Privacy and Data Protection

Evaluating and delivering on-chain and off-chain privacy solutions and protocols

Privacy and Data Protection

Despite common misconceptions, blockchain technology does not provide confidentiality and privacy, exactly the opposite is true. Blockchain is designed to be transparent. The focus on integrity of data in the decentralized model requires all the consensus participants to share information. Anything recorded onto a blockchain can be arbitrarily read without any restrictions by all participants. This places the new technology at odds with the new and onerous privacy and data protection regulations that all assume centralized controller-based data processing. Regulatory guidance on reconciling this and other potential conflicts is currently limited.

If you need information recorded in a blockchain to be confidential, this could be accomplished through the use of encryption, by anonymizing or minimizing information to be stored, and through other similar approaches.

Paralleling blockchain technology’s growth over the past decade, personal data protection has seen a sharp uptick in global attention as a general policy and regulatory concern.

Organizations leveraging distributed ledger / blockchain / web3 technologies to collect, use or disclose personal information must take care to remain informed and compliant to requirements under relevant laws and data protection expectations of their clients. Handling privacy issues and properly applying laws increasingly contribute to a venture’s success or failure.

Privacy and Data Protection

Cryptosec Privacy and Data Protection Services

In the rapidly evolving world of Web3, crypto, and blockchain, privacy and data protection are more critical than ever. The unique characteristics of these technologies, such as decentralization and immutability, present both opportunities and challenges when it comes to managing and protecting data. At Cryptosec, we offer a comprehensive suite of sensitive data protection services designed to help you navigate these complexities and ensure that your operations are compliant and secure.


Cryptosec helps you conduct privacy impact assessments (PIA) or data protection impact assessments (DPIA) before implementation or release in order to:

  • Ensure conformance with applicable legal, regulatory, and policy requirements
  • Identify and evaluate the risks of privacy breaches or other incidents
  • Identify appropriate privacy controls to mitigate unacceptable risks

See more here: PIA and DPIA


Our team of experts can provide advice and guidance on a wide range of privacy and data protection issues, from designing privacy-friendly systems to complying with complex regulations like the GDPR. We can help you understand your obligations, identify potential risks, and implement effective privacy and data protection measures.

Compliance Advisory

Advice on various aspects of privacy and data protection compliance, such as:

  • How to identify data controllers and data processors in various blockchain technology implementations
  • Understand territorial implications for distributed blockchain networks
  • Identify when cross-border data transfers occur and potential restrictions on them
  • Applying criteria for legitimate reasons for processing personal data to blockchain use cases
  • Reconciling transaction immutability and data preservation in blockchain applications with individuals’ rights

Anonymity and Pseudoanonymity Assessments

Cryptosec rigorously and quantitatively assesses the degree of anonymity and pseudonymity in various solutions and provides perspectives on how they affect the applicability of various data protection and privacy laws.

Sensitive Data Discovery and Classification

In the vast landscape of organizational data, sensitive information can often be scattered across various systems and databases. Identifying and classifying this data is a crucial first step in establishing robust data protection measures. Cryptosec’s Sensitive Data Discovery and Classification services are designed to help you uncover and categorize your sensitive data, laying the foundation for effective data protection.

Our team of experts employs advanced tools and methodologies to scan your systems, identify sensitive data such as personally identifiable information (PII), financial data, or intellectual property, and classify it based on its sensitivity level. This process not only helps you understand where your sensitive data resides but also provides insights into how it should be handled and protected.

Advanced Privacy and Data Protection Services

Statistical disclosure control is a critical aspect of data privacy. It involves implementing measures to prevent the identification of individuals from statistical summaries of data. However, as data becomes more complex and interconnected, traditional methods may fall short. Even non-sensitive data, when correlated, can inadvertently reveal sensitive information.

Differential Privacy is a groundbreaking approach that addresses this challenge. It provides a mathematical framework for quantifying privacy, allowing organizations to balance the utility of data analysis with the need to protect individual privacy. It adds a controlled amount of randomness to the data, making it virtually impossible to identify individuals while still allowing meaningful analysis.

At Cryptosec, we offer advanced services to help organizations navigate this delicate balance. Our team of experts will work with you to understand your needs, design and implement a differential privacy strategy tailored to your specific context, and provide ongoing support to ensure its effective operation. 

Data Anonymization Services

Cryptosec’s Data Anonymization services provide a robust solution to this challenge, enabling you to utilize your data for insights without compromising privacy.

Our Data Anonymization services encompass a range of techniques including data masking, tokenization, and encryption. Data masking involves replacing sensitive data with fictitious yet realistic data, preserving the utility for testing or development purposes. Tokenization replaces sensitive data with non-sensitive substitutes, known as tokens, while maintaining a secure link to the original data. Encryption transforms data into a code, which can only be accessed with a decryption key.

Each of these techniques serves a specific purpose and is applied based on the nature of the data and the specific use case. Our team of experts will work with you to understand your requirements and implement the most suitable anonymization techniques.
