Abstract
When a controller of a client server updates component data Dto component data D, the controller creates in a distributed ledger which is a first proof chain, a record (Age [3]) including a hash value of the component data D. Then, the controller generates a terminal hash value which is a hash value of a terminal record (Age [3]) in the first proof chain. The controller has the generated terminal hash value stored in a record in a distributed ledger which is a second proof chain, and associates the first proof chain and the second proof chain with each other.
