Identifying uniuq application

[pgattu]

Is there any way in windows to identify an application(exe) uniquely in windows(Aprt from the exe name or fully qualified exe path).

My scenario here is like this:

I have server which stores data for different clients.data of the client1 can not be read by client2.

How to differentiate the two clients(apart from names).

Please help me to find a solution.

Are you the programmer of the clients? Your client could generate a session cookie of sorts and use this as a token with each transaction with the server.

Thanks for reply!!

I am not writing the code for clients. And here in my scenario client can not provide any authenticated or session info to server.

Server itself has to read some attributes of the client (exe) and able to identify with some unique identifier.

When you use "client" and "server" what is the relationship between the two (those tend to be pretty generic terms)? How do they communicate? Are they on the same machine? All of these are important considerations when trying to figure out your problem.

In my scenario :

Client uses the server to store and retrive data. Server stores it by signing.

My problem here is Server needs to differentiate between clients(owners) when they request the data back to read.

Client and server runs on the same PC.

I am also planning to replace the server with storage component (dll).
