Proxy for ReCAPTCHA solution

Most popular sites and web services use bot protection - captcha. It is a test for recognizing users and cutting out bots. Captcha helps fight spam and online fraud, but unfortunately it can also be a problem for many people working online. For example, captcha can reduce the speed of parsing from sites and search engines by several times.

Working principle of ReCaptcha

The original version of the anti-bot protection was called "Captcha", but with the subsequent purchase of the technology by Google, the system was called "ReCAPTCHA" and several updated versions: B1, B2, B3 and Corporate. Compared to the first version, which offered typed text, subsequent versions were trickier. Now, the updated system analyzes the user's unique fingerprints and his behavior when recognizing captchas. For example, the type of device, OS version, ip-address, authorization in Google services, and even the user's previous activity can be taken into account.

In the new versions, the ReCAPTCHA script generates a user score based on the analyzed data: from 0.0(Bot) to 1.0(Human) when solving the test. When generating the score, adaptive risk analysis is used, which includes not only unique identifiers, but also, as discussed earlier, the user's behavior. Then, depending on the score, the user can move on or leave for additional validation.

For example, when passing the captcha from a personal phone with authorized services Google score will be 0.9 points. But when passing the test in the browser of the computer without logging into Gmail and with a public address score may fall to 0.3. Low score, most likely, will cause the repeated passage and increase the frequency of occurrence of the test when working with other pages of the site, which can greatly complicate the work. Therefore, to bypass ReCAPTCHA you need to take the fingerprint swap seriously.

Proxy for ReCaptcha bypass

When sending infrequent requests to solve captchas you can not worry about sanctions from the system, but when you need to solve a large number of captchas, without a change in ip-address can not do. For example, when mass mailing or parsing keys from search engines.

For example, when sending multiple requests from the same ip-address ReKapcha may increase the number of images displayed or the frequency of their appearance. Also, the system may block the device - in this case, access to the resource will be blocked or captcha will be constantly reloaded, not allowing to get to the page even in cases where the test was successfully completed. Avoid this by changing your ip address with a proxy server. It will help hide the real ip, reducing suspicious activity in the eyes of Google protection.

Which proxies should be selected to bypass ReCAPTCHA

The best choice for solving captchas is Dynamic IPv6 with a change of IP after each request. When such proxies are connected, each request to ReCAPTCHA will come from a new IP.

It is not recommended to use free proxies. As we wrote before, their IPs are entered into "Spam Lists" and are most often in the Black List of Google and other services. When using free proxy servers the captcha appears with great frequency, which may result in high costs when using paid services to solve ReCaptcha.
