Driving China’s March 31, 2021 news user privacy is an old topic. However, from the actual performance of the past many years, it seems that the protection of user privacy more stays on the slogan, and has not really been well implemented. For example, a recent study found that Android collects 20 times more user data than similar iPhones. I don’t know how the majority of users will feel when they know this news?
According to foreign media reports, research done by a computer science professor at Trinity University in Dublin, Ireland, shows that IOS and Android phones are constantly collecting data and sending them to apple and Google, respectively. According to Professor Doug Leith, a researcher and chairman of the college’s computer system, in the United States, IOS devices and Android devices will continue to transmit data to Apple servers and Google servers from the time SIM cards are inserted.
However, although both IOS and Android devices collect user data, there is still a big difference between them. When the phone is idle, Android devices send 1MB of data every 12 hours, while IOS devices send 52kb. When users use data, it’s even more outrageous. Both IOS devices and Android devices will collect a lot of data from users’ devices. IOS devices are 5.8GB and Android devices are 13gb.
Experts also found that IOS shares information about IMEI, hardware serial number, SIM serial number, phone number, device ID (including UDID and AD ID), location, telemetry, cookie, local IP address and nearby Wi Fi MAC address. Android sends similar data and adds the Wi Fi MAC address of the device, but does not include the location information of the mobile phone, local IP address and nearby Wi Fi MAC address.
For the phenomenon of mobile phone collecting user data, the research points out that “at present, there is almost no choice to prevent this kind of data sharing”. This also means that as long as users use mobile phones, they must accept the reality of the collected data.
However, Google does not seem to agree. Google believes that data collection is the core function of any connected device. At the same time, Google also questioned the effectiveness of the experiment, believing that Leith’s method had defects, and the experiment could not capture data such as UDP / quic traffic.
