About the possibility of embedding the distributed ledger technologies into the systems of mixed workflow

Abstract

The paper presents a study on the possibility of using distributed ledger technologies in managing various business processes based on electronic document management systems. In the finance and trade sphere, the type of distributed ledger technology, blockchain, is already presented as a real alternative to the existing infrastructure, however, the experience of developing and implementing such solutions in electronic document management systems is currently insufficient. The model of hybrid workflow proposed earlier by the authors of the article has a number of advantages over usual scheme of information exchange, and combines equal document protection in paper and digital form using cryptographic and biometric methods. The described distributed ledger-based hybrid workflow scheme also provides decentralized information storage, a fixed size of data blocks stored and transmitted by users, generation of cryptographic keys using biometric images of authorized users, and identification of subjects that performed various actions on document regardless of its type format. The authors also considered possible problems that might be encountered in the development and implementation of such an information interaction scheme.
