Israel Releases 2014 Birth Data While Protecting Privacy

In February 2024, Israel's Ministry of Health made public a Dataset containing information about live births that occurred in 2014. This dataset holds a lot of value for various fields, including research and policy development. However, the data was handled carefully to protect the Privacy of the mothers and newborns involved. A special method was used to ensure that personal information could not be traced back to individuals.

#Purpose of the Dataset Release

The dataset was designed to be useful for scientific research and to help inform decisions in public health. By making the information accessible, researchers, policymakers, and other Stakeholders can use it to gain insights into demographic trends, health conditions, and economic factors related to birth data.

#Privacy Measures

To protect the privacy of the individuals in the dataset, several measures were taken. The release of this sensitive data followed strict regulations to avoid any potential harm to the privacy of the mothers and newborns. The methodology for the release was developed in collaboration with various stakeholders, ensuring that their needs and concerns were taken into account.

#Data Processing

The dataset consists of records from the National Registry of Live Births in Israel. It includes 167,000 entries, but only specific fields of information were selected for public release. The fields included data that would be valuable to users while maintaining a level of privacy for the individuals involved.

The dataset was processed to ensure that it was suitable for public use. This included a combination of data transformation and a selection of algorithms to maintain privacy. Techniques such as "differential privacy" were employed, which helps to control how much individual records can influence the output when data analysis is done.

#Methodology Overview

The authors developed a comprehensive plan that involved several steps for releasing the dataset. The methodology concentrated on combining various techniques to secure the privacy of the data while ensuring that the dataset remained useful for analysis. The process included generating a separate synthetic dataset that reflects the original data but does not include any personal details.

#Stakeholder Engagement

It was essential to involve various stakeholders throughout the process. These stakeholders included representatives from health research platforms, epidemiology teams, and medical researchers. Their feedback shaped the direction of the project and helped ensure that the final product met the needs of various users.

#Data Quality Assurance

Ensuring high-quality data in the release was a priority. Different criteria were established to assess the accuracy and reliability of the information. These criteria were used to verify that the released dataset closely matched the original in terms of statistical properties, providing confidence in the data for users.

#Acceptance Criteria

Multiple acceptance criteria were set to ensure the quality and privacy of the dataset. These included criteria for assessing errors in statistical queries and comparing results against the original dataset. By evaluating these criteria, it ensured that the released data was accurate and maintained the desired privacy standards.

#Synthetic Data Generation

Synthetic data was created as part of the release process. This means that the final dataset does not contain real individual records but instead is generated based on patterns in the original data. The synthetic data provides a way to analyze trends and patterns without revealing any personal information about the mothers or newborns.

#Data Evaluation

The released dataset was subjected to thorough evaluation using the established acceptance criteria. Each criterion was carefully assessed to ensure the synthetic data's quality and compliance with privacy standards. This evaluation process was essential to guarantee that the dataset was indeed useful for research and decision-making.

#Privacy Loss Budget

The team set a privacy loss budget that dictates how much individual data can impact the overall dataset. This budget is crucial in maintaining a balance between data utility and privacy protection. The effective management of this budget was a key aspect of the project's success.

#Trust and Transparency

It was vital to foster trust in the data release. The process was designed to ensure that the dataset met the expectations set by stakeholders. By documenting every step of the methodology and openly communicating about the data, the team aimed to establish trust and transparency in the use of sensitive information.

#Future Releases

The team plans to continue refining the methodology and exploring additional releases of data in the future. Feedback from stakeholders will guide subsequent efforts, allowing for improvements and enhancements in the process.

#Conclusion

The release of the 2014 live birth data from Israel's National Registry marks a significant step in making government data more accessible while ensuring individuals' privacy. By utilizing advanced techniques and engaging stakeholders throughout the process, the dataset has been crafted to serve valuable insights for research and policy development while protecting the privacy of those involved.
