In what way? That's the question here, and it's not clear what the answer is. As described, the spell only affects the four spells listed, and the value seems very limited. If you've obscured the item you've stolen, and someone seeking it looks at you via Arcane Eye, Clairvoyance, Scry, or Greater Scry, they won't see it on your person. Well, OK--but if the searchers are spying on you this way, you're obviously a suspect, and they could just as well follow up (once the divination pins down your location) with direct observation, against which the spell will be useless.
