Description

Invention background

The present invention relates to the general field of traceability, that is to say to information relating to the various actions carried out on a product before its marketing and / or consumption. More particularly, the present invention relates to the field of food traceability carried out for foodstuffs intended for human or animal consumption.

There is currently a need to have information on the course and the processes having been implemented during the manufacture or during the preparation of products, in particular food. The purpose of such traceability is therefore to reassure the user or the consumer about the origin of the product they buy or consume. Furthermore, such traceability also makes it possible to ensure the quality of the product or, failing this, to quickly identify the anomalies that have occurred during manufacturing or preparation.

Currently, there are labels, for example organic, intended to guarantee, with the consumer, the respect of a certain number of rules during the development of a product. However, such labels remain general, and they cannot account for all the interventions implemented in the development of a product. Thus, the controls, if there are any, are carried out randomly and from time to time, to check that the criteria are met by the producer, but they are not carried out systematically for each product.

Thus, unless all the production and / or processing actions are carried out by the same entity, it is not possible to guarantee the traceability of interventions carried out on a foodstuff intended for food.

Subject and summary of the invention

The present invention aims to solve the various technical problems stated above. In particular, the present invention aims to propose a method making it possible to guarantee the traceability of actions carried out on foodstuffs, in particular foodstuffs. The present invention also provides a method allowing a seller or a consumer to know the different actions carried out on the product, and to be able to determine, if necessary, the regularity, by using for example photos or videos.

Thus, according to one aspect, a method of recording and storing data relating to foodstuffs intended for food, human or animal, having undergone at least two actions, such as packaging, production, is proposed. transport and / or processing, in which: - a first action is carried out and digital information is entered, for example written data, photos or videos, relating to said first action, - digital information is made available of said first action, then - a second action is carried out and digital information, for example written data, photos or videos, relating to said second action is entered, - the digital information of said first action is recovered, and - the digital information of said second action is added to the digital information of said first action, - the information is made available digital ons of said first and second actions.

We consider here that the actions (or the processes, or even the processing steps) carried out on the foodstuffs or when obtaining the foodstuffs, are the various interventions made by one or more people on the foodstuffs or during the of food. It can thus be here conditioning (characterized by its duration, its temperature, etc.), transport (characterized by its duration, its temperature, its vehicle, etc.), processing of foodstuffs, application of treatment on crops, food for animals, etc. This therefore concerns the various interventions, in particular human interventions, which have taken place on foodstuffs or during the preparation of foodstuffs, and which may have an impact on them.

Thus, thanks to the method according to the invention, it becomes possible to inform the consumer or a company marketing the commodity, on the various actions implemented during the manufacture or during the preparation of said commodity. In particular, the process makes it possible to enrich, with each action, the register of actions carried out in relation to the commodity, in order to gather all the information necessary for traceability therein. Thus, the register of the various actions carried out can be kept by a certifying body, or by an independent body. Alternatively, the register can be designed so that it can be enriched with each action, while guaranteeing that the preceding elements will not be modified. In addition, each contributor is responsible for the digital information that he makes available, whether it is digital information relating to his action on the commodity, or whether it is digital information relating to previous actions that he has previously obtained. Each stakeholder therefore ensures the reliability of the digital information that it collects, as well as that which it provides, to guarantee the traceability of the commodity it provides. A register is then obtained which reconstitutes the history of the product, and in particular the history of the actions taken to arrive at said product.

The principle used is thus similar to that implemented by the so-called “blockchain” processes (in English: blockchain): the digital information is reproduced redundantly, at the level of the various parties involved, in order to enrich and guarantee it. due to the repetition of these. The process then offers great security, without limiting the amount of information that can be guaranteed.

Preferably, the first action and / or the second action may comprise several sub-actions, and the digital information relating to the first action and / or to the second action includes digital information relating to each sub-action which is made available.

The process is thus not limited to the main actions carried out, but can also group auxiliary actions, the implementation of which can also impact the final quality of the commodity. The actions taken into account in the process are therefore not considered to be exhaustive, but can be supplemented later to take into account other parameters that may affect the foodstuffs.

Preferably, the digital information is made available to the public, for example via a site freely accessible on the internet, or is made available only to those in charge of the actions of said foodstuffs.

In order to allow each user or consumer to verify the information relating to the food they wish to consume, the digital information can be made available on a public server, requiring only an identification of the food for which the information is requested. , for example a lot number or QR code. Conversely, the details of digital information can be kept confidential by a set of stakeholders, and only global traceability information, easily understood by the user or the consumer, can be provided publicly.

Preferably, the provision of digital information comprises encryption of digital information, for example asymmetric encryption, and optionally the recovery of digital information comprises the recovery of a decryption key.

The encryption of the information makes it possible to guarantee that it has not been modified while making it available to supplement it with the subsequent information. Thus, asymmetric encryption allows a party to encrypt its data with its own encryption key, while third parties, having in their possession a decryption key different from the encryption key, can decrypt the encrypted information of said party . It is thus possible to share information in an encrypted manner, without having to share the encryption key. This guarantees that third parties, with their decryption key, will be able to access the information without being able to modify it.

Preferably, the encryption of the digital information comprises a hash function of the digital information prior to the encryption.

The hash function makes it possible to obtain a smaller representation of the digital information, while being specific to it. Thus, the hash function makes it possible to encrypt a smaller amount of information than the initial digital information, in particular in order to facilitate the transmission of such information. If the initial digital information were to be modified, even in a minimal way, it would lead, via the hash function, to a different representation. Thus, by encrypting the representation obtained by a hash function of the digital information, the content of the digital information is guaranteed while making it possible to have a smaller representation and therefore easier to transmit or store.

Preferably, the digital information is made available in a single data center, for example a server of a guaranteeing organization.

In order to facilitate the exchange of digital information, and its storage in a known manner, it is possible to provide a single data center configured to receive, record and make available digital information as and when it is produced. Alternatively, the digital information can be partially or totally, stored and shared by the various parties who can locally store the data and make it available to people wishing to recover it. The digital information can thus be recorded and made available by different parties, in a redundant manner.

The data center can be unique and / or specific.

Preferably, when adding the digital information of said second action, the digital information of said first action is not modified. More precisely, the digital information of said second action can be added to the encrypted digital information of said first action. It is not necessary to decrypt the digital information of said first action to add that of the second action. Once the digital information of the second action has been added, the set can be encrypted by the second party.

Preferably, the digital information made available remains accessible after its retrieval.

The digital information thus remains available individually throughout the enrichment process of the register linked to the manufacture or elaboration of the commodity. It is then possible for any party or for a third party who can access the digital information made available, and possibly the encryption keys, to check the digital information provided by each party.

Preferably, the digital information notably comprises biological or biochemical analysis data, in particular a biological or biochemical analysis comprising a pre-analytical phase and an analytical phase, and the data comprises a video recording of the pre-analytical phase and the result obtained. during the analytical phase.

Preferably, the pre-analytical phase includes the taking of a sample and possibly its preparation and / or packaging. These are the different steps implemented before the analytical phase and whose implementation can influence the result of the analysis.

Preferably, the analytical phase includes bringing the sample into contact with a reagent, revealing the result, and optionally preparing said reagent.

Preferably, the digital information also includes geolocation data. The geolocation data make it possible to know the place of performance of the action, and thus to know certain information concerning the implementation of this action.

Preferably, the digital information can comprise several geolocation data carried out several times during the action, in particular during the biological or biochemical analysis, for example by multiple acquisition of geolocation data by satellite (GPS) and / or by acquisition. displacement data obtained for example by an inertial unit. Thus, the displacement of the place of realization of the action can be carried out by successive geolocation measurements, or by the use of an inertial unit making it possible to know the various displacements carried out.

Preferably, the digital information can include local data, for example temperature, pressure, air humidity, altitude. Local data make it possible to know the conditions for implementing the action, in particular for biological or biochemical analysis. They can therefore contribute to the interpretation of the result of the action, and may therefore be necessary for traceability.

Preferably, the digital information also includes the time and / or the date.

Preferably, the digital information includes elements of identification of the operator performing the action, in particular biological or biochemical analysis, and / or elements of identification of the devices used for the implementation of the action , in particular biological or biochemical analysis.

Preferably, the digital information also includes elements for identifying the commodity.

According to another aspect, the invention also relates to the use of a device for capturing digital information, for example video or photos, and for transmitting dematerialized data, to implement the recording and storage method as as previously described.

Brief description of the drawings The invention and its advantages will be better understood on reading the detailed description of a particular embodiment, taken by way of non-limiting example and illustrated by the appended drawing in which the various successive stages are represented. of a method according to the invention.

Detailed description of the invention

The appended figure illustrates an example of implementation of a method 1 for recording and storing data relating to foodstuffs intended for food, according to the invention.

The method thus comprises a first step 2 of entering the digital information relating to a first action.

The first action can be a treatment, for example by Bordeaux mixture on a vineyard, or a vaccine on an animal intended for a slaughterhouse or on an animal supplying milk, or even a stage of packaging and / or transport.

The purpose of the digital information relating to the first action is to list and define the characteristics of the first action, in order to be able to deduce whether the rules in terms of regulations or in terms of labeling have been respected. The purpose of digital information is therefore to provide complete traceability of the foodstuff it relates to.

The digital information can thus be one or more photographs, one or more videos, or one or more documents making it possible to determine the characteristics of the action carried out.

According to method 1, the digital information thus entered is encrypted, for example asymmetrically, and made available. Preferably, the digital information is made available simultaneously or immediately after entry, and preferably automatically. This ensures that the information will not be selected, or even modified, by the person in charge of entering it, before the said digital information is made available.

Thus, once the photo or videos have been taken, these can be, in a second step 3, encrypted and sent directly to a server to allow them to be recovered by other people. This makes it difficult to select or filter the information that is transmitted. Furthermore, if modifications have to be made, these can be made later while keeping the initial information, in order to be able to possibly verify the initial information if necessary.

Optionally, and in order to limit the amount of information to be encrypted and to be transmitted, the digital information can be subjected beforehand to a hash function intended to reduce the size of the digital information while guaranteeing the content of said digital information. In particular, the hash function is intended to provide, from the digital information, a result of smaller size but which is specific to the digital information which it represents. Thus, if the digital information were to be changed, even in a minimal way, the result of the hash function, although of smaller size, would also be changed to reflect the fact that the initial digital information is no longer the same.

In a third step 4, digital information of a second action is entered. The second action can be performed by the same person as the first action, or by a different person.

We then recover, in a fourth step 5, the digital information of said first action, on the server, possibly with a decryption key. The decryption key is used to decrypt the encrypted digital information from the first action. However, such decryption is not necessary for the implementation of the remainder of method 1 according to the invention.

In particular, it is not necessary to decrypt the digital information of the first action to add that of the second action. Thus, during a fifth step 6, the digital information of the second action is added to the encrypted digital information of the first action.

Alternatively, the digital information of the first action can be decrypted for verification before adding the digital information of the second action. In this way, the digital information is verified with each addition of new digital information, which makes it possible to strengthen the traceability and the monitoring of the actions carried out on the same foodstuff.

Finally, in a sixth step 7, the digital information of the second action and that, encrypted or not, of the first action are encrypted and made available on the server.

The process can be continued thus, by enriching the register relating to the actions carried out on the foodstuff. The process can stop for example at the time of the marketing of the foodstuff, or of its consumption. All of the digital information made available can be accessible to the public, from an element identifying the commodity for which the information is desired, for example a batch number, a QR code, etc., or else may only be accessible by a limited number of people, for example people from a control body or a certification body.

Thus, thanks to the method according to the invention, it becomes possible to carry out traceability of all kinds of foodstuffs, throughout the production process, in order to guarantee the qualities and the respect of certain practices. In particular, the method according to the invention makes it possible to guarantee the traceability of the information made available which is difficult to falsify, while allowing the addition of additional information without constraint. The register thus formed by all of the digital information, then makes it possible to trace the history of the corresponding foodstuff, and makes it possible to determine whether the criteria of standards or labels have been respected.
