Abstract
Location data from one or more geolocation engines such as GPS, a system that determines location from relative signal strengths or transit times, etc., within and/or connected to a device, such as a mobile phone, vehicle, movable electronic device, computer, etc., is included in a digital record that submitted to obtain a digital signature such that the presence of the device at the particular location can later be proven. The digital record may include data that encodes a message, as well as other parameters such as time. The digital signature encodes recomputation parameters of a hash tree signature infrastructure to a highest level value, a function of which is submitted as a transaction in a blockchain.
