Crawler Anti-Detection Plugin: Fingerprint Camouflage Tool

Crawlers are always blocked? Teach you to use proxy IP + fingerprint disguise double protection

Friends who do data collection should have encountered this situation: obviously using a proxy IP, the site can still accurately identify the crawler program. This is the time to pay attention to -It's not enough to just change your IP, browser fingerprints reveal your true identityThe first is that the web site can be used to identify the web site's features. Just like wearing a mask to the bank, surveillance can still catch people through gait recognition, and websites can uncover crawlers through browser features.

What is browser fingerprinting? How is it exposed?

Each browser has a unique "identity card" consisting of more than 20 features:

For example, your crawler program always use Chrome 120 kernel, screen resolution fixed 1920 x 1080, the site associated these characteristics and IP, change 100 IP can still block you.

The right way to open a proxy IP

Watch out for these three pitfalls when choosing a proxy IP:

① Don't use static IP pools(Easily tagged)
② Don't generate fingerprints locally(Characteristics too regular)
③ Don't use low quality IP(blacklisted ip for nothing)

Recommend using ipipgo's Dynamic Residential Proxy, theirIP survival cycle controlled at 15-30 minutesThe device fingerprint is automatically switched with each request. Tested with their IP with fingerprint camouflage tool, the collection success rate can be increased from 37% to 89%.

Fingerprint camouflage tool configuration

Using Python's fake_useragent library as an example, remember to use it with a proxy IP:

from fake_useragent import UserAgent
import requests

ua = UserAgent()
headers = {'User-Agent': ua.random}
proxy = {"http": "http://user:pass@ipipgo-rotating-node:1234"}

response = requests.get(url, headers=headers, proxies=proxy)

Key Points:IP and fingerprint must be changed at the same time for each request, ipipgo's API supports automatic generation of new fingerprint parameters, which is much less work than manual configuration.

Frequently Asked Questions

Q: Is it okay to use a free proxy IP?
A: Never! Free IP reuse rate is super high, some even honeypot system. Previously tested, with a free IP + fingerprinting camouflage, 10 minutes to be blocked, change ipipgo's exclusive IP can be stable run for 6 hours.

Q: What parameters should I change for fingerprint camouflage?
A: Focus on changing these 5 items: User-Agent, screen resolution, time zone, WebGL fingerprints, font list. ipipgo backend can preset 20+ device templates and switch them randomly automatically.

Q: Does dynamic IP affect the collection speed?
A: It depends on the quality of the service provider. Like ipipgo's response speed can be controlled within 200ms, faster than many static IP, they built their own server room relay server, unlike others is a second-hand IP resale.

Recommended Protection Programs

Based on our real-world data, we recommend this combination of programs:

ipipgo business edition package (5000IP/day) + Fingerprint camouflage plugin (BrowserGuard recommended)

Be careful to turn onIP and fingerprint linkage mode, so that each new IP carries a brand new device fingerprint. With this setup, an e-commerce platform was continuously captured for 3 days with 0 banning records.

Lastly, I would like to remind you that anti-climbing strategies are being upgraded every month, and simply changing IPs is no longer enough. It is recommended to directly look for support like ipipgoFingerprint Camouflage IntegrationThe service provider, their technicians will help to debug the camouflage parameters, than to toss it yourself to save a lot of effort.
