How safe is sealed content?
• A. Content is sealed using a combination of industry standard encryption and digital signatures to protect it from unauthorised access and tampering. Once sealed content has been decrypted and rendered by the Unsealer, it is protected against unauthorised use by the following mechanisms: • Unsealed HTML and PDF content is never cached in the local file system, so unsealed content is never accessible to other applications • The Unsealer prevents unauthorized screen grabbing of sealed content • A trusted clock runs independently of the system clock and prevents users from subverting time based licensing rules • Your rights cache cannot be copied to another computer and used to open documents. Your rights cache is locked to your particular machine. • Rights management is handled within the core of the SealedMedia software so that rights are never exposed in communications between the server and the Unsealer.
