Adding entries in Dynamic View - no contact list



I need respondents from the same company to access a dynamic view, add a new entry and be able to access it later on. Each respondent should not see what the other respondents entered, knowing that I do not have the list of respondents. Will it be possible to realize what I just described in dynamic view? if not, how can I modify the source sheet to make this task possible, knowing that I will have more than 50 respondents that will need to access the view and add their entries?
