Recently, a music account of the late singer Coco Lee was logged in abnormally. According to media reports, some netizens automatically logged into Li Wen's account when registering for this music platform account using their newly created mobile phone number. The platform customer service responded that this incident was caused by the "operator's secondary account release" which resulted in the account being "inherited" by a new user, and has been urgently unbound. This incident has aroused public attention to the protection of digital heritage. In the digital age, platform accounts not only contain property assets such as virtual currency, but also carry memory content such as chat records, photos, and images. It can be said that the digital trajectory has formed a "second self" intertwined with real life, but there are still shortcomings in the management and protection of digital assets. Previously, platform users have reported that their new phone number cannot register for apps such as WeChat. After investigation, it was found to be a second-hand account that has been linked to multiple platforms by the original user and cannot be re registered. Some users who use "second-hand accounts" frequently receive notifications of unfamiliar express delivery, shopping and consumption reminders, and even encounter bombardment of debt collection calls and text messages. The shortcomings of digital asset management urgently need to be addressed. Many online platforms use mobile phone verification codes as the only registration or login verification tool. After the phone number is deactivated, there is a risk of leakage to the platform account it is bound to. At the legal level, although the Civil Code recognizes the legal status of virtual property on the internet, it does not clarify whether social account data belongs to inheritable property, and further rules need to be refined at the operational level. Improving the rules of digital asset management requires the joint efforts of multiple parties. Laws and regulations need to clarify the legal status of social media accounts and other data, and establish a classification inheritance system. The platform should bear management responsibilities, such as establishing a "inheritance" channel for the deceased's account and building a strong information security defense line technically. The relevant rules have been made clear on the platforms such as Station B and Tiktok, and the account usage rights can be frozen after the relatives' authentication. Operators also need to be more proactive in disclosing information about "second-hand accounts", informing buyers whether they belong to "second-hand accounts" before selling them, and establishing an information linkage mechanism with the platform. The public should also enhance their awareness of digital asset management and protection, and unbind platform accounts before abandoning mobile phone numbers. In today's digital space, which is increasingly becoming a carrier of emotional attachment, only by combining technology, institutions, and humanistic care can we place our trajectories and memories in the virtual world.
