Yes, this is you.
I wonder in what context you want to use this sentence.
And always, it's important to know the relationship between speakers.
1. between families or friends// or to someone under your age
응, 이거 너야. / 어, 이게 너야.
2. in formal situations
네, 이게 본인이세요./
it's better to know how you call the person.
