F\u00f6retaget Google har tillk\u00e4nnagivit \u00f6ppnandet av koden f\u00f6r projektet Magika, som \u00e4r avsett f\u00f6r att best\u00e4mma typ av inneh\u00e5ll baserat p\u00e5 analys av data i filen. Magika kan exakt identifiera programmeringsspr\u00e5k, komprimeringsmetoder, installationspaket, k\u00f6rbar kod, typer av markup, ljud-, video-, dokument- och bildformat som anv\u00e4nds i inneh\u00e5llet. Verktygen och den f\u00e4rdiga maskininl\u00e4rningsmodellen kopplade till projektet har publicerats under licensen Apache 2.0. <\/p>\n

Till skillnad fr\u00e5n liknande projekt som best\u00e4mmer MIME-typ utifr\u00e5n inneh\u00e5llet, utm\u00e4rker sig Magika genom att anv\u00e4nda maskininl\u00e4rningsmetoder, h\u00f6g prestanda och exceptionell precision i identifieringen. Modellen har tr\u00e4nats med hj\u00e4lp av Keras-ramverket p\u00e5 25 miljoner exempel p\u00e5 filer och st\u00f6der igenk\u00e4nning av 116 typer data med en noggrannhet p\u00e5 minst 99%. Modellen \u00e4r sammanst\u00e4lld i ONNX-format och har en storlek p\u00e5 bara 1 MB. Anv\u00e4ndningen av metoder f\u00f6r djup maskininl\u00e4rning har \u00f6kat precisionen med 50% j\u00e4mf\u00f6rt med det tidigare systemet som Google anv\u00e4nde, som baserades p\u00e5 manuellt angivna regler.

I Google anv\u00e4nds systemet f\u00f6r klassificering av filer i tj\u00e4nster som Gmail, Drive, Code Insight och Safe Browsing n\u00e4r s\u00e4kerhetskontroller och efterlevnad av tj\u00e4nsternas regler utf\u00f6rs. Det p\u00e5g\u00e5r arbete med att integrera Magika i plattformen VirusTotal som en del av den initiala filtreringen av filer f\u00f6re specifika analysmetoder. Den konfiguration av Magika som har implementerats inom Googles infrastruktur m\u00f6jligg\u00f6r skanning av flera miljoner filer per sekund och flera hundra miljarder filer per vecka. Efter att modellen har laddats upp \u00e4r tiden f\u00f6r att generera ett utdata 5-6 ms vid testning p\u00e5 en CPU-k\u00e4rna. Tiden f\u00f6r identifiering p\u00e5verkas n\u00e4stan inte av filens storlek. <\/p>\n

F\u00f6r att anv\u00e4nda Magika i sina projekt har det f\u00f6rberett ett kommandoradsverktyg, ett paket f\u00f6r Python och ett JavaScript-bibliotek som kan fungera i webbl\u00e4saren eller i projekt baserade p\u00e5 Node.js. Kommandoradsgr\u00e4nssnittet och API:t st\u00f6djer batchoperationer, vilket inneb\u00e4r att det g\u00e5r att kontrollera flera filer med en enda f\u00f6rfr\u00e5gan. Det finns ett l\u00e4ge f\u00f6r rekursiv skanning av hela katalogens inneh\u00e5ll och tre f\u00f6ruts\u00e4gelsel\u00e4gen f\u00f6r att justera felresistensen (h\u00f6g s\u00e4kerhet, medelh\u00f6g s\u00e4kerhet och b\u00e4sta gissning).
