Random number acquisition method and system for lottery industry

Abstract

The invention provides a random number acquisition method and system for the lottery industry. The random number acquisition method comprises the steps: obtaining an initial random number L and a random number seed; calling a QT library to set a random number seed function, and parameterizing the random number seeds to obtain an initial random number sequence; calling a QT library random functionfor L times to obtain a first residual random number sequence; responding to the random number request, selecting a preset mode, calling a QT library random function for a certain number of times, andobtaining a final random number; and when a next random number request is received, selecting another preset mode based on the residual random number sequence, and calling the QT library random function for a certain number of times to obtain a new residual random number sequence and a corresponding final random number. According to the random number acquisition method and system, different random number seeds can be set according to different sales terminals, and multiple random factors are introduced in the random number obtaining process, and the service requirements of machine selection numbers and other functional scenes needing random numbers are met, and the use experience of random betting of lottery buyers is improved.

Description

technical field [0001] The invention relates to the technical field of random number generation, in particular to a random number acquisition method and system used in the lottery industry. Background technique [0002] Currently, random numbers are widely used in various data encryption algorithms, such as RSA (Rivest, Shamir, Adleman), Digital Signature Algorithm (DSA), and Diffie-Hellman. A random number generator may be a computing device designed to generate a series of numbers and / or symbols lacking any recognizable pattern. In the case of lotteries, prize sales (such as flash sales), the fairness of the results depends almost directly on how random the random sequence is. Therefore, the randomness of the random sequence must meet very strict requirements. [0003] Nowadays, the lottery terminal is provided with a "machine selection" button, through which the betting numbers can be randomly generated for lottery players to bet. In the existing machine selection meth...

Problems solved by technology

In the existing machine selection method, the random number method adopted is generally as follows: the sales terminal starts calculation and sets the random number seed, calls the QT library random function several times; when the application of the sales terminal needs to obtain random numbers (such as the user needs the When selecting betting numbers, you need to use the application to obtain random numbers), call the QT library random function, and get the required random numbers; in this way, the random number seed setting method is single, the random factors are few, and the randomness of the random numbers needs to be improved
