Study finds Android shares 20x more data with Google than iOS does with Apple

A study conducted by a professor of computer science at Trinity College Dublin found that a typical Android handset collects some 20 times more data about its user than a comparable iPhone.

According to researcher Doug Leith, who also serves as Trinity College's chair of computer systems, both iOS and Android continuously collect and send so-called telemetry data back to Apple and Google, respectively, reports ArsTechnica. This information ranges from inserting a SIM card into a smartphone to interacting with hardware and apps.Data collection routines might run when a user is not logged, has opted out of data collection in privacy settings and when the handset sits idle. Leith found iOS shares information relating to IMEI, hardware serial number, SIM serial number, phone number, device IDs including UDID and ad ID, location, telemetry, cookies, local IP address and nearby Wi-Fi Mac addresses. Android sends similar data, adding device Wi-Fi MAC address but not tapping a handset's location, local IP address and nearby Wi-Fi Mac addresses.
