I will provide copy protection for excel files

I provide copy protection for excel files protecting formulas and VBA codes completely from being accessed or copied. Copy protected excel file is only for viewership with editing. Only authorized users or paid customers can use it. Licensing system is used with following features:

• Allow/Block Saving
• Allow/Block Printing
• Allow/Block Copying
• Allow/Block Cutting
• Allow/Block Pasting
• No Drag & Drop
• No Shortcut Keys

I make files remarkably secured against their illegal copies using "Digital Rights Management (DRM)". Machine locking technique is used so copy protected files can be run only on registered computers. "Keys Generation System" is highly customizable to set following properties configuring trial or full version:

• Expiration
• Days
• Hardware Locking
• USB-Based Locking

Copy protected files can be sold to customers using CD/DVD disc, USB drive or internet. 

Copy protection can be checked and tested freely before considering any order. So, feel free to contact me here. This gig contains price for single file.
