Rozsirenie LibreOffice na anonymizaciu PII

LibreOffice ma odhadovanych 200 miliónov pouzivatelov po celom svete. Spolieha sa na ne vláda, skoly a firmy. Mnoge pouzivaju LibreOffice, aby sa vyhli nakladnym softverovym licenciám. Dovtedy vsak pouzivatelia nemali vbudovany nastroj na vyhladavanie a odstranovanie osobnych udajov zo svojich suborov.

Stare riesenie bolo bolestive. Skopirujte text do webovej aplikacie. Anonymizujte ho. Vlozte ho spat. To nici formatovanie. Rozbija tabulky, styly a rozlozenie. Pre zlozite dokumenty Writer to nefunguje.

Rozsirenie anonym.legal toto riesí. Funguje priamo v aplikacii. Deteguje viac ako 285 typov entit v Writer, Calc a Impress.

Nainstalovanie za menej ako dve minuty

Rozsirenie sa dodáva ako subor .oxt. Toto je standardny format pre vsetky rozsirenia.

Rychla instalacia:

  1. Stiahnite .oxt z anonym.legal/api/download/libreoffice
  2. Dvakrat kliknite na subor
  3. Potvrdre vyzvu
  4. Restartujte

Rucna instalacia:

  1. Otvorte aplikaciu
  2. Prejdite na Nastroje, potom Spravca rozsireni
  3. Kliknite Pridat, potom vyberte subor .oxt
  4. Restartujte

Po restartovani sa postranný panel anonym.legal objavuje pod Zobrazit, potom Postranný panel. Prihlaste sa na zaciatok prace.

Ako funguje detekcia

Dva motory bezat spolu na vyhladanie PII.

MotorNajdeSpolahlivos
RegexEmaily, SSN, IBAN, kreditne karty, telefonne cisla1,0
spaCy NLPMena, organizacie, lokality0,85+

Detekcia prebieha na API anonym.legal. Text ide na certifikovane servery v Nemecku. Servery maju status ISO 27001. Vysledky sa vracia do rozsirenia. Žiadne subory dokumentov sa neposielajú. Prenasa sa iba text.

Co robi kazda aplikacia:

  • Writer: Extrahuje uplny text alebo iba vyber
  • Calc: Cita bunky ako hodnoty oddelene tabulatorom vo vsetkych listoch
  • Impress: Cita textove objekty zo vsetkych snimok

Pat metod anonymizacie

MetodaPrikladReverzibilna?Trieda GDPR
NahraditJán Novak -> PERSONNieAnonymizacia (Recital 26)
Maskovatjan@priklad.sk -> j***@p***.skNieAnonymizacia
Redaktovat555-0123 -> [REDACTED]NieAnonymizacia
Hash (SHA-256/512)SSN -> a1b2c3d4...NiePseudonymizacia (WP29)
Sifrovat (AES-256-GCM)Meno -> ENC:xyz...AnoPseudonymizacia (Cl. 4(5))

Metody môzete kombinovat v jednom prechode. Nahradte mena, ale sifrujte emaily. Kazdy typ entity ma vlastné pravidlo.

Format zostáva v poriadku vo Writeri

Toto je hlavna vyhoda oproti kopírovaní a vkladaniu. Rozsirenie zachovava vsetko formatovanie pri nahrazovani textu.

Sedem zachovanych vlastnosti fontu:

  • Rodina, velkost, tucnost, kurziva, farba, podciarknutie, preskrtnutie

Styri zachovane vlastnosti odseku:

  • Zarovnanie, zarucenie prvého riadku, lavy okraj, pravy okraj

"Ján Novak" v tucnej 14pt Times New Roman sa stane "PERSON" v rovnakom style. Tabulky, hlavicky a paticka zostanu neporušene. Rozsirenie pracuje vnútri modelu dokumentu. Nevyvaza a znovu neimportuje text.

Poznamka: Sledovanie formatu sa tyka iba Writera. Calc a Impress pouzivaju iba nahradenie na urovni textu.

Kontrola pred pouzitim

Nahiad zobrazuje az 50 najdenych entit. Kazdy riadok ukazuje:

  • Typ entity (PERSON, EMAIL_ADDRESS, PHONE_NUMBER atd.)
  • Povodny text
  • Navrhované nahradenie
  • Skóre spolahlivos

Prijmite alebo odmietnite kazdu entitu jeden po druhom. Vyberte vsetky alebo vymažte vsetky jednym kliknutim. Nic sa nezmeni, kym nekliknete Aplikovat. Vo Writeri Ctrl+Z zruší poslednu operaciu.

Nastavenia sa synchronizuju napriec zariadeniami

Ulozte nastavenia ako nastavenie. Vyberte typy entit, metody a prahove hodnoty. Opakujte pouzivanie napriec vsetkymi vasimi dokumentmi. Setrí cas.

Na platených planoch sa nastavenia synchronizuju napriec vsetkymi produktmi anonym.legal. Nastavte ho vo webovej aplikacii. Objavuje sa v desktopovej aplikacii a doplnku Office do piatich minut. Sifrovacie kluce pouzivaju zero-knowledge obalenie. Iba vase heslo ich môze desifrovat.

Viac o tom, ako doplnok Office zvlada rovnaky pracovny tok vo Worde, najdete v Redakcia doplnkom Word pre pravnicke firmy.

LibreOffice vs. Microsoft Office

Obidve rozsirenia zdielaju rovnaky backend. Rovnaky text dáva rovnake vysledky vo Writeri aj Worde. Motor je jeden a ten isty.

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

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.
