how can i restrict an user from entering the data directly into the address bar by keying in the numbers and going to the specific resource even if he is not allowed to is there anyway of encrypting it so that he cannot get the numbers itself
The important part is not so much the filter (which can be used to implement this, but there are other ways as well), but that any access to data is checked against the credentials. Any database query should contain a clause that filters out any data the user is not allowed to see.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
