Synthetic Data: The Future of Data Privacy and Security

 In today's data-driven world, companies and organisations across industries constantly collect, analyse, and utilise data to inform their decisions and strategies. However, using real-world data can present various challenges, particularly in data privacy and security. This is where synthetic data comes in as an innovative solution that balances data privacy and data utility.

In this blog post, we'll explore the importance of synthetic data and why it should be considered a best practice in various industries, focusing on personal identifiable data and GDPR.

What is Synthetic Data?

Synthetic data refers to artificially generated data that mimics the statistical properties of real-world data. It can be created using various techniques such as generative adversarial networks (GANs), agent-based simulations (ABM), variational autoencoders (VAEs), and other machine learning algorithms. The resulting synthetic data can be used in place of real-world data in various applications, such as training and validating machine learning models.

Why Synthetic Data?

The use of synthetic data can address various pain points in the industry, particularly in terms of data privacy and security. Real-world data may contain sensitive information that can put individuals at risk if it falls into the wrong hands. Synthetic data can be used to preserve data privacy by creating data with similar statistical properties to real data but without any identifying information. This can also address issues related to data confidentiality, where sensitive data needs to be shared or used for research purposes.

Pain Points with Personal Identifiable Data

Personal identifiable data, or PII, refers to any information used to identify a specific individual. PII includes names, addresses, email addresses, phone numbers, social security numbers, and other sensitive information. Law often requires companies and organisations to protect PII, and failure to do so can result in legal and financial penalties.

One of the significant regulations around PII is the General Data Protection Regulation (GDPR), which applies to any company or organisation that handles the personal data of European Union citizens. The GDPR mandates that companies and organisations obtain consent from individuals to collect and use their personal data and protect that data from unauthorised access and misuse.

How Synthetic Data Can Help

The use of synthetic data can help companies and organisations comply with GDPR and other regulations around PII. Synthetic data can replace real PII data in applications such as machine learning models without compromising data privacy. This can ensure that PII data is kept confidential and is not exposed to potential breaches or unauthorised access.

Synthetic data can also help address other pain points related to PII, such as data diversity. Real-world PII data may not fully capture the diversity of possible scenarios, which can limit the performance of machine learning models. Synthetic data can introduce new and diverse scenarios, improving the model's robustness.

Use Cases for Synthetic Data

There are various use cases for synthetic data across industries, such as healthcare, finance, and transportation. For example, synthetic data can be used in the financial services industry to create stress testing scenarios and train machine learning models for fraud detection. In healthcare, synthetic data can be used for drug discovery and clinical trial simulations, while in transportation, it can be used for modelling traffic patterns and optimising logistics.

Conclusion

In summary, the use of synthetic data is a powerful solution for the challenges faced by various industries in terms of data privacy, security, and utility. It offers a practical way to maximise the utility of data while ensuring compliance with regulations such as GDPR without compromising the privacy of individuals or revealing confidential information.

As a data enthusiast and a believer in the power of technology, I strongly encourage decision-makers and regulatory bodies across industries to adopt synthetic data as a best practice for data privacy and security. By doing so, companies and organisations can unlock the full potential of machine learning while also protecting the privacy of individuals and preserving the confidentiality of sensitive data.

In conclusion, synthetic data is the future of data privacy and security. With the power of synthetic data, you can achieve compliance and innovation and take your data-driven initiatives to the next level.
