Abstract
Computer implemented systems and methods are detailed for establishing delegated authorisation. The methods of verification and generation of delegated authorisation tokens comprise obtaining a first delegated authorisation token of a chain of delegated authorisation tokens. Further delegated authorisation tokens of the chain of delegated authorisation tokens are generated based on the preceding delegated authorisation token in the chain of delegated authorisation tokens. If verifying the validity of a delegated authorisation token, the validity of the first delegated authorisation token based on a comparison of one of the delegated authorisation tokens in the chain of delegated authorisation tokens and a predetermined value.
