Encapsulation refers to the bundling of data with the methods that operate on that data. 

Hiding data is not the full extent of information hiding. Primary criteria for system modularization should concern the hiding of critical design decisions, hiding "difficult design decisions or design decisions which are likely to change." Hiding information in that manner isolates clients from requiring intimate knowledge of the design to use a module, and from the effects of changing those decisions.
