption strategies:
Each strategies encrypt buyer knowledge when it’s written to disk and decrypt it once you entry it utilizing one of many strongest block ciphers obtainable: 256-bit Superior Encryption Customary (AES-256) GCM . When utilizing SSE-S3, encryption keys are managed and rotated periodically by the Amazon S3 service. To enhance safety and compliance, SSE-KMS gives prospects with management over encryption keys by AWS Key Administration Service (AWS KMS). AWS KMS gives extra entry management since you should have permission to make use of the suitable KMS keys to encrypt and decrypt objects in an S3 bucket configured with SSE-KMS. As well as, SSE-KMS gives prospects with an audit path that information who used your KMS keys and when.
Output transcripts might be saved in the identical or a distinct customer-owned S3 bucket. On this case, the identical SSE-S3 and SSE-KMS encryption choices apply. An alternative choice for Amazon Transcribe output in batch mode is to make use of a service-managed S3 bucket. The output knowledge is then positioned right into a safe S3 bucket managed by the Amazon Transcribe service, and you’re given a short lived URI that you need to use to obtain the script.
Amazon Transcribe makes use of encrypted Amazon Elastic Block Retailer (Amazon EBS) volumes to briefly retailer buyer knowledge throughout media processing. The client knowledge of each full circumstances and failed circumstances shall be cleared.
Finest Apply 2 – Talk over a devoted community path
Many purchasers depend on in-transit encryption to speak securely with Amazon Transcribe over the Web. Nevertheless, for some functions, encryption of information in transit might not be ample to fulfill safety necessities. In some circumstances, knowledge could not traverse public networks such because the Web. Moreover, it could be essential to deploy the appliance in a non-public atmosphere that’s not linked to the Web. To satisfy these necessities, use interface VPC endpoints powered by AWS PrivateLink.
The next structure diagram demonstrates the use case of deploying an utility on Amazon EC2. The EC2 occasion working the appliance doesn’t have entry to the Web, however communicates with Amazon Transcribe and Amazon S3 by the interface VPC endpoint.
In some circumstances, functions that talk with Amazon Transcribe could also be deployed in a neighborhood knowledge heart. There could also be extra safety or compliance necessities that require knowledge exchanged with Amazon Transcribe to not be transmitted over public networks such because the Web. On this case, a devoted connection by AWS Direct Join can be utilized. The next diagram exhibits an structure that permits native functions to speak with Amazon Transcribe with out being linked to the Web.

This function helps prospects obtain Fee Card Business (PCI) compliance by modifying PII similar to credit score or debit card numbers, expiration dates and three-digit card verification numbers (CVV). Transcripts containing redacted info could have the PII changed with placeholders in sq. brackets to point the kind of redacted PII. Streaming Transcription helps the extra function of merely figuring out and tagging PII with out modifying it. The kinds of PII compiled by Amazon Transcribe differ between bulk and streaming transcriptions. For extra particulars, see Enhancing PII in a Batch Job and Enhancing or Figuring out PII in a Stay Stream.
