Abstract: The invention relates to a method and a system for computer-assisted maintenance of a device to be maintained, comprising a storage in a first system, which storage is implemented progressively when in use an operating system comprising the device to be maintained, of operational data associated with the said operating system. For a maintenance processing method, which is to be implemented by the second system (8) by applying a processing algorithm (38) to a set of operational data, the maintenance system uses a homomorphic or partially homomorphic cryptosystem (28) to obtain a modified maintenance processing algorithm (40) which makes it possible to obtain an item of predictive or corrective maintenance information in encrypted form, from a set of protected operational data comprising a first subset of encrypted operational data ((D1)H) by a means of a cryptosystem encryption method (28), and a second subset of plain data (D2) from the said set of operational data.

Abstract: This method comprises: —integrating, into an initial item, a sensor allowing measurement of a physical quantity that varies as a function both of a characteristic of the initial item and of a morphological characteristic of the user, —acquiring measurements of this sensor, to obtain a measured value, —verifying that the measured value meets a predetermined set of conditions, —when the set of conditions is not met, transmitting signal indicating mismatch of the initial term with respect to the morphological characteristic of the user, and —when the set of conditions is met, inhibiting transmission of this mismatch signal.
