Abstract
A method for inserting information into a first image including Nrows×Mcolumns of elements includes: a) obtaining, from the first image, a second image including Nrows×Mcolumns, N≤Nand M≤M, b) generating initial information including Nrows×Mcolumns, c) obtaining intermediate information including Nrows×Mcolumns of elements, so N≥Nand M≥M, and N=kx·Nand M=ky·M, kx and ky being integers ≥1, the elements organized into blocks, d) obtaining information to be inserted from the intermediate information, including: generating symbols representing noise, including as many symbols as block elements, at least one < >0, so the result of a function applied to the symbols=a chosen value, adding each symbol to the corresponding block element, and e) inserting the obtained information into the first image.
