BIOMATRIC

BIOMETRIC SCANNER KYA HAI ISAKE KYA KYA FAYDE HAI

jaise jaise technology mein sudhaar aate ja rahe hain vaise vaise technology aur badhiya aur behatar hotee ja rahee hai isee tarah security se sambandhit technology bhee pahale ke muqaabale bahut jyaada majboot ho gayee hai. pahale agar kisee computing device ko lock karna padata tha to sirf ham us par kuchh anko ka password laga kar hee use lock kar sakate the. lekin ab ham kisee bhee computing device ko sirf kuchh anko ke password se hee nahin apane body ke parts se bhee lock kar sakate hain. jisse ki vah computing device sirf hamaare body ke part se hee khulegee.



isaka chhota sa example ham fingerprint sensor vaale Smartphone ko dekh sakate hain. jis bhee Smartphone mein fingerprint sensor hoga to vah usee vyakti ke fingerprint se khulega jisaka fingerprint pahle us smartphone mein save kiya gaya hai. to suraksha kee yah technology bahut jyaada majaboot aur badhiya hai. ankon ka password to koyee bhee hack kar sakta hai ya pata laga sakata hai. yahaan tak ki ham andaaja laga kar bhee kuchh ankon ka password tod sakate hain. lekin kisee ke fingerprint ke nishaan ham nahin la sakate. to iseeliye hamaare phone kee suraksha ke liye yah bahut badhiya option hai.

BIOMATRICS KYA HAI

biometrics ek aisa tareeka hai jisakee madad se kisee bhee vyakti ke physiological aur behavioral characteristic ko pahchana ja sakta hai. yah tareeka face,fingerprint, aankh aur voice jaisee cheejo ko pahchaan sakata hai. kisee bhee vyakti ke biometric data ko dobaara nahin banaaya ja sakata ya use churaaya nahin ja sakata. jaise kee hamaare mobile ko unlock karane ke liye ham apane fingerprint ka istemaal kar sakate hain. ya aankhon ka istemaal kar sakate hain. to koyee hamaaree finger ka nishaan nahi bana sakata aur naa hee hamaaree aankhon ko dobaara bana sakata agar hame mobile ko unlock karana hai to usake liye hame apanee finger aur aankhon kee hee jaroorat padegee.

FINGERPRINT SENSORE KA AVISHKAR



fingerprinting ka pahala upayog 9vee shataabdee cheen mein tha, jahaan vyaapaariyon ne apane fingerprints ko lon ke doccument kee verification ke liye istemaal kiya gaya tha joao de barros, ek uropian explorer the joao de barros ne 14 sadee mein fingerprinting pahala system record kiya tha

sabase pahale fingerprint sensor smartphone company motorola ne 2011 mein electrics 4g mein diya aur apple ne 10september 2013 ko iphone 5s ke saath diya tha aur aaj lagbhag sabhee company ke phone mein fingerprint sensor aate hai aur aaj to ATM se lekar attends machine tak fingerprint sensor ka istemaal kiya jaata hai.

FINGERPRINT OPTICAL SCANNER KESE KAAM KARTA HAI
what is fingerprint sensor in mobiles ? how do fingerprint scanners work on phones ? kisee bhee computing device ko lock karne ke liye sabse jyaada finger print sensor ka istemaal kiya jaata hai. kyoki duniya mein sabhee vyaktiyon ke finger ke nishaan alag-alag hote hain to agar koee computing device kisee ek vyakti ke finger se lock kee jaye to vah doosare kisee bhee vyakti ke finger print se nahin khulegee. jab ham kisee computing device ko apane finger print se lock karte hain. to vahaa par hamaare finger ki photo nahin seve hogee balki hamaaree finger ke kuchh point computer kee bhaasha ( binary code) mein save ho jayenge.

iseeliye har ek finger print ka code sabase alag hota hai. aur kisee kee bhee fingerprint ka code dobaara generate nahin kiya ja sakata aur na hee use copy kiya ja sakata.

BIOMETRICS SCANNER KE FAYDE



jaisa kee aapako fingerprint sensor ke baare mein bataaya gaya hai ki sabhee vyaktiyon ke fingerprint alag hote hain isee kaaran koyee bhee vyakti kisee doosare vyakti ke fingerprint ka istemaal karake kisee bhee device ko khol nahin sakata isee tarah doosare biometrics sensor ke bhee bahut saare fayde hote hain jaise ki.

1.isaka sabase bada fayda hee yahee hai kee isake dwaara lock kee gayee device ko sirf vahee vyakti khol sakata hai jisane use lock kiya ho.

2.barometric sensor ke data ko koyee bhee copy nahin kar sakata.

3.barometric sensor dwaara lee gayee jaankaaree ko koyee bhee dobaara nahin bana sakata.

4.biometrics sensor dwaara lock kee gayee device ko hack karke bhee nahin khola ja sakata.


5.biometrics sensar dvaara protected device ek saamanay password dwaara protected device se jyaada secure hotee hai.
