The method utilizes a passport identification number as an element of a homomorphic encryption used to stamp a passport with country entry/exit data to form a digital representation of a subset of information in the passport. As a result, exchange of the digital representation is permitted to allow a selective transfer of information without exposing a user-sensitive passport identification number. The homomorphic encryption comprises a support for exposing a trusted photo and a trusted group containing country travel entry and exit information. The digitally signed passport stamp may then be used to provide verification of the individual by ensuring linkage to that user's passport. The individual's identity and passport verification may occur unconnected, i.e., without having to connect to a central database.
