GRABLOK: a novel graphical password authentication utilising blockchain technology

One of the most important security issues is unauthorised access to computer systems. The number of leaked passwords and credentials grows exponentially each year, showing that current protection systems and authentication methods are insufficient. Attackers are bypassing the state-of-the-art systems and gaining access to corporate environments as well as our personal accounts comprising confidentiality and threatening privacy. This work focuses on a new password authentication scheme utilising 3D graphical passwords and Hyper Ledger Fabric. The initial implementation shows that this method is promising and can offer users and organisations better security minimising the risk of stolen credentials.
