Recently, a message about "logging into Li Wen's NetEase Cloud Music account with a new phone number" has become a hot search topic. A netizen registered for NetEase Cloud Music with a newly created mobile phone number. After entering the SMS verification code, the page automatically redirected and directly logged into the official authentication account of the late singer Coco Lee. Although the operator immediately contacted the new account owner for corresponding handling afterwards, it exposed the problem of how to "inherit" the current "digital heritage". According to the "Telecommunications Service Standards", Chinese telecommunications operators can reactivate and enter the market after 90 days of number cancellation, and these reactivated numbers are called "secondary numbers". The "secondary number" has improved the utilization rate of resources, but at the moment of the rapid development of mobile Internet, users also have some problems in using the "secondary number". If the original user used this number to bind to an Internet application and did not unbind it when logging off the number, the new user of the "secondary number" may encounter a situation where he or she cannot register or bind to some Internet applications. This has also sparked current thinking about 'digital heritage'. If the original user forgets or fails to unbind their registered account on various platforms in a timely manner, the new owner of this number can take over the "digital legacy" of their predecessors with just one click with a simple SMS verification code. These 'digital footprints' record everyone's growth process, interpersonal relationships, and inner world, and are an important component of our digital identity. In fact, Li Wen's case is just the tip of the iceberg regarding the issue of "digital heritage". At the same time, the Li Wen account incident has also raised a key question: who should be responsible for such "digital heritage" accidents? How should similar 'digital legacies' be inherited in the future? On the surface, operators, Internet platforms and users all have responsibility considerations. According to regulations, the operator's recycling and re release of deactivated phone numbers constitutes a resource cycle. Under the guidance of the Ministry of Industry and Information Technology, telecom operators and Internet enterprises, relying on the code number service platform of China ICT Academy, launched the "secondary number renewal" service, focusing on solving the problem of "secondary number" registration and binding to Internet applications that have long plagued industry enterprises and users. However, in practical operation, there are still certain limitations in solving the problem. Multiple reasons, such as incomplete unbinding when users close accounts, whether the Internet platform handles unbinding in a timely manner, and frequent APP update iterations, may lead to incomplete and thorough unbinding before sales of "secondary numbers". For Internet platforms, it is difficult to know whether the user's registered mobile phone number has changed hands. When users register, platforms often exempt their responsibilities to the extreme through lengthy user agreements, but do not provide users with equivalent rights, such as convenient channels for inheriting and transferring "digital assets". However, users generally lack awareness of digital asset management and fail to unbind various accounts in a timely manner before changing their phone numbers. Faced with the challenges of protecting and inheriting "digital heritage", it is necessary to build a dual protection network of "technology+system". Firstly, through blockchain technology, the immutability and permanent existence of "digital heritage" can be ensured, enabling it to be truly and completely passed down to future generations. Secondly, at the institutional level, legislative improvement can be promoted, and specialized laws can be formulated to provide clear legal basis and guarantees for the protection of "digital heritage". At present, it is particularly important to clarify the definition, scope, inheritance rules, and platform responsibilities of "digital heritage", and establish registration, inheritance procedures, and platform responsibility norms for "digital heritage". For individual users, it is necessary to enhance their awareness of digital asset management. Regularly organize important digital assets, clearly label which ones need to be retained and which ones can be deleted, and even consider establishing "digital heritage" heirs. At present, some users have shared the method of unbinding old accounts through "Yizheng Tongcha", reminding to avoid similar risks. The race between law and technology is still ongoing. The EU's Digital Single Market Copyright Directive provides inspiration for the refined governance of "digital heritage" by clearly distinguishing between "inheritable property" and "inviolable personality rights". In China, from Shanghai's "Suishenban" to Zhejiang's "Zhe Li Ban", many places have begun to explore "one thing after oneself" services. Looking forward to finding a solution that belongs to this era between digital immortality and complete disappearance in the near future through multi-party collaboration. (New Society)
