# 12306 once applied for a patent to prevent automatic ticket grabbing.

US Stock Research News, as the holiday approaches and travel peaks, many netizens choose to purchase train tickets through third-party platforms. According to China Railway, the official platform 12306 has never authorized any third-party platforms to sell train tickets, and purchasing through third parties poses risks such as information security and ticket authenticity.

Tianyancha intellectual property information shows that 12306's affiliated companies, China Railway Cheng Technology Co., Ltd., the Electronic Computing Technology Institute of China Academy of Railway Sciences Group Co., Ltd., and Beijing Jingwei Information Technology Co., Ltd., applied for a patent titled "A Method and System for Preventing Automated Ticket Grabbing, Device, and Storage Medium" in November 2021. The abstract indicates that the invention uses scalable vector graphics (SVG) technology to design a ticket purchase request method based on obfuscated SVG commands and a behavioral verification method based on character reasoning to increase the difficulty of automated ticket grabbing.
