Method and apparatus for storing redeem code, and method and apparatus for verifying redeem code

摘要

Implementation manners of the present disclosure provide a method and an apparatus for storing a redeem code and a method and an apparatus for verifying a redeem code. The method for storing a redeem code includes: generating a random value, and determining an index of the random value according to an order in which the random value is generated; generating a number pair according to the random value and the index of the random value, mapping the number pair to a string, and generating a redeem code according to the string; and determining a storage location of the random value according to the index of the random value, and saving the random value at the determined storage location.

1. A method for storing a redeem code, the method comprising:
generating a random value, and determining an index of the random value according to an order in which the random value is generated; generating a number pair according to the random value and the index of the random value, mapping the number pair to a string, and generating a redeem code according to the string; and determining a storage location of the random value according to the index of the random value, and saving the random value at the determined storage location; wherein the generating a redeem code according to the string comprises: performing obfuscation processing on the string, to generate the redeem code; and wherein the method further comprises: determining an expected generation quantity of the redeem code, and determining a number of digits of the index according to the expected generation quantity of the redeem code; and determining a probability threshold value of cracking the redeem code, and determining the number of digits of the random value according to the probability threshold value of cracking the redeem code; and the generating a random value, and determining an index of the random value according to an order in which the random value is generated comprises: generating the random value according to the number of digits of the random value, and determining the index of the random value according to the order in which the random value is generated and the number of digits of the index.
