#Solve captcha with flash image code
But we can write a code that pipes the captcha to someone else to help us solve it! Being a developer, I like automating as many things as possible, so why not automate a captcha solving service? First thing to consider about this is the fact that captchas are designed so that they can only be solved by humans so we can't write a code to solve a captcha. Quite recently I discovered that the answer to this question is not too far fetched from the question itself. Then it bags the question, How can we implement a secure testing system that is user friendly? Regardless of the loss of customers we are striving to make the web a more secure place and for this one personally I think the benefits outweigh the drawbacks. Most people do not find it funny or worth while to fill out a captcha and as such websites that use captchas has roughly close to 40% conversion rate where as websites without captchas have close to 60% conversion rate. One thing with captchas is the fact that they don't really contribute as much to a good user experience. This is especially useful if you have meaningful content on your website and you generally reach a lot of customers, captchas are also used for fraud detection. There has to be a way for limiting or preventing robots from providing us with this information and that is why a captcha test exist, to tell humans apart from computers by providing simple cognitive test, that humans can understand but makes no sense to a robot. It makes no sense to populate our database with a list of fake information from users who do not exist and we cannot reach out to.
These robots often interact with a page as much as a human does and they fill out forms and all the rest too, however the information provided to us by these robots are of no use since they are fake and autogenerated.
So what is a CAPTCHA service anyway? A captcha service is a kind of test used to distinguish humans from robots that crawl a web page, there are many instances where bots are used to crawl up websites, most likely to scrape information of the web. Sometimes a captcha test is also called a reverse Turing test because it administered by a computer and not a human. This is the most basic type of Captcha test we see on the internet today. The first type of captcha tests were invented in 1997 and it required someone to correctly evaluate a sequence of letters or numbers in a distorted image displayed on the screen. The term captcha was coined by Luis Von Ahn, Manuel Blum, Nicholas J. This is a mouthful and I'm grateful we call it CAPTCHA. CAPTCHA is an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. However let's take another perspective at what captcha is as a service and why we should be using one. I never thought of a need for a captcha service for my website, hell I hate doing captchas.
