The order of ideas are organized logically. Clear headings and subheadings guide readers through the paper easily. The paper also provides good transitions among paragraphs and ideas.
As a person who interests in biometric authentication technology, I totally like to read the whole paper to gain hi-tech information. However, the paper covers too much on technical terms and definitions. The paper should provide a little bit analysis on the presented information. It may be good enough to satisfy readers who are not in engineering field. Nonetheless, engineering readers may expect more useful information rather than descriptions and definitions about the technology.
