nowadays, the update and iteration rate of mobile phones is getting faster and faster, and it is common for people to replace the electronic products around them. however, where those retired devices go has become a problem that most people ignore. recently, cctv.com reporters found that when dealing with old mobile phones, those personal information that "seems to be deleted but is not deleted" poses a security risk that can be exploited by criminals.
the reporter brought a mobile phone with all applications, call records, text messages and photo albums deleted to beijing zhongguancun science and technology electronics city, where many businesses provide "data recovery" services.
in 20 minutes, all the information such as application cache, photo album, call log, and text messages that the reporter had deleted "came back to life" and appeared on the computer screen miraculously. from beginning to end, the boss did not check the reporter's personal information, but only asked "is this your phone?" although the boss said that most people came to restore important information in their phones because their phones were soaked in water or broken, this service also leaves room for criminals to steal personal information.
the reporter learned that formal companies have their own set of processes for dealing with personal privacy issues: through multiple data erasures and overwriting, they can prevent user data from being maliciously restored and perform deep data clearing.
however, compared with small workshops, the "regular army" has a narrow coverage and is limited by factors such as operating costs, resulting in the recycling prices of regular enterprises having no competitive advantage. many users who care more about "how much it sells for" will give up recycling through regular channels.
experts said that since 2012, the state has guided the development of the electrical appliance recycling industry by issuing funds and other means, and has achieved certain results to date: the recycling rate of televisions has reached more than 94%, and the recycling rate of refrigerators has reached more than 77%. however, in the current system, there has been no supporting system and implementation details for the newly added categories of mobile phones and printers in the catalog. on the one hand, the policy has not been implemented, and on the other hand, the industry supervision is weak, which has led to the repeated "illegal dismantling" of electronic products, including mobile phones.
in response to the privacy leakage problem in the recycling of used mobile phones, some experts suggest setting up community recycling points, establishing a standardized and orderly electronic waste recycling system, and establishing an extended producer responsibility system. using methods such as "whoever makes it recycles it, whoever produces it handles it, and whoever pollutes it pays", we can better help the recycling system operate better.
