Generalized derivations on C*-algebras determined by actions at orthogonal elements

Let A be a C*-algebra, and let δ, τ : A → A** be a continuous linear map. We assume that δ, τ acts like a generalized derivation at orthogonal elements for several types of orthogonality conditions such as ab = ۰, ab*= ۰, and a*b = ۰. In each case, we characterize the precise form of δ and τ.
