Nowadays, the storage and transmission of some types of documents requires the removal of personal information from involved users. Automatic text anonymization or de-identification is a solution for hiding all sensible information contained in the documents. Although the problem has been mainly studied for plain printed-text documents, there are not works where the de-identification task also produces anonymized document images with the same text fonts as those in the original documents. This data augmentation process could be applied to train a system for document image classification. In this paper, we describe an implementation of an automated anonymization modular system for printed-text image documents written in Spanish. System evaluation performed on a dataset of invoice images shows the viability of our proposal.
