Abstract
Improved watermarking techniques for text content are disclosed. An example methodology implementing the techniques includes selecting a sequence of text characters to form a watermark and representing at least one text character of the sequence of text characters by a code which, when inserted into text content, does not affect the appearance of the text content. The methodology also includes embedding the code which represents the at least one text character of the watermark into text content so that the code enables identification of the at least one text character upon extraction of the code from the text content.
