Data Security

I want to keep my business data save on my computer. My computer is in the store where i goes only after 3-4 weeks. I have plenty of world, excel, pdf files saved on my computer containing my business data. I want my staff to access these files. But i don't want them to copy or transfer this data. I want only them to email that data only to me when required. They should not be allowed to attached these files to their personal emails.
Can somebody help me???

 

Do you want your staff to update these Word and Excel files ?

 

No, all, but only some of these.....

 

There is no way to do what you want. Computers gives rights by 2 categories: READ and READ + WRITE. So when you grant permission to READ, the user can see the contents of the file. He can also copy and email the file. When the user has READ + WRITE, he can modify the file plus all the things he could do with a READ.

Perhaps you can put the files into a Windows account and only let a trusted employees have access to the files by giving him/her the account password.
