Sasaki looks exactly like Kaneki. Only difference is that he's slightly older and has black amd white hair. Other than that his appearance hasn't changed much over the years. Ghouls also all have their own unique scents and Kaneki's/Sasaki's is particular.

Touka just has to look at and smell Sasaki to know it's Kaneki. Other things like crying over the coffee she made him and having an interest in books also tell her who he is.
