Software based Software License Protection is the earliest protection method available and usually the protected application will require user to key in Serial No., License Key or Unlock Code to activate the software license. Most of the third party Software License Protection provider will provide a ready made encryption engine of which software developers can use this to encrypt their software applications as to add the protection layer onto their software applications. Usually, the protection will tie with some unique ID from the computer system such as Hard Disk ID or Network Card ID. Also due to this reason, usually if there is any hardware problem such as Hard Disk or Network Card spoiled, license re-activation will be needed. It will also means the Software Developers will need to keep track and verify the License Key reissue request from the end users, of which some end users might try to take advantage on it. As Software based Protection do not come with any additional devices, it will have to store all the licensing information into the computer system and mostly hide it inside registry.

Pro
- Lower ownership cost
Most probably it is cheaper than Hardware based in long run if you purchase from third party provider with one-off purchase (without license loyalty model).
- Easier to implement
Usually it comes with limited security features and thus the implementation can be easier.

Con
- Lower security
As Software based can only store and hide all the protection information into the computer system, it will come with higher risk as hackers are able to find those information easily and perhaps crack it.
- Too dependent on computer hardware
Most Software based protections are too computer hardware dependent and thus if any computer hardware problem, reinstallation or license reactivation will be required. There are also possibilities some end users will try to take advantage of it by requesting additional license keys for additional workstations instead.

The politically correct version is that to clarify a potential confusion caused by the ambiguity of the word “free”, so that the perception of free software is not anti-commercial, the label open source (contributed by Chris Peterson) stuck. The official version is that it was to shed the confrontational attitude that had been associated with free software in the past and sell the idea on pragmatic, business case grounds to the commercial world. Whatever it may be, Netscape listened and released their code as open source under the name of Mozilla. That was the beginning of the contemporary open source movement, whose main champion today allegedly is the Open Source Initiative (“OSI”) which makes and continues to make a case for the open source software to the commercial world. Consequently, we have seen the application of the open source philosophy in other fields including biotechnology. Linus Torvalds, a finnish software engineer who initiated the development of the Linux kernel went as far as saying “the future is open source everything”.

According to the OSI, the case for open source software is simple – free access to read, redistribute and modify the source code of a piece of software results in a rapid evolutionary process that produces better software. Advocates of open source argue that when programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.

Effects of Software Piracy

When software is pirated, consumers, software developers, and resellers are harmed. Software piracy increases the risk consumer’s computers will be corrupted by defective software and infected with viruses. Those who provide defective and illegal software do not tend to provide sales and technical support. Pirated software usually has inadequate documentation, which prevents consumers from enjoying the full benefits of the software package. In addition, consumers are unable to take advantage of technical support and product upgrades, which are typically available to legitimate registered users of the software. Pirated software can cost consumers lost time and more money.

Developers lose revenue from pirated software, from current products as well as from future programs. When software is sold most developers invest a portion of the revenue into future development and better software packages. When software is pirated, software developers lose revenue from the sale of their products, which hinders development of new software and stifles the growth of the software company.

Kinds of Piracy

End User Piracy -

Using multiple copies of a single software package on several different systems or distributing registered or licensed copies of software to others. Another common form of end user piracy is when a cracked version of the software is used. Hacking into the software and disabling the copy protection, or illegally generating key codes that unlocks the trial version making the software a registered version creates a cracked version.

Reseller Piracy -

Reseller piracy occurs when an unscrupulous reseller distributes multiple copies of a single software package to different customers; this includes preloading systems with software without providing original manuals & diskettes. Reseller piracy also occurs when resellers knowingly sell counterfeit versions of software to unsuspecting customers.
