Abstract: 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.

Abstract: 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.

Abstract: A device, system and method are provided for processing structured documents for display. Content of a first viewable portion of the structured document having a fixed position in relation to a viewport is rendered as first rendered image data. Content of a second viewable portion that does not have a fixed position is rendered as second rendered image data. The first and second rendered image data are composited, and a resultant composited image is output for display. In response to a scroll or zoom command applied to the document, and in particular to the second viewable portion, the second rendered image data is updated and composited with the first rendered image data. Compositing can be carried out by a graphics processor separate from a main processor in the electronic device. When no fixed position elements are present in the structured document, the main processor renders the entire content without compositing.
