Abstract:
Methods, apparatus, and articles of manufacture to encode auxiliary data into text data and methods, apparatus, and articles of manufacture to obtain encoded data from text data are disclosed. An example method to embed auxiliary data into text data includes selecting a portion of auxiliary data to be encoded into text data, mapping the portion of auxiliary data to a first set of one or more encoded characters representative of the portion of the auxiliary data, mapping a position of the portion of auxiliary data within the auxiliary data to a second set of one or more encoded characters representative of the portion of the auxiliary data, and generating encoded data by including the first set of encoded characters and the second set of encoded characters in the text data.
