This paper-oriented workshop scientifically addresses recent research efforts in the field of blockchain technology use for cross-organizational collaboration. The workshop focuses on the application of information and communication technology in order to enable organizational and governmental service provisions. The resulting technology-mediated processes are changing the delivery of private- and public services, as well as the broader interactions between citizens, governments, and organizations. More and more countries are considering e-governance solutions as a tool to improve the efficiency and transparency of their services. However, there exists a gap of understanding the support of trust and reputation via blockchain solutions that allow for immutable event traceability. The workshop aims for exploring systematic approaches for developing and interrelating blockchain-technology supported services, as well as increasing issues concerning blockchain-tech, enabled security and privacy of personal data use. In addition, technological advances in the field of big data analysis, blockchains for distributed application deployment, smart contracts, the Internet-of-Things, agent technologies, etc., offer new research directions in the blockchain-technology space for further improvements of existing solutions.

The goal of this workshop is to promote, establish and speed up blockchain-technology related research, and identify future research questions. Contributions should focus on clearly stated research questions covering the topics mentioned below.

The topics of interest for blockchain-technology research papers include, but are not limited to:

  • Security and Privacy Management of e-Governance Systems

  • (Smart) Government

  • E-Voting

  • Governmental Decision-making

  • E-Business

Demo about NFT-minting implementation for counterfeit prevention of luxury-product logistics and sales 

Abstract: The combination of data analytics and blockchain technologies can be used in designing and implementing transparent authentication systems for luxury products, thereby, improving the circular economy and logistics processes of such products. The circular economy is an important aspect of economic and environmental sustainability as it involves the reuse of products, reduction of wastage and optimization of processes. Currently, there are several issues with the authentication of luxury products such as complexity, high cost of verifications and lack of accurate verification results which have adversely affected the reuse and resale of such products. Hence, the problem of counterfeited luxury products persists. The focus of this paper is to design a platform that provides a transparent verification of high-value product authenticity and enables the re-use of such products through a transparent transfer of new and pre-owned luxury products. To achieve this, data analytics is applied to identify useful features for the digital authentication of high-value products such as luxury accessories. Blockchain requirement engineering is then applied in modelling to explore the use of technologies such as digital signatures, decentralized storage and time-stamping mechanism to realize the features that will guarantee transparency in the ownership and re-use of high-value products. Furthermore, this paper explores the existing blockchain technologies for realizing and implementing the developed requirements of the platform. The selected blockchain technology stack is applied in prototyping authentication systems for luxury products. The implemented platform is simulated to demonstrate the operations carried out on the platform, the user tasks involved and the estimated time requirements for their completion.   

2nd Keynote: Prof. Hella Kaffel Ben Ayed

Self-Sovereign Identities: basics and challenges for IoT: The digital identity has always been considered as the keystone for all online services and the foundation for building security mechanisms such as authentication and authorization. With the proliferation of digital services, digital identity in the center. The cost of identity and access management is increasing each year, Online users: more aware of value of their data & adequate privacy measures around them. Self-sovereign identity model (SSI) comes as the next step of evolution for the classical identity and access managements models. In this talk, we firstly remind the requirements of building identity management systems for IoT, which comprises scalability, interoperability, mobility, security and privacy. Then, we trace the identity problem back to the origin in philosophy and present the blockchain-based sovereign identity standard. Finally, we point out the promising future research trends in building IoT identity management.

Prof. Hella Kaffel Ben Ayed received Engineering, PhD, and University Accreditation Degrees (HDR) in computer science from the Faculty of Sciences of Tunis, University of Tunis El Manar (UTM). She is an Associate Professor in computer science at the Faculty of Science of Tunis, teaching graduate and undergraduate courses in networking and IT security, cyber security, IoT and Blockchain.

She participated in the setting up of various national and international collaboration projects. She served as guest editor for many scientific journals. She is a founding member of the IEEE Tunisia Blockchain Chapter. Her main research interests include security, privacy and identity management in IoT. She focuses on the use of Blockchain for cybersecurity, blockchain based marketplaces and Self-Sovereign identities.


BIOC’22 is intended to be a full-day virtual and online workshop divided into three sessions, in which around 6-8 full and 2 short scientific papers will be presented. Full papers will have a time slot reserved of 30 minutes (20 minutes for the presentation and 10 minutes for questions and discussions), and short papers will have a time slot of 15 minutes (10 minutes for the presentation and 5 minutes for questions and discussions). In addition, we plan to have a keynote speech held by an acknowledged expert in the field of blockchain technology in inter-organizational collaboration.
