Re: CAPTCHAs – Understanding CAPTCHA-Solving Services in an Economic Context

Missy Harvey has prepared a useful guide for summarizing paper contributions
on p. 9 of this document: http://www.cs.cmu.edu/˜missy/WritingaLiteratureReview.
doc. Using the adapted template avaialable for download from http://lyle.smu.edu/˜tylerm/
courses/econsec/reading/review-template.txt, please read and summarize the following paper
on CAPTCHA economics (http://cseweb.ucsd.edu/˜mmotoyam/usec10-recaptchas.pdf).
As a guide you may be interested in reviewing the summary I wrote for a related paper: http://lyle.smu.
edu/˜tylerm/courses/econsec/reading/review-pow-clayton.txt.
Please first write responses to each of the nine points raised in the template. After you have done that, craft
a standalone summary using parts of your responses to the questions in the template. Be sure also to include a
reference to the original paper in ACM format (see bottom of this page for examples: http://www.acm.org/
publications/latex_style/). The standalone summary should be in the range of 200–400 words long.
