Data De-Identification Services

Data de-identification services are a critical process for organizations working with sensitive data sets. Whether you’re working with medical records, financial data, or personal information, it’s important to protect the privacy of individuals and comply with data privacy regulations. In machine learning, de-identifying data is essential for building accurate and ethical models. Come work with us to keep your organization in compliance with HIPAA guidelines.

What is Data De-Identification Services?

Data de-identification services are removing or altering specific identifying information from a data set to ensure that the resulting data set cannot be linked back to a specific individual. This can include a person’s name, address, social security number, or biometric identifiers.

Why is Data De-Identification Important?

It is important for many reasons, especially in the context of training machine learning algorithms.

  • Privacy. In today’s digital age, personal information is incredibly valuable, and individuals must have control over how their information is used. Organizations can help protect sensitive information from misuse or abuse by de-identifying data.
  • Security. With so much personal information, de-identifying data will help your organization minimize the risks and consequences to the privacy of individuals from potential data breaches.
  • Legal and regulatory requirements. Data de-identification is a statutory requirement in several data privacy laws, including HIPAA and GDPR. Organizations must de-identify their data or otherwise face fines and legal action.

What PHI Data Elements Should Be De-identified?

PHI Data De-identification, also known as PHI Data Anonymization, is the process of removing or obscuring any information in a medical record that can be used to identify an individual. This includes any data created, used, or disclosed during the provision of medical services, such as diagnosis or treatment. Protected Health Information (PHI) refers to any data that can contact, locate, or identify an individual. 

Some examples of HIPAA identifiers or data elements that might be used to identify an individual and which must be de-identified include:

  • Medical images, records, health plan beneficiary, certificate, social security, and account numbers.
  • Any date directly linked to a person, such as date of birth, discharge date, date of death, and administration.
  • Any payment associated with providing healthcare services in the past, present, or future.
  • An individual’s past, current, or future health condition.

How is Data De-Identification Performed?

De-identification depends on the specific data elements that need to be removed or altered. The process often involves removing or obscuring any unique identifying number or characteristic that could link the data to a specific individual, including social security numbers, biometric identifiers, or street addresses. When conducting data de-identification for your machine learning project, we follow these steps:

Data-Collection

Data Collection

Our data collection services start by collecting the data needed for the project. Depending on the project, the data collected may include various elements, such as personal information, medical records, or financial data.

Data-Elements

Identify the Data Elements

Data annotation and data lebeling identify specific PII and PHI data elements that could be used to identify an individual, including names, social security numbers, dates of birth, or biometric identifiers.

Identifying-Information

Remove Identifying Information

The identified data elements are removed from the data set. Depending on the dataset’s needs, we approach the process using different techniques, including masking or encryption.

Add Noise

Add Noise

The step is not mandatory but can help improve the security of the data. We may add noise, including adding random values or non-individual specific data to the dataset making it more difficult to link PHI and PII data back to specific individuals.

Verify Data Quality

Verify Data Quality

The data de-identification process should not compromise the technical usability of the dataset. Our team of experts will run tests to verify the quality of your datasets to ensure they can still be used for training the ML models.

Re-Evaluate the Data Set

Re-Evaluate the Data Set

We will re-evaluate the datasets by looking at the data from various angles, including assessing their suitability based on the project’s requirements.

Types of data De-Identification

As a reputable data de-identification service providing removal or masking of all potential identifiers from your datasets, we will use one of the three main methods to identify your data.

    HIPAA safer harbor

    It involves removing specific identifying information from a data set, including names, addresses, social security numbers, and other unique identifying characteristics. This helps organizations comply with HIPAA regulations and protect sensitive patient data. The approach can be helpful to covered entities that need to de-identify protected health information, allowing the data to be used for research and other purposes.

    Elapsed day approach

    The method involves shifting or masking dates in a data set to reduce the risk of identifying a specific individual. For instance, the date of birth or admission date may be shifted by a certain number of days or months, helping to protect sensitive medical data while maintaining the overall structure of the data set. However, it is important to ensure that the shift does not affect the integrity or accuracy of the data.

    SANT method

    The Systematic Analytic Network Tool (SANT) method uses advanced statistical techniques to identify and remove any unique identifiers in a data set. SANT involves a rigorous analysis of the data set to identify potential unique identifying information and then applying statistical techniques to remove or modify the information as needed. This method requires significant expertise and resources but can provide a highly effective way to de-identify sensitive data sets.
