Problems solved by technology

[0004] However, the above-mentioned lottery numbers are generated by the lottery organizer, and the randomness of the lottery is doubtful. It is possible that the lottery organizer tampers with the lottery numbers. For example, the lottery organizer knows the lottery numbers to be drawn and modifies, increases or decreases Odds of winning certain lottery numbers
Therefore, it is difficult for the existing lottery mechanism to prove itself fair and just
In addition, existing users need to participate in the number lottery with their real names, and the user's private information may be known by other people, and thus be used illegally, which will bring some adverse effects to users

Abstract

The invention provides a target user determination method and device, equipment and a storage medium, and the method comprises the steps: uploading a random number corresponding to a to-be-participated user to a blockchain to determine a lottery number, determining a to-be-extracted object based on the data stored in the blockchain and a plurality of signature terminals, and based on the lottery number, determining a target user corresponding to the to-be-extracted object, and sending a notification message to the target user. Wherein the security of the to-be-extracted object is ensured by the blockchain and the plurality of signature terminals, so that any party, such as a shaking organizer, cannot tamper the to-be-extracted object, thereby ensuring the accuracy of a target user determined subsequently on the basis of the to-be-extracted object, improving the fairness and fairness in the user extraction process. Furthermore, according to the method of the invention, the real information of the to-be-participated user does not need to be known, and only the random number corresponding to the to-be-participated user needs to be known, thereby protecting the user privacy informationand preventing the user privacy information from being illegally used.

Description

technical field [0001] The present application relates to data processing technology, and in particular to a target user determination method, device, equipment and storage medium. Background technique [0002] With the continuous development of economy and technology, various lottery technologies and applications have widely affected people's life and work, such as lottery to determine the winning unit, lottery to arrange examination seats, lottery to determine license plate qualifications, lottery to allocate affordable housing, etc. [0003] In related technologies, the lottery process is usually: the user obtains a lottery number with his real name, and the lottery number is generated by the lottery organizer using a random value algorithm. The user who matches the winning number will be the winning user. [0004] However, the above-mentioned lottery numbers are generated by the lottery organizer, and the randomness of the lottery is doubtful. It is possible that the lo...
