Abstract

A method for issuing a digital residence certificate using a module associated with a counter. Data from the counter are continuously monitored, whereby the data are read and a consistency test is performed on the basis of a predetermined criterion. In addition, after receiving a residence certificate request, a decision is made as to whether or not the request should be fulfilled, based on the results of the continuous data monitoring.

Claims

1. A method implemented by means of computer resources of a module for a conditional issue of a digital residence certificate, for conditionally issuing a digital residence certificate, a residence having at least one meter measuring the consumption of fluid or electricity supplying the residence, the meter being designed to recurrently send data corresponding to a current state of the meter, the method comprising the steps of:

continuous monitoring of said data with, for each new transmission of data, a reading of the data sent by said meter and a consistency test on the data read, on the basis of at least one predetermined criterion, and

after receiving a residence certificate request from at least one remote entity, a decision is made as to whether or not to fulfil the request, based on a result of said continuous data monitoring,

storing of reference data for initialization of the continuous monitoring prior to the continuous monitoring,

wherein the reference data and the data in each transmission include at least identification data for the meter and said predetermined criterion includes at least one verification of a meter identifier,

wherein said reference data and the data in each transmission also contains a resident profile, and the predetermined criterion also contains verification of consistency of the resident profile, and

wherein in the event of non-fulfilment of the consistency test, applying a lasting block to any future residence certificate requests;

wherein in the event of non-fulfilment of the consistency test relating to the resident profile, applying said lasting block such that it can be lifted by the resident;

wherein in the event of non-fulfilment of the consistency test relating to a negative verification of the meter identifier, applying said lasting block such that it can only be lifted by an external authority.

2. The method according to claim 1, wherein the data sent by the meter can change from one transmission to the next and the method comprises:

a) reading of the data in a first transmission, followed by storage of said data,

b) reading of the data in a second transmission, which follows the first transmission, with a view to performing said consistency test between the data in the first and second transmissions,

and repetition of steps a) and b) based on the recurrence of transmissions of data sent by the meter.

3. The method according to claim 2, wherein said data comprise at least one consumption value, and the predetermined criterion comprises verification of a consistent increase in consumption, from one transmission to the next.

4. The method according to claim 1, wherein said data also comprise status information representative of the integrity of the meter,

and the predetermined criterion also comprises verification of the integrity of the meter.

5. The method according to claim 1, wherein the data originating from the meter are sent in recurrent frames and in that the consistency test relates to the data in a current frame compared with the data in a preceding frame.

6. The method according to claim 5, wherein the predetermined criterion also comprises verification of a format of frames sent by the meter.

11. A method of performing a secure transaction requiring a digital residence certificate using the method of claim 1.

15. A non-transitory computer readable storage medium, having stored thereon a computer program comprising program instructions, the computer program being loadable into a data-processing unit and adapted to cause the data-processing unit to carry out the steps of claim 1 when the computer program is run by the data-processing device.

7. A module for conditionally issuing a digital residence certificate,

said module comprising:

a first communication interface with at least one meter measuring fluid or electricity supplying a residence, in order to recurrently receive from the meter data corresponding to a current state of the meter,

a second communication interface with at least one remote entity to receive residence certificate requests,

storage elements to store identification data sent by said meter and reference data, and a processor for;

comparing current data received from the first interface with data previously stored by the storage elements in order to verify consistency between said current data and the data previously stored, on the basis of at least one predetermined criterion,

following receipt by the second interface of a residence certificate request (REQ), cooperating with said second interface to fulfil or not to fulfil the request, on the basis of said verification of consistency,

wherein a resident profile is contained in said current data received from the first interface, and the predetermined criterion also contains verification of consistency of the resident profile according to said reference data, and

wherein said predetermined criterion includes at least one verification of a meter identifier according to said identification data and said reference data,

in the event of non-fulfilment of the verification of consistency, applying a lasting block to any future residence certificate requests, wherein

in the event of non-fulfilment of the verification of consistency relating to the resident profile, applying said lasting block such that it can be lifted by the resident, whereas

in the event of a negative verification of the meter identifier, applying said lasting block such that it can only be lifted by an external authority.

8. The module according to claim 7, wherein the first communication interface is connected to the meter by a wired link.

9. The module according to claim 7, wherein the first communication interface is connected to the meter by a short-range wireless link.

10. The module according to claim 7, comprising a protective casing and a device to detect opening of the casing.

12. A data processing system for a secure transaction requiring a digital residence certificate, the system comprising:

an entity requiring a digital residence certificate,

a meter for measuring fluid or electricity in a residence, comprising a module for conditionally issuing a digital residence certificate according to claim 7.

13. The system according to claim 12, wherein the module is integrated into the meter.

14. The system according to claim 12, wherein the entity is a remote server connected to the module by a wide area network.
