Bafuputsi ba David Ben-Gurion University (Israel), ho ithuta mekhoa e patiloeng ea phetiso ea data ho tsoa ho likhomphutha tse ka thoko, mokhoa o mocha oa ho hlophisa mocha oa puisano o thehiloeng ho feto-fetoha ha lets'oao ka phetoho e sa bonahaleng ea khanya ea skrine ea LCD. Ka lehlakoreng le sebetsang, mokhoa ona o ka sebelisoa, ka mohlala, ho fetisetsa linotlolo tsa encryption, li-password le data ea lekunutu ho tsoa khomphuteng e se nang khokahano ea marang-rang mme e tšoaelitsoe ke spyware kapa malware.
Ho kenyelletsa "1", ho sebelisoa ho eketseha ha khanya ea karolo e khubelu ea 'mala oa pixel ka 3% ho latela boleng ba lebitso,' me "0" ke ho fokotseha ha khanya ka 3%. Liphetoho tsa khanya tse etsahalang nakong ea phetisetso ea data ha li bonahale ho batho mme mokhoa ona o ka sebelisoa le ha opareitara e ntse e sebetsa komporong eo data e nkiloeng ho eona. Tlhahisoleseding e fetotsoeng ka liphetoho tsa khanya e ka ntšoa likhatisong tsa video, ho kenyelletsa le tse hapiloeng ke lik'hamera tsa CCTV, lik'hamera tsa marang-rang le li-smartphone.
Sekhahla sa phetisetso ke likotoana tse 'maloa feela motsotsoana. Ka mohlala, ha re sebelisa k'hamera ea video ea Sony SNC-DH120 720P le k'hamera ea websaete ea Microsoft Lifecam, re khonne ho fumana data ho tloha bohōle ba limithara tse 9 ka lebelo la 5-10 bits ka motsotsoana. Ha u sebelisa khamera ea smartphone ea Samsung Galaxy S7, sebaka sa ho amohela mats'oao se ile sa fokotsoa ho isa ho mithara e le 'ngoe le halofo,' me lebelo la phetisetso le theohetse ho 1 bit ka motsotsoana.
mabapi le khetho ea mekhoa e meng ea phetisetso ea data e patiloeng e ithutoang ke bafuputsi ba sebelisang mefuta ea ho lutla ea motlakase, ea acoustic, e futhumatsang le e bobebe:
- - ho romela data holim'a mohala oa matla, ho laola mojaro ho CPU ho fetola tšebeliso ea matla;
- () - lintlha tse ka ntle ho sebaka se utloahalang ka libui kapa li-headphone ntle le ho sebelisa microphone;
- () - ponts'o ea ho ntšoa ha data ho sesebelisoa se ka kamoreng e sirelelitsoeng (Faraday cage) ka tlhahlobo ea li-oscillations tse fokolang tse etsahalang nakong ea ts'ebetso ea CPU;
- () - ho ntšoa ha data ho ipapisitse le ho lekanya ho feto-fetoha ha matla a khoheli ho etsahalang nakong ea ts'ebetso ea CPU;
- () - phetisetso ea data ka lebelo la ho fihla ho li-byte tse 60 motsotsoana ho tloha ho PC ho ea ho smartphone ka tlhahlobo ho smartphone e nang le tuner ea FM ea tšitiso ea seea-le-moea e etsahalang ha ho bonts'a tlhahisoleseling skrineng;
- () - phetiso ea data ka sebaka se ka bang 40 cm ka lebelo la 1-8 bits ka hora ka ho lekanya ho fetoha ha mocheso oa nyeoe ea PC;
- () - ho ntša data hole ho fihla ho limithara tse 30 ka ho theha tšitiso ea motlakase ho maqhubu a marang-rang a GSM a nkiloeng ke smartphone;
- () - phetisetso ea data ka lebelo la li-bits tse 180 ka motsotso ka tlhahlobo ea melumo e entsoeng ha ho sebetsoa hard drive;
- () - phetiso ea data ka lebelo la ho fihla ho li-byte tse 80 motsotsoana ka tlhahlobo ea tšitiso ea motlakase e entsoeng nakong ea phihlello ea lisebelisoa ka boema-kepe ba USB;
- () - tšebeliso ea LED e bontšang mosebetsi oa hard drive e le mohloli oa phetisetso ea data ka lebelo la ho fihla ho li-bits tse 120 ka motsotsoana ha u sebelisa k'hamera e tloaelehileng ea video e le moamoheli le ho fihlela ho 4000 bits ka motsotsoana ha u sebelisa sensor e khethehileng;
- () - phetiso ea data ka lebelo la ho fihla ho li-bits tse 900 ka hora ka ho feto-fetoha ha molumo oa pholileng e sebelisoang ho pholisa CPU;
- () - phetiso ea data ka infrared LED ea lik'hamera tse behang leihlo ka lebelo la li-bits tse 100 motsotsoana le bohole ba k'hilomithara;
- () - phetiso ea data ka lebelo la ho fihla ho li-bits tse likete tse 10 motsotsoana ka ho panya ha li-LED ho li-router le li-switches;
- — phetiso ya data ka ho painya ho sa bonahaleng kapa ka diphetoho tse fapaneng tsa setshwantsho se skrineng.
