  • Patent number: 12010207
    Abstract: The present invention concerns a method for confidentially processing the kinematic data of a vehicle, in particular a method for classifying this data in order to determine the driving style of the vehicle while respecting the confidentiality of the data in question. The data is encrypted by the vehicle by means of a symmetric encryption algorithm using a secret key generated by the vehicle. This secret key is encrypted by the vehicle by means of a homomorphic asymmetric encryption algorithm by using the public key of a vehicle service provider. The data encrypted by means of the secret key, and the homomorphically encrypted secret key, are transmitted by the vehicle to an access point that transcrypts them and transmits the homomorphically encrypted data to a calculation platform. The platform performs the confidential processing operation in the homomorphic domain and transmits the homomorphically encrypted results to the server of the vehicle service provider.

  • Patent number: 11999613
    Abstract: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm and a cavity hermetically containing a deformable medium keeping a constant volume under the action of an external pressure change. The deformable diaphragm forms a wall of the cavity and has at least one free area so as to be elastically deformed. The electromechanical transducer is configured so that its movement depends on the change in the external pressure, and vice versa. The free area cooperates with an external member so that its deformation induces, or is induced by, a movement of the external member. Thus, the electromechanical microsystem is adapted to displace the external member or to detect a movement of this member, the electromechanical microsystem includes at least one pin, configured to bear on a peripheral portion of the free area so that a deformation of the free rea causes an inclination of the pin.
