Locks tau hloov pauv ntau pua xyoo, tab sis kev tawm tsam los ua kom pom kev sib npaug ntawm kev ruaj ntseg, nqi thiab yooj yim yog tas mus li. Txij li cov hnub thaum Maharajahs ntawm Is Nrias teb khaws cia lawv cov khoom muaj nqis rau cov kab mob moats (kev nkag mus tau tsuas yog ua tau los ntawm kev tua tsiaj txhu nyob ib puag ncig lossis siv tshuaj crocodiles) rau lub hnub nyoog tam sim no.
Peb paub tias cov ntoo ntoo tau siv plaub txhiab xyoo dhau los, qhov qub pom tau muaj los ntawm ib lub tsev huab tais hauv Ninevenh (tam sim no Iraq). Cov yuam sij ntawm lub sijhawm no tau loj heev uas ib tug qhev tau yuav tsum nqa ib - tsis yooj yim dua li cov crocs.
Cov Loos sib koom ua ke Iyiv, Greek, thiab kev txhim kho Suav thiab ua cov hlau xauv dav muaj. Vim tias Roman Togaus tsis muaj hnab looj qaws tsis muaj me me txaus kom tau koom rau hauv cov ntiv tes nplhaib tau tsim.
Kev txhim kho cov xauv rau hauv cov nruab nrab hnub nyoog tau meej pem rau cov tshuaj pleev ib ce. Locksmithing tau txiav txim los ntawm guilds uas feem ntau ua ke ntawm cov khoom siv phem tshaj plaws los ntawm kev tawm tshiab, cuav cov keyholes thiab zais cov xauv tiag tiag rau cov ntawv qaij.
Lub sij hawm no sib xyaw cov xauv tau paub thiab siv tab sis tuaj yeem yooj yim swb los ntawm "xav."
Hauv 1778 Robert Barron ntawm lub ntsuas phoo uas tau tsim lub ntsuas phoo, qhov no tau muab kev tiv thaiv tiag tiag rau thawj zaug thiab siv nyob rau lub hnub nyoog tsim muaj.
Hauv 1784, Yauxej Bamah pom nyob hauv nws lub khw London lub cim uas muaj rau xyoo 180) rau ib tus neeg tuaj yeem tau txais txiaj ntsig, thiab tom qab 51 teev ntawm kev siv zog.
Linus Yale Jr. Precision ua ke ntsuas phoo hloov pauv no, yaleâ's "khawv koob txhab nyiaj lock" tawm hauv 1861.
1873, James sargent, ntawm rochester, NY tau tsim lub sijhawm xauv nws yog qhov tsim nyog los paub ua ke, thiab tseem lub sijhawm qhib thaum qhib lub xauv tau ua tau.
Tam sim no yog lub sijhawm ntawm kev ua ntej thev naus laus zis zoo ib yam li 18th caug xyoo, peb lub kiv puag ncig, yog nyob rau hauv electronics ntau dua li kev siv tshuab.
Hloov hauv tus nqi
Nyob rau xyoo pua cuaj caum nws yog kub thiab pob zeb diamond uas yuav tsum tau tiv thaiv kawg; Niaj hnub no cov kub yog cov ntaub ntawv, niaj hnub no cov pob zeb diamond yog neeg nyob. Cov hluav taws hluav taws xob tau coj qhov chaw ntawm hluav taws-ntawv pov thawj kev nyab xeeb. Nyuaj disks tau hloov bullion.
Cov ntaub ntawv, xws li cov ntaub ntawv kho mob uas, 25 xyoos dhau los, raug kho kom muaj nqis ntau dua li cov ntawv lawv tau sau tseg thiab tsis pub lwm tus paub tsis pub lwm tus paub. Cov tub sab ua rau lawv cov tsiaj txhu los ntawm nyiag cov cim, password thiab lwm yam rau cov txhab nyiaj hauv tuam txhab nyiaj thiab credit. Yog tias on-line tus neeg muag khoom tsis tuaj yeem lav tias kev nyab xeeb uas lawv yuav poob lawv cov neeg siv khoom.
Hauv "sab hnub poob," raws li lub neej tau yooj yim dua, tus nqi peb muab rau peb kev tu siab dhau los poob 5 lub dav hlau nyob rau hauv tag nrho kev ua tsov ua rog; Piv nrog rau tsuas yog 60 xyoo dhau los thaum lub teeb meem poob ntawm 5 lub dav hlau ({{txiv neej) hauv ib qho 100 BOMBER RAID yuav tsis tau ua rau sab pem hauv ntej. Nrog rau qhov nce ntxiv no (pom) tus nqi tau tuaj yeem ua kom muaj kev pheej hmoo ntxiv ntawm tus nqi ntxiv thiab tsis yooj yim hauv tshav dav hlau.
Yuam sij
Ntau lub sij hawm tsuas yog cov tsos ntawm lub xauv yog txaus kom deter tus tub sab kheej. Hauv lwm qhov xwm txheej nws yog ib qho tseem ceeb uas lub qhov rooj tab tom tau xauv. Qee zaum nws yog ib qho tseem ceeb uas lub qhov rooj pom tau xauv. Yuav kom ua tiav cov xauv no tuaj yeem tsim los khaws tus yuam sij thaum xauv, lossis tus yuam sij tuaj yeem siv tau rau qhov pom tseeb "qhib" txoj haujlwm.
99% ntawm tag nrho cov xauv tau ua haujlwm los ntawm cov yuam sij sib xyaw. Yog li pom tseeb tias lawv ua haujlwm zoo heev thiab raug nqi tau zoo nyob rau hauv feem ntau cov ntawv thov. Cov ntsiab lus tseem ceeb yuav tsum muaj kev txwv raws li tuaj yeem pom hauv cov rooj sib txuas 1.
Muaj cov yuam sij siab heev yog muaj uas nyuaj rau kev luam nrog hloov chaw muaj tsuas yog los ntawm cov khw. Nov yog tus nqi tseem ceeb ntawm cov ntaub ntawv khaws cia thiab tsis yooj yim xws li nyiaj. Qhov nyuaj ntawm tus yuam sij tsis muaj kev tiv thaiv kev tawm tsam tub sab.
Tag nrho lwm lwm tus yuam sij yog qhov yooj yim rau daim ntawv (txawm tias thaum twg ntaus thwj "tsis txhob theej").
Daim duab ntawm lub tsev loj cuj nrog lub nplhaib loj ntawm cov yuam sij ntawm cov yuam sij, tab sis nws muaj qhov tsis yooj yim thiab hnyav tsis zoo li yuav ploj thiab nws cov tub sab nyiag tau pom tseeb. Nyob rau hauv feem ntau colloform cov chaw thiab cov ntaub ntawv cov chaw nruab nrab yog siv los txhim kho txhua lub qhov rooj kom yooj yim los ntawm kev tso cai rau ib qho system uas tau tso cai rau tsuas yog ib qho, lossis ib qho teeb. Qhov kev tshem tawm no tshem tawm qhov kev xav tau hais tias tus txiv neej txij nkawm los nqa cov yuam sij ntau. Raws li ib txwm muaj kev lag luam tawm: tus tswv yog muaj nqis heev.
Kev txhim kho kev txhim kho tsis ntev los no yog ib qho kev ua haujlwm los ntawm kev sib xyaw nrog tus tseem ceeb tshaj; Qhov kev ua haujlwm no zoo li lub kaw lus zoo li cov kab ke, tab sis locks tuaj yeem yooj yim "rov teeb" hauv feeb, raws li tau hais, lossis cov neeg ua haujlwm tuaj thiab mus.
Nws tsis yog ib txwm tsim nyog los siv ntau ntawm cov qauv tseem ceeb yog tias muaj kev soj ntsuam ib qho; Ib tug neeg sim 25 lub ntsiab ua ntej ib qho qhib yuav tsis ua tiav.
Txhua qhov system uas yuav tsum muaj cov yuam sij muaj teeb meem thaum tus yuam sij ploj mus, thawj qhov nyuaj yog rau tus neeg muaj lub luag haujlwm kom paub txog kev poob. Kev txiav txim siab yuav tsum yog ua raws li qhov tseem ceeb ntawm tus yuam sij poob rau hauv nefarious txhais tes thiab los ntawm qhov kev txiav txim siab rov ua ib qho tseem ceeb, lossis txhua yam, xauv yog cov cai. Cov kev siv nyiaj thiab sijhawm siv ua qhov no, tshwj xeeb yog tias nws yog tus tswv tseem ceeb uas tau mus ua yuam kev, qhia tias nws yuav tsis tiav. The property at risk if a key is compromised often does not belong to the holder of a master key, this presents a conflict of interests and is a good argument for lessees to demand a system that can be "re-keyed" easily and inexpensively.
Qhov teeb meem tsis zoo yog thaum tus yuam sij tau theej, tsuas yog tus neeg ua haujlwm uas tsis raug cai) Leej twg tsis tuaj yeem paub txog kev ua txhaum kev cai no. Ib zaug ntxiv yog tias "re-keying" yog yooj yim nws tuaj yeem ua txhua zaus cov neeg ua haujlwm tawm.
Raws li qhov kev xav tau rau cov qauv zoo tau nce thiab cov tuam txhab siv hluav taws xob tau tsis lees paub ntau dua thiab ntau lub koom haum tau txiav txim siab "kev hloov hluav taws xob."
Hauv cov cuab yeej ntawm cov neeg rau zaub mov
Nrog rau cov txiaj ntsig ntxiv ntawm cov ntaub ntawv ntau kev nyab xeeb tau tsom rau lub khoos phis tawm hauv computer, ob qho tib si los ntawm cov khoom siv hluav taws xob thiab lub cev. Lub tshuab hluav taws xob hluav taws xob txee kev ruaj ntseg system xws li emkaÂ's modular system tuaj yeem teeb tsa hauv kev ruaj ntseg thiab kev yooj yim hauv kev ua ke tsim nyog tshaj plaws.
Lub chaw teeb tsa txhab nyiaj raug lossis lub chaw collopation yuav muaj, tej zaum, 250 tus neeg rau zaub mov xwm txheej txhua tus nrog ib qho, ob lossis tom qab. Cov ntaub thaiv yog teeb tsa hauv cov tsev txhab nyiaj hauv chav nyab xeeb. Chav tsev ib txwm nkag los ntawm daim npav ID / cov npav sib thooj. Ob peb ntawm cov servers yuav tsum tau xauj tawm rau ntau tus neeg tuag, lawv thiab lawv cov neeg tu lawv yuav tsum tau txais ib lub sijhawm. Kev tswj hwm ntawm lub tsev kuj xav tau nkag thiab muaj peev xwm xauv tawm tus neeg tsawg.
