A composer model that allows to exchange data in a confidential way.

To test the model use the online playground: https://composer-playground.mybluemix.net/

The model is composed just by one participant (Person)

Person Model:

participant Person identified by pID {
    o String pID
    o String firstName
    o String lastName
}

while the only asset is DataAsset

asset DataAsset identified by dataHash {
    o String dataHash
    o String value
    --> Person owner
    o String [] auth
}

The strict ACL rules do not allow unathorized users to see data that belongs to others, achieving confidentiality.
