Google har annonceret \u00e5bningen af \u200b\u200bkildekoden til projektet Magika, der er designet til at bestemme typeindhold baseret p\u00e5 analyse af de data, der findes i filen. Magika kan pr\u00e6cist identificere de anvendte programmeringssprog, komprimeringsmetoder, installationspakker, eksekverbare kode, typer markup, lyd-, video-, dokument- og billedformater. Det tilknyttede v\u00e6rkt\u00f8j og den f\u00e6rdige maskinl\u00e6ringsmodel offentligg\u00f8res under Apache 2.0-licensen. <\/p>\n

I mods\u00e6tning til lignende projekter, der bestemmer MIME-typen baseret p\u00e5 indhold, adskiller Magika sig ved at anvende maskinl\u00e6ringsmetoder, h\u00f8j ydeevne og fremragende pr\u00e6cision i bestemmelsen. Modellen er tr\u00e6net ved hj\u00e6lp af Keras-rammen p\u00e5 25 millioner filpr\u00f8ver og underst\u00f8tter genkendelse af 116 datatyper med en pr\u00e6cision p\u00e5 ikke mindre end 99%. Modellen er samlet i ONNX-format og fylder kun 1 MB. Anvendelsen af dybe maskinl\u00e6ringsmetoder har gjort det muligt at \u00f8ge n\u00f8jagtigheden med 50% sammenlignet med det tidligere anvendte system i Google, som er baseret p\u00e5 h\u00e5ndvervede regler.

I Google-systemet anvendes det til klassificering af filer i tjenesterne Gmail, Drive, Code Insight og Safe Browsing under sikkerheds- og overholdelseskontroller. Der arbejdes p\u00e5 at integrere Magika i VirusTotal-platformen som et led i den indledende filtrering af filer, inden der udf\u00f8res specifikke analyser. Den implementerede Magika-konfiguration i Googles infrastruktur muligg\u00f8r scanning af flere millioner filer per sekund og flere hundrede milliarder filer om ugen. Efter modeloploadning er tiden til at generere output 5-6 ms, n\u00e5r den testes p\u00e5 en enkelt CPU-kerne. Tiden til bestemmelse afh\u00e6nger n\u00e6sten ikke af filens st\u00f8rrelse. <\/p>\n

For at aktivere Magika i sine projekter er der udviklet et kommandolinjev\u00e6rkt\u00f8j, en pakke til Python og et JavaScript-bibliotek, der kan fungere i browseren eller i projekter baseret p\u00e5 Node.js. Kommandolinjegr\u00e6nsefladen og API'et underst\u00f8tter k\u00f8rslen af operationer i batch-tilstand, hvilket betyder, at flere filer kan kontrolleres i \u00e9n anmodning. Der er en tilstand for rekursiv scanning af hele indholdet i en mappe og tre forudsigelsesmodes til justering af fejltolerancen (h\u00f8j sikkerhed, middel sikkerhed og bedste g\u00e6t).
