Abstract: Let be a prime ring with involution. Using work of V. K. Kharchenko it is shown that any generalized identity for involving derivations of and the involution of is a consequence of the generalized identities with involution which satisfies. In obtaining this result, a generalization, to rings satisfying a GPI, of the classical theorem characterizing inner derivations of finite-dimensional simple algebras is required. Consequences of the main theorem are that in characteristic zero no outer derivation of can act algebraically on the set of symmetric elements of , and if the images of the set of symmetric elements under the derivations of satisfy a polynomial relation, then must satisfy a generalized polynomial identity.
