dont understand what is meant by unathorised hands - any reputable ISP will provide password protected access to your web pages so they should be secure.
In practice once you have published on the web you cannot prevent others from using the info - several have taken my pages and published them under their own name - even if you put up as pdf files they can still be accessed by most OCR programs and converted back into text - even putting info up as .gif or .jpg image files only makes it more difficult but not impossible
