Anonimiseer in LibreOffice Writer, Calc & Impress
Oopbroncoffice-suite, enterprise-grade privaatheid. Ons inheemse LibreOffice-uitbreiding bring PII-opsporing en anonimisering na Writer, Calc en Impress.
Werk oor LibreOffice
Een uitbreiding vir Writer-dokumente, Calc-sigblaaie en Impress-aanbiedings. Volledige kantelbalk-integrasie met formaatbehoud.
LibreOffice Writer
Documents, contracts, reports — with full format preservation
LibreOffice Calc
Spreadsheets, data tables — cell-based processing
LibreOffice Impress
Presentations, slides — text object extraction
Belangrikste Voordele
Werk In-plek
Geen kopie-plak nodig. Anonimiseer direk in LibreOffice via die geïntegreerde kantelbalk-paneel.
Formaatbehoud
Writer-dokumente hou alle formatering - vetdruk, skuinsdruk, lettertipes, kleure, paragraafstyle. Slegs teksinhoud verander.
Veilige Verwerking
Dokumente bly op jou masjien. Slegs teks word na ons versleutelde API gestuur vir entiteitsopsporing en anonimisering.
Nul-kennis Aanmelding
Jou wagwoord verlaat nooit jou toestel. Opsionele ZK-outentisering met XChaCha20-Poly1305-versleuteling.

PII-opsporing
- Spoor 285+ entiteitstipes op (name, e-posse, SSN, IBAN, krediekkaarte, ens.)
- Hibriede opsporing: regex-patrone + NLP vir maksimale akkuraatheid
- Meertalige ondersteuning (48 tale insluitend RTL)
- Pasgemaakte entiteitsherkenning met regex of ontkennende lyste
Anonimiseringsmetodes
- 5 metodes: Vervang, Masker, Swart, Hash (SHA-256), Versleutel (AES-256-GCM)
- Omkeerbare versleuteling met ZK-verpakte persoonlike sleutels
- Per-entiteit-operateur-konfigurasie (verskillende metodes per entiteitstipe)
- Gesegmenteerde verwerking (8 000 karakterbrokke) vir groot dokumente
Gevorderde Kenmerke
Voorvertoningsdialoog
Beoordeel tot 50 bespeurde entiteite voordat u anonimiseer. Kies, verkies af, of verander metodes per entiteit voordat u engageer.
Voorstellings
Stoor en hergebruik anonimiseringsinstellings. Voorstellings word sinchroniseer oor toestelle insluitend entiteitstipes, metodes en score-drempels.
Omkeerbare Versleuteling
Versleutel PII met AES-256-GCM en dekripteer later. ZK-verpakte sleutels oplaai outomaties van jou rekening met sessie-volharding.
Per-entiteit Operateurs
Konfigureer verskillende anonimiseringsmetodes vir elke entiteitstipe. Hash-name, versleutel e-posse, masker telefoonnommers - alles in een deurloper.
Sinchronisering Tussen Toestelle
Voorstellings, pasgemaakte entiteite en versleutelingsleutels sinchroniseer oor al jou toestelle elke 5 minute via jou rekening.
48 Tale
Volledige meertalige ondersteuning insluitend Arabies, Hebreeus, Sjinees, Japannees en Koreaans. RTL-tale volledig ondersteun.
Dokumentondersteuning
Writer
Volledige teksekstraksie, keusgebaseerde verwerking en formaatbehoud (7 lettertipe- + 4 paragraafeienskappe).
Calc
Sel-gebaseerde verwerking met tab-skeie teksekstraksie. Verwerk hele velle of geselekteerde reekse.
Impress
Gly-teks-objek-verwerking. Ekstraheer en anonimiseer teks uit alle vorms en teksbokse oor glye.

Gereeld Gestelde Vrae
Watter LibreOffice-toepassings word ondersteun?
Writer, Calc en Impress. Writer het volle kenmerkundersteuning insluitend formaatbehoud. Calc verwerk selle as tab-skeie teks. Impress ekstraheer teks uit gly-objekte.
Hoe installeer ek die uitbreiding?
Laai die .oxt-lêer af en dubbelklik dit, of gaan na Gereedskap > Uitbreidings-bestuurder > Voeg in LibreOffice in. Of voer python3 build.py --install uit vanuit die bronaddres.
Behoud dit dokumentformattering?
Ja, in Writer-dokumente. Die uitbreiding behou 7 fonteienskappe (vet, skuins, onderstreep, deurhaling, fontnaam, grootte, kleur) en 4 paragraafeienskappe (belyning, eerste-lyn inspring, linkermarges, regtermarges).
Wat is Nul-kennis outentisering?
ZK-outentisering beteken jou wagwoord verlaat nooit jou toestel. In plaas daarvan word 'n kriptografiese bewys na ons bediener gestuur met XChaCha20-Poly1305-versleuteling en Argon2id-sleutelafleiding. Opsioneel - standaard e-pos/wagwoord-aanmelding is ook beskikbaar.
Kan ek dit sonder internet gebruik?
Nee. Die uitbreiding vereis 'n internetverbinding om met die anonym.legal API te kommunikeer vir entiteitsopsporing en anonimisering. Vir sonder-internetgebruik, sien anonym.plus.

E-discovery productions and GDPR DSARs span PDFs, Word docs, Excel, and JSON exports. Using different tools for each format creates consistency gaps that.

The DOJ Epstein files, the Manafort case, and NSA leaks all share the same failure: cosmetic redaction that leaves underlying text extractable.
Legal PII: Privilege Detection
Case reference numbers, bar admission numbers, court docket numbers, and client matter IDs are legally sensitive identifiers that standard PII tools miss.

Words from our team
We started this work after a lunch about cookies.
One friend kept getting odd ads on her phone.
We asked why a court file leaked through a draft.
We sketched the first build on a napkin that week.
By month three we had a tiny demo for a friend.
She used it on her first case the next day.
Common questions we hear
Can the tool read scanned PDFs? Yes, with OCR.
Does it work on long files? Yes, in small chunks.
Can I roll my own rule set? Yes, save it as a preset.
Does it run offline? The desktop build runs offline.
Do you keep my files? No, the cloud build wipes after each run.
Will it learn from my work? No, we never train on inputs.
A short tour of the workflow
Upload a file or paste a snippet of prose.
Pick the entities you want gone from the draft.
Choose a method: replace, mask, hash, encrypt, or redact.
Press run and watch the side panel show each hit.
Skim the result and tweak any rule that misfired.
Save the cleaned file or send it to a teammate.
