Compania Google a anun\u021bat deschiderea codului surs\u0103 al proiectului Magika, destinat identific\u0103rii tipului de con\u021binut pe baza analizei datelor existente \u00een fi\u0219ier. Magika poate determina cu acurate\u021be limbajele de programare utilizate \u00een con\u021binut, metodele de comprimare, pachetele de instalare, codul executabil, tipurile de marcare, formatele audio, video, documente \u0219i imagini. Instrumentele legate de proiect \u0219i modelul de \u00eenv\u0103\u021bare automat\u0103 sunt publicate sub licen\u021ba Apache 2.0. <\/p>\n

Spre deosebire de proiectele similare care determin\u0103 tipul MIME \u00een func\u021bie de con\u021binut, Magika se distinge prin aplicarea metodelor de \u00eenv\u0103\u021bare automat\u0103, performan\u021ba \u00eenalt\u0103 \u0219i precizia excelent\u0103 a identific\u0103rii. Modelul a fost antrenat folosind cadrul Keras pe 25 de milioane de exemple de fi\u0219iere \u0219i suport\u0103 recunoa\u0219terea a 116 tipuri de date cu o precizie de cel pu\u021bin 99%. Modelul este compactat \u00een format ONNX \u0219i are o dimensiune de doar 1 MB. Utilizarea metodelor de \u00eenv\u0103\u021bare profund\u0103 a crescut cu 50% precizia identific\u0103rii comparativ cu sistemul anterior utilizat de Google, bazat pe reguli specificate manual.

\"Google<\/center> <\/p>\n

\u00cen Google, sistemul este folosit pentru clasificarea fi\u0219ierelor \u00een serviciile Gmail, Drive, Code Insight \u0219i Safe Browsing \u00een timpul verific\u0103rilor de securitate \u0219i conformitate cu regulile serviciilor. Se lucreaz\u0103 la integrarea Magika \u00een platforma VirusTotal ca un element pentru filtrarea ini\u021bial\u0103 a fi\u0219ierelor \u00eenainte de a efectua analizele specifice. Configura\u021bia implementat\u0103 \u00een infrastructura Google asigur\u0103 scanarea a mai multor milioane de fi\u0219iere pe secund\u0103 \u0219i a sute de miliarde de fi\u0219iere pe s\u0103pt\u0103m\u00e2n\u0103. Dup\u0103 \u00eenc\u0103rcarea modelului, timpul necesar pentru generarea unui rezultat este de 5-6 ms c\u00e2nd este testat pe un singur nucleu CPU. Timpul de identificare nu depinde aproape deloc de dimensiunea fi\u0219ierului. <\/p>\n

Pentru a utiliza Magika \u00een proiectele sale, au fost preg\u0103tite o unealt\u0103 de linie de comand\u0103, un pachet pentru Python \u0219i o bibliotec\u0103 JavaScript capabil\u0103 s\u0103 func\u021bioneze \u00een browser sau \u00een proiectele bazate pe Node.js. Interfa\u021ba de linie de comand\u0103 \u0219i API-ul suport\u0103 executarea opera\u021biunilor \u00een mod batch, adic\u0103 permit verificarea mai multor fi\u0219iere \u00eentr-o singur\u0103 cerere. Exist\u0103 un mod de scanare recursiv\u0103 a \u00eentregului con\u021binut al directorului \u0219i trei moduri de prognoz\u0103 pentru a ajusta rezisten\u021ba la erori (\u00eenalt\u0103 \u00eencredere, medie \u00eencredere \u0219i cea mai bun\u0103 estimare).
