Generating survey codes for Amazon Mturk responses


I came across this article (https://www.sawtoothsoftware.com/support/knowledge-base/general-issues/1477-how-to-use-mechanical-turk-for-your-surveys) on how to use Amazon Mturk for conjoint surveys. However, the links detailing how to create a survey code is not working. Could anyone guide me as to where I can find information on creating survey codes using either random number generation or through cryptography approach? Thank you.

Best regards,

Vishnu, we just updated the help file links in this particular article (http://www.sawtoothsoftware.com/1477) to direct to the help files for Lighthouse Studio rather than the help files for the older SSI Web product. It should work for you now.

Hello Nathan,

Thanks very much! I am a little confused on how to generate random numbers, at the end of the survey. I am trying to work out the cryptography approach. First, I need to create an open end question asking for the respondents mturk id, and then generate a sequence for that, and put it in the terminate page?

Is this right?
Hi Vishnu,

The idea of the cryptography approach is just to take one input and mess around with it so that it looks like randomness to the respondent, but is recognizable to you.  The suggested text in the article is simply one way of doing this where we use a combination of the respondent number and the Mturk ID to create what appears to be randomness to the respondent.  

You could take a much simpler approach, for example, and just report back to someone their Mturk number with the respondent number before or after it.  If you are unfamiliar with writing scripts in the software, you might find the following documentation helpful: https://www.sawtoothsoftware.com/help/lighthouse-studio/manual/index.html?hid_web_ssiscript.html
Dear Brian,

Thanks very much for your comment and the documentation link. I managed to use the cryptography approach to gather respondent numbers. The Lighthouse documentation was very helpful.
