This is the more preferred method as audio recognition is much simpler than image recognition, which yields lower computational resources and time. So can we use this method to solve Recaptcha? Yes! Using AI to detect human speech is a very mature technology, in a matter of fact, it has been integrated into Siri, Google Assistant, and Bixby to understand user commands. (2) Audio Recognition Challenge - This challenge requires the user to listen to a sound clip and decipher the “human speech” from it. Image classification algorithm struggles to locate the car Yes, because it is simple for the algorithm to classify objects within one single frame, as shown in the figure below. So it shouldn’t be a problem to “select all images with a bicycle” right? Yes and no. To solve this, it seems like a simple task for AI as we have many image classification algorithms such as GoogLeNet, ResNet, and MobileNet that can be trained to classify thousands of objects. (1) Image Recognition Challenge - This challenge requires the user to identify objects in a 3 x 3 frame. Understanding AI TechnologiesĪs I previously mentioned, there are two ways to solve the Recaptcha challenge (1) Image Recognition and (2) Audio Recognition. So the question is, can we use these technologies to solve Recaptcha automatically for us? The short answer is YES, but it requires you to have some understanding in the field of AI and machine learning technologies. With the advancement in AI and Machine learning technologies, we have amazing technologies such as Google Assistant, Telsa self-driving cars, and Deep Mind Alpha Go - the AI who defeated the world champion in 2016. Their service costs 0.0025USD per challenge. Another way to solve this is to use Recaptcha Solver API from companies such as 2Captcha, where they employ humans to solve the ReCaptcha for you. While the bot can choose to solve either the image or audio recognition challenge, both are equally challenging. This is done by asking our bot to solve “complicated” puzzles that only humans can apprehend. It stops our bot from web scraping and blocks our automation software from booking our favorite concert tickets. Recaptcha is a huge roadblock for any automation engineers.
