Abstract: An exemplary method includes a proximity detection system that accesses information associated with a virtual location marker positioned in relation to a geographic area. The information defines a location-based field of view (“LFOV”) that extends directionally from the virtual location marker. The proximity detection system further tracks a location of a mobile computing device at the geographic area and determines, based on the information associated with the virtual location marker and the location of the mobile computing device, that the mobile computing device has entered the LFOV that extends directionally from the virtual location marker.

Abstract: A multi-scheme random selection of blockchain endorsers may preserve anonymity of nodes that participate in a blockchain network, and may assign each node an endorsement load that is proportionate to the utilization of the blockchain network by that node. Selection of one or more nodes to endorse data before recordation to the blockchain may include randomly selecting an active endorser selection scheme from a set of available endorser selection schemes, and randomly selecting one or more nodes as endorsers for the data based on the active endorser selection scheme. Each scheme may be derived based on the tracked utilization over different time scales. Exit criteria may determine when to switch the active endorser selection scheme. The exit criteria may be based on a number of times each node is selected as an endorser under the active endorser selection scheme, and utilization of the blockchain network by each node.

Abstract: Disclosed are systems and methods for anonymous, hands-free voice authentication to network resources. The framework can operate and provide a secure authenticated operating environment for any type of computerized platform, device and/or service while preserving anonymity of both the user and the user's login credentials. Once authenticated, the user is then permitted to perform desired operations, such as, CRUD (create, read, update, delete) operations. The disclosed framework operates in a three stage process, which involves single-sign on (SSO)/virtual private network (VPN) connectivity, which is then followed by a 4way voice matching user-device integrated “conversation” and a proof of work macro-micro problem verification step. The framework enables a user to login and access a system by responding to randomly verifiable requests output by the system dependent on the user's current surroundings.

Abstract: According to embodiments of the present invention, a method of additive manufacturing of an object using object material is provided. The method includes forming the object by processing some of the object material, and forming an object identifier by forming a pattern having at least one coded volume within an internal volume of the object, each of the at least one coded volume enclosing unprocessed object material. According to further embodiments of the present invention, an object manufactured using the method of additive manufacturing and a method of scanning an object identifier formed using the method of additive manufacturing are is also provided.
