Overcoming Challenges in Sharing Data Across Borders and Industries in Europe

Updated: Jul 3

In an increasingly interconnected world, the ability to share data seamlessly across borders and industries has become paramount. Europe, with its diverse landscape of countries and industries, faces unique challenges in this endeavour. However, advancements in technology coupled with innovative approaches are paving the way for more efficient and secure data sharing practices. In this blog, we delve into the complexities surrounding data sharing in Europe, the challenges it presents, and the promising technologies and approaches poised to revolutionise this process.

Current Landscape and Challenges in Data Sharing

Data sharing across borders and industries in Europe is not without its hurdles. These challenges stem from various factors including regulatory differences, data protection laws, technical interoperability issues, and cultural differences among others.


  1. Regulatory and Legal Frameworks: One of the primary challenges is navigating the complex regulatory and legal frameworks governing data sharing across European countries. The General Data Protection Regulation (GDPR) sets strict guidelines for the processing and transfer of personal data within and outside the European Union (EU). Ensuring compliance with GDPR while facilitating cross-border data sharing requires careful consideration and often involves lengthy legal processes.

  2. Data Protection and Privacy Concerns: Protecting the privacy and security of data is paramount. Concerns over data breaches, unauthorised access, and misuse of personal information pose significant barriers to cross-border data sharing initiatives. Ensuring robust data protection mechanisms and maintaining compliance with stringent privacy regulations is crucial.

  3. Technical Interoperability: Achieving seamless data exchange between disparate systems and platforms presents a significant technical challenge. Differences in data formats, protocols, and standards hinder interoperability, making it difficult to integrate and harmonise data from diverse sources.

  4. Cultural and Organizational Barriers: Cultural differences and organisational silos further complicate the sharing of data across borders and industries. Resistance to change, lack of trust, and competing priorities often impede collaboration and hinder the sharing of valuable insights and resources.

Current Approaches and Technologies

Despite these challenges, several approaches and technologies are being employed to facilitate cross-border data sharing in Europe:


  1. Data Sharing Agreements and Frameworks: Establishing bilateral or multilateral data sharing agreements and frameworks can help streamline the process and provide legal clarity regarding data sharing practices. Initiatives such as the European Data Governance Act aim to create a harmonized framework for data sharing across the EU.

  2. Secure Data Exchange Platforms: Leveraging secure data exchange platforms and networks can help ensure the confidentiality, integrity, and availability of shared data. These platforms often employ encryption, access controls, and audit trails to safeguard sensitive information during transit and storage.

  3. Data Harmonisation and Standardisation: Efforts to harmonise and standardise data formats, protocols, and vocabularies facilitate interoperability and seamless data exchange. Initiatives such as the European Interoperability Framework (EIF) promote the adoption of common standards and specifications across European countries and sectors.

  4. Blockchain and Distributed Ledger Technology (DLT): Blockchain and DLT offer decentralised and tamper-resistant platforms for secure data sharing and collaboration. By providing immutable records and consensus mechanisms, these technologies enhance transparency, trust, and accountability in cross-border data transactions.

  5. Artificial Intelligence (AI) and Machine Learning: AI and machine learning algorithms can analyse vast amounts of data to extract valuable insights and patterns. By automating data processing tasks and uncovering hidden correlations, AI-driven solutions enable more informed decision-making and enhance the efficiency of cross-border data sharing initiatives.

Emerging Technologies and Approaches

Looking ahead, several emerging technologies and approaches hold promise for revolutionising cross-border data sharing:


  1. Federated Learning: Federated learning enables collaborative model training across distributed data sources without the need to centralise sensitive information. By aggregating model updates locally and preserving data privacy, federated learning allows organisations to leverage insights from diverse datasets while maintaining data sovereignty.

  2. Secure Multiparty Computation (MPC): MPC techniques enable parties to jointly compute functions over their private inputs without revealing sensitive data to each other. By preserving confidentiality and privacy, MPC facilitates secure collaboration and analysis of sensitive information across borders and industries.

  3. Homomorphic Encryption: Homomorphic encryption enables computations on encrypted data, allowing parties to perform operations while keeping the underlying data confidential. By preserving privacy and confidentiality throughout data processing operations, homomorphic encryption enables secure cross-border data sharing and analysis.

  4. Decentralized Identifiers (DIDs): DIDs provide a decentralised approach to identity management, allowing individuals and entities to maintain control over their digital identities. By enabling self-sovereign identity and authentication, DIDs facilitate trusted interactions and data sharing across borders and industries.

The Role of European Research and Innovation Projects

European research and innovation projects play a crucial role in advancing technologies and approaches for cross-border data sharing. Projects such as DS2 (Data Spaces | Sharing) are developing innovative solutions to break down silos and foster collaboration across sectors. DS2 is creating an Intersector Data Space Toolkit to provide organisations with the necessary tools and resources to overcome barriers to data sharing and interoperability. By promoting standards-based approaches and facilitating the exchange of best practices, projects like DS2 contribute to the development of a more connected and data-driven European ecosystem.


For those interested in staying abreast of advancements in data sharing in Europe, several sources can provide valuable insights and updates:


  1. European Commission: The European Commission's Digital Single Market website offers information on policies, initiatives, and funding opportunities related to data sharing and digital innovation in Europe.

  2. European Data Strategy: The European Data Strategy outlines the EU's vision for a single European data space and provides insights into key initiatives and priorities for unlocking the value of data across sectors.

  3. European Data Portal: The European Data Portal provides access to open data from public sector organisations across Europe, facilitating transparency, collaboration, and innovation.

  4. Eurostat: Eurostat, the statistical office of the European Union, publishes data and reports on various aspects of European society and economy, offering valuable insights into trends and developments in cross-border data sharing.


In conclusion, while sharing data across borders and industries in Europe presents numerous challenges, advancements in technology, coupled with collaborative efforts and innovative approaches, are paving the way for more seamless and secure data exchange practices. By embracing emerging technologies, fostering collaboration, and promoting interoperability, Europe can unlock the full potential of its data ecosystem and drive innovation and growth across sectors.
