The Patents have specific utility to DRM, an increasingly important field.  Many companies are developing DRM systems that disable software and digital content that has not been properly licensed. The Patents have broad coverage for DRM applications, and specifically claim technology that enables the remote activation and disablement of digital content, such as audio, video, text, data and image files. The Patents cover metering and provisioning access to digital content distributed to PCs, PDAs, smart phones, game consoles and other devices. SVS client agents could be embedded in digital content, such as music, video, text and data files, to encrypt or decrypt content based on rules established by content publishers such as time-based trial periods, single use/pay-per-view and pay-per-use, subscription-based services or file copying and sharing.   The vulnerability of password-protected systems to hacking is a well documented problem made worse by careless password protection practices of frustrated end users who struggle with the ever-increasing number of passwords they're expected to manage. Because the SVS architecture functions as a transparent background operation that does not require end user passwords, it addresses a major source of user frustration while at the same time strengthening protection of digital assets for content publishers.
