    摘要: A method for validating an interaction is disclosed. A first interaction cryptogram can be generated by a first device using information about a first party to the interaction and a second party to the interaction. A second interaction cryptogram can be generated by a second device also using information about the first party to the interaction and the second party to the interaction. Verifying each cryptogram can validate that the interaction details have not been changed, and that both the first party and second party legitimately authorized the interaction.
