Definition from wiki, Hologram is a three-dimensional image formed by the interference of light beams from a laser or other coherent light source.

Generally holograms are used on product envelops to ensure authenticity of trademark/brand of the product. It's just a historical way used for many things like books, cloths etc, etc. But now, almost nobody is using them. Bar-code is more in fashion. It's really tough to find a product with hologram sticker on it in the market.

Captcha is used to authenticate human user & to avoid spam.

So, here I can't see any "(instead of capcha)" thing for hologram.

Next thing, Even if you want to implement "Hologram" in your app, I don't think you can implement real hologram effect on device.

One thing you can do is, you can detect device motion & virtually create hologram effect in your app.

This link might help you to implement Core Motion in iOS. Let me know if more info needed.
