The first letter in SEDIMARK stands for Secure. How does Security is involved into SEDIMARK? In this blog post we will present an overview of the Security and Trust Domain within SEDIMARK!

Nowadays, the proliferation of large amount of data requires to ensure the security and integrity of the information exchanged. In the traditional way, a centralized data marketplaces face security challenges such as data manipulation, unauthorized access, and lack of transparency. 

In response to these challenges, Distributed Ledger Technology (DLT) has emerged as an alternative solution, offering decentralized (see "The letter D in SEDIMARK"), immutable, and transparent data exchange mechanisms.

Enhancing Security in Data Exchange

Centralized data marketplaces are susceptible to various security vulnerabilities, including single points of failure and data breaches.

Using DLT mitigates these risks: the control is decentralized and the cryptographic mechanisms ensure the security.

In SEDIMARK Marketplace the participants can securely exchange data without relying on third-parties (intermediaries), reducing the risks for unwanted data manipulation or unauthorized access to their data (or, more in general, their assets).

Security Features

SEDIMARK will employ (... or is it already?!) key features enabled by DLT, such as smart contracts, Self-Sovereign Identity (SSI), and cryptographic primitives to enhance security and transparency of the Marketplace.

The Smart Contracts automate the execution of agreements between parties, ensuring trustless and tamper-proof transactions.

SSI allows users of the Marketplace to retain full control on their own identity, without relying on centralized authorities (see A Matter of Identities).

Finally, the cryptographic primitives are the underlying functions to ensure data security and integrity.

Ensuring Data Origin

Using cryptographic functions, such as digest, ensures the creation of a mathematically unique fingerprint for a certain asset.

Recording (or "anchoring") such value onto the DLT allows to achieve an immutable data trail.

So, every user can be certain of the origin of the asset that is purchasing.

This also leads to additional transparency enhancing the Trust in this distributed marketplace.

SEDIMARK exploits traditional cryptographic mechanisms as well as DLT to freshen up data (asset!) exchange mechanism and to secure the Marketplace.

Data has become a growing business of the utmost importance in the recent years of IoT technological expansion, driving crucial decision-making systems at the EU and global level, impacting all domains: industry, politics and economy, society and individuals, as well as the environment.

As the volume of instreaming data being collected, stored and processed is constantly expanding, most systems and techniques to absorb efficiently, appropriately and in a scalable manner such data, are lacking or rapidly overwhelmed by the technological revolutions. Furthermore, of great concern, the quantity of circulating private and sensitive information linked to individuals and organizations. Consequently, the data is insufficiently managed and maintained, too often misunderstood due to its complexity, lacking in high quality standards, ill-adapted to large-scale AI analytics, which in turn leads to inappropriate handling, sharing and misuse of data across borders and domains, even though they conform to European RGPD and FAIR* principles!  

For this reason, SEDIMARK uses a data orchestrator called “” to : (i) better organize integration of multiple data sources, applications, toolboxes, services and systems, (ii) render scalable the data workflows to improve performance and reduce bottlenecks, (iii) ensure data consistency, harmony and highest quality, (iv) guarantee data privacy and security compliant with EU regulations by anonymization and decentralized systems, and finally to (v) minimize and mitigate potential risks by automating schedules for data and system maintenance, monitoring and alerting procedures. On top of all, the orchestrator enables all actors of the data to easily manage, adapt and visualize the data situation.

As inferred by the project acronym itself, SEDIMARK is a data-driven project, joining the global trend where individuals and companies produce tons of data on a daily basis.

The initial impulse in any initiative of this type involves focusing on the purely operational and organizational aspect. However, if we stop to think about the treatment carried out on these generated and collected data, the imperative need to dedicate space to the ethical section of its manipulation falls under its own weight.

Hence, the European Commission recommends for this kind of project to check periodically potential ethical issues. First, to make sure that the project does not use personal data (or if it happens to use that this is in compliance with GDPR and other relevant requirements) and second because this specific project will use AI-based solutions and thus it is important to make sure that they are in line with the standards in this area.

What does an Ethics Board do?

Attention to these ethical issues should not fall exclusively on the members of the consortium, who are ultimately interested parties in the process. That is why it is advisable to have opinions from voices external to the project, with proven experience in the project's work areas, capable of evaluating with a critical and well-trained eye the work carried out by SEDIMARK to preserve an ethical approach. These people make up the so called ethics board.

In the context of SEDIMARK, such Ethics Board will proactively support the development of the project, act as a knowledge and guidance forum, and provide advice to the consortium on how to exploit knowledge created by the project.

Hence, SEDIMARK partners will invite the Ethics Board members on a regular basis to discuss about ethical aspects taking into account the project evolution, keeping them well informed of all relevant publications and/or events SEDIMARK-related.

Specific goals for SEDIMARK’s Ethics Board

The purpose of every Ethics Board Member participation is to contribute to a series of objectives through the provision of assessment to the project consortium on topics such as:

  • Help validate and provide feedback to the technical designs of SEDIMARK.
  • Assist the consortium in the elaboration of ethical-based reports, with a strong emphasis on personal data, AI and ethical incentivization of data sharing.
  • Active participation in project conferences, workshops and meetings that require of their participation.
  • Participate in discussions on open topics of your interest and for SEDIMARK:
    • give specific opinions,
    • seek alignment and convergence with other initiatives,
    • the adoption of standards in the sector and the reuse of previous work,
    • help maximise the benefits for a wide spectrum of stakeholders.

For all of the above, Ethics Board members will act as advisors in order to follow ethical issues, based on the report that the consortium will prepare on a yearly basis. Such report specifically focuses on explaining data protection issues (if any) and compliance with AI ethical standards. Its initial iteration was already issued during the first year of the project execution and will be a subject for updates along the way.

This deliverable is a first version of the deliverable named “Edge data processing and service certification”.

The work has focused on identifying the building blocks required to develop a framework for deploying AI-based data processing and sharing modules at edge data sources, considering edge-cloud interactions following MLOps principles. It involves analysing various ML frameworks such as TensorFlow, PyTorch, tinyML, and edgeML, while addressing security and privacy concerns by implementing adaptive edge anonymization or tagging of sensitive data.

At this stage of the project these topics are still quite exploratory; this report focuses thus more on challenges, considered options and possible implementation choices. The last version of this deliverable, which is due M34 (July 2025), will provide all the details about the technical choices and their implementation.
