CardSharing
Cardsharing which is otherwise termed as Control Word sharing is the
process by which a lot of customers or receivers of digital television
are let to make use of a pledged contribution network of television
whilst having just one subscription card. The operation of the
protection of limited usage smart card technology is always done and
taken care by DVB standards security. Deciphering an Entitlement Control
Message is generally done by smart cards that help in seeing the
scrambled or disorganized material by providing the control word. When
the sharing of card is done, there is bypassing of its security features
which is then stopped by software that helps in sharing the deciphered
control word throughout the network.
Since the size of the Cardsharing was way too small, as in only 64bits,
it was easier to get them delivered to plenty of clients through their
Ethernet connection in their home PC. This led to multiple users sharing
their control words to their group members and in turn receiving
various other satellite TVs through the control words of others. There
are various other satellite servers that have been created in such a way
that one of it has access to so many other cards. Thus results in
Cardsharing. It is a massive and complicated process in which one
individual who owns a control word has the control over sharing that
word between their network people, either local ones or international
ones. This individual will be given the rights to decipher his networks
signal using his card or control word and will be given the authority to
use his subscribed network. A few of the providers who are content
oriented have the tendency to let their receivers use it only if they
purchase a second smart card with an additional cost.
DVB-CSA is the standard system used for scrambling the important content
using its respective Cardsharing process. But to restrict this process a
few other parties have implemented various other strategies.
Considering its lethality, pirate Cardsharing can be easily identified
by simply tracking the IP address from which the person browsed in his
internet. Since the frequency of the control word or Cardsharing
is too small, few providers handle it technically by increasing or
changing its size, considering this as an easier method. Very frequent
changes have been found in this service that only frustrated their
viewers who are highly stressed.
