The phone was turned on secretly by someone else. What privacy will Bluetooth and synchronization reveal?

Privacy on the mobile phone may be leaked, such as SMS records, contacts, photos, files and so on.

In view of the problem that the privacy of mobile phone is leaked, we can download the mobile phone housekeeper to protect it, which can encrypt important privacy information to ensure that personal privacy is not exposed and realize comprehensive privacy protection.

Add a contact in the personal space of the mobile phone housekeeper. After selection, private contacts and your past messages and phone records will be "cut" into private space. Press and hold the added private contact to initiate the first private message.

Extended data

The Bluetooth address in some Bluetooth devices is unique. Once this address is associated with the user, his actions can be recorded, and the privacy of the user can hardly be guaranteed. Then even if the user does not use the Bluetooth device in the original place, as long as the Bluetooth address of the device is "marked", the attacker can still know which Bluetooth data belongs to the user.

For example, in the Bluetooth data packet broadcast by Windows 10 system, some data are different on each device and will change periodically. Similar to the randomized Bluetooth address, its original intention is to prevent being tracked by "interested people", but the period of this part of data change is not synchronized with the period of Bluetooth address change, and attackers can link them through careful analysis and interpretation to realize continuous tracking of devices.

Users should try to reduce the number of Bluetooth pairing and choose a safe place to avoid others seeing the pairing password. At the same time, when using mobile phones, users should try not to connect and pair untrusted devices, and only pair with familiar devices.
