A method, system, and computer program product for access control for a server application provided between a server executing an application and a client. Access control is added to an existing server application (for example, a legacy application) without changing the application or the database. The method includes: capturing a screen from the server application; determining if the screen includes sensitive content; and checking a client user's authorization before sending a screen including sensitive content to the client. Determining if the screen includes sensitive content may include: carrying out text recognition on the screen content; and analyzing the output of the text recognition to identify sensitive content.
