METHOD, SYSTEM, AND DEVICE FOR SELECTING A WINNER OF A RAFFLE BASED ON CONTENT FROM RAFFLE TICKETS

摘要

A method, system, and device for securely and deterministically selecting a winner for a raffle taking into account content from the raffle tickets of the raffle. Each raffle ticket comprises entry data for obtaining an entry number such that the entry data is strongly encrypted by the client computer for communication over the computer network to the server computer. Decrypting, at the server computer, the entry data. Obtaining a first output related to the raffle by computing a first deterministic mathematical function taking a first plurality of inputs, wherein the first plurality of inputs comprise the entry numbers. Selecting a winning raffle ticket by obtaining a second output related to the raffle by computing a second deterministic mathematical mapping function taking as a second input the first output of the first mathematical function, wherein the second output corresponds to the winning raffle ticket.
