Abstract: A method for inserting information into a first image including N1 rows×M1 columns of elements includes: a) obtaining, from the first image, a second image including N0 rows×M0 columns, N0 ≤N1 and M0≤M1, b) generating initial information including N0 rows×M0 columns, c) obtaining intermediate information including N4 rows×M4 columns of elements, so N4≥N1 and M4≥M1, and N4=kx.N0 and M4=ky.M0, 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.
