Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a work management method for rationally performing processing related to management and use of a work provided in various forms.
[0002]
[Prior art]
The protection and management of copyrighted works are registered and monitored by a copyright protection organization, etc., and various technologies are used to prevent unauthorized use, such as copy-protection technology using digital watermark and decryption technology using user ID. are doing.
[0003]
[Problems to be solved by the invention]
The distribution method of copyrighted works has been diversified and the speed of change has been intense, and illegal use has been increasing due to the inability to thoroughly protect copyrighted works. In such a situation, there is no simple protection technology having commonality, and the distribution is impaired and the manager is not efficient. In addition, the method of use is also an alternative of whether it can be used or is impossible, and the degree of freedom of the form of use is small and extremely limited.
[0004] Specifically, it is generally desired to grasp the outline by trial listening, trial reading, trial use, etc., but any protection technology is hardly available, so that the sales promotion effect of the copyrighted work itself is small and it is difficult to use. . In addition, since the authentication data does not change and remains constant, the operation history is hardly grasped.
[0005] Further, after being distributed to the market, the distribution actual situation and the form of use can hardly be grasped, so that the illegal use is not stopped without fail and the author suffers a great disadvantage.
[0006] The present invention provides a means for solving the above-mentioned problems, and is a simple protection technique that satisfies both convenience and satisfaction for the author, the work manager, and the user. The purpose is.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention can specify an individual work by integrally attaching a management code unique to the work to the work, and can change the management code. By doing so, the use history of the work can be recorded and the history from the past to the present can be grasped, so that appropriate management and operation of the work can be rationally performed.
[0008] The step of attaching a management code to a work makes it easy to recognize and distinguish individual works and to easily grasp the distribution status of the work. Further, by controlling the degree of disclosure of the work in accordance with the contents of the change of the management code, it is possible to provide various use forms of the work.
Since the management code is composed of a code unique to the work and a part where the history is recorded, it is possible to easily grasp the actual use of each work.
[0010] Even if a work is distributed in an incomplete state, data for making the work complete is already integrated, so that it can be easily restored as a complete work without additional data. It becomes possible.
[0011] The work is protected by reducing the use value of the work which escaped the management because the imperfection increased according to the number of uses, the use period, or the elapsed time of the work.
[0012] By converting the copyrighted work and its management information as electronic data, the efficiency of the copyrighted work management and high-speed processing can be achieved, and the update of the management contents can be arbitrarily controlled, so that various uses of the copyrighted work by users can be achieved. It is possible to respond immediately to the form, and the user's convenience and protection of the copyrighted work can be thoroughly ensured.
[0013] The usage fee is automatically calculated and charged according to the management code change history, thereby enabling a reasonable collection of money.
[0014] The registration and use of a work can be easily promoted by a method of managing a work having means for grasping the actual use of the work and means for varying the usage fee according to the degree of use of the work. .
Anyone can easily receive the distribution of a copyrighted work by means of a device that makes the means and procedure for making the copyrighted work data usable electro-mechanically process.
The individual data and the code strings or groups of a plurality of management sensors or management codes integrally attached to the copyrighted work cooperate with each other, thereby verifying the respective data and making a difference so that improper handling is possible. Detecting the presence of the item enables more reliable management of the copyrighted work.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a typical configuration diagram showing a processing procedure of a work management method. The author 1 creates a work 11. The creator 1 makes a management registration request 4 for the literary work 11 to the literary work manager 2 and entrusts the management of the literary work. The manager 2 performs data processing for the work management code assignment 5 on the requested work 11 and attaches the management code 6 to the work 11 to make the work 11 a work 12. The administrator 2 publishes the work 12 widely to the public and encourages its use. The user 3 of the literary work 12 can use the literary work 12 according to the usage form by applying for the license 7 to the manager 2. Then, the used contents are stored in the management code 9 as the use information record 8 and become the copyrighted work 13. As described above, the management code 9 is changed or updated every time it is used, and its history can be left. The literary work 12 becomes a management original, and the management code 6 and the management code 9 are compared and collated 10 so that the progress of use can be grasped. These pieces of progress information are sequentially recorded and stored in the copyright management database 16 of the manager 2.
Here, a work is a book, a magazine, a book, a book, a musical score, an article, a document, a report, a map, a written work, a literary work, a document such as an academic book, a movie, a movie, an animation, a CG, Pictures, portraits, paintings, artworks, Web contents and other images and visual media, audio, music, music, poetry and other auditory media, architectural designs, marks, designs, etc., recipes, drawings, blueprints, plans Software, such as books, proposals, games, and other programs, trade names, titles, trademarks, copyrights, and other creations in general, and their duplicates, electronic data or digitized contents, and storage media for recording these .
Further, in some cases, it is not rational to provide the work to the user, so a copy of the work is distributed or supplied. These media include distribution of electronic data by using communication / broadcasting networks such as various network networks, telephone lines and wireless lines, supply as digital recording media such as CD / MD / DVD, and other electronic papers. , Audio / video tape, film, record, semiconductor memory, etc. can be widely used.
The management code is a unique management number assigned to each work in order to distinguish each work. In addition, it is an aggregate of data including copyright information and attributes of the copyrighted work, available service information, and the like.
Referring to FIG. 1, the work manager 2 attaches the management code 6 to the work 11. The author 1 or the copyright holder requests the work manager 2 to register and manage the work 11, and the manager 2 performs management code assignment 5 to integrally manage the work 12. A code 6 is attached. As a result, the management of individual works 12 becomes possible.
The publication of the literary work 12 is carried out by selling it at a store or distributing it as a data file on the Internet. At this time, the work 13 that can be recognized by the user is the work 12 itself or a copy thereof. If it is a duplicate, that fact is recorded in the management code 9. When the copyrighted work 12 is directly disclosed, only the management code 6 is recorded and stored in the copyrighted work management database 16 managed by the manager 2.
By the way, the PR for sales promotion is based on a known means which has been conventionally performed. However, it is possible to improve the effect by using the control of completeness and accuracy which is a feature of the present invention. I can do it. Specifically, a deeper recognition of the literary work 13 becomes possible, for example, a part that is likely to be interesting can be appropriately selected and viewed, or a specific function can be experienced. However, it is needless to say that the user 3 can use the application within the range of the recognition and the function being serviced in a normal state without necessarily requiring the consent of the administrator 2 to the license 7. No.
In some situations, the use form incorporated in the management code 9 includes an option that can be used immediately only by agreeing to a billing table indicated according to the use range. At this time, a simple method such as adding to the usage fee of a communication company or a provider can be applied to the settlement of billing.
In order to attach the management code, various media recorded as the management code, for example, an object or substance capable of recording electronic data, optical data, and biochemical data, or a tangible object In this method, an electromagnetic / optical recording medium such as a semiconductor memory chip on which management data is recorded is directly embedded in a work so as to be integrated with the work. At this time, if only the chip is removed or removed, the value of the copyrighted work itself is lost.
An intangible object is converted into electronic data capable of expressing it. For those originally supplied via electronic data, the management code is recorded integrally with the copyrighted work data as electronic data. In the same manner as described above, if these are falsified or falsified, the utility value of the work is lost.
To change the management code, for example, access is made to the electronic data in the management code storage area 21 attached to the work 20 in FIG. This is performed by processing such as data change and addition, other update, conversion, correction, and correction by the exchange means. At this time, encryption of data, regulation of a change procedure, setting of a password, and the like are performed so that a person other than an administrator cannot easily make a change.
The management codes 6 and 9 are integrally attached to the works 12 and 13 in FIG. 1. The management code is a unique code given to each work and its copy, and includes characters and characters. It is the only one composed of a combination of symbols or numbers.
These are composed of an identification code 31 and a history code 32, as in the configuration example of the management code shown in FIG. Each code may be defined by referring to a separately set data table or database depending on its symbol, value, or its position.
The part of the identification code 31 is the registration number of the copyrighted work manager and is invariable. Along with this, an outline of the work, such as the name of the work, the author, the copyright owner, the date and time of the work, a list of related collaborators, the selling price, the usage fee, the usage period, the information amount (data amount / bit number) / Number of characters, number of images, etc.), serial number, management code, renewal deadline, etc., and other attributes, etc., which are used to assist the user in making decisions for service reception. It becomes. As described above, since the identification code portion is a data portion that does not always change even when used, it is inherited as it is even when copied. Of course, in this case, the copied fact is recorded in the history code.
The portion of the history code 32 is a portion that always changes every time according to the use result and the use mode. For example, it may include the current owner / administrator, date and time of acquisition, password, date and time of use and use, period, location information, purpose of use, number of uses, number of users, playback media, restoration device name, etc. It is also possible to add other arbitrary data. These detailed data are selected as necessary and recorded in the usage history. By the way, what is left in the use history can be uniquely determined by the copyrighted work manager, but the user can also handle the recordable area so that the recordable area can be set arbitrarily. In the case where data cannot be recorded in the history code portion attached to the work or the recording is requested by a user's request, the work is recorded and stored in the work management database of the work manager.
Note that, in the case of free software or a copyrighted work whose use is freely permitted, the history data may be omitted or not changed or updated. These codes are compressed / encrypted as necessary. Further, it is easily understood that the form and the configuration of the management code 30 in FIG. 3 are not limited to this example, and any form can be applied.
Here, the use of a copyrighted work means browsing, disclosure, distribution, viewing, appreciation, appreciation, use, trial, sale, resale, lending, licensing, authentication, transfer, settlement, duplication, modification, correction, repair, It refers to reproduction, editing, publishing, broadcasting, and other uses, and the use and processing of these data.
A work which is generally published and recognized is an incomplete work main content 40 in which a part of the work shown in FIG. Since the distributed work includes data groups A to D that can compensate for the missing parts as the work sub-contents 41, these can be restored as a complete work by combining them. Note that the management code 42 and / or the decoder 43 as the restoring means may be attached to a distributed product or provided from time to time by a copyright manager.
The work main content 40 is partially missing data a to d and cannot completely recognize the work. On the other hand, the copyrighted work sub-contents 41 are also data strings and groups A to D that have no meaning at all. Restoring these to a complete work can be easily realized by writing predetermined data of the work sub-contents 41 in which data corresponding to the missing part is recorded in the missing part.
The restoring means and procedure are as follows. It is the management code 43 that controls the incompleteness. This is data that is set by the copyright manager and cannot be changed by the user in general. Then, since the missing data portion is associated with the location of the data in which the missing data is stored by the decoder 43 in accordance with this data, the missing portions can be connected accurately. More specifically, since the missing part a of the work main content 40 can be recognized as being present in A of the work sub-content 41 according to the result of the decoder 43 set by the management code 42, this data A is transferred to a. By doing so, the missing part is repaired, and by repeating this sequentially, it is restored as a complete work.
In the management code 42, an area for performing processing and management such as a function of presenting a usable service, a usage fee, and a usage method is set, so that a license is granted to the copyright manager for each user request. It is possible to receive immediate response and various services without requesting. Also, for higher protection such as preventing unauthorized acquisition in the distribution process, pseudo data is added or deleted to the management code 42, and the data is completely restored when the data is first reproduced. Management code 42.
The decoder 43 is software for supporting appropriate restoration in cooperation with a restoration system, a reproducing apparatus, and the like. Depending on the restoration environment, the copyright manager may be requested to update the data for optimization, but the update can be performed by an easy means such as downloading from a network or obtaining a storage medium. In a simple work, the management code 42 may have this function, and may be omitted. The function of the decoder 43 also manages the transfer, conversion, synchronization control, level adjustment, and the like of data from the work sub-contents 41 to the work main content 40, but other software or hardware is used to support the functions. May be interposed, but the description here is omitted.
An incomplete copyrighted work is one which has been subjected to measures such as insertion of useless data other than the loss of content, superposition of signals that are likely to cause malfunction, skipping, jumping, or repeating the same. The area may be partial or entire, or the position, the location, the number, etc. may be arbitrarily set.
The history code 32 shown in FIG. 3 further comprises a usage history 51 and an additional code 52 as shown in FIG. Here, each time the usage history 51 is used, a predetermined position is updated in accordance with the usage mode. However, the additional code 52 is used when the number or character constituting the code is used without using it. The number of recognizable numbers such as characters and symbols, the size and order of arrangement, the change of attributes, and the like are unilaterally caused. The decoder 43 detects this and controls the integrity of the restoration according to the degree.
The recording position of the additional code 52 does not necessarily have to be integrated or at the same position, but may be a position that is susceptible to changes over time or a place that is easy to take means. Further, the additional code 52 is added according to the use form of the work, and is not always necessary. For example, the code is automatically activated or generated when unauthorized use or management data is recognized as being illegal. The additional code 52 can be reset or partially restored when the user is under the jurisdiction of the administrator or when the user performs appropriate authentication, update, or billing. As a result, a work which can be used without any problem on the basis of a certain standard that has been permitted at first can be protected as soon as the work is used or it becomes gradually unrecognizable over time.
Imperfections include deletion of part or all of data, denial of access, deterioration of contrast, resolution, color, etc., increase of noise, noise, mosaic, interference, blank space, specific frequency, band, A state in which the original copyrighted work cannot be accurately reproduced or recognized, such as a lack of sound and color, an increase in abnormalities such as functions, modulation, synchronization, synthesis, duplication, encryption, and order.
The additional code 52 is changed because the data obtained from the processing of the identification code 31 and the use history 51 according to the data transfer from the copyright manager and the degree of use of the user, and the function medium that changes over time are recorded. This is due to the change in the data. Here, the deterioration of the functional medium is caused by electromagnetic fields, light (ultraviolet rays, infrared rays, laser etc), heat, pressure, humidity, vibration, gas, other physical and chemical stresses, etc. Decreasing or recorded data is gradually lost or lost.
The electronic data referred to here is an electric signal obtained by converting a work or its management information into a digital signal or an analog signal, and reconstructs the original work or its management information based on the signal. Possible data. These can be instantly and quickly transmitted over a communication network or easily recorded and stored in an electromagnetic optical storage medium, and various distribution means can be selected. Also, the extremely high information density makes it ideal for managing vast amounts of copyrighted work.
In particular, by monitoring the management data attached to a copyrighted work on a network, the distribution state of the work can be grasped, and it is possible to easily find out the unauthorized use and track the results of the use. In addition, since the mutual data exchange between the administrator and the user is easy, a more advanced service can be realized, and as a result, the profit of the author can be obtained.
The charging procedure will be described with reference to the configuration diagram shown in FIG. The difference obtained by the comparison and collation 10 between the management code 6 and the management code 9 corresponds to the result of use. Then, a comparison is made with a price database which is determined separately according to the usage form and service contents, and a substantial usage fee is calculated by removing a portion which is not charged or a portion which has been settled.
The result is notified to the user 3, and by agreeing to the contents, payment 14 of the usage fee is executed to the administrator 2. Next, the royalty is paid to the creator 1 according to the regulation from the manager 2, and is settled. The usage status and the billing and settlement information of the work thus registered are sequentially recorded and stored in the work management database 16. It should be noted that the charging period and the cycle settlement method may be in accordance with known means such as cash and transfer, but it is also reasonable to include electronic money, credits, and usage fees of a communication company or a connection company for settlement.
By assigning a management code peculiar to a work to search or detect the work code, the use status of the work distributed on the computer network can be easily grasped. In addition, it is relatively easy to grasp the distribution status of a storage medium in which a copyrighted work is recorded as electronic data, and since these are reproduced and transmitted, the management code is more exposed, enabling more reliable verification and grasp. Become.
Using these data, the usage fee is changed according to the distribution amount. More specifically, if there are many users, raise the fee, and if there are few users, lower the fee. If the amount of circulation of the copyrighted work is limited, the price will be raised due to scarcity. For those who have little use, the usage fee is greatly reduced. These are determined by processing the data of the copyrighted work management database 16.
In addition, various factors for price setting are taken into account, and various fee systems can be easily realized. For example, free for a certain period or service of a special additional function can be executed immediately and totally.
The copyrighted work management device has a reading and reproducing function for restoring copyrighted data, and includes a function capable of reading, writing, recording, and communicating a management code to automatically perform complicated copyrighted work management. Run
Specifically, a code decoding function, a demodulation function, a data restoration function, a decoder function, an encryption function, a communication function, a browsing function, a synthesizing function, a converting function, a recording function, a reproducing function, a transmitting function and the like are processed. Includes storage media storing systems and programs to be managed.
FIG. 6 shows an example in which a management code chip 61 is arranged in a work 60. The management code chip 61 is also a management sensor. As described above, in the tangible object, the management code chip 61 is directly embedded or inseparably arranged so as to be integrated with the work. On the other hand, in the case of an intangible object, a management code 62 or the like is attached to data for restoring a copyrighted work.
A plurality of management code chips 61 are arranged in the work 60. Each of them has a unique code setting so that it can be clearly distinguished, so that the positional relationship between them and the detected data are compared and collated with each other to verify whether there is any abnormal change. In the management code 62, it is verified whether there is a change or disappearance of a data array or a character.
The management code chip 61 is interconnected by various physical and biochemical sensors, and changes in the position between chips, changes in the environment, stoppage of functions, loss and fluctuation of stored data, and the like. When the cooperation is interrupted or the like, it is determined that there has been an improper or abnormal handling, and a warning is issued from one of the chips. The management code chip 61 can be more reliably protected by being combined with a wireless tag having a communication function or an electromagnetic field or an optical recording medium that can be arranged over the entire work.
The management code 62 is an example in which specific characters X, Y, and Z are sequentially arranged at intervals of 2, 4, and 8. By verifying whether these relationships are maintained, it is possible to confirm whether the copyrighted work data or other data has been manipulated improperly. By providing a plurality of such codes in the copyrighted work data, a more complete abnormality can be detected. The configuration and arrangement of such a code can be arbitrarily designed without being limited to this example, and higher-level protection and verification can be performed by encryption.
If there is any abnormality, the contents are reported to the user and the copyrighted work manager, and the management code is changed or deleted. To be reduced to These restorations require re-issuance of the management code from the copyright manager. At this time, more reasonable work management can be realized by exchanging data by computer network or wireless communication.
The representative embodiments of the method for registering works and managing them according to the present invention have been described with reference to the drawings. However, it goes without saying that the present invention is not limited by the description of such embodiments. Further, it is expected that various changes, modifications, improvements, diversions, and the like can be made based on the knowledge of those skilled in the art without departing from the spirit of the present invention other than the description of the above specific examples. Should.
[0059]
【The invention's effect】
The present invention has the following effects by being implemented as described above.
Even after the distribution of a copyrighted work, the actual use of the copyrighted work can be reliably grasped and managed, thereby preventing unauthorized use and protecting the rights of the author. Further, since the copyrighted work is converted into electronic data, a handling and maintenance system can be simply realized, so that computerization and utilization of a network are facilitated, and rational management and operation can be achieved. Furthermore, since various forms of use are made possible, it is possible to further increase the use value of the work.
