Modeling ePassport (1)

We begin with UML sequence diagrams for BAC, DSO, MRZ and FACE:

• BAC:  Describe the Basic Access Control protocol used in ePassport. It ensures that only authorized parties can read personal information like the Machine Readable Zone (MRZ) or the passport photo.

        

• DSO: This protocol is used to get signed hashvalues of personal information like MRZ or the passport photo to validate received personal information. This protocol can be used only after BAC processed.
  

        

• MRZ: Depict the protocol to get the MRZ. Need to process the BAC and DSO protocol before.

       

• FACE: Depict the protocol to get the passport photo. Need to process the BAC and DSO protocol before.
