The process of sweeping private keys involves a transaction in the blockchain.
I think what you meant was "importing" private keys.
But all in all, one time exposure of your paper wallet's private key means that you intended to spend its balance,
so there is no need for such security measure unless the wallet you're using is unsecured too.
No it is not impossible. The scanning and encryption of the private key is done offline, to protect it from the above mentioned dangers. Nobody can visually record or snoop your session, if this is done offline.
The App will have to contain some software to convert the QR Code to text

OP said that he wants to automatically sweep it as soon as he goes online, while having all the data encrypted, and I think the following program should work.
First, we need a digital camera to take a photo of QR code, then you connect it via USB to an offline machine, and decode the QR code from a photo to get the private key. Then you insert the address you want to sweep to, and the app creates a signed transaction with paper wallet's address as an input. Then you can transfer this signed transaction via USB or by scanning it's QR code on your phone, check that it is correct by some other software (Core, Electrum, etc.) and broadcast it.
But I'm not sure if this app is needed - it can be useful if someone is dealing with huge amounts of paper wallets, but if it's one-time only, then it's not a problem to do everything I've described step-by-step. Maybe it can be implemented as a feature in some wallet that already has a good cold storage functionality, like Electrum or Armory.
The App will reduce the risk in doing this ONLINE. You cannot have a situation where you stored coins securely for years in a paper wallet and the moment you go online to sweep it, then it is gone.
Every time I have to sweep paper wallets, I get that tightness in my ass, because you never know who is looking over your shoulder.
My long-term strategy for cold storage require me to have multiple paper wallets with small quantities. I do not want to store all my eggs in one paper wallet and every time I want to sell, I have to sweep all my coins and expose my whole hoard/private key. It just make sense to have multiple paper wallets, if you want to store bitcoins for a long time, but sometimes you have a need to use some and then you only have to sweep 1 or 2.

Can the government of any major country step in and do the unlikely?

One potential solution is to use Chipmixer, since there is no fee and you receive the private keys to your coins (so you can decide to set a low fee when sending your coins elsewhere).
It's possible that an entity would be able to attempt blockchain analysis to link together different addresses and wallets that you own, but it's not likely unless you either have a large amount of money; are buying something illegal; or someone has a personal vendetta against you.

Only on ViaBTC and maybe a couple of other small Chinese exchanges. These are very illiquid futures markets, and easily manipulated. I wouldn't put too much weight on the current prices.
After the fork, if/when we see markets open on the major exchanges like Bitfinex, things could get interesting. Everyone expects everyone else to dump their BCC. If it's anything like the ETH/ETC debacle, it won't turn out as everyone expects.

So far, the best investment I can recommend is the crypto market, it's getting bigger and its still young at the moment but the development is getting better so we can expect the increase of value overtime.
According to TAT the order is from April however the wording clearly says plans of purchasing does that mean that some units have been ordered already.
PHM also has plans of purchasing 2 ASICS from BFL
Can I propose a shareholder motion to not order from BFL currently based on past history but to look at alternatives or is that too soon to propose a motion
Ordering now will in my opinion be a bad idea for investors right from the start due to the backlog and I would not want to have investors having an orderbook set for now.

To the questions
PHM will mine alt-coins, including, but not limited to, Litecoin, Terracoin, Freicoin and any currently profitable crypto-currency available. Our hashing power will be aimed at different coins depending on each coin’s potential profitability. These coins will be sold at market to maximize their value and convert them into Bitcoin for dividend payment. Funds raised will go towards the expansion of our mining operation.
Shareholders own all PHM mining equipment. Currently, PHM is GPU-mining Litecoins at approximately 2.4Mh/s. We have an established dedicated mining room, which is properly temperature-controlled and secured.
How is potential profitability deduced and can we see the units
Buyback Rights
The issuer has the right to buy back shares at any time at a price equal to 105% of the highest price seen during trading of the previous 7 days.
The highest price over the last seven days can you explain this one a bit more seems a bit too easy to manipulate I don't want to see another Sandstorm IPO share rise/drop
With that said due diligence on page 1 completed waits for some good questions from the usual suspects ^^
Welcome to the forums an IPO already that's intense

If also services such as Coinbase stop saying nonsense like 'our users didn't request SegWit', that would be nice. If they only implement it, It would help the network and also help them save millions of dollars in fees for the long term but they are clearly colluding to bring bitcoin down.
Is it not possible for these developers to come ahead with a different sight? Like a blockchain summit or something? Use their knowledge, not to argue, but to decide one thing for all, upgrade just once and prove their work without debating too much? It's these exchanges and other major parts too who are doing bullshit at their end, by not accepting these upgrades or misleading people about the changes already accepted by people.

It's very dangerous for you to trust these non-reputable individuals with your information and for the future of cryptos as a whole, yet no one is discussing this.
You can blame Polymath for this, they don't want to work harder filter to filter puppets, so instead they want your ID.
Edit: There is probably nothing we can do to stop this, because the vast majority of people trying to do airdrops are very likely to hand over their info without a second thought. This has major repercussions, some of the worst repercussions we will see ever in crypto.
The best thing you can do if you're reading this, is to not give in to these new information whores, who are more than likely to flip your IDs on the darkweb for a profit.

There are opportunities everywhere. You just need to discover what it is because not all investments are applicable and can do by anyone. What are your preferred investments? What are your knowledge about those? Asked yourself some questions.
In cryptocurrency, where are you now? what knowledge do you gained?
Passive income is not the literal Passive Income. What I mean here? You still have to work to maintained that passive income. What are those? Like I said, explore your side. You can also consider investments outside the internet world.
Goodluck targeting that massive amounts of passive income.

I personally have never had any issues with authy.
The main reason why I wouldn't use Google authenticator or Authy is because it's not open source. There's open source alternatives which have been mentioned above which are simply better. Before you say Google authenticator is open source, the app which you download on the store is not.
Also, for their multi device feature to work, then your keys need to be stored on a server for it to work. So they certainly keep records/data. These are encrypted by the backup password you set. This is encrypted using AES and a randomly generated salt using PBKDF2. So the data is stored otherwise, it wouldn't be possible to restore access using another device.
