# Redaction Methodologies

Teleskope offers granular controls for redacting sensitive information, enabling the safe and efficient anonymization of datasets for consumption.

### Replace your sensitive data with:

**Entity Type**: Replaces identified sensitive data with its corresponding entity label.

**Entity Type Incremented**: Replaces sensitive data with its corresponding entity, appended by an incrementing ID with a given payload. If an entity is repeated, it retains the same replacement value.

**Empty Strings**: Removes sensitive data and replaces it with an empty string.

**Masking Characters**: Replaces sensitive data with configured characters. In Masking, Teleskope also allows users to replace portions of sensitive data, using specified characters, while ignoring other specified characters.

**Deterministic Encryption (with Referential Integrity)**: Encrypts data using AES-SIV with a cryptographic key, and replaces the original value with a base64-encoded representation of the encrypted value. This enables the ability to revert encrypted data to its original state. This generates identical tokens for each instance of an identical input value.

**Synthetic Data**: Replaces sensitive data with mocked data of a corresponding length. This method optionally allows for referential integrity, enabling the ability to revert this data to its original values.

#### The following contain examples of each redaction method:

| Redaction Method         | Before                    | After                                                                               |
| ------------------------ | ------------------------- | ----------------------------------------------------------------------------------- |
| Entity Type              | "Hi, my name is John Doe" | "Hi, my name is FIRST\_NAME LAST\_NAME."                                            |
| Entity Type Incremented  | "Hi, my name is John Doe" | "Hi, my name is FIRST\_NAME\_1 LAST\_NAME\_1."                                      |
| Empty Strings            | "Hi, my name is John Doe" | "Hi, my name is ."                                                                  |
| Masking Characters       | "Hi, my name is John Doe" | "Hi, my name is \*\*\*\* \*\*\*."                                                   |
| Deterministic Encryption | "Hi, my name is John Doe" | “Hi, my name is FIRST\_NAME(13):AT1OQpkW7qhzx LAST\_NAME(20):A123k;j123B+e94xSYnK.” |
| Synthetic Data           | "Hi, my name is John Doe" | “Hi, my name is Finn Qou”                                                           |

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.teleskope.ai/specifications/redaction-methodologies.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
