Definitions
- the present invention relates to a system for controlling access to digital data online or offline by means of a software key server.
- It relates generally to the field of transmission in digital form of information of all types, and in particular of digital television broadcasts or encrypted data broadcasting services.
- Each encrypted program can be decrypted by means of a smart card having the decryption rights and generating the appropriate decryption keys using digital keys received via the digital reception terminals.
- a return channel such as a telephone network is used to bill or decrement prepaid tokens, then the allocation of temporary rights to the smart card, allowing the user to watch the selected program or film.
- the decryption is done without connection thanks to the keys recovered in the transmitted stream which also contains the encrypted services or programs.
- the service provider has no way of knowing the list of users (or smart cards) who decrypt its programs at all times, and therefore, has no way of knowing if a pirate card is used at a specific time.
- the system according to the present invention aims to remedy this state of affairs. It allows any service provider such as digital television or encrypted information to know at any time, and therefore to effectively control, the group of users of its services. This system allows the supplier to identify all users at all times. Any smart card or pirate system can be instantly identified thanks to the uniqueness of each open session, a mandatory condition for the recovery of keys. The process offers a solution that is more difficult to "hack" than all of the current systems.
- the system consists in controlling access to encrypted digital data or programs broadcast by satellite, cable or digital terrestrial network, by means of a decryption key server to which each reception terminal must connect with a unique identification through a secure channel independent of the transmission channel to be able to use the data or programs transmitted.
- FIG. 1 is a block diagram of an assembly allowing the application of the proposed system.
- the assembly according to Figure 1 consists of a broadcasting station
- the data 5 to be transmitted by the station 1 of the supplier are sent to the satellite network by means of an encrypted data server 6 after passing through a module encryption 7.
- the station 1 also comprises a key server module 8 connected to an authorization controller 9 and connected to the telephone network 10.
- a smart card reader 11 is integrated into the reception terminal 2 or connected to the latter.
- Communication sessions, or “sessions” are opened with the key server 8 which identifies the telephone and smart card numbers 11 characterizing the user and or the receiver's Internet address 2.
- the authorization controller 9 decides or not to provide the decryption keys during the whole session according to the rights of the user.
- the system described can have the drawback of occupying a telephone line for a long time, resulting in a high communication cost and discomfort caused to users having only one telephone line.
- An intermediate solution consists in downloading several keys on each connection in a secure area (for example in the smart card 11 itself) so as to free the line during the use of these keys.
- a connection of a few seconds per hour could be sufficient to load the keys needed during this period.
- GSM Global System for Mobile communications
- the system can allow unsubscribed users to use
- Public terminals or multi-user receivers can allow everyone, unlike decoders located in private homes, access to paid data and services.
- Each user is provided with an access card (chip card for example, which can also serve as a payment card), or an access code and a password, or even a biometric control. allowing access to the desired services on an ad hoc basis, for example in a hotel or department store.
- Each connection makes it possible to manage and control for each a remote account giving more freedom and service to users and more offer, controlled and secure to service providers.
- the system according to the invention can be used in the field of paid software (contracts, licenses) or equipment rental.
- the keys sent online making it possible to keep the software or one of its modules active. For example, part of the software disappears when the keys are not received, making it non-operational,
- the user can either buy pre-credited cards or load a card using an online connection. This card can allow subsequent use of software or hardware without connection.
- a personal computer placed free of charge with the user can only function if the appropriate card has sufficient credit.
- This application can also be associated with an unconnected flow control: to be able to use the hardware or the software, not only the user must have sufficient credit, but during the time of use or a part, he receives data by a downlink with no return path required (satellite reception for example) which unlocks the use of hardware or software.
- the credit card can give a reception system the parameters necessary for filtering unlocking data.
- the user's credit gives the system the possibility and the necessary parameters upon receipt of access codes or passwords issued by a remote system allowing the desired use.
- the system according to the invention can also give rise to applications in the field of totally portable reception tools such as advanced mobile telephone (UTMS reception, advanced matrix display screen), or mobile “decoder-television set”, equipped with a broadcast stream receiver and possibly a mono or bi-directional wireless return channel.
- UTMS reception advanced mobile telephone
- advanced matrix display screen mobile “decoder-television set”
- broadcast stream receiver equipped with a broadcast stream receiver and possibly a mono or bi-directional wireless return channel.
