1. the method for a data perturbation comprises:

  • First data structure of expecting its upset is operated, and wherein data perturbation comprises that the pseudo-random data value of the distribution that can reflect data value in the data structure that generates with determinacy ground comes the data value in the replacement data structure;

    Part based on described first data structure is created serial data, and described first data structure comprises the data value of delegation or multirow and row or multiple row;

    Based on described serial data, determinacy ground generates second data structure from least one the 3rd data structure,(1) wherein said second and at least one the 3rd data structure comprise the data value of delegation or multirow and row or multiple row, and(2) described second and row of at least one the 3rd data structure or each row in the multiple row all corresponding to the described row or the data value type of multiple row in described first data structure;

    AndReplace described first data structure with described second data structure.
