Haufinyane tjena, ho IEEE Symposium on Security and Privacy, sehlopha sa bafuputsi ho tsoa Computer Laboratory ea Univesithi ea Cambridge. mabapi le ts'oaetso e ncha ea li-smartphone e lumelletseng le e ntseng e lumella basebelisi ho beoa leihlo Marang-rang. Bofokoli bo sibolotsoeng bo ile ba fetoha bo ke keng ba etsolloa ntle le ho kenella ka kotloloho hoa Apple le Google mme bo fumanoe mefuteng eohle ea iPhone le mefuteng e seng mekae feela ea li-smartphones tse sebelisang Android. Mohlala, e fumaneha mefuteng ea Google Pixel 2 le 3.
Litsebi li tlalehile ho sibolloa ha kotsi ho Apple ka Phato selemong se fetileng, mme Google e ile ea tsebisoa ka December. Kotsi e ne e bitsoa SensorID mme e khethiloe ka molao CVE-2019-8541. Apple e felisitse kotsi e boletsoeng ka ho lokolloa ha patch bakeng sa iOS 12.2 ka Hlakubele. Ha e le Google, ha e so arabe tšokelo e boletsoeng. Leha ho le joalo, re pheta hape hore le hoja tlhaselo ea SensorID e ne e etsoa habonolo hoo e batlang e le mefuta eohle ea li-smartphone tsa Apple, li-smartphone tse fokolang haholo tse sebelisang Android li ile tsa fumanoa li le kotsing ho eona.
SensorID ke eng? Ho tsoa ka lebitso ho bonolo ho utloisisa hore SensorID ke sekhetho se ikhethileng sa li-sensor. Mofuta o mong oa signature ea dijithale ea sesebelisoa, eo maemong a mangata e lumellanang le smartphone e itseng, ka hona, hoo e ka bang kamehla ke ea motho ea itseng.
Ka lebaka la boiteko ba bafuputsi ba ts'ireletso, ho saena joalo e ne e le sete ea data mabapi le ho lekanya magnetometer, accelerometer le gyroscope sensors (ka mabaka a totobetseng, tlhahiso ea li-sensor e tsamaisana le ho hasana ha litekanyetso). Lintlha tsa calibration li ngotsoe ho "firmware" ea sesebelisoa fekthering, 'me e u lumella ho ntlafatsa ts'ebetso ea li-smartphones tse nang le li-sensor - ho eketsa ho nepahala ha boemo le karabelo ea smartphone metsamaong. Ha u sheba leqephe la Marang-rang u sebelisa sebatli leha e le sefe kapa ha u bula sesebelisoa, hangata smartphone e matsohong a hau e lula e sa sisinyehe. Liwebsaete li bala ka bolokolohi data ea calibration ho ikamahanya le smartphone mme sena se etsahala hang hang. Sesupo sena se ka sebelisoa ho latela mosebelisi ea seng a tsebisitsoe libakeng tse ling. Moo a eang, seo a se thahasellang. Ka sebele mokhoa ona o molemo bakeng sa papatso e lebisitsoeng. Hape, ka liketso tse bonolo, sekhetho se joalo se ka amahanngoa le motho ka liphello tsohle tse latelang.
Bofokoli bo felletseng ba li-smartphones tsa Apple ho tlhaselo ea SensorID bo hlalosoa ke taba ea hore hoo e ka bang li-iPhones tsohle li ka hlalosoa e le lisebelisoa tsa premium, tseo tlhahiso ea tsona, ho kenyeletsoa le li-sensor tsa feme, e leng tsa boleng bo holimo. Tabeng ena, scrupulousness ena e ile ea hlōleha k'hamphani. Esita le ho tsosolosa fektheri ha ho hlakole signature ea digital ea SensorID. Li-smartphone tse tsamaisang Android ke taba e 'ngoe. Ka kakaretso, tsena ke lisebelisoa tse theko e tlaase, tseo litlhophiso tsa fektheri li sa tsamaeeng ka seoelo le li-sensor calibration. Ka lebaka leo, boholo ba li-smartphones tsa Android ha li na signature ea dijithale ho etsa tlhaselo ea SensorID, leha lisebelisoa tsa premium li netefalitsoe hore li tla bokelloa ka boleng bo nepahetseng mme li ka hlaseloa ho latela data ea calibration.
