Looking for an iOS app recommendation

I want to take photos of my airline cards, library cards, insurance cards, etc and store the images in an app. I am looking for an iOS app to do this. I have four requirements:

1. Can take a picture of cards from within the app, or import into the app from Camera Roll.

2. Can classify the images into categories via tags, folders or similar method.

3. Can password protect the app so that images cannot be viewed / accessed without the password

4. Can sync images via iCloud to my other iOS devices (I really don't want a 3rd party syncing option - I have too many of those already).

I've found a number of apps on the App Store that perform items 1-3 above, but haven't seen one that can do all four. I welcome any suggestions for a photo app, crafts app, business card app, etc, that meets my requirements. Suggestions welcome. Thx
