I have a customer asking for a feature to do data scramble.

The need is change the production data to be used in another environments without the user know the original data.

e.g:
Give the person table:

CREATE TABLE person (
  id INT PRIMARY KEY,
  name VARCHAR(256) NOT NULL,
  age INT,
  height INT,
  weight DOUBLE
);

SELECT * FROM TABLE PERSON WHERE ID=1;

Result:
The name is from row with ID#15, the age is from row with ID#3, the height is from row with ID#5.

On this way the customer can work with consistent and natural data, but unreal.
