You may recall back in December that Canon’s original data security system was compromised. The same company, Elcomsoft, has now shown that Nikon’s Image Authentication System is just as vulnerable. At first I wondered why they would do such a thing, but it’s very clear now that the purpose was to prove that these authentication systems are not bullet proof and therefore we should not completely trust every image we see. A good lesson to learn.
As a result, any photographic evidence submitted that was captured with an affected camera (as well as any future camera using the same signing key) should not be automatically taken as genuine just because it passes validation with Nikon Image Authentication Software. – Elcomsoft
