Isiginesha Yakho Yedijithali, Esenziwe lula.

PDF Digital Blockchain Isiginesha

Sinikeza indlela yesimanjemanje, eqinile yokusayina imibhalo ye-PDF kusetshenziswa ubuchwepheshe be-blockchain. Isiginesha ngayinye ibethelwe, igxivizwe isikhathi, futhi ibhalwe ku-blockchain, idala irekhodi elingunaphakade neliqinisekisekayo elingakwazi ukuguqulwa. Kungakhathaliseki ukuthi usayina inkontileka eyodwa noma uphatha izivumelwano zamaqembu amaningi, isistimu yethu iqinisekisa ukuthi isiginesha ngayinye iyiqiniso, isemthethweni, futhi kulula ukuyiqinisekisa.

I-ID ye-KYC nokuqinisekiswa kwendawo

Qinisekisa ubunikazi bekhasimende ngokuhlolwa kwedokhumenti ye-ID evikelekile, ukuthwebula indawo ebukhoma, kanye nobufakazi obulungele ukuhlolwa.

Ingxoxo yevidiyo ozikhethela yona inikeza ubukhona besikhathi sangempela nokuqinisekiswa kokuphila, kanye nemibhalo ebhaliwe nama-artifact agcinelwe ukuthotshelwa.

Vikela ukugcinwa kwamadokhumenti e-Amazon S3 Bucket

I-Amazon Simple Storage Service (S3) iyisevisi ehlala isikhathi eside, eyingozi yokugcina izinto. I-XSigi isebenzisa amabhakede e-S3 ukuze igcine ngokuvikelekile amadokhumenti akho abethelwe ngokulawulwa kokufinyelela okuhlaziywe kahle, ukubethela kohlangothi lweseva noma uhlangothi lweklayenti, inguqulo, nezinqubomgomo zomjikelezo wempilo ukuze kugcinwe okudingayo futhi uhlanze ongakufuni.

TEXT Ukubethela

Sebenzisa ifomethi entsha ye-XSigi Envelope v1 yokubethela umbhalo uhlanganise amasu amathathu anamandla e-cryptographic:

• Isiginesha ye-Ed25519 — iqinisekisa ubuqiniso nobuqotho, ivumela abamukeli ukuthi baqinisekise umthumeli.
• Amabhokisi avaliwe e-X25519 — ahlinzeka ngobumfihlo ukuze kube kuphela umamukeli ohlosiwe ongasusa ukubhala.
• I-JSON ehlomile — isonga idatha ebethelwe nge-JSON efundekayo ukuze kube lula ukuhamba nokushumeka.

Ndawonye, baletha isiqukathi sombhalo esiphathekayo, esiqinisekisekayo, nesivikelekile esilungele ukugeleza komsebenzi kwesimanjemanje.

I-CRYSTALS-Kyber: Ukhiye Wokubethela Kwangemva Kwequantum

Sebenzisa okusekelwe ku-lattice, okukhethwe yi-NIST-CRYSTALS-Kyber ukuze uthole amadokhumenti afaka ukhiye angamelana nenani asheshayo nezimfihlo ngokumelene nokuhlaselwa okuzayo.

• Ukushintshanisa ngokhiye we-quantum
• Umkhawulokudonsa ophansi, ukusebenza okuphezulu
• Ukugeleza komsebenzi okuvikelekile kobufakazi besikhathi esizayo

Ihlanganiswe epayipini lokubethela le-XSigi ukuze kuvikelwe idatha namuhla—futhi nangemva kokufika kwamakhompyutha wenani elikhulu.

I-Watermark Engabonakali (isekelwe ku-DCT)

Vikela izithombe zakho nge-watermark engabonakali, ekwazi ukumelana nokuphazamiseka esebenzisa ubuchwepheshe be-Discrete Cosine Transform (DCT). Ngokungafani nokumbondelana okubonakalayo, i-watermark esekelwe ku-DCT ifihliwe ngaphakathi kwesizinda se-frequency yesithombe, isenze singabonakali ngeso lomuntu kodwa sibonakale ngokuthembekile ngamathuluzi alungile.

Ilungele abathwebuli bezithombe, abaklami, namabhizinisi adinga ukufakazela ubunikazi ngaphandle kokushintsha ikhwalithi yokubuka.

I-ZIP Encryption

Vikela amafayela akho ngokubethela kwesizukulwane esilandelayo okuhlanganisa ubuchwepheshe bokhiye basesidlangalaleni/abayimfihlo kanye ne-algorithm ye-ChaCha20-Poly1305, eletha kokubili isivinini nokuvikeleka okungayekethisi. Le ndlela ethuthukisiwe iqinisekisa ukuthi umamukeli ohlosiwe kuphela ongavula okuqukethwe kwefayela lakho le-ZIP, kuyilapho yonke imizamo yokuphazamisa ibonakala ngokushesha.
