Except that obtaining personal identification card, new intrant also need buy reader/computer or other acceptable arrangement for reading (as special computerized interface, audio or video reproducing device).To above-mentioned each an equipment unique sequence number of distribution and a specific coding numeral.In one embodiment, the read-only storage chip that is encapsulated in the equipment comprises this sequence number.In the following manner, promptly have only relevant devices could read the mode of the information that writes down on its cassette tape, all cassette tapes of subsidiary this type of arrangement for reading are encoded.This is to utilize the simple program that comprises in the permanent memory of this equipment to realize.In one embodiment, if it is digital different that the specific coding on the equipment and cassette tape are being searched, then this cassette tape will be on arrangement for reading display message " this equipment can not be read cassette tape ", and do not allow problematic specific arrangement for reading, further visit any information that comprises on this cassette tape.If the numeral coupling then allows further visit.When buying arrangement for reading, the salesman can stand by the cashier, and the sequence number of this equipment is input in the central database.Central database comprises the tabulation of the sequence number of all permission arrangement for reading, and corresponding specific coding numeral.The salesman will buy the person identifier card of arrangement for reading for the client, put in the suitable slot on the cashier station, and utilize the proper sequence number of the arrangement for reading buying, and the magnetic stripe on the tag card is encoded.After this, whenever the user need obtain additional cassette tape so that when utilizing his or her arrangement for reading to read, this user only needs to submit its person identifier card and the cassette tape of wanting correct coding to the salesman, and by this cassette tape is inserted in the cassette tape slot, tag card is inserted in the card slot, by the designated button on the cashier station, just can be that this user's arrangement for reading is readable then with new cassette tape correct coding.

Before allowing visit, need arrangement for reading coding and cassette tape codes match, the cassette tape that this means distribution can not become numerous arrangement for reading and can read easily.Numerous equipment are read will be needed special programmed process and grant special permission, promptly permit purpose.In one embodiment, by information being carried out purpose coding (purpose code), publisher can expand or limit the visit of the user with proper authorization or institute's definition purpose.For example, it is readable that publisher can be encoded to all users with certain a part of purpose of selected books, i.e. universal coding.For example, the purpose coding that uses this type on books or some government publication can promoted.Other information purposes can be encoded to limiting access, so that have only certain individual consumer to check this information, i.e. grouped data.This need reduce the possibility of unauthorized use message header.

In operation, the client carries its customer ID card, arrives the books viewing area so that buy 400.If the client opens an account before this, then this client need not to carry out said process, and directly arrives shopping zone 400, and the client will select certain and its books to select the books inventory card of coupling in this zone.Be printed on ISBN number of this books, a bar code and information, author, publisher and the version date relevant on the books inventory card with the customizing messages title.The client with selected books inventory cassette tape to the cashier 308A that stands.The cashier utilizes magnetic to read coding on the Customer ID, and the bar code 402 of scanning or manual input books inventory card.Then, the client suitably pays, and encoder client and message header coding transmission are arrived Hosts file server 304.The existing customer account number file of server 304 search to be mating this sign (being PIN and password), and according on the books inventory card or the bar code of manual input, generates the books listing file of downloading.Server 304 downloads to stack room 302 with this document, and latter's electronics generates the message header file that can download when needing.Shown in step 404, the user can arrive stack room 302 in any time after a while, tag card is inserted in the slot 340 in stack room 302, will be inserted in the stack room cassette tape slot 348, identify himself to utilize the personal identification number through the point of purchase cassette tape 374 of coding.This user utilizes keyboard 338 input passwords 406 simultaneously.When stack room CPU350 utilizes the listing file folder coupling personal identification number who downloads, stack room CPU350 is through buffer storage 360, begin and will from local storage 356, information requested download to media drive 354, the latter with this information copy to cassette tape 374.As the part of downloading process, data are carried out dynamic encryption, so that have only the arrangement for reading of mandate just can read these data.In the D part, dynamic encryption is described.After download, the user takes off cassette tape 374, then cassette tape 374 is inserted in his individual reader/computer, to visit the information that needs.This reader/computer is configured to read for a long time application program.This reading application software is stored on the cassette tape, and can be in this reader/computer or other be authorized the memory of arrangement for reading permanent storage, on the cassette tape, but read application software.

The user can select some part of selected information to make up and download.In one embodiment, the user can select at least one books and select at least a portion of each selected books.If selected a more than part, wherein each several part comprises until whole selected books, then can make up these parts and downloads in user's the cassette tape 374.For example, for specific college course, the student may need to download particular chapter from ten different books.After ten particular chapter selecting ten books and selected books, the combination selected information is used the protection level of determining to encrypt, and is downloaded in student's the cassette tape 374.Equally, the user can select each song to make up from music information, and selected song is downloaded in the single cassette tape 374 for resetting after a while.

2. hire out the some delivery system

If the user is not interested in the persistent copy that obtains particular work, and need the copy of certain period, as the copy in certain term, then this user may more wish the visit taxi point website rather than the point of purchase.Fig. 9 represents to hire out dot system.Except that below the difference pointed out, the point of purchase system of rental system and the above-mentioned explanation of this paper identical (as, comprise a Hosts file server).In many examples, the dot system website can and be hired out as point of purchase system website in single-site or stack room, and the payment dot system that is used to promote or business information website or its combination in any.As shown in Figure 9, hire out dot system and comprise the stack room user terminal hub 410A-B that is connected to terminal 412A-E, and customer service website 414.User terminal 412A-E allows the user that the stack room memory is carried out message header search and indexed search, and transmits other information between stack room 302 and it.Customer service website 414 associating customer service functions and cashier station.For example, at customer service website 414, credit client's debit card can be bought on credit, and if necessary, by atm module 416, can refuse the ATM operation.By printer 418, can be from the customer service station 414 type informations.

In rental system, use and hire out some storage medium 420.Except that medium 420 comprised automatic deleting mechanism, it was identical with point of purchase medium 374 to hire out some medium 420, and wherein deleting mechanism is deleted the information of downloading after preset time expires at interval automatically.Or rather, when downloading to medium 420 on from stack room 302 information, one " time stamp " also downloaded in stack room 302, and this time stamp equals the prepaid period that is used for hiring out the copy of this information of user.This time stamp is taked following form, i.e. form that is loaded into the value of certain memory location on the medium 420, and this value is corresponding to hiring out the period.In use, from the period of electronic representation, deduct time used.In case the user has consumed all time of licensing, this message header is destroyed the oneself, promptly from medium 420 deletions.Only need call a program stored, just can realize this operation, wherein program stored deletion and the relevant information in memory location that is worth memory time.For example, when the value of licensing the memory location of time when storage equals 0, will call program stored and delete and license the information of time for " 0 ".

Another kind of auto-deleted method is, each is hired out or stack room (library) cassette tape comprises independently rechargable power supplies of a real-time clock and.When encoding for use to cassette tape at first, activate real-time clock mechanism.When downloading the message header of hiring out, a date of expiry is registered in the index information of a title.Any time after the date of expiry of the arrival of the real-time clock on cassette tape appointment, the message header that denied access is relevant.If do not prolong the use of title, then after arriving some days of date of expiry, use cassette tape can be from the memory of cassette tape this message header of permanent delet.Utilize the method, if real-time clock can not move, then do not repair, this cassette tape will become unreadable.Repair the cassette tape of inefficacy, the user only need carry cassette tape and snap into together with its person identifier and reach nearest service centre, and in service centre or repair real-time clock, perhaps title is loaded into and substitutes in the cassette tape for information about.And with cassette tape not readable during the loss time return this user.For example, service centre can be positioned at the place of paying the some website near each.

Can be in the mode of operating system module, or be designed to " terminal is resident " (TSR) can independent executive program mode, create automatic delete program.Preferably adopt and the integrated module of operating system, this is that operating system can be moved because this structure can be guaranteed, removing module just can move automatically.

For any specific message header, if the user still needs more time, then this user turns back to the taxi point, " hires out " this information then again.As selection, can imagine that this user can upgrade taxi by the modulator-demodulator that is connected to reader.

As for the user procedures that is used for rental information, when a taxi point client enters taxi point website, the user will use effective atm card, bank card, credit card or other debit card, and directly arrive user terminal 412A-E.By using this Terminal Type, the user can carry out the message header search, and will order downloads to stack room 302.When the carrier strip order is finished instantly, this user will arrive stack room 302, will hire out medium, tag card, credit card, bank card or debit card and be inserted in the stack room 302, carry out transaction approval.If can not remove transaction, perhaps ATM system cisco unity malfunction, then client can arrive Customer Service Center, please waiter refuse ATM by hand and handle, if applicable.If the user does not have effective ATM credit or debit card, then this user will arrive Customer Service Center, pay so that charge to the credit side of stack room debit card to waiter.The client can arrive user terminal then, downloads and orders clauses and subclauses.

After removing trading approving, client will hire out medium 420 and be inserted in the stack room media drive 354, scan its person identifier card and input password.Information is carried out dynamic encryption, and 302 download to medium 420 from stack room, wherein this information has the time of licensing number of each message header or the electronics time stamp of date of expiry.After download, the user will use this medium on individual reader/computer, to visit the information on this medium.

The typical case that is used to hire out a website is library's (commercial, education or public visit) and books taxi shop.The information of user's download can be free, as the library, also can collect some with set price and go out rental, uses to the basis with every page and charges as hiring out shop or library.All specify a taxi point website to run in the mode of traditional libraries, wherein allow the member of library freely to use in certain finite time section, also can run in the mode of hiring out the shop, wherein charge to the user according to the life cycle that allows.

3. stack room subsystem

Shown in following detailed description, the stack room subsystem is connected to the Hosts file server with stack room.The central module of subsystem is stack room, and these stack room are the revisions in point of purchase stack room 302.This subsystem is member or commercial entity or company clerk collective use particular arrangement.In its authorized user in commerce or corporate entity, pay and the call back message title, and the copy number purpose ability of the appointment works that restriction can issue to other unauthorized users is provided.If certain in-house office worker has checked all permission copies of all message headers, then other users can not visit the same message header in the particular subsystem, until subsystem is uploaded or recalled to a of customizing messages or several parts of permission copies, perhaps bought till the additional copies.In one embodiment, information is carried out the purpose coding, thus the purpose of this information of restricting user access.For example, the central library of company can allow the special user, and as the research staff, selection information is as the pending application application.Stoping does not have suitable purpose or authorizes all non-research staff of coding to visit this information.

The limited use of the unrestricted copy of number can be leased by commercial entity, or uses the specific part of appointed information title, rather than buys the unlimited use of the restricted copy of number.In this kind situation, when commercial entity visits this subsystem from participating in work station, all can charge to the customizing messages title division of visit, and the access-hours charge to occurring.Utilization is in the restriction that participates in encoding on the interface between work station and the subsystem, during from the subsystem visit information, can the restraint of labour station carries out the ability of some operation.Restriction is operating as and relates to following data and duplicate operation with transfer of data, promptly relates to from the data of subsystem visit information title and duplicating and transfer of data.

Or rather, with reference to Figure 10, stack room subsystem 422 is a high-resolution color graphics adapter 424 that is connected to CPU426, with the instruction and the state of display subsystem 422.Subsystem 422 also comprise one can limited access system keyboard 428, be used to key in the selection of some appointed function of execution such as product showing.Subsystem 422 also has a media drive 430, is used for download message and a local storage 432, and the latter keeps the file of institute of commercial entity purchase order information for use.Provide additional storage 434, with all software programs of the function of retentive control and executive subsystem 422.Subsystem 422 also comprises power supply 436 and uninterrupted power supply 438, moves continuously when guaranteeing power failure.Provide printer 440 to print various report.

Stack room subsystem 422 has network interface 442, and the latter is connected to stack room 302 and Hosts file server 304 with subsystem 422.Also network interface 442 is connected to company or commercial entity's network system 444.Utilize this kind structure, corporate entity can or download its distinctive company Proprietary Information by 422 transmission of stack room subsystem.

Media port expansion interface 446 utilizes the media drive of right quantity, and the visit to the required company terminal of company's site is provided.By proprietary driver card, media drive 430 is connected to terminal or website.Company management person can use the dynamic encryption and the dynamic download function of stack room subsystem 422, so that incorporate and hold the Proprietary Information of company into.Can use ciphering process that the Proprietary Information of company is transferred to stack room subsystem 422, download to the authorized person of destination interface and correct identification then selectively.Stack room subsystem 422 is not only a company library customization, that have copyright and Proprietary Information, also is company's document security equipment, and it encrypts and distribute the secret Proprietary Information of company's document and company in company's network.Be connected to subsystem, and allow the individual components of the part that the network interface of visit enciphered message connects as each being participated in work station, memory member for example, some operation that restriction can be carried out from work station, thus work station can be visited enciphered message from subsystem.Above-mentioned restriction limits or stops and relates to that data are duplicated or the operation of transfer of data.

4. distribution delivery system

Marketing network is used for the payment dot system of promotional information and business information.It is promoted and business information with electronic format distribution, user or check digitized distribution and business information at website, perhaps with this download of information to its personalized medium in order to checking after a while.The user asks visit to be promoted and business information, and wherein this information comprises advertisement available discount, commerce, special sales promotion, software demonstration and the catalogue of dynamically checking in the electronics mode.By handle promoting and business information, utilize Email to order from individual reader/computer then, perhaps directly promote stack room and order, user even can carry out electronic business transaction from interactive mode.The structure of promoting stack room is identical with the stack room structure of point of purchase system.

Figure 11 represents according to marketing network of the present invention in the block diagram mode.As in other point of sales systems, stack room 302 are connected to Hosts file server 304.Marketing network also comprises the distribution parts 448A-D that many electronics show and promote the sale of products.Directly parts 448A is connected to central transaction database 104 and central information storehouse 100, and parts 448B-D is connected to Hosts file server 304.Parts 448A receives information from retailer terminal 450A-D and Hosts file server 304 reception information by retailer terminal 450E-G.Or rather, Hosts file server 304 is by retailer terminal (MT) 450E-G, from local commercial, the whole nation or the renewal that receives advertisement there and provide especially of regional advertiser and sponsor of company.Simultaneously Hosts file server 304 is networked to central transaction database, the latter provides report to publisher, advertiser, record keeping, Auditing firm, commodity production merchant and other staff again.

The distribution stack room allow to promote the taxi medium (referring to the argumentation in the B part, system architecture is to illustrate this type of download) that selectively downloads to the user with business information, check and purchase at the convenient time for user individual.As above with reference to hire out the explanation of some delivery system like that, when expiring at interval at the fixed time, the distribution of download and business information are destroyed the oneself (promptly automatic the deletion).Promote the self-service sale function that stack room also provide a kind of user interactions.The user can pass through network electronic order products or information.Some promotes function: reward voucher, virtual shopping, catalogue sales, demonstration, the subscription that needs ordered, the service of electronic application credit card, trading card or other kinds.Also can issue some public sphere information to community under with the situation of promotional information as free or low-cost service, as community activity, ticket thing sell, mechanism's activity even bulletin.

Distribution and business information stream are very similar with the information flow in the delivery system of point of sale.Yet information source is local commercial, the whole nation or regional advertiser, via the suitable sponsor of advertisement agency and other entities, rather than the owner of publisher or copyright information.

5. information trace technology

In one embodiment, for each time exchange or the download of information, with following the tracks of the clauses and subclauses transmission or storing suitable transaction data base into, in central transaction database 104, so that recorded information moving or transmitting from the primary importance to the second place.By checking above-mentioned tracking clauses and subclauses, what the information owner can monitor message moves, and takes appropriate measures.For example, whenever with information copy when the stack room 302, from stack room 302 during deletion information, or from stack room 302 during copy information, all clauses and subclauses followed the tracks of in one of record in transaction data base 104.Follow the tracks of clauses and subclauses according to these, the information owner can collect the charges to recipient or sender according to the standard of his definition.Charge can include but not limited to based on following various factors, the economic worth of information, the use of information or purpose, number of users, and the availability of other information sources.Follow the tracks of clauses and subclauses and can also comprise additional data, thereby the owner of information can determine that who have transmitted this information, the amount of information of transmission, transmission type (for example, hiring out the time period of appointment), and delivery time.In one embodiment, write down the tracking clauses and subclauses of all transmission, comprise stack room 302 to cassette tape 374 and central information storehouse 100 to stack room 302 transmission clauses and subclauses.By using these clauses and subclauses, the owner of information can also determine the information type that transmitted to transmit number of times, and information receiver's identity.For example, can use this information to determine whether the targeted customer has received some promotional material, perhaps determine reflection different information price strategies.

D. encrypt

In the time of on downloading data to user's storage medium, above-mentioned point of sale delivery system can carry out dynamic encryption to these data.Dynamic encryption refers to that stack room work with storage medium, with the process that institute's data download is carried out proprietary encryption.In one embodiment, according to a succession of factor or variable, use the encryption of different stage.These variablees include but not limited to, the economic life of information, market value, general availability, alternative costs, time sensitivity and potential user's number.For example, current list of television programmes has the encryption than low level (being lower complexity), and its reason is that market value is lower, alternative costs are lower, and from the general availability of many information sources.On the contrary, the law of a multireel is discussed the encryption level with higher (promptly complicated), and this is because the limited availability of this information, alternative costs and long economic life.According to above-mentioned factor, the information source of information (being publisher) can determine, is transferred to the suitable encryption level of each several part information of user's cassette tape 374 at first from center information bank 100.The information encryption rank of a certain position (as storehouse 100) can be higher or lower than the encryption level of another location (as cassette tape 374).Or rather, download at every turn or during transmission information, can independently change or definite encryption level.For example, the encryption level in central information storehouse 100, can with the encryption level different (promptly being higher or lower than the encryption level of books) of the books of the cassette tape 374 that downloads to the user.

Except that dynamic encryption, can carry out other encryptions by mode shown in Figure 12.Figure 12 represents three rank ciphering process.For example, can data be encrypted with before message transmission is to the network.This is easy to stop the information of unauthorized user access transport to the network.Except that before transmission, encrypting, can also before putting into stack room, encrypt data.Other owners of publisher or information can have permissions to this other encryption of level, so that the owner of information provides the enough data protections that make its satisfaction for this reason.

In case storage in stack room, just can be used the dynamic encryption technology when these data are downloaded to storage medium.Storage medium (Fig. 7) comprises that is used to a proprietary environment that makes up, reads, checks and handle.This medium also has the commercial operation system that is used for the process information file.The registration of message file catalogue constitutes a part of specific application, and the operating system application program comprises a file pointer.

When downloading data to user's storage medium, the dynamic encryption process is used the permanent sequence number of storing on this storage medium, this user's personal identification number, idiographic Code Number and password with certain form, with the further data encryption to storing in the stack room.Personalized variable and coding and various personnalit message file variable are made up, download to the individuation data structure of the data on the user personalization medium with formation.Therefore, above-mentioned message file is the personalization files that is fit to this medium, software version, message file itself and its dependent variable.

By making all information of downloading via point of sales system, become the readable and addressable information of selected user reader/calculating plane No., dynamic encryption helps to reduce the possibility of unauthorized use Proprietary Information or other information.Particularly, can be from the data storage medium of certain reader/computer access, can not use another reader/computer access, unless, presetted this type of visit by identical customer identification number and password is provided for other reader/computers.

For example, operable known algorithm comprises Z8068 data encryption processor (DCP) in above-mentioned three ranks are encrypted.This DCP comprises the cryptographic algorithm of using State Standard Bureau (NBS) is carried out encryption and decryption to data structure.Can use it in various environment, above-mentioned environment comprises the peripheral task processor in nonshared control unit, communication concentrator, terminal and the general processor.By the feedback that accesses to your password, code book or cypher block chaining operational mode, DCP provides high-throughput.The separate port, non-encrypted data and the enciphered data that are used for the key input have strengthened fail safe.Host computer system is used in the order of master port input or by the assist control line, communicates by letter with DCP.In case install, data can pass through DCP at a high speed, this be owing to can the executed in parallel input, output and cryptographic operation.

In another embodiment, can in specialized hardware and/or software function, carry out encryption and decryption.For example, each reader and cassette tape 374 can comprise a dedicated encrypted integrated circuit (IC) and a special-purpose deciphering IC, so that the arrival of the transfer rate of information is the highest.By adding additional function and, can changing the encryption and decryption rank by enabling or forbid additional level.

For dynamic encryption, a kind of method in operable numerous dynamic encrypting method is described hereinafter.Particularly, as shown in table 1, each letter and number symbol that often uses is assigned corresponding number.
