The storage unit 70 may also be a storage device such as a NAS (Network Attached Storage).

  The communication unit 52 communicates with other devices via the network NW. The purchasing unit 54 purchases the right to browse the electronic content from the user in response to the user's request. The purchase unit 54 determines the purchase price for the purchase, and pays the determined purchase price to the user. The invalidation unit 56 invalidates the browsing right purchased by the purchase unit 54. The invalidation unit 56, for example, invalidates the browsing right by transmitting an invalidation request to the license management device 80.

  The price request unit 58 transmits a request for payment of the price to the content sales apparatus 30 in response to the purchase of the browsing right by the purchase unit 54. Then, the price request unit 58 acquires the price corresponding to the purchase from the content sales apparatus 30.

  The statistical processing unit 60 performs statistical processing based on information acquired from other devices such as the content selling device 30 and processing results of the own device. The processing result is transmitted to, for example, the content selling apparatus 30. Further, the statistical processing unit 60 derives the user's action history or the distribution attribute of the electronic content based on the browsing right invalidated by the invalidating unit 56 and the attribute of the user who has sold the browsing right.

  The flow attribute is, for example, information indicating what kind of attribute the electronic content is purchased or sold to a user, information indicating how long the electronic content is sold after being purchased, and information on the purchased user It is information etc. which shows how much the user is selling among them. The statistical processing unit 60 transmits, for example, the flow information to the content sales apparatus 30 or the publisher apparatus 100. The device on the receiving side uses the received flow information for marketing.

  The storage unit 70 stores, for example, purchase history information 72, user information 74, and statistical information 76. The purchase history information 72 is, for example, information such as a content ID of the purchased electronic content, a user ID of selling the purchased electronic content, an amount of money for purchasing the electronic content, and the like. The user information 74 is information indicating a user ID or attribute registered in advance. The information indicating the attribute is, for example, the age, sex, residence area, occupation, etc. of the user.

  The statistical information 76 includes the statistical result of the statistical processing unit 60. Also, the statistical information 76 may include information acquired from another device such as the content selling device 30 or the like.

License Management Device
FIG. 5 is a diagram showing a functional configuration of the license management device 80. As shown in FIG. The license management device 80 includes, for example, a communication unit 82, a license management unit 84, and a storage unit 90. The storage unit 90 stores, for example, management information 92 and bibliographic information 94.

  The communication unit 82 communicates with other devices via the network NW. When the license management unit 84 acquires the request for setting the browsing right from the content sales apparatus 30, the license management unit 84 adds a field of one browsing right to the management information 92. FIG. 6 is a diagram showing an example of the management information 92. As shown in FIG. The management information 92 is information in which a license ID, a shop ID, a user ID, and a status are associated with the content ID. The status is information indicating whether the browsing right has been purchased. Further, in the management information 92, electronic content is stored in association with the content ID.

  When acquiring the request for setting the browsing right, the license management unit 84 associates the content ID with the content of the license ID, the store ID, the user ID, and the status. In addition, when the license management unit 84 acquires, from the content purchase device 50, the information requesting the invalidation of the browsing right, for example, it extracts the field that matches the content ID and the user ID included in the request, and deletes the field. To invalidate the viewing rights. In addition, the license management unit 84 requests the terminal device 10 to delete the browsing key corresponding to the invalidated browsing right. Thereby, the content application 22 of the terminal device 10 deletes the browsing key for which the deletion request has been made. In addition, the license management unit 84 may request the content selling apparatus 30 to delete the electronic content for which the browsing right has been invalidated. In this case, the content selling apparatus 30 deletes from the content information 42 the electronic content for which the browsing right has been invalidated.

  The bibliographic information 94 is, for example, a book title, the number of pages of the book, management information (ISBN code) for managing the book, and the like. The license management unit 84 refers to the management information 92 and the bibliographic information 94, and transmits information of electronic content for which the setting of the browsing right can be set to the content sales apparatus 30.

  The publisher device 100 provides electronic content to another device.

[Process of content distribution system]
FIG. 7 is a conceptual view showing processing executed by the content distribution system 1. In addition, the order of the process demonstrated below is an example, and may be changed suitably.

  First, the publisher device 100 registers electronic content in the license management device 80 (1). The license management device 80 stores the registered electronic content in the storage unit 90 and prepares for processing such as purchase. Next, when the content selling apparatus 30 receives the purchase request for the browsing right of the electronic content transmitted by the terminal device 10 (2), the content selling apparatus 30 communicates with the license management apparatus 80 to set the browsing right (3), browsing The payment for the setting of the right is paid to the publisher device 100 (4). Then, the content selling apparatus 30 enables browsing of the electronic content for which the browsing right is set (5).

  When the content purchase device 50 receives a request to sell the right to browse the electronic content transmitted by the terminal device 10 (6), the content purchase device 50 communicates with the license management device 80 to invalidate the right to browse (7). Next, the content purchase device 50 pays the terminal device 10 a purchase amount (a price) for the sale of the right to browse the electronic content (8). Note that the content purchase device 50 does not use cash as a compensation for the sale of the right to browse the content, instead of using the terminal device 10 with points or coupons that can be used at the seller's bookstore (for example, shopping via the content sales device 30). You may pay. Further, the payment of the above-mentioned compensation may be handed over without using the terminal device 10. For example, the content purchase device 50 causes the storage unit 70 to store information on the user, the value to be paid to the user, and the amount of the value. Then, the administrator etc. of the content purchase device 50 refers to the information stored in the storage unit 70 and pays the user of the terminal device 10 who has visited the bookstore (or affiliated store of the bookstore) managing the content sales device 30. Pay. Further, as a price, a discount may be implemented in shopping at a bookstore.

  Next, the content selling apparatus 30 transmits purchase information indicating that the browsing right has been purchased to the content selling apparatus 30 (9). When the content selling apparatus 30 receives the purchase information, the content selling apparatus 30 pays the content purchase apparatus 50 a price corresponding to the purchase (10). The purchase information includes a content ID of a browsing right, a license ID, and a user ID. The content selling apparatus 30 may delete the electronic content corresponding to the purchase information from the storage unit 40 with reference to the purchase information.

  As described above, the content purchase device 50 can obtain the price corresponding to the purchase from the content sales device 30 by purchasing the browsing right of the electronic content from the user. Then, the content purchase device 50 can return a part or all of the obtained value to the user as a price for the sale of the right to browse the electronic content. In this way, the content purchase device 50 purchases the browsing right and returns the value acquired from the content selling device 30 to the user, thereby giving the opportunity for the user to purchase the new electronic content browsing permission from the content selling device 30. Can be given. As a result, distribution of electronic content can be promoted.

  FIG. 8 is a flowchart showing a flow of processing executed by the content purchase device 50. First, the purchase unit 54 determines whether a request for purchasing a browsing right has been received from the user (step S100). When the purchase request is received, the purchase unit 54 determines the purchase amount of the browsing right (step S102). The purchase amount may be a preset amount, or may be an amount based on the value acquired from the content sales apparatus 30, an attribute defined by the user, the type of electronic content, or the like. Next, the invalidation unit 56 transmits a request for invalidation of the browsing right to the license management device 80 (step S104).

  Next, the invalidation unit 56 determines whether information indicating that the browsing right has been invalidated is returned from the license management device 80 (step S106). When the information indicating that the browsing right is invalidated is returned, the purchase unit 54 pays the user the purchase amount for the purchase of the browsing right (step S108).

  Next, the price request unit 58 transmits purchase information indicating that the user has purchased the browsing right to the content sales apparatus 30 (step S110). Next, the price request unit 58 determines whether the price corresponding to the purchase has been acquired from the content sales apparatus 30 (step S112). When the price corresponding to the purchase is obtained, the price request unit 58 manages the obtained price (step S114). Thus, the processing of one routine of this flowchart ends.

  As described above, the content purchase device 50 can purchase the browsing right from the user, and can obtain the value from the content selling device 30 by purchasing the browsing right. In the process described above, the price is described as being paid each time the browsing right is purchased, but the price may be added up every predetermined period and paid every predetermined period.

  In the process described above, the content purchase device 50 obtains the price from the content sales device 30 after paying the purchase price to the terminal device 10, but instead (or in addition), the content purchase The price request unit 58 of the device 50 may charge the content seller the price corresponding to the purchase of the browsing right, and determine the price for the purchase to be paid to the user within the charged price range. In addition, consideration may be determined within the range of the value scheduled to be charged. The value request unit 58 is an example of the “compensation determination unit”.

[Set value]
For example, the value corresponding to the browsing right purchased from the user is determined by the following process. Also, the purchase amount to be paid to the user who sold the browsing right may be determined based on this value, or conversely, the value may be determined based on the purchase amount.

  The price determination unit 36 determines the price, for example, based on a part or all of the frequency, the number, or the number of circulations of the browsing right that has been revoked for each electronic content. These pieces of information are provided, for example, by the statistical processing unit 60 of the content purchase device 50, and are stored in the storage unit 40 of the content sales device 30 as the price determination information 48.

  FIG. 9 is a diagram showing an example of the content of the price determination information 48. As shown in FIG. The price determination information 48 is, for example, information in which the frequency of invalidation of the browsing right, the number of invalidation times, the number of copies, and the resale rate are associated with each content ID (for example, electronic content of the same title). The frequency of invalidation refers to the number of times of invalidation in a certain period. The resale rate is the rate at which the browsing rights are purchased again after the browsing rights are revoked.

For example, the value may be derived based on the following formula (1). For example, in the formula (1), "C" is a value, "K" is a set positive coefficient, "K1" is an index indicating the frequency of invalidation, "K2" is an index indicating the number of invalidation, " “K3” is an index indicating the number of circulations, and “K4” is an index indicating the resale rate. For example, the lower the frequency of invalidation, the lower the frequency of invalidation, the smaller the number of copies of K3, and the higher the resale rate, the larger the K3. Set to
C = K (K1 + K2 + K3 + K4) (1)

  FIG. 10 is a diagram showing another example (1) of the content of the price determination information 48A. The price determination information 48A is, for example, information in which the type of electronic content, the issue date, the sales, the distribution degree, and the attention degree are associated with each content ID (for example, electronic content having the same title). The type of electronic content is information indicating a collection classified as a weekly magazine, a monthly magazine, a newspaper, books of interest, academic books, and the like. The sales are sales generated due to the electronic content, and may be an amount obtained by multiplying the selling number by the selling number, or may include the amount sold in the second hand. The degree of distribution is an index that is estimated to be distributed in the market for electronic content (and books with the same content as electronic content) for trading. The distribution degree is estimated based on, for example, the number of electronic contents sold at the shopping site. The attention degree is the attention degree derived based on the information of the website, etc., and the larger the number associated with the language in which the keyword etc. related to the target electronic content shows a positive expression, the larger The smaller the number associated with languages that show negative expressions, the smaller.

For example, the value may be derived based on the following formula (2). For example, in the equation (2), "C" is a value, "K #" is a set positive coefficient, "K11" is an index based on the type of content and date of issue, and "K12" is associated with sales. The index “K13” is an index associated with the distribution degree, and “K14” is an index associated with the attention degree. When the type of electronic content is a periodical issue (daily newspaper, weekly magazine, monthly magazine, etc.), for example, the index “K11” is set to be lower as time passes from the time of issuance. In addition, when the type of the electronic content is a book, for example, “K11” may be fixed, or, for example, “K11” may be set high when it is a predetermined period or more before the present. Also, for example, the higher the sales of “K12”, the smaller the distribution degree of “K13”, and the larger the attention degree of “K14”, the larger the degree of distribution.
C = K # (K11 + K12 + K13 + K14) (2)

  The price determination unit 36 may determine the price based on the attribute of the user. For example, as the age of the user is lower, the price is set higher. In addition, the value may be set high in the case of purchasing the browsing right from a user such as a predetermined age, sex, residence area, occupation, etc. in a certain period. Also, if the user's occupation is a student, the value may be set high.

  Further, the price determination unit 36 may determine the price based on an index indicating the degree of purchase or sale of the browsing right for each user, for example, with reference to the price determination information 48B shown in FIG. In this case, the index is, for example, an index that increases as the frequency, the number, or the amount of use of one or both of the purchase and the sale of the browsing right increases. For example, the value determination unit 36 increases the value as the index increases.

  FIG. 11 is a diagram showing another example (2) of the content of the price determination information 48B. The price determination information 48B, for example, for the user ID, the total amount of purchasing the browsing right, the total amount of selling the browsing right, the number of transactions (purchase or sale), the purchased content ID, the browsing permission of the content ID The information indicating the purchase amount of, the presence / absence of sale of the purchased browsing right, the sale amount of the browsing right, the purchase date, and the sale date is associated with each other. Note that the information that the own device does not hold is acquired from another device such as the content selling device 30 or the like.

For example, the value may be derived based on the following formula (3). For example, in the equation (3), “C” is a price, “K # 1” is a set positive coefficient, “K21” is an index indicating the total purchase amount, and “K22” is an index indicating the total sales amount. , “K23” is an index indicating the number of sales / number of purchases. For example, “K21” is set to increase as the total purchase amount increases, “K22” increases as the total sale amount increases, and “K23” increases as the number of sales / number of purchases increases.
C = K # 1 (K21 + K22 + K23) (3)

  As described above, the purchase amount to be paid to the user can be increased by setting the purchase amount to be high when purchasing the read permission from the user who is more fluidizing the read permission. Then, it is possible to give the user an opportunity to purchase the browsing right according to the paid purchase amount. As a result, it is possible to promote the circulation of the right to browse electronic content.

  Also, the price may be determined based on the date and time when the user who sold the browsing right purchased the browsing right most recently. For example, as the date and time of the latest purchase is farther from the current date and time, the price can be set higher, and the user can be prompted to purchase browsing rights by returning part or all of the price to the user.

  In the determination of the price, any item may be used from among the items associated with the content ID (described with reference to FIGS. 9 to 11) or the user ID. Further, whether to increase or decrease the index corresponding to the item may be arbitrarily determined. Also, the purchase amount to be paid to the user may be determined based on the determined value. For example, the purchase price may be set to be larger as the price is higher.

  Also, the value may be determined based on the processing result of the content selling device 30 and the publisher device 100. For example, when the content selling apparatus 30 purchases electronic content managed by the publisher device 100 collectively in a batch (for example, when purchasing 1000 viewing rights), the content selling apparatus 30 pays the content selling apparatus 30 The price may be set higher than before purchasing in bulk. In this case, the content purchase device 50 may set the purchase amount higher than before the content sale device 30 collectively purchased the electronic content.

  According to the embodiment described above, the content management system invalidates the purchase unit 54 that purchases the right to browse the electronic content from the user according to the user's request, and invalidates the browse right purchased by the purchase unit 54. The distribution of electronic content can be promoted by providing the unit 56 and the price request unit 58 for acquiring the price corresponding to the purchase from the content seller who has sold the browsing right purchased by the purchase unit 54 to the user. it can.
