摘要

A method, system, and device for securely and deterministically selecting awinnerfor a raffle taking into account content from the raffle tickets of theraffle. Eachraffle ticket comprises entry data for obtaining an entry number such that theentrydata is strongly encrypted by the client computer for communication over thecomputer network to the server computer. Decrypting, at the server computer,theentry data. Obtaining a first output related to the raffle by computing afirstdeterministic mathematical function taking a first plurality of inputs,wherein thefirst plurality of inputs comprise the entry numbers. Selecting a winningraffle ticketby obtaining a second output related to the raffle by computing a seconddeterministic mathematical mapping function taking as a second input the firstoutput of the first mathematical function, wherein the second outputcorresponds tothe winning raffle ticket.
