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.
