The invention proposes a system and a method for transmitting a message that allows a sender (designated by an identifier) to send a digital content to one or more recipients (designated by one or more identifiers), the content being associated with at least one material subject (each designated by a single authenticator). Thus, to send a message, the sender implements at least one single authenticator of the material subject, discriminant and intrinsic characteristic of each material subject, which serves to anchor the content to transmit. To be able to access the content of the message, the recipient must provide the server not only its identifier, as for any current messaging system, but also a single authenticator with a same material subject that was used at the time the sender created the message. A single authenticator of a material subject may be one or more image(s) of the authentication region of the material subject or any metrics taken from said image(s) and partly characterizing the microstructure of the material subject.

Method for digital messaging associating a message with a material subject

A processing method in a system including first and second computer devices, the second device receiving batches of data to be sorted into N categories is provided. According to the method, an algorithm for sorting into N categories, which is stored in the second device, is executed in the second device and determines a respective category from among the N categories for each batch of data; and an action is selectively triggered according to the category determined for the received data batches, respectively. The sorting algorithm may previously be obtained according to the following steps: i/ a data sample is generated for each of the N categories; ii/ according to the data received by the first device for the data samples, an algorithm for sorting into N categories is determined by the first device according to consecutive iterations of a definition algorithm executed in the first device.
