In a message exchange between an emitter and a user, the message is digitally signed. By allowing the emitter to see a part of the message, the complete blindness of the signatory is avoided and he is permitted to see a part of the signature. The signature is called blind. The user sends only a part of the message to the emitter sign. The emitter can then incorporate the part of the signal in the information elements necessary for recognition of the signal which once produced, can only be verified, with the help of the entire message, of which a part has been seen by the emitter.
