That is, the signal quality of the copied digital signal is identical to that of the original. Therefore, the software is vulnerable to a copyright infringement.
[3] In order to prevent the software stored in the storage media from an illegal duplication, a scheme wherein the signal stored in the storage media is distorted, or a scheme wherein a special marking is stored in a storage area to which a normal user cannot access. However, a high-priced special equipment should be used to employ theses schemes.
[4] A scheme wherein a serial number or a password should be inputted in order to execute software has been developed to prevent the illegal duplication. However, it is disadvantageous in that the serial number and the password may be illegally generated.
[5] A scheme wherein a copy protection device is added may be employed. For instance, the copy protection device having therein an information required for executing the software is connected to a parallel port of a computer. The computer then inspects the parallel port to detect a presence of the copy protection device when the software is executed.
[6] However, when the copy protection device is used, a cost for manufacturing the software package is increased. In addition, a user must install the copy protection device. Moreover, since the number of the copy protection device that may be installed in the computer is limited, the illegal duplication cannot be efficiently prevented as the number of the software increases.
[7] Alternately, a scheme wherein the user downloads the software via the Internet and obtains an authentication to use the software may be possible.
[8] However, even when the software is downloaded via the Internet, the user may illegally copy the software. For instance, the user may generate an illegal authentication information to use the software.
[9] On the other hand, the storage media such as a DVD, a blu-ray disc and a HD-DVD having therein a movie content as well as the software may be illegally copied by the user.
[10] A data in a form of a digital file stored in the storage media or downloaded via the
Internet such as the software and a multimedia content is hereinafter referred to as "digital content".
[11] An apparatus capable of carrying out a signal processing in order to reproduce or execute the digital content is hereinafter referred to as "digital content processing apparatus"
[12] The digital content processing apparatus may be a computer executing the software.
The digital content processing apparatus may also be a playback apparatus for reproducing the multimedia content such as a movie stored in the storage media. In addition, The digital content processing apparatus may be a playback apparatus capable of storing and reproducing the digital content such as a portable MP3 player.
[13] The digital content processing apparatus herein is capable of reading or storing the digital content and of executing or reproducing the digital content.

[80] Referring to Fig. 2, the digital content processing apparatus 100 in accordance with the present invention comprises a radio frequency identification data reader 110, a copyright manager 130 and a signal processor 150. Still referring to Fig. 2, the digital content processing apparatus 100 may further comprise a data storage 170. In addition, the digital content processing apparatus 100 may further comprise a user information storage (not shown).
[81] The radio frequency identification data reader 110 reads the copyright verification data of the digital content from the radio frequency identification tag 250 of Fig. 1.
[82] Referring back to Fig. 1, the radio frequency identification data reader 110, for instance, reads the copyright verification data from the radio frequency identification tag 250 attached to the digital content processing apparatus 100.
[83] The radio frequency identification data reader 110 transmits the power and the request signal to the radio frequency identification tag 250 and may receive the copyright verification data from the radio frequency identification tag 250.
[84] The radio frequency identification data reader 110 may read the copyright verification data in below-described cases. [85] The radio frequency identification data reader 110 may read the copyright verification data when a power is applied to the digital content processing apparatus 100 and the digital content processing apparatus 100 starts to operate. When the power is applied to the digital content processing apparatus 100, the radio frequency identification data reader 110 reads the copyright verification data from the radio frequency identification tag 250. Therefore, the digital content processing apparatus 100 may carry out a copyright management based on the copyright verification data from an initial operation thereof.
[86] For instance, when the digital content is an operating system software such as
Microsoft Windows, the digital content is executed when the power is applied to the digital content processing apparatus 100.
[87] Therefore, it is preferable that the radio frequency identification data reader 110 reads the copyright verification data from a moment the power is applied.
[88] In addition, the digital content processing apparatus 100 may carry out the copyright management continuously during an execution of the software.
[89] Therefore, it is preferable that the radio frequency identification data reader 110 reads the copyright verification data continuously during the execution of the software.
[90] Alternately, when the digital content is stored in the compact disc, the digital content processing apparatus 100 may carry out the copyright management by reading the copyright verification data when the digital content stored in the compact disc is read or executed.
[91] For instance, when the digital content stored in the compact disc is duplicated to another compact disc and is used in another digital content processing apparatus, the digital content is still executable in accordance with the conventional technology. However, in accordance with the present invention, the radio frequency identification data reader 110 reads the copyright verification data every time the digital content stored in the compact disc is read or executed such that the digital content processing apparatus 100 may carry out the copyright management. Therefore, the digital content cannot be executed in the digital content processing apparatus that is not capable of reading the copyright verification data stored in the radio frequency identification tag 250.
[92] Moreover, even after the digital content is stored in the digital content processing apparatus 100, the radio frequency identification data reader 110 reads the copyright verification data for the digital content such that the digital content processing apparatus 100 may carry out the copyright management based on the copyright verification data. Therefore, illegal copying and use of the digital content is minimized.
[93] Storing the digital content in the digital content processing apparatus 100 includes, for instance, an installation of the software and storage of a multimedia content. [94] The copyright manager 130 determines an authenticity of the digital content by comparing the copyright information included in the digital content with the copyright verification data.
[95] That is, the copyright manager 130 determines the digital content to be authentic when the copyright verification data conforms to the copyright information.
[96] For instance, in case that the copyright verification data and the copyright information have a same format, the digital content is determined to be authentic only when the copyright information included in the digital content is identical to the copyright verification data read by the radio frequency identification data reader 110. The copyright verification data may correspond to the copyright information by one- to-one.
[97] In addition, in case that the copyright verification data or the copyright information is encrypted, the copyright verification data and the copyright information may be compared after the copyright manager 130 decrypts the copyright verification data or the copyright information.
[98] Moreover, in case that the authenticity of the digital content is verified by comparing the copyright verification data and the copyright information having different formats, the copyright manager 130 may determine the authenticity of the digital content by comparing the copyright verification data and the copyright information.
[99] The signal processor 150 carries out a signal processing for an execution of the digital content based on a result of the determination of the authenticity.
[100] That is, the signal processor 150 carries out the signal processing for the execution of the digital content only when the copyright manager 130 verifies the authenticity of the digital content.

[103] Preferably, the data storage 170 stores the digital content only when the digital content is determined to be authentic.
[104] That is, when the digital content is stored in the data storage 170, the radio frequency identification data reader 110 reads the copyright verification data from the radio frequency identification tag 250. The copyright manager 130 then compares the copyright information included in the digital content with the copyright verification data read by the radio frequency identification data reader 110 to determine the authenticity. The signal processor 150 controls the storage of the digital content in the data storage 170 based on the result of the determination of the authenticity. For instance, when the digital content is determined to be inauthentic, the signal processor 150 controls the data storage 170 to not to store the digital content.
[105] In addition, the signal processor 150 may read the digital content from the data storage 170 after the digital content is stored in the data storage 170.
[106] When the digital content is read from the data storage 170, it is preferable that the signal processor 150 reads the digital content only when the digital content is determined to be authentic.
[107] The radio frequency identification data reader 110 reads the copyright verification data from the radio frequency identification tag 250. The copyright manager 130 then compares the copyright information included in the digital content stored in the data storage 170 with the copyright verification data read by the radio frequency identification data reader 110 to determine the authenticity. The signal processor 150 reads the digital content from the data storage 170 based on the result of the determination of the authenticity.
[108] For instance, when the digital content is determined to be inauthentic, the signal processor 150 does not read the digital content from the data storage 170.
[109] On the other hand, the copyright verification data may further include an execution level information of the digital content.
[110] The execution level information defines a level of execution for a software having various functions.
[I l l] For instance, a first execution level information for a word processing software may be defined to allow carrying out an entire function of the word processing software, and a second execution level information for the word processing software may be defined to allow carrying out a partial function of the word processing software such as reading a document file of the word processing software.
[112] When the copyright verification data including the second execution level information is read from the radio frequency identification tag 250, the digital content processing apparatus 100 may carry out the signal processing in a manner that the word processing program only reads the document file.
[113] As described above, the signal processor 150 may carry out the signal processing for the execution of the digital content based on the execution level information as well as the result of the determination of the authenticity by the copyright manager 130.
[114] The execution level information may also be included in the copyright information of the digital content. When the copyright information includes the execution level information, the signal processor 150 may carry out the signal processing for the execution of the digital content based on the execution level information included in the copyright information of the digital content as well as the result of the determination of the authenticity by the copyright manager 130. [115] Although not shown, the digital content processing apparatus 100 in accordance with the present invention may further comprise the user information storage.
[116] A user information is an information on a user of the digital content processing apparatus 100, which may include a gender, an age and a nationality of the user. The user information may include an identification information of the digital content processing apparatus 100.
[117] For instance, when the digital content is for an adult, the digital content should not be provided to an under-aged person.
[118] Accordingly, the copyright verification data or the copyright information may include a rating information for the digital content. For Instance, the copyright verification data or the copyright information may include the rating information divided into "for adults"and "for all ages".
[119] When the copyright verification data or the copyright information includes the rating information, the signal processor 150 may carry out the signal processing for the execution of the digital content based on a result of a comparison between the user information of the user information storage and the rating information.
[120] On the other hand, the radio frequency identification data reader 110, the copyright manager 130 and the signal processor 150 is embodied as a chip.
[121] For instance, the radio frequency identification data reader 110, the copyright manager 130 and the signal processor 150 may be embodied in a single processor chip such as a CPU and an MCU.
[122] The single processor chip including the radio frequency identification data reader 110, the copyright manager 130 and the signal processor 150 may be used as a signal processing device in the digital content processing apparatus 100 in a form of a personal computer, a laptop computer, a PDA, a mobile communication terminal and a PMP. Therefore, the copyright of the digital content may efficiently protected. Mode for the Invention
