Abstract: A method and system for processing data is described, the method and system including encoding a string of symbols, each having a respective symbol value, as a sequence of vectors, each vector including a respective number of repetitions of a sub-vector of a predefined length, such that the respective number of the repetitions in each vector in the sequence is indicative of the respective symbol value of a corresponding symbol in the string, and applying a watermark to an item of content including digital data by inserting the sequence of the vectors into the data. Related methods, systems and apparatus are also described.
