Security and the ODBC

Ok, quick one. I have a Informix 7.x server running with a database. The users connect to it via Informix-CLI client from within Win95 using a complied program. The complied program handles the "business rules" of the database as far as insuring they have security etc. Simple example: One table they are allowed to insert rows and delete etc. But, the application checks a column called rsrc_id and doesn't allow them to delete or change a row if it isn't theirs (the rsrc_id is users name). It works fine. Remember this is just an example and I'm not wanting to know about Triggers, SPL etc. The issue is this: The CLI client is an ODBC driver. The user can use any ODBC application and point it to my Informix Server. Example being MS-Access. Now MS-Access (along with others) can just do what ever it wants to my data. In the above example the user is allowed to delete from the table and the application is ensuring the rsrc_id matches. So, is there a way to tell Informix to accept connections based on an application? Any ideas other then writing a billion triggers, SPL etc etc?
