Hi, I have an iphone application and I need to send some data from user app clients to a server. so I build a Java server on tomcat with restful webservice API. The data about the users is just user appleid, object id and duration time that the user viewed the object. I want to send it any time users open the app. my question is: what is the level of the connection between client and server need to be secured? I don't want a complicate solution and I also don't want apple to reject my application. what apple expect me to do in those kind of apps? Thank you guys.
