Iyo Unredacter toolkit inounzwa, iyo inokutendera iwe kudzoreredza iyo yepakutanga zvinyorwa mushure mekuviga uchishandisa mafirita akavakirwa pixelation. Semuyenzaniso, chirongwa ichi chinogona kushandiswa kuona data rakadzikama uye mapassword akapikiswa mumascreenshots kana snapshots ezvinyorwa. Zvinonzi algorithm yakaitwa muUnredacter inopfuura yaimbowanikwa yakafanana, seDepix, uye yakashandiswawo zvakabudirira kupasa bvunzo yekuziva pixilated zvinyorwa zvakakurudzirwa neJumpsec laboratory. Iyo kodhi yepurogiramu yakanyorwa muTypeScript uye yakagoverwa pasi peGPLv3 rezinesi.
Kudzoreredza zvinyorwa, Unredacter inoshandisa reverse sarudzo nzira, zvichienderana nekuti chikamu chepakutanga pixelated chifananidzo chinofananidzwa nemusiyano wakagadzirwa nekutsvaga nepakati pemabhii pixelated ane akasiyana mashifiti uye akachinja maitiro. Panguva yekutsvaga, sarudzo inonyatsoenderana nechidimbu chepakutanga inosarudzwa zvishoma nezvishoma. Kuti ushande zvinobudirira, unofanirwa kunyatso fungidzira saizi, mhando uye indentation paramita yefonti, pamwe nekuverenga saizi yesero mu pixelation gidhi uye chinzvimbo chegedhi rakavharika pane zvinyorwa (grid offset sarudzo dzinorongwa otomatiki) .
Uyezve, tinogona kucherechedza purojekiti yeDepixHMM, mukati megadziriro iyo shanduro yeDepix inoshandiswa yakagadziriswa, yakashandurirwa kune algorithm yakavakirwa pane yakavanzika Markov modhi, nekuda kwazvaigona kuwedzera kururamisa kwechiratidzo chekuvakazve.
