Best Mode for Carrying Out the Invention

[42] Below, with the attached figures as a reference, the correct operation of the method of trading digital rights management based digital contents of this invention is explained in detail.

[43]

[44] Figure 1 is an organization chart of the operation of the method of trading digital rights management based digital contents.

[45] First, before explaining the method of trading digital rights management based digital contents, the technology of digital rights management (DRM) must be understood.

[46] As a technology devised to protect the intellectual property rights of digital contents, though the forms of this technology can vary, the basic concept is that the special information of digital contents can be read and written for the purpose of when the digital content is circulated through wire or wireless internet, that information can be traced and managed.

[47] Therefore, copying or lending digital content at will can be originally seen as impossible.

[48]

[49] In reference to figure 1, by using a personally owned multimedia terminal device

(110), the consumer can connect to a digital contents trade server (300), in charge of trading digital contents, through a wire or wireless communications network at anytime from anywhere.

[50] A digital contents trade server (200) provides to the consumer various information and tools necessary for digital contents trading, and a digital contents trade server (300) is connected to various databases which are contents service means (500).

[51] Contents service means include a digital contents database (DB) server (510) for the purpose of digital contents sales, a consumer DB server (520) for consumer management, and a charge payment DB server (530) for the charging and payment from trade.

[52] Also, on the digital contents trade server (300) a digital contents management means (400), which has the technology to directly manage and reference digital contents to consumer user information or history, is connected.

[53] The digital contents management supervising means (400) includes a DRM server for digital rights management (410), a KMID server (420) related to standard code, a watermark server (430) related to illegal copying prevention technology, and a fingerprint server (440) related to the concept of a fingerprint of public key. The DRM server (410), KMID server (420), watermark server (430), fingerprint server (440), and PKI server (450) are connected to the digital contents trade server (300), so when the consumer trades digital contents, the reciprocal information is always given and

received.

[54] Therefore, the digital contents trade server (300) mediates between the contents service means (500) and the digital contents management supervising means allowing the formation of reselling transaction, direct transaction, mediated transaction, and auction transaction of digital contents.

[55] Therefore, digital contents can be traded directly or indirectly between consumer multimedia terminal device (110) and another consumer multimedia terminal device, consumer multimedia terminal device and business multimedia terminal device (120), or business multimedia terminal device (120) and another business multimedia terminal device by reselling transaction, direct transaction, mediated transaction, and auction transaction methods.

[56] The reselling transaction, direct transaction, mediated transaction, and auction transaction methods of digital contents between consumer multimedia terminal device (110) and another consumer multimedia terminal device are P2P (peer to peer); the reselling transaction, direct transaction, mediated transaction, and auction transaction methods of digital contents between consumer multimedia terminal device (110) and business multimedia terminal device (120) are B2C (business to customer), the reselling transaction, direct transaction, mediated transaction, and auction transaction methods of digital contents between business multimedia terminal device (120) and business multimedia terminal device (120) are B2B (business to business), but not limited to the above methods.

[57] Furthermore, the digital contents purchased by the consumer includes sound, music, still images, or video clips, and all software managed by the digital contents management supervising means (500).

[58]

[59] Figure 2 is the flow chart of the resale transaction process of digital contents under operation of the method of trading digital rights management based digital contents.

[61] Next, in order to sell the digital contents, the consumer registers the digital contents on the digital contents trade server (300) and the linked reselling transaction site (stage S 102).

[62] Next, the digital contents registered in stage S 102 is evaluated of its validity on the

DRM server (410), KMID server (420), watermark server (430), fingerprint server (440), and PKI server (450) of the digital contents management supervising means

(400) (stage S 103).

[63] Next, the digital contents evaluated for its validity in stage S 103, the proper ownership, based on the information and background on the digital contents DB server (510) and consumer DB server (520), is granted to the registered consumer by the DRM server (410) or PKI server (450) of the contents management supervising means (400) (stage S 104).

[64] Next, when a purchase request is made for the digital contents on the reselling transaction site linked to the digital contents trade server (300), the purchase contract about the utilization condition of the digital contents, such as utilization frequency, utilization term, utilization software, utilization device, utilization subject, utilization place, and utilization method, is made with the purchaser (stage S 105).

[65] Next, the digital contents purchased through the purchase contract is payed for on the charge payment DB server (530) that is linked to the digital contents trade server (300) (stage S 106).

[66] Next, the purchaser is granted utilization rights of the purchased digital contents which was payed for in stage S 106 (stage S 107).

[67] Next, excess digital contents after usage under the contract utilization conditions from stage S 105 are requested for resale through the reselling transaction site that is linked to the digital contents trade server (300) (stage S 108).

[68] Next, the digital contents utilization history of the digital contents requested for resale in stage S 108 is referenced on the consumer DB server (520) that is linked to the digital contents trade server (300) (stage S 109).

[69] Next, based on the referenced utilization history in stage S 109, the remaining utilization rights of the digital contents are analyzed on the contents service means (500) and digital contents management supervising means (400) as well as the reciprocally connected digital contents trade server (300) (stage SI lO).

[70] Next, the if the utilization rights of the analyzed digital contents in stage SI lO are valid, the approval of the resale request in stage S 108 is decided on the digital contents trade server (300) (stage Si l l).

[71] Next, during the determination for resale of digital contents in stage Si l l, the amount of money calculated by a separately appropriated method is sent to the account of the requester, who is also the consumer, or the payment can be made by mileage, points, and items (stage S 112).

[72] Also, it is appropriate to include a stage in which when a resale request is rejected during the approval process of resale requests in stage Si l l, the rejection notification for the digital contents is sent through the digital contents trade server and the linked resale transaction site.

[73]
