Tvrtka Google poslu\u0161ala je kritike i prekinula promociju API-a Web Environment Integrity, kao i uklonila njegovu eksperimentalnu verziju iz koda Chromium, te prebacila repozitorij sa specifikacijom u arhivski re\u017eim. Ipak, na platformi Android nastavljaju se eksperimentirati s implementacijom sli\u010dnog API-a za verifikaciju korisni\u010dkog okru\u017eenja \u2014 WebView Media Integrity, koji se predstavlja kao pro\u0161irenje temeljeno na Google Mobile Services (GMS). Navodi se da \u0107e API WebView Media Integrity biti ograni\u010den na komponentu WebView i primjene vezane uz obradu multimedijskog sadr\u017eaja, a mo\u017ee se koristiti u mobilnim aplikacijama temeljenim na WebView za streamanje zvuka i videa. Pristup ovom API-u putem preglednika ne planira se. <\/p>\n

API Web Environment Integrity razvijen je kako bi omogu\u0107io vlasnicima web stranica da se uvjere da je klijentsko okru\u017eenje pouzdano u pogledu za\u0161tite korisni\u010dkih podataka, po\u0161tivanja intelektualnog vlasni\u0161tva i interakcije s pravom osobom. Pretpostavljalo se da bi novi API mogao biti tra\u017een u podru\u010djima gdje web stranica treba potvrditi da je na drugoj strani prava osoba i pravo ure\u0111aj, a preglednik nije modificiran i nije zara\u017een zlonamjernim softverom. API se temelji na tehnologiji Play Integrity, koja se ve\u0107 koristi na platformi Android za potvrdu da je zahtjev poslan iz nemodificirane aplikacije, instalirane iz Google Play trgovine te pokrenute na pravom Android ure\u0111aju. <\/p>\n

\u0160to se ti\u010de API-a Web Environment Integrity, mogao se koristiti za filtriranje prometa od botova prilikom prikazivanja oglasa; borbu protiv automatski poslanog spama i manipulacije rangiranjem na dru\u0161tvenim mre\u017eama; otkrivanje manipulacija prilikom prikazivanja za\u0161ti\u0107enog autorskim pravima sadr\u017eaja; borbu protiv prevaranata i la\u017enih korisnika u online igrama; odre\u0111ivanje stvaranja la\u017enih ra\u010duna od strane botova; suprotstavljanje napadima na odabir lozinki; za\u0161titu od phishinga putem zlonamjernih programa koji prenose izlaz na stvarne web stranice. <\/p>\n

Kako bi se potvrdilo okru\u017eenje preglednika u kojem se izvr\u0161ava u\u010ditani JavaScript kod, u API Web Environment Integrity predlo\u017eeno je kori\u0161tenje posebnog tokena koji izdaje tre\u0107a strana (attester), koji je pak mogao biti povezan lancem povjerenja s mehanizmima integriteta na platformi (npr. Google Play). Token se formirao slanjem zahtjeva tre\u0107oj strani server<\/a> za attestation, koja nakon izvr\u0161avanja odre\u0111enih provjera potvr\u0111uje da okru\u017eenje preglednika nije modificirano. Za provjeru autenti\u010dnosti kori\u0161teni su EME dodaci (Encrypted Media Extensions), sli\u010dni onima koji se koriste u DRM-u za dekodiranje medijskog sadr\u017eaja za\u0161ti\u0107enog autorskim pravima. U teoriji, EME nije vezan uz pojedina\u010dne dobavlja\u010de, ali u praksi su ra\u0161irene tri vlasni\u010dke implementacije: Google Widevine (koristi se u Chromeu, Androidu i Firefoxu), Microsoft PlayReady (koristi se u Microsoft Edgeu i Windowsu) i Apple FairPlay (koristi se u Safariju i Appleovim proizvodima). <\/p>\n

Poku\u0161aj implementacije razmatranog API-ja izazvao je zabrinutosti da bi mogao undermandirati otvoreni karakter Web-a i dovesti do pove\u0107ane ovisnosti korisnika o pojedinim dobavlja\u010dima, kao i zna\u010dajno ograni\u010diti mogu\u0107nosti kori\u0161tenja alternativnih preglednika, te ote\u017eati uvo\u0111enje novih preglednika na tr\u017ei\u0161te. Na kraju, korisnici bi mogli postati ovisni o slu\u017ebeno verificiranim preglednicima, bez kojih bi izgubili mogu\u0107nost rada s nekim velikim web stranicama i uslugama.
