第二章：专业检测工具与方法

2.1 多源验证技术

主流IP定位服务对比

# 多源地理定位验证脚本
import requests
import json

def verify_ip_location(ip_address):
    services = {
        'ipapi': f'http://ip-api.com/json/{ip_address}',
        'ipgeolocation': f'https://api.ipgeolocation.io/ipgeo?apiKey=API_KEY&ip={ip_address}',
        'maxmind': f'https://geoip.maxmind.com/geoip/v2.1/city/{ip_address}',
        'ipinfo': f'https://ipinfo.io/{ip_address}/json'
    }

    results = {}

    for service, url in services.items():
        try:
            response = requests.get(url, timeout=10)
            results[service] = response.json()
        except Exception as e:
            results[service] = {'error': str(e)}

    return analyze_consistency(results)

def analyze_consistency(results):
    """分析多源定位结果一致性"""
    locations = []

    for service, data in results.items():
        if 'error' not in data:
            locations.append({
                'service': service,
                'country': data.get('country', ''),
                'region': data.get('region', ''),
                'city': data.get('city', ''),
                'lat': data.get('lat', 0),
                'lon': data.get('lon', 0)
            })

    return calculate_accuracy_score(locations)

2.2 延迟测试验证法

基于RTT的地理验证

import ping3
import time
import socket
from geopy.distance import geodesic

def rtt_geolocation_verify(proxy_ip, claimed_location):
    """基于延迟的地理位置验证"""

    # 已知地理位置的参考服务器
    reference_servers = {
        'us-west': {'ip': '8.8.8.8', 'location': (37.4419, -122.1419)},
        'us-east': {'ip': '4.4.4.4', 'location': (40.7589, -73.9851)},
        'eu-west': {'ip': '1.1.1.1', 'location': (51.5074, -0.1278)},
        'asia-east': {'ip': '114.114.114.114', 'location': (39.9042, 116.4074)}
    }

    measured_delays = {}

    for region, server in reference_servers.items():
        delay = measure_proxy_delay(proxy_ip, server['ip'])
        if delay:
            measured_delays[region] = {
                'delay': delay,
                'distance': geodesic(claimed_location, server['location']).kilometers
            }

    return analyze_delay_consistency(measured_delays)

def measure_proxy_delay(proxy_ip, target_ip):
    """测量通过代理的延迟"""
    try:
        # 模拟代理连接延迟测试
        start_time = time.time()

        # 这里应该通过代理进行连接测试
        # 简化示例：直接ping目标
        delay = ping3.ping(target_ip)

        return delay * 1000  # 转换为毫秒

    except Exception as e:
        return None

def analyze_delay_consistency(delays):
    """分析延迟与距离的一致性"""
    consistency_score = 0
    expected_ratio = 0.1  # 预期延迟/距离比值(ms/km)

    for region, data in delays.items():
        actual_ratio = data['delay'] / data['distance']
        deviation = abs(actual_ratio - expected_ratio) / expected_ratio

        if deviation < 0.5:  # 50%误差范围内
            consistency_score += 25

    return min(consistency_score, 100)

2.3 DNS解析验证法

基于DNS的地理一致性检测

import dns.resolver
import socket

def dns_geolocation_verify(domain, proxy_ip):
    """基于DNS解析的地理验证"""

    try:
        # 直接DNS解析
        direct_resolver = dns.resolver.Resolver()
        direct_result = direct_resolver.resolve(domain, 'A')
        direct_ips = [str(rdata) for rdata in direct_result]

        # 通过代理DNS解析（需要配置代理DNS）
        proxy_resolver = dns.resolver.Resolver()
        proxy_resolver.nameservers = [get_proxy_dns(proxy_ip)]
        proxy_result = proxy_resolver.resolve(domain, 'A')
        proxy_ips = [str(rdata) for rdata in proxy_result]

        # 分析IP差异
        return analyze_dns_consistency(direct_ips, proxy_ips, proxy_ip)

    except Exception as e:
        return {'error': str(e), 'verification_score': 0}

def get_proxy_dns(proxy_ip):
    """获取代理地区的DNS服务器"""
    region_dns = {
        'US': '8.8.8.8',
        'EU': '1.1.1.1',
        'ASIA': '114.114.114.114'
    }

    # 根据proxy_ip确定地区
    region = detect_ip_region(proxy_ip)
    return region_dns.get(region, '8.8.8.8')
