timestamps for licensed security as service

[garyg]

Not sure if this is the right forum, but thought this is one way it might work ... I didn't see anything like general ...

I'm looking at inserting a blowfish algo'd timestamp into a file to be used as a first time run check so that I can do a sort of 30 day time trial period for my J2EE app. Rather than scatter this check throughout different places in my MVC's components, has anyone done this already?

I was thinking maybe it might be run as a service since these are some of the first things to get loaded ... which would just stop the entire server from being brought up ... or any advice about how might be a better way?

Any advice much appreciated.

You have to link the check to the code it
protects. Otherwise people will find ways
to circumvent it.
e.g. don't deploy the service doing the
checking

At least in the UK, this kind of processing
is technically illegal. The data protection act
guarantees a user can see their data using
normal operations. Stopping them creating
new data is ok.
