Irdeto Access, a world leader in content protection and management
and a subsidiary of Naspers, a multinational media group, has patented
a new technology that allows content owners to trace the source
of pirated content. The technology is part of Irdeto Access' overall
security management programme offered to pay-media operators and
With the existing illegal possibilities to distribute stolen content
over the Internet, it is crucial that content owners have the tools
to be able to trace the source of content leakage. The technology
developed by Irdeto Access enables an operator to trace the initial
smart card or device that was originally used to decrypt the content.
This provides content owners and network operators with a powerful
tool in monitoring the piracy of content.
An official release informs that the technology developed by Irdeto
Access allows unique fingerprints to be inserted into encrypted
content under the management of a secure device or smart card. The
advantages over conventional fingerprinting techniques include the
ability of the smart card to control the insertion of the fingerprint.
This means that the fingerprint insertion process is secured within
the smart card and cannot easily be tampered with. In addition,
it provides an upgrade of watermarking or fingerprinting the algorithm
without impacting the set-top box or player device. This means that
as new watermarking techniques are developed these can be deployed
without requiring expensive upgrades in the field. Moreover, an
end-to-end encryption of the content is now possible. There is no
need to decrypt content to insert the watermark at any point in
the delivery chain.
As part of its successful security programme, Irdeto Access will
continue to apply its three-pronged approach to piracy using advanced
encryption technology, extensive investigation of suspected fraud
and counterfeit operations, and close cooperation with international
Furthermore, a new smart card version will be developed and employed
routinely. The smart card will be released irrespective of whether
the existing card has been hacked or not, reducing attractiveness
of piracy due to the smaller volumes of each card version in the
field, as well as reducing the costs inflicted on operators by piracy.
