We demonstrate the viability of baryogenesis from light scalar decays {\it {after}} the electroweak phase transition. A {\it {hidden}} fourth generation of quarks and leptons is used to introduce extra CP violations to the standard model. A simple extension of the standard model is constructed in which cosmic strings are formed at the electroweak phase transition. These strings decay into colored scalars which themselves decay into baryons and leptons. Baryogenesis occurs in the fourth generation but the baryon number is later transported to the visible generations. This mechanism of {\it {indirect}} baryogenesis allows us to satisfy experimental limits on the proton's lifetime while still having perturbative baryon number violation at low energies.
