Description
Technical Field
The invention relates to the field of business support systems, in particular to an anti-cheating lottery method and device for online general lottery activities.
Background
Random numbers are a statistical concept and are the result of random trials. There are many different ways to generate random numbers, which are referred to as random number generators. The random number generator is a device for generating random numbers by using physical phenomena, such as extracting random numbers by methods of thermal noise, electrical noise, single photon counting of a discrete quantum source, and the like; the random number can also be generated by using a computer algorithm, a random seed is required to be input into the random algorithm, and the random number is obtained through a determined algorithm.
In a conventional lottery process, as shown in fig. 1, the whole lottery process is completely implemented and controlled by the server application system, including the lottery algorithm and the generation of random number seeds related to business rules, there may be the following cheating methods (or risks):
firstly, generating through a lottery algorithm, and directly writing a lottery result;
secondly, through a lottery drawing algorithm, whether a random number is used for generating a lottery drawing result cannot be determined;
thirdly, if the supplier is required to store random numbers used by the lottery for auditing, but cannot determine that a plurality of random numbers are obtained for obtaining a desired lottery result in one lottery for selecting the desired lottery result; it is also possible to look for a random number that can generate a target lottery result in advance, and to use the random number directly at the time of access by a designated user.
Analyzing the above problems, it can be found that the traditional scheme causes the design of the vulnerability:
firstly, the generation of two key factors, namely a lottery algorithm and a random number seed, is realized and controlled by the application of a service provider application system, and the version cannot be controlled;
secondly, seeds are generated by adopting a random function of a development framework, and no trace can be left in the process of calling the function;
and thirdly, the number of seeds used in one lottery drawing process cannot be limited, a desired result can be obtained by obtaining the seeds for multiple times, and the significance of the seeds is lost.
Therefore, the common lottery drawing scheme only draws out lottery items meeting the requirements according to business requirements, cannot judge whether the lottery drawing result is subjected to human intervention, and cannot backtrack and audit the lottery drawing process. Therefore, how to realize backtracking and auditability of lottery activities and effectively discriminate whether lottery data is falsified, so that the lottery process is random, transparent and self-testable, and the improvement of the client confidence is a problem to be solved urgently at present.
