    Product activation is popular by software vendors to shield their applications and enforce license agreements. Even though some users mind any type of license management, modern product activation systems pc other techniques from both the vendor’s and also the end-user’s perspectives.

    Software vendors use license management for numerous reasons. They can be worried about defense against piracy, and protection against users exceeding their agreed license terms (such as the amount of installations that run inside a customer company). License management also permits the software vendor to formulate, distribute, and support one sort of their application, but offer different license terms at different prices to be able to markets.

    As an example, the vendor are able to use the licensing mechanism to provide trial licenses, perpetual licenses, subscription licenses, set limits around the product features or modules enabled, set usage limits, combination’s from all of the above, and provide straightforward upgrades in capabilities, by having one executable (some license management systems even let the vendor to also offer floating licensing either over the end-customer’s network or perhaps the Online on this same executable). Finally, license management can encourage the vendor to automate fulfillment, management and reporting, so reducing operations costs and offering immediate delivery worldwide 24×7 on their customers.

    A vital concern for software vendors is ensuring users don’t merely supply the software to unlicensed friends and colleagues, and even post it on the internet for everyone to download. The standard option would be called node-locking, where each user’s installation is locked to 1 or more parameters of the system, such as the MAC address. Each and every time the application form runs, it reads, say, the MAC address from the computer where it really is running, and will proceed provided that the address it reads matches usually the one recorded for that license.

    Older systems for license enforcement include dongle-based licensing and key-file-based licensing. A dongle is really a hardware device that connects to the user’s computer; in the event the application runs it checks for that existence of the dongle and definately will run only when it finds it. Dongles do therefore let the user to move their license around, only by physically relocating the dongle. With key-file-based licensing, the license limits and node-locking parameters are encrypted in a file, which is shipped to an individual and study from the application each and every time it runs.

    These approaches have some of disadvantages. Dongles need the distribution of the hardware, effortlessly that entails in material cost, shipping cost, delivery times and management with the vendor. They may be widely disliked by end-users, that don’t desire to wait for these phones arrive, keep track of them, ask them to get noticed of the computer and so on.

    Key-based licensing improves on dongles because the encrypted key files could be delivered immediately by email, and impose no hardware burden. However, they are doing require user to supply the names of the locking parameters (or chance a utility to learn them), and never allow users to readily move their license from machine to machine, therefore relocating would require a new key file. Upgrading to some user’s license, like extending a regular membership, also necessitates the generation and delivery of the key file.
