According to the People's Daily, when ordering takeout, receiving express delivery, or making online car hailing calls, do you often worry that your phone number will be used by someone with ulterior motives, leading to personal information leakage and the risk of telecommunications fraud? In the future, such concerns can be reduced. Recently, the Ministry of Industry and Information Technology issued a notice on piloting number protection service business, planning to use the 700 segment as a dedicated code resource for number protection service business, further strengthening personal information protection, regulating intermediate number business, strengthening code resource management, preventing and controlling telecommunications network fraud and non invited commercial marketing information. The number protection service business refers to a business that is entrusted by Internet platform enterprises such as express delivery, takeaway, online car hailing and other enterprises and institutions to assign temporary numbers (also known as "middle number" or "privacy number") to their individual users to replace the real mobile phone number and reduce the risk of personal mobile phone number disclosure. The pilot program for number protection services is of great significance for strengthening personal information protection, preventing and controlling telecommunications network fraud, enhancing the prevention and control of non invited commercial electronic information, and promoting the development and growth of platform economy and private economy. This time, the Ministry of Industry and Information Technology has clearly planned the 700 segment as a dedicated code resource for number protection services. This measure is like a "timely rain", bringing new hope and protection to personal information protection. At present, the Internet economy is booming, and platforms such as express delivery, takeaway, and online car hailing generate massive user communication needs every day. Some companies, for the sake of convenience, directly expose users' real numbers to third parties, and even some unscrupulous merchants sell user information for profit. According to data from the Ministry of Industry and Information Technology, the number of telecommunications fraud complaints caused by number leaks exceeded one million last year. In this context, the "launch" of segment 700 not only reduces the risk of personal mobile phone number leakage, but also has profound significance in preventing telecommunications network fraud, regulating non invited commercial marketing, and can be regarded as a "timely rain" to promote the healthy development of the platform economy. However, although the policy is good, the key is still to implement it. If we want to truly maximize the effectiveness of privacy protection for segment 700, we need to work together from multiple parties. Firstly, enterprises should take on the main responsibility. The platform cannot use intermediate numbers perfunctorily in order to save costs or find it troublesome. Taking ride hailing platforms as an example, not only must drivers be required to use the 700 number range for receiving and delivering orders, but the platform itself must also establish a strict technical testing mechanism to regularly investigate whether there are any violations of bypassing private numbers and directly obtaining users' real numbers. If problems are found, the companies and individuals involved will be severely punished and will not be tolerated. Secondly, regulatory authorities also need to tighten the "safety valve". The relevant departments should establish a dynamic monitoring system to monitor the real-time usage of section 700. Through big data analysis, monitor abnormal call frequency, duration, and other data. Once a certain number is frequently called out in a short period of time, it is necessary to intervene and investigate in a timely manner to see if there are problems such as privacy account abuse and information reselling. At the same time, it is necessary to improve the reporting channels and encourage users to quickly report and promptly handle feedback when they discover that their privacy accounts are not being used properly or that their real numbers have been maliciously obtained, forming a closed-loop management of "supervision reporting rectification". Finally, users cannot act as outsiders. On the one hand, it is necessary to actively understand the usage rules of the 700 segment. In scenarios such as ordering takeout or taking a taxi, be cautious and confirm whether the other party is contacting through a private account. On the other hand, we need to enhance our awareness of personal information protection, avoid filling in phone numbers on untrusted platforms, and develop the habit of regularly clearing mobile application permissions. After all, privacy protection is a protracted battle, and only by raising everyone's vigilance can criminals have no opportunity to take advantage of it. The 700 segment still has a long way to go from planning to truly becoming a tool for privacy protection. Only when enterprises have the responsibility to protect their land, supervise without leaving any blind spots, and users actively participate, can this policy take root and truly safeguard everyone's information security, fulfilling the original intention of protecting privacy.
