>I´M BUILDING A DATA SENSITVE APPLICATION USING VFP 3.0, BUT I REALIZED THAT MY DBC´S AND DBF CAN BE ACCESSED OR EXPORTED USING OTHERS APPLICATIONS LIKE ACCESS AND VB. HOW CAN I USE A SECURITY SYSTEM THAT PROMPT FOR USER ID AND PASSWORD LIKE SQL SERVER OR SYBASE TO PREVENT OTHER APPLICATIONS READ MY DATA.

basically the only way to do it is to enctypt the data

there is a 3rd party tool called cryptor from Xitech that supposed to do encryption/decryption on the fly - I haven't used it though
