DataModel contains a
Proof that contains all the information of its integrity along with the method with which the
Proof should be verified.
In this case I designed a
JWS type of proof that can be generated by using a
ProofGenerator object that contains the private key to calculate the
Proof. However each time a
DataModel must be verified a public key must be provided by the verifier, which means that the public key (that is the information needed for the verification) is not included into the
A possible solution would be to define a new
ProofMethod class that contains all the information to perform the verification and pass it to the
verify method of the
Proof that contains the logic to do that.
Is there a better way to design this mechanism by including all the necessary information in the
Proof class to do the verification knowing that the information needed for that must be provided and not included (in this case the public key) when the
Proof is created?
Another problem is that who receive the
DataModel must recognize the
Proof type otherwise it is not able to provide the
ProofMethod necessary to do the verification.
