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: 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: 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.
