Eliminating Captcha's w/ Bitcoin

[bbit]

Captcha's are so annoying I figured there must be an easy way to eliminate them using bitcoin.  I would think  this would help keep the bitcoin economy going.  One idea would be a full-cycle solution so basically if you don't have any bitcoins to release the captcha in front of you you can dip in and pick up a few bits through a "send me a few bits" system - to send against the captcha payment address of course if you do have some you would just send a few bits to it and again hit the "send me a few bits back"  system . I dunno just thinking out loud ....

What's to prevent spammers from automatically sending bits?  Difficulty in obtaining bitcoin?

good point so maybe take out the part about getting bits of bitcoin lol ...hmm how about a system that is paralleled to the traditional captcha saying if you have bits of bitcoin send and then it passes it back to you  ?

What publio meant was what will stop spammers to automate the process of sending/receiving bitcoins to pass your protected page?

If you can figure out how to sell captcha solutions of 95% accuracy rate on recaptcha for less than USD $1.35 (about 0.25 BTC at todays price) per 1000 solutions, then you will have found a business model.

Indeed. We're currently spending about $600 a week on bulk captcha solutions from imagetyperz and get their best pricing, but I think there is still room for improvement as the service is paid by paypal or credit card. I also believe they are just reselling some foreign labor using some kind of data entry platform, and that probably involves more fees to get the payments to the individual workers who end up typing these things. Now I have no idea what country or language the actual workers who type the captcha solutions are in, but they are there doing it reliably 24/7 and I'm thinking that there must be ways to connect those workers with the $$$ being paid for the bulk services without the middle men or fees, and the end result should be the most cost competitive captcha solving service out there. Having such a service only available for Bitcoin but at a clearly better pricing will encourage the whole black-hat-seo industry to think about getting into Bitcoin simply as a matter of operational cost savings.

I had no idea about this stuff. So your basically saying there are services that have human beings breaking captcha's and people pay for them ? lol

Hmmmm good point ^^ never thought about it like that.

Or combine a bit of captcha and btc?
The image will have some random tiny amount to send them, you send it, then enter a unique receive address for the refund. That way the costs to spammers are 2 way. 1 for the btc amount, then for the btc they have to spend to go through.

So all you need is to read some numbers from a picture, enter an address, create blockchain bloat and you get your BTC back anyways?

Anyways: if you make it expensive to pass a captcha, you will scare off regular users, if it is dead cheap, bots would just pay.

What might work is a (web-)miner and a getwork source. Mine one or more difficulty 1 shares and you can enter. Still it might be possible for bots to mine themselves or rent hashing power, but it could have a high enough cost to keep them from your page and is easy enough to do for regular users.

[barbarousrelic]

Idea: Instead of a captcha, send a 1 bitcoin deposit. After a certian amount of time they determine you arent a spammer, and they send you your btc back. This could at least work on forums and wikis.

In hindsight do you find it that surprising?  Captchas exist to stop "something" automated.  That automation is obviously valuable otherwise captcha or no captcha nobody would be automating it.

If the value of the automation is > slave wages by uneducated workers in 3rd world then .... there is a business to provide "human talent" to bypass captchas.

There is a direct relationship between shares & coins.
1 diff 1 share =  1 BTC / (current difficulty)
Even 1000 diff 1 shares <= 0.07 bitcents.
So there is no real advantage to using shares instead of coins.  Coins are simply "purchased shares".

A modest fee would make bypass for the purposes of spamming prohibitively expensive.
Current captcha bypass solutions are on the order of 25 bitcents per 1K solutions.

That is 0.04 BTC per capthca bypass.   Allowing legit users to bypass the captcha for 1 bitcent would increase spammer's cost by 25x while not costing user much.

I would love a captcha bypass system for 1 cent per capthca.  Eventually as more users use the "humancent" system you could make the captcha more timeconsuming driving up spammer's cost and eventually move to a "no-captcha" system where user must pay a micro tx to continue.

So basically, if you could set it up so you have to send 25 cents worth of BTC to an address, then after a certain amount of time (a month?) you get it back...that would be no big deal to regular people. You spend a few bucks a month on captchas and get it back.

But for spammers...doing 1000 at a time, you have to spend $250. Then wait to get that back. That cuts into the monthly budget, $250 for every 1000 captchas used.

Basically, this is what I was getting at. What you could do even is do a "strongcoin" type element where you "unlock" the content - there would be a "pool of bitcoin" that could be used for people to unlock the captcha/content.

This is where I was heading with all of this. Basically, help eliminate all the hassles with captcha's.
