Abstract: Some implementations of the disclosure are directed to receiving, at an authentication server system, a distributed ledger address transmitted by a client device to identify itself during an authentication process for accessing a network, where the distributed ledger address corresponds to a distributed ledger network; transmitting an authentication challenge message from the authentication server to the client device; in response to transmitting the authentication challenge message from the authentication server to the client device, receiving at the authentication server, a response to the challenge message including a signature; and using at least the distributed ledger network to determine if the signature used to sign the response to the challenge message is associated with the distributed ledger address transmitted by the client device.

Abstract: Concepts and technologies are disclosed herein for providing augmented reality shopping displays. A processor can execute a shopping service. The processor can receive a request for display data. The processor can analyze shopping data to identify data sources, the shopping data can include user data associated with the requestor, and the data sources can include an offer source. The processor can obtain collected data from the data sources identified, the collected data including an offer. The processor can generate display data based upon the collected data and the shopping data, and provide the display data to a user device. The display data can identify the offer.

Abstract: Disclosed are some examples of database systems, methods, and computer program products for processing log files. In some implementations, log files can be accessed and identifiers can be generated for the data entries of the log files. The generated identifiers can be used to determine whether data entries in the log files are new, and therefore, should be extracted for analysis.

Abstract: The device for verifying parallelism of abutment teeth for dental appliance insertion provides a visual indicator for a dental practitioner for determining parallelism in a pair of abutment teeth. The device for verifying parallelism of abutment teeth for dental appliance insertion includes a housing having a top end, a bottom end, and longitudinally-extending slot formed therethrough. First and second rods are received within the longitudinally-extending slot and are longitudinally slidable therein, with each of the first and second rods extending laterally (i.e., perpendicular to the longitudinal direction) through the longitudinally-extending slot. First and second plates are respectively suspended from central portions of the first and second rods and are longitudinally slidable through an opening formed through the bottom end of the housing. First and second ratcheting mechanisms respectively limit rotational movement and rotational direction of the first and second plates with respect to the housing.
