  • Publication number: 20220231841
    Abstract: A method for accessing a private key is provided. The method includes storing, by a first device, the private key and an associated public key, generating an access token, sending to a second device, the access token, sending, to a first server, an address relating to a decentralized identifier and the access token, sending, by the first server, to a ledger, a request for getting a decentralized identifier along with the decentralized identifier address. By way of the method a solution is provided for accessing, by a first server to be accessed from a second device, based on a decentralized identifier readable from a ledger, a second server, as a proxy to a first device. It allows for authenticating a first device to a first server while keeping the private key only at the first device side (and not at the second device side).

  • Patent number: 10996708
    Abstract: This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base Tbase (i) synchronized with card i, the method comprising the steps of: receiving at a time TS a dynamic card verification dCVV code value generated by card i; providing a set of at least two dCVV code corresponding to two successive dCVV time periods; if the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase(i) of the card; updating time base Tbase(i) by addition of a time drift correction equal to the minimum possible time drift Min_td.

  • Patent number: 9889419
    Abstract: A method for managing the charging of a space with solid particles, comprising: modelling an expected charging profile over a charging duration, during the charging, receiving, from at least one sensor, measured values of a parameter indicative of the height of a bed of solid particles charged into the space, determining filtered values of the parameter indicative of the height from the measured values received and from the modelled charging profile, and transmitting the filtered values to control the charging with solid particles.

  • Patent number: 5211955
    Abstract: A pharmaceutical composition containing an hydrophilic aminoglucoside antibiotic coupled with an organic acid. The coupled aminoglucoside antibiotic and organic acid are encapsulated in a liposome. The composition of the invention is self-regulating in that it liberates the active compound in inverse proportion to the concentration of the compound in the external medium. As a result, the composition serves as a long-acting antibiotic while avoiding the release of a toxic or ineffective dose of the antibiotic into the subject.
