Munguva ichangopfuura, paIEEE Symposium pamusoro peChengetedzo uye Chakavanzika, boka revatsvagiri kubva kuComputer Laboratory yeYunivhesiti yeCambridge. nezvekusagadzikana kutsva muma smartphones anobvumira uye achiri kubvumira vashandisi kuti vatariswe paInternet. Kusagadzikana kwakawanikwa kwakazove kusinga gadziriswe pasina kupindira kwakananga kweApple neGoogle uye yakawanikwa mune ese ma iPhone modhi uye mune mashoma mamodhi emafoni anomhanyisa Android. Semuenzaniso, inowanikwa muGoogle Pixel 2 uye 3 modhi.
Nyanzvi dzakashuma kuwanikwa kwekusagadzikana kweApple muna Nyamavhuvhu gore rapfuura, uye Google yakaziviswa muna Zvita. Kusagadzikana kwainzi SensorID uye yakasarudzwa zviri pamutemo CVE-2019-8541. Apple yakabvisa njodzi yakaonekwa nekuburitswa kwechigamba che iOS 12.2 munaKurume. Kana iri Google, haisati yapindura kutyisidzira kwakaonekwa. Nekudaro, tinodzokorora zvakare kuti nepo SensorID kurwiswa kwaiitwa zviri nyore pamhando dzese dzeApple smartphones, mashoma mafoni anomhanyisa Android akawanikwa ari panjodzi.
Chii chinonzi SensorID? Kubva pazita zviri nyore kunzwisisa kuti SensorID yakasarudzika identifier yema sensors. Rudzi rwedhijitari siginicha yemudziyo, iyo kazhinji inofanana neiyo chaiyo smartphone uye, saka, inenge inogara iri yemumwe munhu.
Nekuda kwekuedza kwevaongorori vekuchengetedza, siginecha yakadaro yaive seti yedata pachiyero chemagnetometer, accelerometer uye gyroscope sensors (nekuda kwezvikonzero zviri pachena, kugadzirwa kwema sensors kunoperekedzwa nekupararira kweparamita). Calibration data yakanyorwa mumudziyo firmware pafekitori, uye inokubvumira kuti uvandudze mashandiro emafoni ane ma sensors - kuwedzera iko kurongeka kwenzvimbo uye mhinduro ye smartphone kune mafambiro. Paunenge uchiona peji paInternet uchishandisa chero browser kana uchivhura application, iyo smartphone iri mumaoko ako kashoma kuramba isingafambi. MaSaiti anoverenga akasununguka data yecalibration kuti ajairane neiyo smartphone uye izvi zvinoitika ipapo ipapo. Chiziviso ichi chinogona kuzoshandiswa kuteedzera mushandisi atozivikanwa pane mamwe masaiti. Kwaanoenda, zvaari kufarira. Iyi nzira yakanakira kushambadzira kwakanangwa. Uyezve, kuburikidza nezviito zviri nyore, chiziviso chakadaro chinogona kubatanidzwa kumunhu nemigumisiro yese inotevera.
Kusagadzikana kwese kweApple smartphones kuSensorID kurwiswa kunotsanangurwa nenyaya yekuti angangoita ese maPhones anogona kuverengerwa semidziyo yekutanga, iyo kugadzirwa kwayo, kusanganisira fekitori calibration yema sensors, ndeyemhando yepamusoro. Muchiitiko ichi, kungwara uku kwakakundikana kambani. Kunyangwe kusetazve fekitori hakudzime iyo SensorID siginecha yedhijitari. Mafoni anomhanya Android ndeimwe nyaya. Kune chikamu chikuru, izvi zvishandiso zvisingadhuri, zvigadziriso zvefekitori izvo zvisingawanzo kuperekedzwa ne sensor calibration. Nekuda kweizvozvo, mazhinji mafoni e-Android haana siginecha yedhijitari yekuita SensorID kurwiswa, kunyangwe maturusi ekutanga akavimbiswa kuunganidzwa nemhando yakakodzera uye anogona kurwiswa zvichibva pane calibration data.
