I am looking for a schema that select only sensitive data from big data.
You are asking a very difficult question. Once sensitive attributes are mixed in data collected, it's difficult to extract or filter it.
Usually the aim is to protect people against the unauthorised use of their sensitive attributes, hence it's the opposite of what you are asking.
Are you sure you need the sensitive attributes in isolation?
It's risky stuff if it gets used by the wrong people, potentially leading to discrimination and other unfair treatment.
Please explain your objectives in more details
Dear Lujain
It is a pre-processing approach, first decide the goal then decide what attributes are the most sensitive for that goal.
You may use a new class attribute that represents the (goal), then using a decision tree algorithm you may find the most sensitive attributes for that goal, the higher the attribute in the decision tree the most sensitive it is, and all neglected attributes are the insinsitive ones.
best regards
