A system and method for protecting text from unauthorized access. An original data set including a plurality of character code values is received, where each character code value corresponds to a respective character defined in a character definition standard. A new value corresponding to an undefined value within the character definition standard is determined for each character code value. An augmented code point-to-glyph mapping is created based on the new values with mappings between each new value and a glyph to render a character associated with the character code value. A new data set is created based on the data set and the augmented code point-to-glyph mapping by replacing character code values in the data with new values corresponding to the text character codes. The new data set and the augmented code point-to-glyph mapping are sent to a destination.

Data security using alternative encoding

A system and method for graphically encoding text. A textual data set comprising a plurality of encoded text characters that corresponding to at least one text character to be visually rendered is received. Based on the textual data set, a drawing instruction set is determined that has a respective drawing instruction to draw at least part of a glyph of each of the encoded text characters. Each at least one drawing instruction excludes an indication of a correspondence with an associated text character code, and each respective at least one drawing instruction for a specified text character excludes instructions to repeat other drawing instructions for other instances of the specified text character.
