Authorization in Restful apis

I am working on restul api and unable to find a solution to my prob.

I have a get request to get resource by ID, I have implemented basic authentication.

Now if somebody changes the Id in the get request , He can access resource of other users as well.

How can I restrict user to see his resources only, Do I have to create some security filter for every type of resource?

Any Link to best practises to prevent this kind of issue will be appreciated!
