Definitions
- the invention relates to a method and system for authenticating a disc over the Internet.
- Copying protection has become an urgent issue to content providers. Each year billions of dollars have been lost by the industry due to piracy. To counter the piracy, various techniques have been proposed such as watermarking, the Contents Scrambling System (CSS), wobble, etc. Digital watermarking is a technique in which watermarks are embedded into audio/video data to indicate whether or not the contents are copyrighted. Watermarks can be easily detected, but can hardly be removed without degrading the content quality. This technique, however, is primarily used for copyright verification, rather than for copying protection.
- the CSS is a copying protection system developed for protecting against illegal copying of
- the present invention provides a disc player that authenticates a disc via the Internet.
- the player upon insertion of a disc into a player, the player reads a disc identification (ID) on the disc. The player then sends a registration request with the disc ID to a server over the Internet for obtaining an authentication key for playing the disc, upon proper registration of the disc by the server.
- the server To properly register the disc, the server first determines whether the disc ID is included in its database. If so, the server will then check whether the disc has already been registered. If it has not, the server will send back an encrypted authentication key to the player to enable it to play the disc.
- the server Upon proper registration of the disc, the server will set a registration status associated with the disc to prevent any subsequent unauthorized registrations for the same disc. If either the disc ID is not included in the server database or the disc has already been registered, the server will send back a failed registration code to the player that will then reject the disc.
- a pre-selected disc may be properly registered for a pre-determined number of times.
- the server will keep track of the number of registrations with respect to that disc.
- FIG. 1 shows an overview of disc copying prevention through Internet authentication in accordance the invention
- FIG. 2 is a simplified diagram illustrating the operation of a disc player in accordance with one embodiment of the invention
- FIG. 3 is a flowchart diagram illustrating a disc registration process performed by a disc player in accordance with one embodiment of the invention.
- FIG. 4 is a flowchart diagram illustrating a disc registration process performed by a web server in accordance with one embodiment of the invention.
- FIG. 1 shows an overview of disc copying prevention through Internet authentication in accordance with the invention.
- the player When a new optical disc 10 is inserted into a disc player 20, the player will register the disc by sending an associated unique disc ID to a web server 30 via the Internet.
- Web server 30 stores a large database maintained by a content provider of the disc, which contains disc IDs for numerous released disc titles. Before the content provider releases a new disc title, all the unique disc IDs associated with this new title will be added to the database, and a registration status associated with each of these unique disc IDs is set to "unregistered".
- the web server Upon proper registration of the disc, the web server will send back an authentication key to enable the player to play the disc. In this way, the copyright of the disc is verified.
- a first option is to store the disc ID in the Burst Cutting Area (BCA) of a disc.
- BCA Burst Cutting Area
- the disc ID can .be scrambled and embedded into a long series of random numbers to confuse hackers, and only the content provider knows how to extract it.
- a second option is, for each disc in a distribution batch, the content provider can embed the disc ID in a program stream and store the disc ID at a particular location on the disc. The web server knows where to find the disc ID and will fetch the disc
- a third option is to store the disc ID on the clamp area of the disc.
- a read-out device needs to be added to the optical pick-up unit (OPU) of the player in order to read the disc ID on the clamp area.
- OPU optical pick-up unit
- the authentication key Once the authentication key is received by the player, it can be used as a decryption key to decrypt the protected contents on the disc. Additionally, in order to protect the information exchanged between the web server and the player from being illegally intercepted or cracked, encryption/decryption measures may be applied to the disc ID and to the authentication key before they are sent out.
- FIG. 2 is a simplified diagram illustrating the operation of a disc player 20 in accordance with one embodiment of the invention.
- Player 20 may be an operating system independent, stand-alone device with an Internet connection, e.g., a Web DVD player as defined by the DVD Forum, which is an industrial consortium (http://www.dvdforum.org).
- Player 20 may also be a device in a laptop computer or a desktop PC.
- Player 20 includes a flash memory 22, which stores encrypted private data of the player including disc IDs and their associated authentication keys, and a codec 26, which decodes the encrypted private data.
- the disc ID is sent to the web server for registration.
- an authentication key is sent back and stored in flash 22 along with the associated disc ID.
- the authentication key is decoded by codec 26 to enable the player to play disc 10.
- the disc ID will be searched by the player from flash memory 22 to find the associated authentication key.
- the authentication key will then be retrieved and decoded by codec 26 to enable the player to play disc 10, without requiring further authenticating the disc via the Internet.
- FIG. 3 is a flowchart diagram illustrating a disc registration process 100 performed by the disc player in accordance with one embodiment of the invention.
- the player Upon insertion of the disc into the player, the player will read the disc ID (step 102) and search an internal flash memory to find a matching disc ID (steps 106). If a matching disc ID is found, the associated authentication key is retrieved and decoded (step 114), and the player will play the disc (step 116). On the other hand, if a matching disc ID is not included in the flash memory because the disc is played for the first time, the player will send the disc ID and a registration request to a web server (step 122).
- the web server When the web server receives the registration request with the disc ID from the player, it will check, in a disc ID database, a registration status associated with the disc ID received. If the disc ID is included in the database and has not yet been registered, the web server will send back a response with the authentication key to the player. In the meantime, the web server will set the associated registration status to "registered". On the other hand, if the disc ID is not included in the database or the disc has already been registered, the web server will assume that the disc is not an authentic one and will send back a response to the player without the required authentication key. A more detailed disc registration process performed by the web server will be described below in conjunction with FIG. 4.
- the player after receiving a response from the web server (step 126), the player will determine whether the response includes an authentication key (step 132). If the authentication key is included, it will be stored in the player and then decoded (step 136) to enable the player to play the disc (step 116). By storing the authentication key in the player, the disc needs not to be registered again when it is subsequently played. By contrast, if the authentication key is not included in the response received from the web server, the player will refuse to play the disc (step 142), and notify the user (step 146).
- FIG. 4 is a flowchart diagram illustrating a disc registration process 200 performed by the web server in accordance with one embodiment of the invention.
- the server Upon receiving the disc ID from the player (step 202), the server searches through a database (step 206) to determine whether a matching disc ID is included (step 212). If there is no matching disc ID, the server will send back a failed registration code to the player (step 216). If, however, a matching disc ID is successfully found in the database, the server will next determine whether the disc has already been registered (step 222). If it is already registered, the server will also send back a failed registration code to the player (step 216). On the other hand, if the disc has not yet been registered, the server will generate an authentication key (step 226), set a registration status associated with the disc ID to "registered" (step 232), and send back the authentication key to the player (step 236).
- the web server can pre-store authentication keys associated with the pre-defined disc IDs in a database. When it receives a registration request with a legitimate disc ID, it will search for a corresponding authentication key from the database and send it back to the disc player. In another way, when the web server receives a registration request with a disc ID, it will generate a corresponding authentication key by running a software routine and then send it back to the disc player.
- a disc of home edition may include only one license and can be registered only once with the web server to allow only a specific player to play the disc.
- a disc of commercial edition may include multiple licenses and can be registered a predetermined number of times with the web server to allow different players to play the disc. This allows a movie rental company to rent a commercial movie title to a specific number of customers.
- the use of discs with the different editions is monitored by the web server of the content provider.
- Table 1 illustrates an exemplary format of a disc ID database in the web server. In this table, disc ID1 and disc ID2 each represent a home edition and can be registered only once, while disc ID3 represents a commercial edition and can be registered N times. Table 1 Exemplary format of a disc ID database in the web server
