AI meets Distributed Ledger: Building marketplaces, sharing data and breaking silos

By Nils Klute, Specialist IT Editor and IoT Project Manager at eco – Association of the Internet Industry

Artificially intelligent (AI) decisions must be trustworthy for all parties involved. Not only to gain the desired acceptance and acceptability, but also to advance Europe as a location for AI, says Prof. Ali Sunyaev. In an interview, the professor of Computer Science at the Karlsruhe Institute of Technology (KIT) explains what makes AI trustworthy and reliable.

Prof. Sunyaev, why does artificial intelligence (AI) need to be trustworthy?

Because trustworthiness makes AI more reliable for all parties involved. Not only to prevent harm, but also to be able to understand decisions and predictions of AI when needed or in certain contexts.

What does that mean exactly?

For example, that an AI complies with rules, laws, and regulations, upholds ethical, social, and societal norms, and, of course, is technically robust.

Why does the industry need such an AI?

To give you an example: In a factory, AI autonomously controls systems and devices. If humans and machines are then to work side by side, it must be ensured that an AI is able to distinguish between employees and objects at all times. If real-time processes are intelligently automated, this is not only technologically challenging, but also an issue of safety. When AI is used at the management level, it should be ensured that predictions and recommendations of AI follow ethical and social principles, as must also economic activity.

What are the key issues?

AI is still far too often a black box in applications. How neural networks make predictions is difficult or impossible to understand, even for experts. By the way, in some contexts this is also desirable or even required – in most cases, however, the opposite is the case. Furthermore, AI is by no means a neutral advisor. Every decision is tainted by prejudice, a bias to which the data processed by an algorithm are themselves subject. For reasons like these, IBM announced in early June that it would no longer offer facial recognition systems for the police.

And what is a possible solution?

You could make AI more reliable by combining it with Distributed Ledger Technology (DLT)…

… so algorithm meets blockchain?

Not quite, the concept of block chain also provides for algorithms. Rather: AI applications and DLT systems can be combined.

What are the advantages?

AI can detect vulnerabilities in DLT systems, for example. Examples are the detection of bugs in Smart Contracts or a game theoretical analysis of the fairness of DLT systems. On the other hand, DLT systems can be transferred to AI, for example to document decisions or predictions in a completely traceable manner, to ensure the integrity of training data, to protect access rights and manage identities, so that it is always clear what an AI is allowed to do.

What applications are there for this in industry?

Decentralized data marketplaces can be set up, information can be securely shared and silos can be broken. For example, Federated Learning allows AI agents to be trained locally where the industry stores data. In the end, companies do not share information, but rather aggregate AI models, whose integrity in turn is ensured by the DLT. In this way, competitive interests are safeguarded. Even if too little training data is available in a company, the distributed approach solves the dilemma.

How can this help in the Service-Meister project?

Used in maintenance, DLT can ensure that training data is trustworthy. Or, if service data is only available in small quantities in decentralized and locally distributed form at user companies, Federated Learning could help to teach AI applications in the first place. Aggregated and mature AI models can be exchanged in a more tamper-proof way, which, for example, enables better predictions for predictive maintenance. A result that benefits all participants in the service ecosystem for Industry 4.0 – without having to disclose their data.

How well do industrial services and trustworthy AI fit together for you?

Trustworthy AI from Germany and Europe has the potential to become a successful product. Even a project such as Service-Meister around the B2B platform market is certainly exciting here – not only to advance intelligent machine maintenance, but also to promote Europe as a location for reliable AI.

Thank you for the interview!
