Introduction

In this article, we will explore the usage of Gretel's Transforms API. We will learn how to identify sensitive personal information within a dataset and then modify it using automatic transformations. Using this API, you can ensure the privacy and security of personal data while still handling it effectively.

Using Gretel's Transforms API

To begin, we need to upload a dataset to Gretel's platform. Once uploaded, we can choose the Transforms API to run our desired transformations. This API provides deterministic automatic transforms that can be applied to various attributes within the dataset.

What is a Transform?

A transform refers to a specific modification or operation that can be applied to data. In our case, we will focus on identifying and modifying sensitive personal information such as person names, credit card numbers, and phone numbers.

Running Transforms

With the dataset and the Transforms API selected, we can run the transformations. Here, we employ natural language processing (NLP) techniques to identify named entities within the data. NLP algorithms search for examples of names, addresses, and other entities, ensuring the privacy of sensitive information.

Protecting Sensitive Personal Information

Datasets often contain personal information like names, phone numbers, and email addresses. To safeguard this sensitive data, we need to replace it with fake or artificial counterparts. By doing so, we prevent machine learning algorithms from learning the actual personal data and thereby maintain privacy.

Replacing PII with Fake Data

Instead of redacting or replacing sensitive information with generic placeholders, Gretel replaces personally identifiable information (PII) with artificial or fake data. For example, names like Patty Young or Carol and Ralph are transformed into Charles May, Gregory Hall, and Randy Martinez, respectively. This approach ensures the data remains realistic while protecting individual privacy.

Configuring Transform Options

When running the transforms, Gretel provides default configurations. However, you have the flexibility to adjust these options according to your requirements. Whether you choose to run the worker in the cloud or deploy it to your own environment, Gretel offers the necessary customization options.

Running Transforms in the Cloud

Gretel provides the option to run the transformation worker in the cloud. This allows for seamless processing of large datasets and efficient utilization of computing resources. Additionally, running the worker in the cloud ensures scalability and ease of access.

Viewing Transform Results

Once the transformation process is complete, you can view the results. The Gretel platform provides an overview of the different entity types detected in the dataset, such as email addresses, locations, person names, and phone numbers. You can also see the total count of each entity type and the specific fields in which they are found.

Comparing Original and Transformed Data

To evaluate the effectiveness of the transformations, you can compare the original dataset with the transformed version. By doing so, you can observe the replacement of sensitive information with fake data. This comparison is particularly useful when training synthetic models, such as chatbots or natural language understanding models, where privacy is essential.
