Abstract: In the Internet era, whoever has mastered the data will have mastered the core competitiveness. “No competition, no market.” Legal and orderly competition can promote the healthy and rapid development of market economy, and vice versa become a stumbling block for the development of market economy. Reptilian technology is originally designed to help people capture specific data and improve data analysis ability, but if used improperly, such as stealing other people's data, it may be suspected of civil infringement, administrative violations, or even criminal offence.

Key words: data, competition, steal, Web crawler, personal information

摘要： 在互联网时代，谁掌握了数据谁就掌握了核心竞争力.“没有竞争就没有市场”，合法有序的竞争能促进市场经济健康快速发展，反之则成为市场经济发展的绊脚石.爬虫技术本来是帮助人们抓取特定数据，提高数据分析能力，但若使用不当，如窃取他人数据的，则可能涉嫌民事侵权、行政违法，甚至是刑事犯罪.
