Abstract: A multi-user collaboration system, and a method of providing the same are disclosed. The method involves creating a workspace to which a plurality of digital materials can be shared by one or more internal users; receiving, from an internal user of the one or more internal users, an external collaboration request to collaborate with an external user type; in response to receiving the external collaboration request: creating a sub-workspace in association with the workspace for the external user type; and assigning a sub-workspace user group to the sub-workspace; and displaying a set of feedback on the one or more digital materials to a user. The sub-workspace is accessible by an external user associated with the external user type to provide a sub-workspace feedback in respect of one or more digital materials of the plurality of digital materials shared to the sub-workspace.

Abstract: A key updater for a first party operating on a network generates a mutually distilled key for communication between the first party and a second party. The key updater determines a set of verifying parties operating on the network needed to authenticate the mutually distilled key, wherein each verifying party of the set of verifying parties operates on the network. The key updater iteratively executes a key equivalency test for each verifying party in the set of verifying parties to determine a nonce sum until the key equivalency test has been executed for each of the verifying parties in the set of verifying parties or until it is determined that at least one node on the network has been compromised. The key updater generates a final key for communication between the first party and the second party based on the nonce sum and the mutually distilled key.

Abstract: The article of footwear for grounding the human body to earth includes an upper portion; a sole having an outer sole face distal from a user and an inner sole face proximate to the user; one or more electrically conductive portions which extend through the sole from the outer sole face to the inner sole face; and an electrically conductive layer which extends over a portion of the inner sole face and being configured to make conductive contact with the foot of the human body. The sole includes a blade portion.
