A term for providing irrelevant and hiding relevant information [closed]

For example, you're doing a research for a car to purchase. You get a list of cars with engine number, city where a car was assembled, and a color. What's missing is make, model and price.


Solution 1:

When it's done deliberately, it's obfuscation.

Solution 2:

The irrelevant information could be described as a smokescreen.
