Anonymization of a French invoice

Document anonymization is crucial for data protection, but traditional methods like covering, redacting, or using correction fluid are ineffective. Hidden information can be easily recovered with simple image processing techniques, posing a risk of data leakage.

The ethics of data anonymization revolves around balancing privacy protection with the need for data utility in AI and research. While anonymization safeguards individuals’ identities, it raises concerns about de-anonymization risks, consent, transparency, and the fair use of data in AI systems.
