2. Description of the Related Art
In general, audio and video files can be downloaded from a server and played in a DVD or CD player by means of a simple security check according to a prior art. However, the security check may be skipped by users, and thus DVD or CD publishers cannot request users to pay for the downloaded files and thus the unauthorized use of DVD or CD media becomes more and more.
Furthermore, at present, a user can not get an identification code from the supplier when he/she buys computer software(s), DVD or CD through a network; therefore, the supplier can not effectively stop the user from illegally copying the computer software(s), DVD or CD, such that the benefit of the supplier will be harmed. Furthermore, the computer software(s), DVD or CD does not have the read-once function; therefore, its sale price remains higher, thus user will be less willing to buy the legal computer software(s), DVD or CD.
At present, the DVD has developed some new specifications, such as Blu-ray DVD and HD DVD, wherein, the Blu-ray DVD is the standard of the next generation optical disk format. Due to the quality requirement of the multi-media from human is increasing day by day, the Blu-ray DVD could be used to store the high resolution audio, video and high capacity data, while the HD DVD, similar to the Blu-ray DVD, is also the format of next generation optical disk.
At present, there are systems or solutions that can solve the problem of protecting DVD or CD from unauthorized copying. For example, U.S. Pat. No. 5,991,403 issued to Aucsmith, et al disclosed a method for encoding MPEG compatible video data for subsequent compression that comprises detecting a plurality of frames of video data organized as a GOP, generating an encryption key for the GOP, and encrypting the video data using GOP-synchronized substitution, transposition, and rotation transformations that are parameterized by offsets derived from the generated encryption key.
U.S. Pat. No. 5,915,018 issued to Aucsmith, et al disclosed a cryptographic system and method for secure distribution and management of cryptographic keys for use in a DVD copy protection scheme. A DVD disc having compressed, encrypted content written on a first portion of the disc, and the content encryption key, itself encrypted with a second key and written out of band on a second portion of the disc is used to provide content, key, and control information to a DVD player.
The U.S. Pat. No. 5,991,403 disclosed a method for encoding MPEG compatible video data for subsequent compression; while the U.S. Pat. No. 5,915,018 disclosed a cryptographic system and method for secure distribution and management of cryptographic keys for use in a DVD copy protection scheme. However, the prior arts could not provide a system or method used for a portable electronic device, for example but not limited to a portable media play device with a display device, such as a LCD for legally playing computer software(s), audio file(s) or video file(s) in the CD, DVD. Furthermore, the computer software(s), DVD or CD does not have the read-once feature; therefore, the sale price of the CDs or DVDs could not be reduced.
Therefore, it is a primary objective of the present invention to overcome the foregoing shortcomings of the prior art by providing a purchasing and copy protecting method for a digital content, which will check whether its own identification code, the identification code provided from a supplier, the identification code of a medium and the identification code of a storage device are matched or not; if yes, then the portable electronic device can read the medium; if not, then the portable electronic device can not read the medium in the device.
Another objective of the present invention is to overcome the foregoing shortcomings of the prior art by providing a purchasing and copy protecting method for a digital content, which provides a read-once medium for reducing the sale price of the CDs or DVDs.
Another objective of the present invention is to overcome the foregoing shortcomings of the prior art by providing a purchasing and copy protecting method for a digital content, which will read the medium and delete the content of the medium after reading the medium, so as to resolve the problem of computer software(s), DVD or CD illegal copying.
Another objective of the present invention is to overcome the foregoing shortcomings of the prior art by providing a purchasing and copy protecting method for a digital content, user can give the storage device or medium to other user as a gift or sell the storage device or medium to other user and will not affect the right of the computer software(s), DVD or CD publisher.
