When multiple users use same login id to oracle database and perform tasks. How to find out which users, through which system, session logged in and what are the steps that they have performed. Is there any automated tools through can we scan this?
There is any digital signature which we can apply on the tables created by multiple users using same loginid, without the knowledge of these users, while they create the tables and later by checking this digital signature to identify the user who created the table ?

we can use osuser and machine columns from V$session table and a combination of triggers on tables to record that info. But then say if its a web application through which users operate then you may have to resort to maintaining a user list in your DB and recording that.

they only have less privileges, the problem arises when the tablespace grow and the users drop their tables, and then the they also have to clean up the recyclebin, but should ensure that only the tables dropped by them are purged.

To be able to create segments is not a small privilege.
The proof: they can use space and create troubles.
Moreover, if a user can purge others objects in recyclebin they are very privileged.
