Abstract
The invention relates to a videodisc player with an identity authentication function, solving the problems of copyright protection of digital music and film and television programs. The videodisc player (1) with an identity authentication function relates to the filed of data safety, electronic technology, wireless radiofrequency and identity authentication and comprises a videodisc player (2) and an authentication card (3), wherein the videodisc player (2) is internally provided with a video and audio playing identity authentication inner core. The invention has the cores that encryption video and audio can be ensured to be only used by a consumer with the relevant authentication card (3) by locking and authentication encryption data in video and audio medium and the authentication card (3) which can not be duplicated, thereby protecting the copyright to the maximum degree. The solving scheme can also be deal with pirate measures occurring in the future through a network updating function.
Description
Technical field
Electronic technology, less radio-frequency/bar codes technique, authentication, data security and copyright protection field.
Background technology
Embedded device, electronic technology, less radio-frequency/bar codes technique, authentication and data encryption and decryption technology
Summary of the invention
What the present invention relates to is a kind of video disc player with identity authentication function (1), and it is made up of the video disc player (2) and the authentication card (3) of built-in audio-visual broadcast authentication kernel.
The copyright protection of digital music and films and television programs is big focuses that the world today pays close attention to.The video disc player of band identity authentication function of the present invention (1), by enciphered data in the audio-visual medium and authentication card (3) are locked and authentication, guaranteed that the consumer that the encryption video-audio data can only be had a relevant authentication card (3) uses, thereby farthest protected copyright, increased very big difficulty to piracy; By the network upgrade function, this solution can also be tackled the following pirate trick that occurs.
Embodiment
One, adopt data encryption technology, making the video-audio data (comprising video display and digital music) of audio-visual medium (for example DVD/CD or Blu-Ray etc. more high storage capacity medium) stored is encrypted state, and common player and playout software can't be discerned and play.This is encrypted as data encryption, and the audio-visual medium that stores enciphered data can carry out the industrialization volume production.Every audio-visual medium all has a digital label or sequence number (for example on packing box, needing to decide on cost).
Two, the video disc player (2) of band authentication function provides an authentication card (3) (for example digital label, rfid card, Smart Card or the like) and apparatus for reading of bar code, and the authentication card (3) that is adopted all has global unique sequence number, is not reproducible.This authentication card (3) is sold (or be integrated in video disc player among) with video disc player (2), and the consumer also can locate purchase/acquisition audio-visual medium dealer.Also have a network interface on the video disc player (2), be used for down loading updating demoder and anti-piracy measure on the one hand, the data in digital label, bar code and the authentication card (3) can be sent in the PC on the other hand, so that in computer, play audio-visual.
Three, the consumer should provide an authentication card (3) (dealer also can provide) when buying digital music or video display disc.The dealer reads the consumer by the audio-visual authoring system of networking and holds the global unique sequence number that authenticates in the card (3), and with it the decruption key of purchasing disc is encrypted, be stored in the digital label of disc then or generate bar code and be affixed on the disc packing.Thus, the disc of sale has promptly formed man-to-man locking relation with the authentication card (3) that the consumer is held, and video disc player (2) will seek out plays required key, must by with the authentication card (3) of this disc locking.
Four, adopt embedded device technology, the video-audio data deciphering playing device that design video disc player (2) is special-purpose.This device is when playing the enciphered data in the audio-visual medium, at first to read the information in the disc digital label (or bar code), because this information is that the sequence number with consumer authentication card (3) is that key is encrypted, next video disc player (2) will be pointed out and be provided corresponding authentication card (3) (or the integrated sequence number of this machine of reading), if utilize the sequence number that therefrom reads can solve correct broadcast key, then the consumer can appreciate relevant program.
Five, this solution itself does not have special anti-copy measure to audio-visual medium, does not therefore increase the cost of making audio-visual medium (disc), and existing industrialization volume production mode is also unaffected.Its cost of digital label that medium attaches is also very low, and can look feelings and select sequence number/bar code mode.Though disc can be duplicated by the bootlegger, authentication card (3) is not reproducible, the uniqueness information of storage wherein not, and video disc player (2) can not be play key, also just can't normal play, thus protected copyright to greatest extent.Simultaneously, because the portable characteristics of authentication card (3) (for example can be integrated in key chain, the mobile phone), therefore the audio-visual disc of encrypting can be gone up at different video disc player (2) easily and play, thereby can not make troubles to the consumer.Because PC also can be obtained the interior data of digital label, bar code and authentication card (3) by video disc player (2), therefore also can play video disc on computers.In addition, video disc player can pass through more new decoder and anti-piracy measure of network interface, thereby makes the copyright protection measure can tackle the pirate trick of innovations in pattern or design.
Description of drawings
Fig. 1 is a functional structure chart of the present invention.Show the video disc player (2) and the authentication card (3) of a built-in audio-visual broadcast authentication kernel among accompanying drawing Fig. 1, the video disc player (1) of the band identity authentication function that their mutual group become the present invention relates to.
Claims (3)
1. be with the video disc player (1) of identity authentication function; form by the video disc player (2) of built-in audio-visual broadcast authentication kernel and not reproducible authentication card (3); its characteristics are; by enciphered data in the audio-visual medium and authentication card (3) are locked and authentication; guaranteed that the consumer that the encryption video-audio data can only be had a relevant authentication card (3) uses; thereby farthest protected copyright; increase very big difficulty to copy right piracy; by the network upgrade function, this solution can also be tackled the following pirate trick that occurs.
2. the video disc player that meets claim 1,
Its characteristics are,
This video disc player (2) has an additional authentication card (3), no matter be to provide separately or be integrated in the video disc player (2), by this authentication card (3), video disc player (2) can lock encrypting video-audio data and this card, and the video-audio data that non-this card is relevant can't be play.
3. the video disc player that meets claim 1 or 2,
Its characteristics are,
This video disc player (2) has a computer network interface, is used for down loading updating demoder and anti-piracy measure on the one hand, can will be sent to PC for information about on the other hand, and this is audio-visual to supply its broadcast.
