That’s not gonna be easy to accomplish!
There are always ways to get this done, I.E:
1. Screen capturing (And saving to an external storage medium, Or just e-mail it)
2. Just copying it as-is to an external storage medium (Or e-mailing)
3. Printing.
4. Writing it down on paper (Either immediately, Or later on, Some people have excellent memory recall!)
5. The use of cameras (Don’t forget that every mobile phone has one these days!)
There might be software means to prevent the first 3, But certainly not the rest!
Why do you share “sensitive” information with your employees if you don’t trust em?
And if that is the case, Why did you hire em in the first place? It just doesn’t make sense to me.
Answer #3
thanks for your replys
first of all the data i use are database like informations and i use them for work, without these data i am collecting employees can’t work, then as you know database are very valuable because they are mine i worked hard to collect, so share them with others doesn’t make sense.
You are right there will be always ways to get them, but i would like to make it harder
Answer #4
As already been pointed out by , You could use DLP (Data Loss Prevention) software to get this done (Just Google it). But again I say, No point working with people you don’t trust!
Answer #5
