Identify the required types of synthetic data

Synthetic data generation is a process of using artificial intelligence (AI) algorithms to produce mock data, fully artificial or based on real data, for the purposes of analytics. These are the most popular types of synthetic data generation:

  • Fully AI-generated synthetic data is created from scratch using machine learning to mimic the statistical properties of the original data while ensuring anonymity. It’s especially useful for model training and data sharing.
  • Rule-based synthetic data is generated based on predefined rules and constraints to meet specific business needs. Most often, it’s used for advanced analytics that requires controlled data qualities.
  • Synthetic mock data mimics real data’s structure and format without using actual information. Requiring minimal investments, it often serves as test data for software development. 


Synthetic datasets are free from personally identifiable information (PII). Since it can’t be linked back to specific individuals, synthetic data isn’t subject to regulations like the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).


Before you start scouting for synthetic data companies, you should figure out whether you need to generate structured or unstructured data.

Structured vs. unstructured data

Structured data

Structured data consists of organized, quantitative datasets in a tabular format with interconnected data points. It’s often categorized chronologically for efficient analysis of human-based behavior, financial data, and time-based trends.


Examples include:

  • Names
  • Addresses
  • Contact data
  • Payment information (credit card numbers, invoices, etc.)
  • Financial performance


To produce synthetic structured data, a generative machine learning model is used on a relational database with real data. This model is designed to create a new dataset that mirrors the original in mathematical or statistical terms. 

Unstructured data

Unstructured data is qualitative data without a predefined format. Unlike structured data, it does not fit neatly into traditional database fields and cannot be processed quickly. Managing this type of data requires using non-relational (NoSQL) databases designed to handle less structured information. 


Companies use advanced machine learning, computer vision, NLP, and Generative Adversarial Networks models to extract patterns and insights from unstructured data.


Examples include:

  • Textual data: emails, social media posts, web pages.
  • Images: visual information contained in images and photographs.
  • Audio: speech or music recordings.
  • Video: video data, combinations of images, and audio.
  • Sensor data: temperature and accelerometer data, IoT sensor outputs.
  • Social media content: posts, comments, images, videos. 


After deciding on structured vs. unstructured data, the next step is to clarify exactly why the company needs synthetic data generation.

Determine your company’s synthetic data requirements

A synthetic data provider you choose should align with your analytical, operational, and data privacy requirements. Different use cases call for different synthetic data approaches; however, many providers support limited methods. Only a few cover multiple synthesis techniques. 

Identify the use cases

As we said, structured and unstructured datasets serve different purposes. Let’s look at the potential use cases for synthetic data depending on the data type.

Structured synthetic data use cases:

  • Test data. Synthetic data is used to create realistic test environments for software development and quality assurance without the risk of compromising real data.
    • Data twins. Organizations can produce life-like data to mirror real system performance and use it for quality control (identifying the most efficient configurations, manufacturing conditions, application settings, etc). 
  • Algorithm improvement. Synthetic generation data can be used to train algorithms to detect threats, prevent fraud, and offer personalized recommendations.
  • Product demos. Companies use synthetic data to showcase their product’s capabilities without exposing real customer data.
  • Data sharing. Synthetic data facilitates safe internal and external sharing for collaboration and innovation.
  • Clinical research. In this area, synthetic data helps analyze trends, demographics, and treatment outcomes while safeguarding patient privacy. 

Unstructured synthetic data use cases:

  • Natural language processing (NLP) and training. Synthetic data is crucial for training and fine-tuning machine learning models for text and speech recognition and generation without collecting real-world data.
  • Computer vision (video). Organizations can train computer vision software with a broad range of artificial image and video data.
  • Audio. Synthetic data generates realistic yet artificial sounds or speech patterns for training and testing voice recognition and sound analysis systems.


Using various methods, you can tweak or expand the produced data to make training datasets more diverse and reduce the risk of algorithmic bias.


Also, it’s important to think about how practical artificial data is.

Consider data utility

Synthetic data must replicate the patterns, distributions, and qualities of the original datasets. When choosing a provider, double-check that the data they generate can stand in for the actual data. The tool must be useful for the intended practical purposes, like machine learning training or clinical research.

Generated data must preserve referential integrity and keep the statistical and structural characteristics of the original dataset, while protecting sensitive information. The Syntho platform, equipped with smart de-identification features and consistent mapping, makes this level of data transformation possible.

Before fully committing, it’s wise to test a sample of artificial data. Inspect the created datasets for potential errors and inaccuracies, as well as consistency and reliability for different dataset sizes. Automated assessment tools can help you spot discrepancies between the generated and real data.

The platform should be flexible enough to handle all kinds of scenarios, even those beyond its original intended use. Have your team experiment with different use cases before committing. For example, a clinical research team might also want to have artificial datasets tested for marketing purposes or security algorithm training.

Synthetic data companies on your list should support different file formats and database types. Most business software can handle traditional formats like CVS, JSON, and XML, as well as SQL and NoSQL databases. But it’s always a good idea to double-check the documentation or confirm it with the provider. Some companies also offer APIs to integrate their platform with your existing workflows and formats.

Focus on data privacy requirements

Synthetic data is entirely artificial and contains no trace of the original PII. This means it’s not subject to GDPR (UK-GDPR), HIPAA, and the California Consumer Privacy Act.


How to confirm that? Request documentation on the company’s synthetic data generation process. Make sure the provider has relevant certifications and undergoes regular third-party audits. 


Another smart move is testing the generated output to check for original identifiers. As an extra precaution, try to re-identify the artificial data by looking at combinations of attributes and alongside other datasets. 

Check for the ease of use

A user-friendly interface is a must for synthetic data software. Look for a provider that makes it easy to generate synthetic data on different operating systems, even if you’re not a coding expert. We recommend focusing on software with drag-and-drop features and AI-enhanced scanners to identify PII in datasets automatically without requiring too much manual input.


The software should integrate with your existing IT infrastructure and business tools with minimal disruptions or refactoring. Ideally, the synthetic data company you partner with should offer assistance during setup to ensure it aligns with your workflow.


Expect your provider to offer detailed manuals and training to help your employees use the tool effectively. And don’t forget about technical support, which should be easily accessible whenever you need it.

Synthetic data providers vs. open-source vs. custom software: key considerations

Each option presents its own considerations and trade-offs, addressing diverse needs and priorities within organizations. So, let’s explore how commercial software and custom tools stack up against open-source tools in synthetic data generation.

Open-source tools

Free, open-source synthetic data generation tools are the most budget-friendly. Another major perk is that you can modify the code to fit your needs. Open-source projects often boast active developer communities where users can seek advice and share solutions.


However, even though open-source tools are low-cost and handy, they don’t always provide high-quality data. They also lack the advanced automation capabilities found in their commercial counterparts. For example, they rarely offer built-in features to assess or optimize the generated output. 


What’s more, these tools are complex and usually demand a certain level of coding skills. You will probably need a dedicated IT expert to set up, configure, and maintain them.


By the way, at Syntho, we recently conducted a comprehensive comparative analysis of our platform vs. open-source synthetic data generators. You can read about the criteria and conclusions in this article.

Commercial software

Commercial synthetic data software caters to business needs. It’s usually designed for users without deep technical expertise. Business-focused solutions often have intuitive interfaces, pre-built workflows, and templates. 


Synthetic data companies make sure their software integrates with other IT infrastructure and CI/CD tools. Vendors also offer ongoing technical support and take care of software maintenance so it remains effective and secure over time.


These platforms can be deployed on-premise or accessed through cloud-based subscription services. The implementation process can differ depending on your company’s size and complexity. Finally, business tools offer a range of pre-built customization options, but they might not cover all possible use cases.

Custom development

Organizations might consider building synthetic data generation tools to meet their unique operational needs. However, this route makes practical sense only if existing synthetic data solutions don’t work with their specific data types, formats, or data governance standards. 


Developing a tool like this takes time and money. And after it’s built, you must take care of its maintenance and updates. Worse, there’s no guarantee that your custom machine-learning algorithm will generate compliant, high-quality data.


Given all that, partnering with an experienced synthetic data company is typically the best option for most organizations. Below is a shortlist of the top seven providers we recommend for the job.
