Abstract

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.

Claims20

Dependent claims

An electronic message transmission method comprising the following steps:

initially, choice by a sender of at least one material subject having at least one authentication area showing a microstructure at a given observation magnification, then acquisition or implementation of at least one first image of the authentication area,
recording, by the sender, of the electronic message to be transmitted on a server system,
recording on the server system of at least one identifier of at least one recipient of the message, each identifier being associated with the message to be transmitted,
notification to each recipient of the existence of a message,
acquisition of at least one second image of the authentication area of the material subject, the second image being acquired with a quality substantially equivalent to that of the first image so that the first and the second images contain a substantially equivalent level of information relating to the authentication area,
alignment of the first and second images and determination from the first image of a first unitary authenticator of the material subject and determination from the second image of a second unitary authenticator of the material subject,
comparison of the unitary authenticators,
transmission to the server system of an identifier of at least one recipient associated with the second unitary authenticator,
in case of similarity between the first and second unitary authenticators and matching between the recipient identifier recorded in the server system and the transmitted recipient identifier, transmission to the recipient of the message associated with its identifier and with the unitary authenticator.

The electronic message transmission method comprising the following steps:

initially, choice by a sender of at least two material subjects each having at least one authentication area showing a microstructure at a given observation magnification, then acquisition or implementation of at least one first image of the authentication area of each material subject,
recording of the electronic message to be transmitted on a server system,
implementation of at least two material subjects each having at least one authentication area showing a microstructure at a given observation magnification,
implementation of an alignment reference,
alignment of each first image with respect to the alignment reference and, jointly or not with the alignment,
determination from each first image of a first unitary authenticator of each material subject, said unitary authenticator comprising an image of the authentication area and/or an authenticator derived from this image,
recording on the server system of the first authenticator of each material subject,
acquisition of at least one second image of the authentication area of at least one candidate material subject, the second image being acquired with a quality substantially equivalent to that of the first image so that the first and the second images contain a substantially equivalent level of information relating to the authentication area,
alignment of the second image with respect to the alignment reference and, jointly or not with the alignment,
determination from the second image of a candidate unitary authenticator of the candidate materiel subject,
transmission to the server system of an identifier of at least one recipient associated with the candidate authenticator,
comparison of the candidate unitary authenticator with the first unitary authenticators recorded in the server system and, in case of similarity between the candidate unitary authenticator and a first unitary authenticator, transmission of the message to the recipient whose identifier is associated with the candidate unitary authenticator.
