Summary:The invention relates to the technical field of identity authentication, and provides a biological characteristic data processing method and system based on random confusion and a storage medium. The method comprises the steps: obtaining a biological characteristic data source file; preprocessing the obtained biological characteristic data source file so as to randomly divide the biological characteristic data source file into n parts of biological characteristic segmentation data, wherein n is a random number; generating a confusion strategy based on the random number n, performing confusion recombination on the divided n parts of biological characteristic segmentation data based on the confusion strategy to generate a biological characteristic confusion file; and associatively storing the biological characteristic confusion file and the confusion strategy in a preset confusion database. According to the technical scheme provided by the invention, the problem that the user identity information is leaked due
