License management / copy protection

[EwaldP]

Hi,

has anybody experience with license management tools / copy protection? Do you use a self-built tool or 3rd party tools?

My requests would be:
- licensing our product to each customer (Priority A) - including licensing additional software parts
- check concurrent user (Priority B)
- copy protection (Priority C)
- multiuser up to 100 user

Many thanks
Ewald

Hi Ewald,

we don't use any third party tools. Our solution is very simple but is working for us so far. We import the license Informations into the Database, with checksums to assure license integrity ecc..
On program start we check the license table for programm unique ID, version number, expire date ecc. If not the App does not start.

For the concurrent users on the other hand we use a second table on the DB where all sessions are logged.. Every programm check this session table for other concurent users. This Table is updated every few seconds.

This may not be the best concept but it is working fine for us because we have multiuser apps working on a central database,
