Hi folks -
I work for an non-profit organization that provides retirement/medical benefits. There are a number of PDF fillable forms that we would like to provide access to via our portal, forms that may require our users to enter sensitive information such as Social Security Number, etc. This isn't really a pressing concern for our users on their home computers, but we are concerned about caching of this kind of data on a borrowed machine or a public machine.
I know that Reader local caching can be avoided via deselection of the "Use Page Cache" setting. However, we'd like to take this concern out of the equation from the start and avoid having the users themselves being required to stop the local caching. Is there any way to create a PDF that will not be eligible for local caching? Does anyone have any suggestions other than that for how we can avoid this situation?
Thanks in advance!
The pdf file must be downloaded to be able to be viewed. End of Story. When it is stored in a temp directory it is called cached, but it is downloaded. If it isn't on the computer then it cannot be viewed.
Thanks for the reply, Michael.
I understand what you are saying, and was aware of those aspects of PDF usage, but let me re-phrase what I am asking: if a user looks at a fillable form, fills out their info, prints the completed PDF form, and closes either Adobe Reader or their browser session that presented the PDF (more likely the latter scenario), how can we ensure that none of the information they entered remains accessible on the computer that person was using?
