Patent for Sale:Conditional Access System for Content Distributors & Service Providers
As expanding the boundaries and enhancing the reach of their services to consumers, content distributors and service providers also expose premium content to piracy with the risk of being mishandled.
In the same way people make illegal copies of copyright works, they make unauthorized smart cards and other decoding equipment with the intention of selling them, depriving the broadcaster or cable operator of the payments that would normally be paid for reception of the transmissions. The pirates are dynamic and always looking for gaps in security. There is a need for solutions to secure Conditional Access systems (CAS) against increasingly sophisticated intruders. The four patent families in this portfolio are focused on enhancing the security for CAS.
Areas covered include:
- Techniques to effectively protect a system against unauthorized users. For example Pay TV customers who share their key with unauthorized users.
- Public and secret key encryption
- Key management and intruder ID
Primary Application of the Technology
- Better security for subscribers and service providers.
- Reduces piracy.
