Hi - I am looking for a solution to a clients requirement. They want
to distribute a database of info on CD, which user can search on
selected fields and results will be displayed.
The data and database MUST be encrypted and be displayed on-screen in
a format that cannot be 'Copy/Pasted'. Apart from the search results
displayed on-screen, user must NOT be able to extract multiple records
to use for Spamming.
Database about 1/2 million records with 10 fields.
Ideally application must run from CD with no setup.exe to install on
their PC.
Doesn't have to be VB, doesn't have to be a database, but must run on
Windows 95 upwards. We intend sending out hundreds of thousands of
CD's so s/w licensing cost is major issue
What can you suggest?
Most encryptions can be broken, and will be if it's worthwhile to do so,
("hundreds of thousands" might be a clue that it would be). Many big
organizations include encryption as a simple way to discourage the casual
snoop, but don't pretend that this makes the data secure. An example is
Yahoo Messenger log files. Of course, a picture of the screen is always
available, TTBOMK, with Print Screen, and there are resident programs
available that enhance this capability. Just for my own interest, why
would users want to view data (e-mail addresses presumably) and not use
them?
If I needed to do something like this, I think I would be more likely to
store that data on a server somewhere where it was extremely difficult
(nothing is impossible) for anyone to access, and make the screen shots
available through some kind of internet application, with paid licensing
required, and one of those, copy the characters you see in this picture
procedures to prevent programmed mining. Even then, a patient user could
get details by copying the html source of the page, although some clever
script might make this difficult.
