Set specific filter for one user (in the administration)

Hi all,

I'm working on a mashapp which displays performance of different users and my problem is to create users for each one but with a specificity, when one user get into the mashapp he just sees his performance and not the others (for confidentiality).

For exemple, when "kevin smith" enter his user and password and get into the Mashapp, the filter on his name has to be fixed .

Is it possible ?

Thanks for your help,
