Abstract: Disclosed herein are methods, systems, and processes for distributed logging for securing non-repudiable transactions. Credentials, request information, response information, and action items generated and received by a requesting computing system and a responding computing system, and transmitted between the requesting computing system and the responding computing system are separately recorded and stored in a requestor log maintained by the requesting computing system and in a responder log maintained by the responding computing system.

Abstract: A method, system, and apparatus, including a program encoded on computer-readable medium, for displaying health status information on a display of a mobile device and detecting encoded data on the mobile device using an image sensor. The encoded data includes a reference to a digital token previously stored in a distributed ledger to record at least one health-related event associated with the displayed health status information. A serialized representation of the detected encoded data is transmitted to a server system. The server system is adapted to retrieve corresponding health status information and authenticate the retrieved health status information based on the digital token. A communication is received from the server system providing verification of the health status information.
