Abstract: A method comprises: receiving, by a user device, from a verifier device, a request for user data; retrieving a first cryptogram and a decryption key; sending and, to a server, the first cryptogram; retrieving a random and a second cryptogram generated using reference user authentication data concatenated with the random; sending, to the verifier device, the second cryptogram and the random; storing the reference random; sending, to the user device, the second cryptogram; decrypting the second cryptogram using the decryption key; extracting the reference user authentication data and the random; providing, the user device, with user authentication data; verifying that it matches the reference user authentication data; providing, the verifier device, with the random; verifying that it matches the reference random; and authenticating the user data.

Abstract: Provided is a method for facilitating the renewing of a digital identity document. It includes receiving a request for renewing a digital identity document; checking whether said digital identity document can be renewed, if the check result is positive, creating an up-to-date validity-related data item to be associated with said digital identity document and to be inspected by a verifier when the validity of said digital identity document must be assessed; and sending said up-to-date validity-related data item to a device of a user of said digital identity document so that a validity-related data item previously associated with said digital identity document can be replaced by said up-to-date validity-related data item at the user's side.

Abstract: A method for authenticating a device, comprising: sending, from a user device to a server, a data request; retrieving a predetermined encryption key; generating and at least a random and a cryptogram using the encryption key and the random; sending, to the or another user device, the cryptogram and the random, as a data request response; extracting, from the data request response, the random and storing, at least in a temporary manner, the reference random; sending, to at least the device, the cryptogram; decrypting the cryptogram using a predetermined decryption key and obtaining a random; sending, to the user device, the random; verifying whether the received random matches or not the reference random; and authenticating, only if yes, the device.

Abstract: Distractor and retractor systems and methods of using the same. A pedicle-based distractor assembly may include a base supporting a distraction rack, a pair of moveable arms coupled to the distraction rack, a connector at the end of each arm, each connector having a through-opening, and a pair of distractor elements each configured to attach to a pedicle screw. Each distractor element may be positioned through the through-opening in the respective connector. The distractor elements are modular such that different types of distractor elements, such as headless posts, pre-assembled posts, or minimally invasive towers, are interchangeable with the connectors. The assembly may also include a retractor assembly with a medial retractor blade for retracting soft tissue.

Abstract: Electronic voting including a registration authority server, an election authority server, and a voter-host computer connected to an electronic identity card associated with a voter casting a vote. The registration authority server computer and the secure electronic identity card establish a first cross-domain unlinkable pseudonym for the secure electronic identification token, the first cross-domain unlinkable pseudonym being unique to the electronic identity card and the registration authority. The registration authority writes a vote-eligibility attribute on the electronic identity card. The election authority server computer retrieves a second cross-domain unlinkable pseudonym and the vote-eligibility attribute from the electronic identity card, the second cross-domain unlinkable pseudonym being associated with the election authority, and writes an attribute on the electronic identity card indicative of receipt of a vote cast by the voter.

Abstract: The present invention relates to a security management system for performing a secure transmission of data from a token to a service provider server by means of an identity provider server, wherein said security management system comprises: —said identity provider server which is adapted to: —open with said token a secure messaging channel by means of a General Authentication Procedure using at least one certificate; —receive via said secure messaging channel from said token enciphered data; —transmit to said service provider server said enciphered data; —said service provider server which is adapted to: —receive from said identity provider server enciphered data of said token; —decipher said enciphered data to extract said data; —said token which is adapted to: —encipher data; and—transmit via said secure messaging channel to said identity provider server said enciphered data.

Abstract: Exemplary embodiments are directed to a diffuser assembly configured to be disposed in an extraction path of an extracting solvent in an extraction vessel. The diffuser assembly includes a housing configured to be disposed within the extraction vessel, the housing including an inner surface and an outer surface. The diffuser assembly includes an inlet structure disposed within the housing. The diffuser assembly includes an outlet structure disposed within the housing and spaced from the inlet structure to form a mixing chamber between the inlet structure and the outlet structure. The inlet structure and the outlet structure each have a porosity configured for passage of the extracting solvent therethrough. Passage of the extracting solvent through the inlet structure, the mixing chamber, and the outlet structure redistributes flow of the extracting solvent along the extraction path.

Abstract: The present disclosure relates to methodologies, systems, and devices for compressing CO2 for recycling within a CO2-based chromatography or extraction system. A bellows pump can receive CO2 in a gaseous state and can compress the CO2 into a liquid or partially liquid-vapor state using hydraulic compression. Once compressed, the liquid or liquid-vapor CO2 can be recycled within the CO2-based chromatography or extraction system.

Abstract: The present disclosure relates to methodologies, systems, and devices for collecting extract in a CO2-based extraction system. A diffuser can be used, attached to one end of an extraction tube, in order to depressurize the CO2 and extract mixture as it exits the diffuser and enters the extraction collection container. A splash guard can also be attached to the extraction tube in order to block any splashing of extract while CO2 is allowed to vent from the extraction collection container.

Abstract: The present disclosure relates to methodologies, systems, and devices for discretely collecting extracts from an extract collection container of a CO2-based extraction system. A removable liner can be placed within the extract collection container such that the extract is collected within the removable liner, which can be removed or collected at discrete times. The removable liner can be hung from an extract fluid inlet tube or attached to an internal sidewall of the extract collection container.
