FIELD: computer technologies.
SUBSTANCE: method and system for deleting textual personal data from a document image. In the method, a primary image of a document containing personal data is obtained, pre-processing of the said image is performed, in which an image of a given size and resolution is formed, the pre-processed image is reduced by four-fold transformation using the Gaussian pyramid transformation, text personal data is deleted by applying at least at least one morphological operation with a window of 3×3 pixels to the reduced image of the document, the resulting image is enlarged by a four-fold transformation using the Gaussian pyramid transformation, the final image of the document is formed with deleted textual personal data.
EFFECT: enabling depersonalization of data in the image.
