It is essential to have efficient, simple, quick and transportable tools for reliably identifying bacteria that are multiresistant to antibiotics, more specifically extended spectrum β-lactamase (ESBL)-producing Enterobacteriaceae, which are the most widespread among Enterobacteriaceae. The present invention meets this requirement through its ease of use and its speed. The invention is based on detecting the enzyme activity of β-lactam hydrolysis using an antibody capable of discriminating between the intact form of the β-lactam ring of a β-lactam and its hydrolysis product. This antibody can be used in kits and methods enabling for rapidly detecting (in less than one hour), without using expensive equipment (a small strip visible to the naked eye), the presence of bacteria producing penicillin-type, plasmid-mediated or hyper-produced AmpC enzymes, of ESBL or carbapenemase from colonies or in a sample.

This server compares the first and second biometric models in the homomorphic domain and supplies the homomorphically-encrypted result of the comparison to the access control operator. The latter grants or denies access to the user according to the result of the comparison, after having decrypted it.

A method for confidentially querying the presence of a record in a database hosted by a server, the records being stored in the database in the form of digital footprints obtained by hashing a record by a public hash function. The footprints are masked by a stream cipher using a symmetric key of a first user. The first user may grant a second user authorisation to query the database by transmitting the inverse masks of various rows, encrypted by the public key of an additive homomorphic cryptosystem of the second user. The rows of the database are unmasked in the homomorphic domain and the second user transmits an encrypted request to query the base according to a PIR protocol. The second user can decrypt the response from the server using the private key of their homomorphic cryptosystem and determine whether the footprint sought is present in the response thus decrypted.

METHOD FOR GENERATING AN EVIDENCE OF THE TIME ELAPSED BETWEEN EVENTS IN AN ASYNCHRONOUS NODE NETWORK

Inventeur(s)
Hennebert, Christine
Paulin, Dylan
Abrégé
A method for generating an evidence of the time elapsed between two successive events occurring within a node of an asynchronous network, for example between two transactions emitted by such a node intended to a distributed register (ledger). The node is provided with an embedded system comprising a TPM module generating a control clock, a system clock within a TEE environment and a precision clock. The node verifies the coherence of the clocks by comparing the measurements of the time elapsed between two successive transactions, the measurements having been performed by means of the different clocks. In case of coherence of the measurements, the node emits a transaction proving the elapsed time intended to the distributed register. A verifier node may verify this evidence and certifies that the evidence is verified by emitting a validation transaction to the distributed register.

Abrégé
The invention relates to an electromechanical microsystem comprising an electromechanical transducer, a deformable membrane and a cavity hermetically containing a deformable medium, preserving a constant volume under the action of an external pressure change. The deformable membrane forms a wall of the cavity and has at least one free zone being deformed. The electromechanical transducer is configured, such that its movement is a function of said external pressure change, and conversely. The free zone engages with an external member, such that its deformation induces, or is induced by, a movement of the external member. The electromechanical microsystem is thus capable of moving the external member or of capturing a movement of this member.

METHOD FOR COMPRESSIVE MEASUREMENT OF THE STATISTICAL DISTRIBUTION OF A PHYSICAL QUANTITY

Inventeur(s)
Guicquero, William
Poisson, Valentin
Abrégé
A method and a device for measuring the statistical distribution of a physical quantity by a sensor. At each observation of the physical quantity, the sensor provides, in the form of a binary vector, a quantised value of this quantity. Afterwards, this binary vector is projected onto a measurement space with a smaller dimension than the number of quantisation levels in order to provide a vector representative of the quantised value. The measurement vector of the histogram is updated on the fly by adding thereto the vector representative of the quantised value. Afterwards, this measurement vector may be used as an input variable of a neural network trained beforehand to predict a target variable dependent on the statistical distribution of the physical quantity.
