1. A method of anonymization of images against source attribution comprising: irreversibly transforming an original digital image into an anonymized image by: determining a plurality of seams for the image; adding or removing at least one pixel from one of the determined seams; wherein pixel correspondences between the original image's sub-blocks and the anonymized image's sub-blocks are not preserved, removing one or more fake seam by: a) identifying an image region that lies between two determined seams of the plurality of seams; b) selecting a pixel in the identified image region; c) calculating gradient energy in a first direction and a second direction from the pixel in the identified region until a minimum energy is found as a full horizontal or vertical fake seam; and d) removing the full horizontal or vertical fake seam.
