Thoraiya DyerInvisibility Cloak: A Futuristic Way to Protect Our Privacy?

What is the invisibility cloak? For the non-believer, it will be pretty hard to explain the concept of warping space, creating material that does not exist in nature, and testing "invisibility" that operate within the laws of physics. But warping space has become possible, thanks to knowledge of blackholes. "Metamaterials" have now been discovered and found useable, especially in constructing what is now called the invisibility cloak, a real one at that.
We can call it optical illusion but it's more than that. The creation of void, where light is unable to pass through, is what makes the metamaterial used in the "cloak" invisible. Today, there are still loopholes to this concept.
With the help of nanotechnology and latest advancements in science, it's possible to recreate complex metamaterials to commercialize the invisible cloak. But first, these metamaterials would have to face serious trouble when interacting with the different wavelengths of light.
In other words, there will be areas in the cloak where light can still pass through, rendering some areas visible, and others not. And that's just scratching the surface.
(Though not perfect, the invisibility cloak has passed the test and is likely to futher increase sales of Harry Potter items. I was hoping scientists were able to make my flying dream come true with Aladdin's carpet. But we're talking biometrics here, so I won't digress.)
Conclusion: The invisibility cloak is a good way to mitigate the burdensome idea of loss of privacy, but it still doesn't let me PASS THROUGH doors to gain access to the office. The cameras won't detect me, but the fingerprint scanner needs to be dealt with.
The invisibility cloak is a more ambitious attempt, compared to the electric plaids and smart color-changing fabrics, to conceal our presence and thus protect our privacy. But I've yet to "see" where the salesclerks will hang it in the Clothes section of the department store!
