method for communicating digital messages by associating a message with subject material

摘要

the invention proposes a system and method for transmitting a message, allowing a sender (designated by an identifier) to send digital content to one or more recipients (designated by one or more identifiers), with the content being associated with at least one subject material (each designated by at least one individual authenticator). thus, to send a message, the sender implements at least one individual authenticator of the subject material, which is discriminating and has intrinsic characteristics of each subject material, and serves to fix or anchor the content to be transmitted. to be able to access the content of the message, the recipient must provide the server with not only its identifier, as in any current messaging system, but also an individual authenticator with the same subject material that was used by the sender at the time of the creation of the message. an individual authenticator of the subject material can be one or more images of the subject material's authentication area, or any metric extracted from said images, partially characterizing the microstructure of the subject material.
