Abstract: Provided are a kiosk and method for anonymously relaying content from a public kiosk to a portable electronic device. The method includes receiving user input corresponding to content requested by a user, and accessing information stored by a non-transitory computer-readable medium. With at least one computer processor, an output comprising a computer-readable code encoding the content requested by the user is generated, and displayed using a computer display device operatively connected to the at least one computer processor. The computer-readable code, as a result of being captured by an optical imaging device provided to the portable electronic device, is interpreted to cause the portable electronic device to execute computer-executable instructions stored by the portable electronic device to perform an operation corresponding to the computer-readable code.

Abstract: A decision tree processing system comprises non-transitory data storage configured to store a target data stream and a hardware processor in communication with the non-transitory data storage. The hardware processor can be programmed to access the target data stream, apply a decision tree to at least a portion of the target data stream, and generate a predicted outcome based at least partly on the applied decision tree. The decision tree can comprise a question set that is applied to the target data stream to generate a set of answers that are used at least partly to generate the predicted outcome. In various implementations, the decision tree processing system can be applied to geographic information services, prescription medication prior authorizations, or the Internet of Things.
