Will cell phone recycling reveal personal privacy? How to avoid it?

It will be leaked. Many mobile phone repair shops in the market have data recovery services, and the Internet is flooded with a large number of data recovery software. These services claim that even if you delete mobile phone data, some data can still be recovered.

For example, official website, the master of Apple's recovery, showed that his software can operate in a "fool-like" way, and quickly recover all kinds of iOS data such as SMS, address book, memo, photos, call records, calendars and reminders. Although the developer of Apple Recovery Master said that to use the software, you must have the right to unlock the phone. But if it is a second-hand mobile phone, obviously, it is natural to gain its authority.

If you really want to sell it, first take out the memory card (this can be ignored for mobile phones without memory cards), and then delete all personal information, including account numbers, address books, text messages, photos, videos and so on. And restore the factory settings of the mobile phone. Store a large number of irrelevant video or music resources on the mobile phone, and ensure that the space of the mobile phone is completely filled and covered several times, so that even if the data is recovered later, it may be the top irrelevant data in the storage.

Extended data

360 experts suggest that the government should set up a recycling mechanism for discarded electronic equipment in the form of policies, give full consideration to users' information security and data security, improve the processing flow and supervision institutions of discarded electronic products, ensure strict implementation of the flow, and build special recycling points when necessary to allow users to safely handle electronic equipment such as mobile phones and computers. At the same time, it is necessary to increase the crackdown and punishment on data leakage.

Huang Xinyi suggested that the relevant waste electronic products recycling enterprises should standardize the management of waste electronic products recycling points, sign cooperation agreements with relevant professional data cleaning service organizations, sign written commitments on user data cleaning and information security, and track, evaluate and supervise them in the implementation process, so as to realize transparent treatment and make users feel more at ease.
