CUBIG’s Synthetic Data: Overcoming Data Regulations and Solving the Data Silo Problem (12/17)

*Synthetic Data

1. General Knowledge

1.1. What is Synthetic Data?

Synthetic data refers to data that mimics the statistical properties of real data while excluding sensitive information. It is an innovative solution that helps organizations bypass strict data regulations such as GDPR in Europe and HIPAA in the United States. By leveraging synthetic data, organizations can safely share and utilize data without compromising privacy.

1.2. Traditional AI Models for Generating Synthetic Data

Traditional AI models, such as Generative Adversarial Networks (GANs), can generate synthetic data across various domains, including images, text, and tabular data. Synthetic data generated through GANs has been widely used to train AI models, simulate realistic scenarios, and improve system performance.

However, traditional AI models face significant limitations:

• Inability to reproduce real-world complexity: GANs often fail to replicate the intricate and diverse patterns of real-world data accurately.
• Bias replication: If the original data contains biases, synthetic data generated from it can inherit and amplify these biases.
• Privacy risks: To achieve high performance, traditional models sometimes overfit to the original data, creating synthetic data that is too similar to the source. This raises concerns about privacy breaches when sensitive information is unintentionally reproduced.
  

2. Real-World Examples of Security Breaches from Synthetic Data

2.1. Healthcare Data Breach in a U.S. Hospital Network

A prominent U.S. hospital network attempted to leverage synthetic data to comply with HIPAA regulations while sharing patient medical records. Using GANs, the hospital generated synthetic MRI scans to facilitate medical research and train AI diagnostic models.

However, the GAN model, designed to replicate realistic data, overfitted to the original dataset, producing synthetic images that were nearly identical to real patient scans. Upon investigation, it was discovered that sensitive patient information—such as embedded metadata (e.g., patient IDs) and distinct MRI features—remained intact.

This breach not only violated HIPAA regulations but also raised serious concerns about the use of synthetic data in healthcare without proper safeguards. The incident highlights the challenges of balancing privacy and realism in AI-driven synthetic data generation.

2.2. Customer Image Leakage in Retail

A major U.S. retailer used customer behavior data to generate synthetic images for AI-driven applications, such as object recognition and shopper behavior analysis. The goal was to create realistic data without infringing on customer privacy.

However, the GAN-generated images mimicked the original dataset too closely, producing synthetic images that visibly resembled actual customers. Facial features, body shapes, and clothing details were replicated with striking similarity.

In addition to privacy risks, the synthetic data inadvertently revealed customers’ identities and their purchasing habits, leading to a breach of consumer trust. This case underscores the need for stricter measures to ensure synthetic data does not reproduce identifiable information from real-world datasets.

2.3. Financial Consultation Data Leak

A U.S.-based financial institution sought to generate synthetic versions of customer consultation records to train AI models for fraud detection and credit scoring. The synthetic data included tabular and textual records generated using a traditional GAN model.

While the intent was to anonymize the data for internal and external usage, the model’s lack of privacy safeguards led to significant issues. During an audit, it was found that critical details—such as credit scores, loan repayment histories, and customer profiles—were reproduced with minimal changes from the original dataset.

In certain instances, individual records could be partially re-identified, causing compliance risks with financial privacy regulations. The institution faced significant backlash, highlighting the risks of using synthetic data without robust privacy protection measures.

2.4. Facial Recognition Privacy Violation

A research team developing facial recognition technology turned to synthetic face data to train AI models. Their intention was to replace real-world photographs with synthetic alternatives, ensuring privacy compliance.

However, the GAN model tasked with generating realistic facial features overfitted to the source dataset. This resulted in synthetic face images that bore uncanny resemblances to real individuals, with some faces matching those in publicly available datasets.

The revelation raised ethical and privacy concerns, as synthetic face data risked inadvertently exposing the identities of individuals in the original dataset. This case sparked debates about the ethical use of synthetic data in biometric AI applications and exposed the weaknesses of traditional generation techniques.

2.5. License Plate Exposure in Autonomous Driving Data

In the autonomous driving industry, synthetic datasets are essential for training AI systems to recognize traffic scenarios and objects like cars and pedestrians. A U.S.-based company generated such datasets using GANs to replicate realistic road environments.

While the synthetic data appeared highly realistic, it was discovered that the GAN had replicated real-world license plates from the source training data. These synthetic license plates were not random but matched existing vehicles, posing a significant privacy and security risk.

This oversight raised alarms about the potential misuse of synthetic data for tracking vehicle owners or other malicious activities. Furthermore, the incident highlighted the importance of ensuring that synthetic data does not contain identifiable elements, even in domains like autonomous driving.

3. CUBIG’s Innovative Approach to Synthetic Data Generation

CUBIG effectively overcomes the limitations of traditional synthetic data generation methods through its advanced and innovative approaches, ensuring both data utility and privacy. CUBIG’s technology not only addresses issues like bias, privacy breaches, and the inability to capture real-world complexity but also sets a new standard for secure and high-performing synthetic data.

3.1. Differential Privacy Integration

CUBIG incorporates differential privacy into the synthetic data generation process, providing a mathematically rigorous privacy guarantee. Differential privacy ensures that the synthetic data produced does not expose or leak any information about individual records within the original dataset. Unlike traditional models that risk overfitting and unintentionally replicating sensitive information, CUBIG’s differential privacy implementation introduces controlled noise during the data synthesis phase. This ensures that even if adversaries attempt to reverse-engineer the synthetic data, they cannot infer details about specific individuals or records.

For example, in healthcare datasets, CUBIG’s differential privacy approach guarantees that no identifiable patient information (e.g., medical histories or unique MRI features) can be extracted, even while maintaining the utility of the data for AI training and analysis. This makes CUBIG’s synthetic data not only compliant with data protection laws such as GDPR and HIPAA but also trustworthy for sharing across teams, organizations, or industries.

3.2. Non-Access Technology

One of the unique features of CUBIG’s solution is its non-access technology, which eliminates the need to directly access the original dataset during the synthetic data generation process. This cutting-edge approach ensures that sensitive data remains entirely private and secure, as it is never transferred to or stored by CUBIG. Instead, CUBIG utilizes innovative algorithms and models to simulate the original dataset’s statistical and structural characteristics without interacting with the actual records.

Despite this data isolation, CUBIG’s synthetic data achieves over 99% similarity in terms of performance and utility when compared to the original dataset. This level of fidelity enables organizations to confidently use synthetic data as a 1:1 replacement for real-world data in AI model training, testing, and analysis while maintaining complete control over their sensitive information.

For instance, in financial applications, a bank can use CUBIG’s synthetic data for AI fraud detection or credit risk assessment without ever sharing customer data externally. This preserves privacy and confidentiality while ensuring that the generated synthetic data is highly accurate and reliable.

3.3. Reflecting Complex and Diverse Real-World Scenarios

Unlike traditional synthetic data generation methods that often fail to replicate real-world diversity and complexity, CUBIG’s approach creates synthetic data that reflects nuanced patterns and dynamic scenarios found in real datasets. This is critical for training robust AI models capable of handling diverse situations and edge cases.

For example, CUBIG can generate synthetic traffic data for autonomous driving systems that includes:
