SpinWare PortaNet

SpinWare PortaNet encrypted media files can be placed on the DVD-ROM portion of a DVD-Video disc. These encrypted files can be seamlessly unlocked in real time through the end users Internet Browser, by way of an authorization from a remote web server. PortaNet also contains an e-commerce engine that provides secure access to content on the DVD disc in exchange for revenue. PortaNet's decryption engine is data agnostic, it can be used to lock and unlock any type of data, including MPEG1 and MPEG2 movies, executable files, or even entire Video_TS directories.

While there are several ways to use PortaNet to enhance a DVD-Video title, some of the most popular methods include:

	Providing ancillary content to the end-user in return for something of value. This can be as simple as letting the user see some behind the scenes footage after they complete a user registration form on your web site. Hidden content on the disc can also be unlocked when the end user pays an additional fee, thus providing an after market revenue stream from an Enhanced DVD title.
	Building brand awareness and customer loyalty through a program of timed released content stored on an Enhanced DVD disc. Additional content can be stored on the disc and unlocked over a period of time, thus encouraging the end user to visit a web site many times over a period of time.
	Implementing a Pay-per-View business model. Entire DVD-Video titles can be encrypted and stored on an Enhanced DVD title. Decryption and playback of this locked content can be done easily over the Internet after the end user has paid a "rental fee". Once the playback session has been completed the locked content on the disc will revert back to its locked condition.
