Desensitisation algorithms and weights.

Algorithm	Description	Example	Weight
Mask	Use symbol “” to replace parts of the data, with the data length unchanged.	13088886666 -> 130	1, 0, 1
Floor	Take an integer	—	0, 0, 0
Hashing	Map data into a fixed-length string	13088886666 -> abcdef	0, 0, 1
Truncation	Cut parts of the data	13088886666 -> 130	0, 0, 1
Shift	Add an constant offset	13088886666 -> 13088886670	1, 1, 0
Synthesis	Simulate new data to replace the original data	13088886666 -> 13011007788	1, 1, 1
Rearrange	Sort a column of values upside-down	—	0, 0, 0
