Security for shared graph

Security for shared graph

Hi,

I am planning to use graphs in a intranet environment. My challenge is security.

I have the same graph, that I want to show to different users. But the users have different departements, and must not have access to data outside their departement (depId=x). But since there at 10 departements I would like to maintain the graphs only once in Zoho Reports.

So, I can use filters to achieve this, by passing parameters to the iframe. However, that is easily bypassed since a user can change that in the HTML. Can I do this in a secure way, withouth creating a new version of the graph for each user?
