Diffee VS anonimiza.do

anonimiza.do's answer:

It is built around Spanish documents rather than adapted to them. It validates DNI, NIE, CIF, Social Security numbers and IBAN by check digit, deliberately leaves references to laws and decrees untouched, groups every mention of the same person so one decision applies throughout, and finds personal data that is easy to miss: inside QR codes and barcodes, in Word footers and tracked comments, and in indirect references such as "the mayor of a town of 3,000". It is also certified under Spain's National Security Framework (ENS).

anonimiza.do's answer:

Because black boxes drawn in a PDF viewer do not anonymize anything: the text stays underneath and comes back with copy and paste. anonimiza.do actually replaces the data, removes metadata and returns the file in its original format, with review before publishing and an activity log. It recognises Spanish identifiers out of the box, runs on EU servers with no international transfers, and starts free: 3 documents a month with no credit card, then €29/month (€23 billed annually) for 50 documents with OCR, batches and API.

anonimiza.do's answer:

Organisations in Spain that have to share or publish documents containing personal data: law firms and in-house legal teams, HR departments, public administrations publishing on transparency portals and contractor profiles, clinics and hospitals preparing records for research, accounting and advisory firms, and insurers. It suits both the professional who anonymizes a few documents a month and the organisation that needs batches, an API and single sign-on.

anonimiza.do's answer:

anonimiza.do is built by Cedesa Digital S.L., a software company in Badajoz, Spain, certified under Spain's National Security Framework (ENS). Its CEO, Suso Merino, is a computer engineer with a university degree in technology law who works as a court-appointed computer forensics expert in Spain. The product follows the same standard: anonymization has to hold up under scrutiny, not just look right on screen, so it replaces the data instead of covering it, strips metadata, keeps an activity log and validates Spanish identifiers by check digit.

anonimiza.do's answer:

Detection combines several layers, because no single method works for everything: pattern rules with check-digit validation for structured identifiers such as DNI, NIE, Social Security numbers and IBAN (ISO 13616), NLP models for names and context, coreference resolution to group mentions of the same person, and OCR for scans and photos, where the substitution is applied to the pixels themselves. It runs as a web application with a REST API on AWS in Frankfurt (EU), with TLS 1.3 in transit and AES-256 at rest.
