[Retracted] An Automated Data Desensitisation System Based on the Middle Platform Table 9 Sensitive data desensitisation intensity grading.

1 For random numerical type sensitive data, because there was no coding structure limit, the deformation effects were mainly affected by the algorithm. So, the default desensitisation intensity was equal to the configured value.
