Are there any grammar, punctuation, or spelling errors? My Comments: - Abstract: "and save it in a required file format." it should be "saved it in a...." - Introduction, first paragraph: "one of the fastest flourishing Internet markets", use small-case for word "internet" - Use one tense to express past work, either past or present. For example. "The work in [7] presents" or "The work in [7] presented". - Please revise tabbing of paragraphs in all the paper.

Detailed comments? - Figure 8 should be enlarged to make it readable. - Rest of the paper is written very well. - Paper can be accepted with minor corrections.
