Abstract

The invention provides, amongst other aspects, a method for embedding a bit sequence, comprising: providing the bit sequence and a text string comprising words; identifying, among the words comprised in the text string, carrier strings suitable for embedding; generating formatting data associated with said text string, said formatting data comprising instructions for embedding, within the respective identified carrier strings, respective bits of the bit sequence; wherein the identifying of carrier strings comprises identifying, for each carrier string, one or more carrier words such that the carrier string comprises at least two spaces, the spaces being letter spaces or word spaces; wherein the embedding of a respective bit relates to altering each of the letter spaces and/or each of the word spaces of the respective carrier string so that the sum of altered spaces if the value of the bit is zero is distinguishable from the sum of altered spaces if the value of the bit is one.
