Method, apparatus and system for on-line generating random data

Abstract

The invention provides a method for generating random data on line. The method comprises the steps as follows: a client-side session id accessing a server is recorded; bitwise binary operation is carried out on all client-side session ids to generate a parameter d; original data is input; and the parameter d is used as a random seed to generate the random data. The random data is generated by recording the client-side session id accessing the server on line, generating the parameter d on line and using the parameter d as the random seed, thereby improving the efficiency and increasing the fairness and the satisfaction degree of the user. The invention also discloses a random data online generator and a random data online generating system. In the actual application, the random data online generating system can be a building opening quotation lot number remote live broadcasting system.

Description

technical field [0001] The invention relates to the field of network applications, in particular to a random data online generation method, device and system. Background technique [0002] In reality, due to the needs of applications, a limited number of data needs to be randomly selected from a large number of original data. Therefore, there are many random data generation systems, such as lottery lottery systems and real estate opening lottery systems. Assuming that the system is a real estate opening lottery system, the existing real estate opening lottery process is as follows: potential customers register at the sales office and receive a registration number. A limited number of random data is generated, the developer publishes the generated random number, and consumers who match the generated random number subscribe. [0003] Random numbers are widely used in software design, especially in the field of practice environment simulation and testing. In order to pursue a...

AI Technical Summary

Problems solved by technology

In order to pursue a truly random sequence, many primitive physical methods have been used to generate a uniformly distributed sequence that meets the accuracy within a certain range. The disadvantages are: slow speed, low efficiency, large storage space and non-reproducible, etc.

[0005] From the above description, we can know that the random seeds of the existing random data generation methods are related to the system clock on the server side, so the generated random data is easily affected by the server side, and the generated random data is not random enough.

In specific applications, such as in the real estate opening lottery system, the developer enters the registration numbers of all potential consumers on a single computer, and uses the system clock of the computer as a random seed to generate random data, because the random data is on a single computer. Generated, easily affected by a stand-alone server, the random data generated is not random enough, consumers often do not agree with the fairness of the generated random data, and the random data is not generated online, consumers cannot timely Check
