- Gwema izingxabano zempahla yengqondo (i-IP), ukumangalelwa okubizayo kanye nokuphathwa ikhanda okuvela kubabambi abathi ababazi ukuthi ukudalile ngokungeza ama-watermark abonakalayo kanye / noma angabonakali.
- Ngoba ukusetshenziswa okunwetshiwe kwemithombo yezokuxhumana kusheshise ijubane isithombe / ividiyo engahamba ngayo.

Yini engenziwa ukunqanda ukwebiwa kwezithombe?

Ukungeza i-watermark ekhombisa ngobuqili, noma ngabe isithombe sakho noma ividiyo yakho iya kuphi, ukuthi ingeyakho.

Njalo, i-watermark enegama, i-imeyili noma i-url ukuze indalo yakho ibe nokuxhumana okuthile okubonakalayo nokungabonakali kuwe.

Yini i-watermark edijithali?

Esikhathini esidlule abezindaba babenziwa ngezinto ezibonakalayo. Njengamanje amafayili wesithombe, umsindo nevidiyo akhiwe ngezinombolo. I-watermark yedijithali inezinombolo eziningi ngezindlela ezahlukahlukene ezijojelwe emfanekisweni wesithombe, umsindo kanye / noma amavidiyo ukuwabona. Kunezinhlobo ezi-2 zama-watermark ezisetshenziswa ezithombeni, ama-watermark abonakalayo nangabonakali.

IWatermark yakhelwe ukufaka ama-watermark edijithali nezithombe, izithombe, ihluzo nevidiyo. Lawa ma-watermark abonisa ubunikazi bakho.

Yini i-watermark ebonakalayo?

Ukubeka uphawu esithombeni noma kwidijithali okungeyona ingxenye yesithombe sokuqala noma ividiyo iyi-watermark ebonakalayo. Le watermark iyabonakala esithombeni. Lawa ma-watermark abonakalayo anomsindo omkhulu futhi asobala noma acashile. I-watermark ebonakalayo ingaba umbhalo, ikheli le-imeyili, i-url, ingcaca, ilogo, i-QR-Code, imigqa, izinombolo, amathegi, umbhalo ku-arc, umbhalo ku-banner, vector, kanye / noma emngceleni.

Yini i-watermark engabonakali?

Izinhlobo ezi-2 zama-watermark angabonakali yi-stegomark nemethadatha.

Ama-Stegomark adalwe yiPlum Amazing ukufihla igama, umusho, i-imeyili, i-url noma yiliphi inani elincane lombhalo. I-stegomark ishumekwe esithombeni. I-stegomark izinombolo ezifihlwe yi-algorithm ethile esithombeni. I-stegomark ingaba ne-password noma cha. Ama-stegomark kunzima ukuwasusa esithombeni kunama-watermark abonakalayo. Ama-Stegomark angamelana nokuphindwaphindwa okuphindaphindiwe kwe-jpg. Njengamanje ama-stegomark enzelwe kuphela amafomethi we-jpg. Ama-stegomark okuphathelene nawo adalwe yiPlum Amazing futhi ayingxenye eyodwa yohlelo lokusebenza lwe-iWatermark.

Imethadatha - yesithombe iqoqo ledatha elichaza nokunikeza imininingwane ngamalungelo nokuphathwa kwe- an isithombe. Ivumela imininingwane ukuthi ithuthwe nge isithombe file, ngendlela engaqondakala ngamanye ama-software kanye nabasebenzisi babantu. Ayibonakali kepha ingakhonjiswa ngezinhlobo eziningi zesoftware.

Ingabe iWatermark iwasebenzisa kanjani lawa ma-watermark abonakalayo nangabonakali?

IWatermark ingagxiviza i-watermark ebonakalayo esithombeni noma kuvidiyo eyodwa. Noma ngasikhathi sinye ishumeka ama-watermark amaningi abonakalayo nangabonakali ndawonye ngasikhathi sinye esithombeni noma kuvidiyo. Leli khono elihlukile, ngokwesibonelo, livumela i-iWatermark ukuthi ingeze ilogo ebonakalayo nombhalo okhombisa usuku njenge-watermark ebonakalayo esithombeni. Noma i-iWatermark ingacubungula izithombe eziyi-1000 ezinama-watermark amaningi njenge-logo ebonakalayo ene-

Ayini amathegi e-iWatermark?

Umaki ngamunye uguquguquka kolunye ulwazi oluthile lwemethadatha olufundwa kusithombe ngasinye bese lusetshenziswa njenge-watermark ebonakalayo kuleso sithombe. Esinye isici esiyingqayizivele se-iWatermark.

Kunezigaba ezintathu eziyinhloko zemethadatha:

Incazelo - Imininingwane mayelana nokuqukethwe okubukwayo. Lokhu kungafaka isihloko, amazwibela, amagama angukhiye. Abantu abengeziwe, izindawo, izinkampani, ubuciko noma imikhiqizo ekhonjiswe esithombeni. Lokhu kungenziwa kusetshenziswa umbhalo wamahhala noma amakhodi avela kusilulumagama esilawulwayo noma ezinye izihlonzi.
Amalungelo - ukukhonjwa komdali, imininingwane ye-copyright, amakhredithi namalungelo ayisisekelo kokuqukethwe okubukwayo kufaka phakathi amalungelo emodeli nempahla. Imigomo yokusebenzisa amalungelo eminye imininingwane yokunikeza ukusetshenziswa kwamalayisense.
Ukuphatha - usuku lokudala nendawo, imiyalo yabasebenzisi, okokuhlonza imisebenzi, neminye imininingwane.

Noma yikuphi kwalokhu kungasetshenziswa njengethegi ku-watermark yombhalo esetshenziswayo esithombeni noma ezithombeni.

Sicela uchaze kafushane igama elithi watermarking?

I-Digital Watermarking - inqubo yokushumeka imininingwane efayeleni lemidiya noma elingasetshenziswa ukuqinisekisa ubuqiniso bayo noma ubunikazi babanikazi bayo.
watermark - i-watermark yedijithali ebonakalayo kanye / noma engabonakali ekhomba umnikazi wento ethile yemidiya yedijithali.
I-watermark yedijithali ebonakalayo - imininingwane ibonakala esithombeni. Imvamisa imininingwane ingumbhalo noma ilogo, ekhomba umnikazi wesithombe. Lolo lwazi luhlanganisiwe kulwazi lwesithombe kepha lusabonakala.
I-watermark yedijithali engabonakali - imininingwane efakwe ngaphakathi kwedatha yesithombe yesithombe kepha yakhelwe ukuthi ingatholakali kumbono womuntu ngakho-ke imininingwane efihliwe. I-Steganography isebenzisa inqubo efanayo kepha ngenhloso ehlukile.
Metadata - ulwazi oluchazayo olufakwe ngaphakathi kwanoma yiluphi uhlobo lwefayela. Zonke izinto ezingezansi kwe-EXIF, i-XMP, ne-IPTC yimethadatha efakwa esithombeni. Imethadatha ayishintshi idatha yesithombe yangempela kepha i-piggybacks efayeleni. I-Facebook, iFlickr namanye amapulatifomu wokuxhumana nabantu aku-inthanethi asusa yonke le methadatha (i-EXIF, i-XMP ne-IPTC).
EXIF - I-Exif - Ifomethi yefayela lesithombe eliguquguqukayo (i-Exif) Uhlobo lwemethadatha cishe wonke amakhamera edijithali agcina ngaphakathi kwezithombe. I-EXIF igcina imininingwane engaguquki njengosuku nesikhathi esithathiwe, izilungiselelo zekhamera, isithonjana, izincazelo, i-GPS, ne-copyright. Lolu lwazi aluhloselwe ukuthi lushintshwe kepha lungasuswa ngokuzikhethela ezithombeni. Incazelo isebenzisa amafomethi wefayela we-JPEG, TIFF Rev. 6.0, nama-RIFF WAV, ngokufakwa kwamathegi emethadatha athile. Akusekelwa ku-JPEG 2000, PNG, noma ku-GIF.

I-XMP - I-Extensible Metadata Platform (XMP) wuhlobo oluthile lolimi lwe-markup olwandekayo olusetshenziselwa ukugcina imethadatha ezithombeni zedijithali. I-XMP isetshenzisile i-IPTC. I-XMP yethulwe yi-Adobe ngo-2001. I-Adobe, IPTC, ne-IDEAlliance babambisana ukwethula ngonyaka we-2004 i-IPTC Core Schema ye-XMP, edlulisa amanani emethadatha kusuka ezihlokweni ze-IPTC iye kwiXMP yesimanje futhi eguquguqukayo.

Tag- ucezu olulodwa lwemethadatha. Into ngayinye ngaphakathi kwe-EXIF, i-IPTC, ne-XMP umaki.

Ngisebenzisa i-Lightroom (noma i-Photoshop). Kungani kufanele ngisebenzise iWatermark?

I-iWatermark ihlinzeka ngamathuluzi okubukisa awatholakali eLightroom. Isibonelo, i-watermark yombhalo e-Lightroom ngosayizi owodwa ongaguquki ngamaphikseli ukuze i-watermark yehluke ngokuya ngesinqumo sezithombe ezenziwa i-watermark. Ngenkathi i-iWatermark inama-watermark wombhalo azikala ngokulingana ngokuya ngesisombululo noma i-portrait / lanscape. I-Lightroom isebenzisa amaphikseli ukuthola indawo ye-watermark kanti i-iWatermark ibeka i-watermark ngokulingana ngokusekelwe ku-esolution noma ku-portrait / lanscape. Lokho kusho ukuthi uma uthengisa iqoqo lezithombe zezinqumo ezihlukile kanye / noma i-landscape noma i-portrait orientation i-iWatermark ingaba ne-watermark egcina ukubukeka / ubunikazi obufanayo kuzo zonke lezi zinhlobo zezithombe. I-iWatermark nayo inezinketho zokungalingisi. Lokhu ngumehluko emi-2 emikhulu.

Ngabe imethadatha esesithombeni ingasetshenziselwa ukunamathisela isithombe?

Yebo! Lokhu kubizwa ngama-iWatermark Tags. Amathegi e-iWatermark angenza imethadatha engabonakali ibe yi-watermark ebonakalayo. Isibonelo kunemethadatha efakwa wonke amakhamera esithombeni segama lekhamera, uhlobo lwamalensi, usuku nesikhathi sesithombe, indawo (nge-GPS) nezinye eziningi. Ku-watermark yombhalo ukhetha amathegi wanoma yikuphi kwalokhu, okufana 'negama lekhamera', bese leyo watermark yombhalo yenza lokho kubonakale lapho ufuna khona esithombeni, ngosayizi, umbala, ifonti, njll. Manje, ake sithi uthole okufakiwe okungu-2356 komncintiswano wezithombe. Udinga ukubeka igama lekhamera nosuku nesikhathi sesithombe kulowo nalowo. Bese usebenzisa iWatermark uqoqe ngokuzenzakalela zonke izithombe ezingama-2356 ngasikhathi sinye, isithombe ngasinye sizokhombisa igama lekhamera nesikhathi nesikhathi nosuku, ngoba iWatermark ifunda futhi isebenzise imethadatha efanelekile yewatsermark ngayinye, bese isibeka kuleso sithombe ezansi kwesokudla ifonti yakho nosayizi wefonti oyithandayo. Konke ngaphandle kokuthi uphakamise umunwe noma uzame ukuthola konke lokho. ISINDISI sesikhathi esikhulu.

Ngabe iWatermark ingabhala imethadatha esithombeni?

I-iWatermark ingafunda futhi ibhale imethadatha ngezindlela ezahlukahlukene ezikhethekile ezifaka noma eziguqula imethadatha esithombeni. Isibonelo uma usebenza kwaReuters noma eNew York Times Newspaper njengomthwebuli zithombe mhlawumbe udinga ukufaka imethadatha ezithombeni zakho. Bangakucela ukuthi ungeze igama lakho, ilungelo lobunikazi, indawo, njll. Konke lokhu kungangezwa ngokusebenzisa i-iWatermark metadata watermark. Uma usuwenzile iWatermark metadata watermark ke, ngokuzayo, ngokuchofoza ungayikhetha bese uyisebenzisa ezithombeni ezi-1 noma ezingama-221,675 ngokudubula okukodwa. Kuyasiza kakhulu ukwakha wonke ama-watermark wamamethadatha owadingayo ngakho-ke aseduze futhi ungawasebenzisa lapho kudingeka. Ayikho enye i-watermark yohlelo lokusebenza efana nale. I-iWatermark ihlukile futhi ukuphela kohlelo lokusebenza oludala amasethadatha futhi engazisebenzisa ngokuzenzakalela ezithombeni njengoba kudingeka.

Kungani kufanele ngibukele izithombe engizibeke ku-Facebook, Twitter, Instagram, Tumblr, njll.

Umbuzo omuhle kakhulu! Ngoba zonke lezo zinsizakalo zisusa imethadatha yakho futhi ngaleso sikhathi akusekho imininingwane ebopha leso sithombe kuwe. Abantu bangavele bahudulele isithombe sakho kudeskithophu yabo bese babelana nabanye kuze kungabikho ukuxhumana kuwe futhi kungabikho lwazi efayeleni elithi ulidalile noma ungumnikazi walo. Kulokhu i-watermark ebonakalayo iqinisekisa ukuthi wonke umuntu ucacelwa iqiniso lokuthi isithombe siyi-IP yakho (impahla ebhaliwe). Awusoze wazi ukuthi isithombe osithathile sizoqala ukusabalala. Thepha lapha ukuze uthole izibonelo ezithile zokwebiwa kwezithombe ezisakazeke kakhulu.

Ingabe i-Photo Piracy noma i-Photo Theft?

I-Photo Piracy ivame ukubhekwa njengabantu abasemithonjeni yezokuxhumana ababambe isithombe sakho basisebenzise ngaphandle kwemvume kodwa ngokungasisebenzisi okokuhweba.

Ukwebiwa kwezithombe kulapho inkampani isebenzisa isithombe sakho ngezinjongo zokuhweba. Kulokhu unezizathu ezithile zokubamangalela njengomdali wesithombe noma ividiyo.

Kungenzeka yini ukumangalela isela lezithombe?

Yebo, ilungelo lobunikazi yilungelo lesakhiwo. Ngaphansi kwe-Federal Copyright Act ka-1976, izithombe zivikelwe yi-copyright kusukela lapho uthatha isithombe sakho, zivikelwa ngumthetho. Awudingi ngisho nokuwabhalisa noma uwaveze njenge-copyright; bangabakho.

Uma inkampani ethile noma umuntu othile elanda izithombe zakho futhi azibonise esidlangalaleni. Bazisebenzisela inhloso yabo. Ukuqhubeka uma bekuhambisa kwabanye, noma ukudala imisebenzi evela kubo kwephula ilungelo lakho lobunikazi uma kwenziwa ngaphandle kokuxhumana nawe futhi uthole imvume yakho.

Lapho isithombe sakho noma ividiyo yebiwe lapho njengomthwebuli zithombe ungalahlekelwa yimali engenayo nokwaziwa. Kungenzeka futhi ukuthi isithunzi sakho singahlupheka uma kungacaci ukuthi ngubani owebile ini. Ijaji lizibhekela zonke lezi zinto lapho likhipha isinqumo.
