Information hiding is abstraction or encapsulation?

The title says it all, I am bit confused as I was asked a question that Information handling in term of OOP is abstraction or encapsulation? I opted for abstraction but still I am confused because in encapsulation we also hide the fields and in abstraction we hide the details. Any help in this regard

Here is a nice answer that I think it clears the confusion

Encapsulation has two faces; data abstraction and information hiding. Data abstraction is a type seen from the outside. Information hiding is a type seen from the inside.

  • Abstraction focuses on the outside view of an object (i.e. the interface)
  • Encapsulation (information hiding ) prevents clients from seeing its inside view, where the behavior of the abstraction is implemented

Encapsulation = Hiding the Complexities / information

Abstraction = A (somewhat) defined way to handle complexities, using encapsulation

Abstraction generally hides information, while Encapsulation separates the changeable data from the unchanged one. In this way, Encapsulation helps to achieve the Open Closed Principle.

It may help if you think of encapsulation as one of the tools used to create abstraction. See the wikipedia entry for encapsulation here http://en.wikipedia.org/wiki/Encapsulation_(object-oriented_programming)
