Introduction

In the context of data transformation and de-identification, generating a unique and deterministic ID is crucial for maintaining data integrity and ensuring that the de-identified data remains consistent with the original data. The generate_id transformation, introduced in issue #64, provides three options: incremental, hash, and uuid. While these options offer pre-determined output types, there is a need for a more flexible approach that allows for generating a new de-identified ID of the same data type as the non-de-identified data. In this article, we will explore the possibilities of providing options for generate_id to output a deterministic value of a specific data type.

Current Options: `incremental`, `hash`, and `uuid`

The generate_id transformation currently offers three options:

Incremental

The incremental option generates a new ID by incrementing the previous ID. This approach is useful when working with numerical data, as it ensures that the generated ID is of the same data type as the original data.

Hash

The hash option generates a new ID by hashing a value. This approach is useful when working with string data, as it ensures that the generated ID is of the same data type as the original data.

UUID

The uuid option generates a new ID using a universally unique identifier (UUID). This approach is useful when working with string data, as it ensures that the generated ID is of the same data type as the original data.

Desired Features: Deterministic ID Generation

While the current options provide a good starting point, there are several features that would make the generate_id transformation more useful:

Specify output type: The ability to specify the output type of the generated ID would be beneficial, especially when working with data of different types.
Deterministic generation: The ability to generate a new ID in a deterministic fashion would ensure that the generated ID is consistent and predictable.
Format-preserving encryption: The use of format-preserving encryption (FPE) would allow for generating a new ID that is of the same format as the original data, while still being encrypted.

Exploring Options for Deterministic ID Generation

To achieve the desired features, several options can be explored:

Format-Preserving Encryption (FPE)

FPE is a type of encryption that preserves the format of the original data. This approach would allow for generating a new ID that is of the same format as the original data, while still being encrypted.

Hash-based ID Generation

Hash-based ID generation involves using a hash function to generate a new ID. This approach would allow for generating a new ID in a deterministic fashion, while still being able to specify the output type.

Incremental ID Generation

Incremental ID generation involves incrementing the previous ID to generate a new ID. This approach would allow for generating a new ID in a deterministic fashion, while still being able to specify the output type.

UUID-based ID Generation

UUID-based ID generation involves using a UUID to generate a new ID. This approach would allow for generating a new ID in a deterministic fashion, while still being able to specify the output type.

Implementation Considerations

When implementing the desired features, several considerations should be taken into account:

Performance: The implementation should be efficient and performant, especially when working with large datasets.
Security: The implementation should ensure that the generated ID is secure and cannot be easily guessed or reversed.
Flexibility: The implementation should be flexible and allow for specifying the output type and deterministic generation.

Conclusion

In conclusion, the generate_id transformation provides a good starting point for generating unique and deterministic IDs. However, there are several features that would make the transformation more useful, including specifying the output type and deterministic generation. By exploring options such as format-preserving encryption, hash-based ID generation, incremental ID generation, and UUID-based ID generation, it is possible to achieve the desired features. When implementing the desired features, performance, security, and flexibility should be taken into account.

Future Work

Future work should focus on implementing the desired features and exploring new options for deterministic ID generation. This may involve:

Implementing FPE: Implementing FPE to allow for generating a new ID that is of the same format as the original data, while still being encrypted.
Exploring new hash functions: Exploring new hash functions that provide better performance and security.
Developing incremental ID generation: Developing incremental ID generation to allow for generating a new ID in a deterministic fashion, while still being able to specify the output type.

Introduction

In our previous article, we explored the possibilities of providing options for generate_id to output a deterministic value of a specific data type.
