Why do apps de­mand ac­cess to our pho­tos and other data?

BBC Earth (Asia) - - Science -

Apps on mo­bile de­vices live in a ‘Sand­box’. This ac­cess con­trol tech­nol­ogy is built into the op­er­at­ing sys­tem, iso­lat­ing each app from your data, from other apps, and from the hard­ware of the de­vice, in or­der to pre­vent ac­ci­den­tal or de­lib­er­ate dam­age. When an app needs to process some data, it must ask you for per­mis­sion first. This is nor­mally for per­fectly sen­si­ble rea­sons: a photo-edit­ing app needs ac­cess to your pho­tos, or a voice recorder needs ac­cess to the mi­cro­phone. Some­times an app may want ac­cess to more per­sonal in­for­ma­tion be­cause it is try­ing to gather data that could then be used for mar­ket­ing. If you feel your pri­vacy is be­ing in­vaded, the best thing to do is deny ac­cess to your data or sim­ply delete the app. PB
