With reference to accompanying drawing, describe the preferred embodiments of the present invention in detail.
The present invention can be divided into the situation that the user buys device and restriction functions of use roughly, and usage license source is hired out or to the situation of user's rent device.Following description is primarily aimed at last situation, and back one situation is explained subsequently.
At first, schematically explain system according to use electronic installation of the present invention.
Fig. 1 illustrates the example that has comprised according to the system of electronic installation of the present invention, carries out the method that is used to control this apparatus function in the system.Device side is as user side in this system, off-line or to be connected to the key distribution side online be manufacturer's side.
Particularly, when conveyer 10, device ID, promptly conduct is to installing 10 distinctive information of discerning, such as for device 10 suitable codes, be written in the internal storage of device 10, the existence/shortage with the use restriction of each function writes wherein as the function limit markers simultaneously.
Notice, in the present embodiment, be provided with possible test and use fate that as explanation subsequently, so user 10 is only from buying day corresponding to the function that can freely use restriction to use in the time of possible test usage quantity.
Bought restricted functions of use device and possible test use fate go over (sensation) thirsts for afterwards using should (these) function the user, be somebody's turn to do (these) function to device manufacturer 3 or to buying as key distribution source 5 applications of relative assembly manufacturer company.
Particularly, utilize off-line process 7, issue the restriction cancellation key, be used for the application that this (these) function buy of response from user 1 from key distribution source 5 to user 1.The user imports the restriction cancellation key auto levelizer 10 of such issue.
Just in case the device 10 in key distribution source 5 and server 90 are connected to each other by the wide area network 8 such as Internet, generate by off-line process 9 to server 90 and to be used to issue the request of key of lifting restrictions from installing 10, and the restriction cancellation key from server 90 to device 10 issues.
When the restriction cancellation key was input to device 10 or is received by device 10, the CPU of device 10 can rewrite the limitation function mark, as mentioned above, in the internal storage of writing station 10, thus user 1 can use purchase subsequently should (these) function.
Fig. 2 shows the example of the device 10 of digital audio device formation.
This device 10 comprises CPU11, and the bus 12 that is connected to device 10 has ROM13, RAM14, nonvolatile memory 15 and clock circuit 16.This ROM has stored into program, comprises the various programs of being carried out by CPU, as the back explanation, or such as the fixing data of installing data presented on ID or the screen.RAM is as the workspace of CPU11.Nonvolatile memory is the recordable memory such as flash memory.
Device ID by as stipulated the code of device 10 types just discussed and formed installing 10 suitable continuous numbers.
At device during 10 shipment, in nonvolatile memory 15, write and installed 10 existence and disappearance, and possible fate is used in test about the use restriction of various functions.
The function executing unit is that A/D converter 31, D/A converter 32, interface 33,34, scrambler 35, demoder 36 and hard drive (HDD) 18 also are connected to bus 12.A/D converter 31 will be converted to from the input simulating signal Ain of outside audio digital signals with output result signal to bus 12.The digital audio signal that D/A converter obtains on bus 12 after decompress(ion) and decoding is converted to exports analoging sound signal Aout, then exports it to outside.Interface 33 is caught the input digit voice signal Din of compression and coding to bus 12 from the outside, and the compression that obtains on interface 34 output buss 12 and the input digit voice signal of coding, as output digital audio signal Dout to the outside.The digital audio signal that obtains on scrambler 35 compressions and the coding bus 12, and the compression that obtains on demoder 36 decompress(ion)s and the decoding bus 12 and the digital audio signal of coding.HDD has hard disk 19.
That is to say, this device 10 has rough acoustic processing function, comprise that (1) will be converted to digital audio signal from the input analoging sound signal Ain of outside by A/D converter 31, compress and encode by 35 pairs of digital audio signals of scrambler, by interface 34 will compress and encoded signals export to outside as output digital audio signal Dout, or on hard disk 19 function of recording compressed and encoded signals.The acoustic processing function also comprise (2) catch by interface 33 from the input digit voice signal Din of the compression of outside and coding with by HDD18 with this signal record to hard disk 19, or be analoging sound signal Aout by demoder 36 expansion and decoding input digit voice signal and by D/A converter 32 with this conversion of signals, then Aout is exported to outside function.The acoustic processing function comprises that also (3) duplicate the digital audio signal that is recorded in hard disk 19 of compression and coding to export this reproducing signals by interface 34 as output digital audio signal Dout from hard disk 19 by HDD18, or by demoder 36 decompress(ion)s and this signal and consequential signal is converted to output analoging sound signal Aout by D/A converter 32 of decoding, then Aout exports outside function to.
Scrambler 35 and demoder 36 also have by such as MP3 (MPEG-1 audio layer-3) or ATRAC (registered trademark: coded system compressed/encoded Adaptive Transform Coding-3) and the function of decompressed/decoded voice signal.In the present embodiment, user restriction is forced on by ATRAC3 compressed/encoded and decompressed/decoded voice signal function and voice signal is recorded on the function of hard disk 19.
In the present embodiment, aforementioned in order to realize at line process, the network connection unit 27 that is used to be connected to such as the wide area network of internet is provided, and be used for receiving from the infrared light receiving element 29 of the key information of mobile telephone terminal transmission by infrared ray, wherein, key information is such as the restriction cancellation key, and mobile telephone terminal has the infrared communication function, as the back explanation.
As shown in Figure 3, whether each function setting that is labeled as device 10 of limitation function is to using the specific function dielectric imposed limits.In the present embodiment, be not imposed to the use restriction of function A, B, C, D, H and I among the function A to I, therefore these marks that do not have its limitation function of function of the restriction used be set to " 0 ".On the other hand, will use restriction to be imposed to function E, F, G, therefore the mark to these its limitation functions of function is set to " 1 ".
Be increased to limitation function mark be that possible fate is used in test, and result data is as table write non-volatile memory 15 is set.Use the function E of restriction to use possible fate to be set to for example 30 days for each to its test of G unanimity.
Use the function of restriction for these, CPU11 supervises the execution of each function by this way: if even in question function use once during one day 24 hours, the actual use number that this day counts to function reaches, conversely, if this function is not used during all one day 24 hours at all, this day do not counted the actual use number into function.Use limited function for each, the test that CPU will count like this uses fate as the admin table write non-volatile memory 15 shown in Fig. 3 B and the 3C.
Fig. 4 shows the example of the function executing control and treatment routine of being carried out by CPU11 in operating means 10 processes.
In the function executing of the present embodiment control subroutine, when each CPU11 will carry out given function, it read the mark of the limitation function relevant with function in step S51.In next step S52, whether CPU uses restriction to force on function from the content inspection of the mark of limitation function.If do not use restriction to force on function, CPU enters next step S53 to carry out function.
Just in case use restriction to force on the function that will be performed, CPU enters step S54 from step S52 and whether is less than the fate that may test use with the actual use fate up to the previous day of checking function.If the actual use fate to the previous day of function is less than the fate that may test use, CPU enters step S55 to check this function whether in this sky (same day) executed so.
If in question function was not performed the same day, CPU adds 1 from the actual use fate that step S55 enters step S56 and function.CPU enters step S53 to carry out this function.If function was performed on the same day, the actual use fate addition of function, CPU directly enters step S53 to carry out this function from step S55 so.
Because the counting of the actual use fate of function is controlled by this way, the test that will arrive the previous day uses actual fate and test on the same day to use actual number to write in the admin table as shown in Fig. 3 C.
The actual test that authenticates to the previous day among the step S54 uses fate to reach the possible fate of test use, and CPU enters step S57 to show the such effect of demonstration on 24: because the possible fate of test use arrives, function can not be carried out.Then CPU enters step S58, will carry out the hardware circuit of this function here and is not carry out stop (operation stop condition) of this function such as the software setting of being responsible for this function of drive software.
Obtaining of off-line issue and restriction cancellation key now is described.At first, this by mail or fax issue and obtain with reference to Fig. 5 and 6 explanations.
The method that is used for off-line procedure as shown in Figure 1, the user carries out the purchase of function to key distribution source 5 by mail or facsimile application, as shown in Figure 5.For this reason, when shipment, the device manufacturer of conveyer will be used to buy postcard 61, the mail 62 of function and seal 63 etc. with device 10 bindings.
The user on postcard 61 or mail 62 input media ID, he expects the effect of the convention of function, payment information and the user's license contract bought, and give issue cipher key source 5 with the postcard 61 or 63 mailing of sealing that wherein contain appended mail 62, perhaps mail 62 is sent to this key distribution source 5 by fax.Device ID also can be by the device manufacturer from another device of device input.
User's license contract forces user 1 to transmit by buying the restriction cancellation key of device acquisition to the third party by the method beyond the method for contract agreement, perhaps must not distort the above data that table or admin table are set.
Receive from user 1 be used for application that function buys the time, necessary project and check payment imports to determine whether to sell this function in key distribution source 5 in main frame.If will sell this function, user 1 is given in postcard 67 mailing that generate the key information of the use restriction be used for removing function and filled in the restriction cancellation key.Perhaps, the mail 68 of having filled in the restriction cancellation key is being sealed in 69 sealing and mailing or by facsimile transmission.
Fig. 6 shows the processing example of the application that is used for the receiving function purchase of issue cipher key source 5 execution.Be used for the processing of the application of receiving function purchase at this, receive this at step S71 from user 1 and be used for the application that function is bought.Then, next step S72 to S75 will install existence/disappearance of the convention of function, payment information and user's license contract that ID, user expectation buy successively and import main frame.At next step S76, whether the information of check input is correct.
Just in case input information is incorrect, for example, if do not provide in the function device 10 under discussion that user expectation is bought, perhaps user's license contract is not reached an agreement, and CPU enters step S78 from step S76 and is not received with the application of notifying user 1 to be used for the function purchase.
Just in case input information is correct, whether CPU enters step S77 from step S76 and checks the reimbursement of expense that is used to buy function reliable according to payment information for example.If it is uncertain to determine payment, CPU enters step S78 and notifies user 1 not receive the application that is used to buy function.
If be identified for buying the payment of the expense of function is reliably, and CPU enters step S81 for buying the functional evaluation user from step S77.Then CPU enters step S82 is used to remove the use restriction of user expectation function with generation key information.Then CPU enters step S83 so that user 1 is issued the restriction cancellation key.
Particularly, the restriction cancellation key is such will rewrite order and the data that table all is set, and table wherein is set as shown in Fig. 3 A.Just in case device 10 has the function of reading such as the sense code of bar code, can be with the restriction cancellation key as sense code printing and issue such as bar code.
When receiving the restriction cancellation key, user 1 removes key to device 10 import-restrictions, as shown in Figure 5.Illustrated and installed 10 the processing routine that lifts restrictions, therefore by doing like this, the CPU11 of device 10 will rewrite in nonvolatile memory 15 table will be set.
Fig. 3 D shows such state, and wherein as the result who buys function E, the relevant limitation function mark with function E is rewritten as " 0 " from " 1 ".Fig. 3 E shows such state, and wherein as the result who buys function F, the relevant limitation function mark with function F is rewritten as " 0 " from " 1 ".Fig. 3 F shows such state, and wherein as the result of purchase function E, F successively and G, the relevant limitation function mark with function E to G is rewritten as " 0 " from " 1 ".
Preferably, key distribution source 5 generates the restriction cancellation key in conjunction with the device ID that sends from user 1, so the restriction cancellation key is only effective in question device 10, perhaps therefore, just in case the restriction cancellation key has inadvertently passed to the third party, the third party can not use this key.
In this case, illustrate the processing routine that lifts restrictions of device 10 in following this mode, this mode is, the device ID of device 10 CPU11 check and user's 1 input of restriction cancellation cipher key separation whether with self ID, be whether the consistent restriction cancellation key of checking of device ID among the ROM13 only has been used for device 10, and if the restriction cancellation key not only be used for device 10 rewrites so be provided with table with releasing to only using the restriction of in question function.
Distort forbidding for the confidentiality that promotes the restriction cancellation key, the restriction cancellation key is preferably encrypted to issue the restriction cancellation key of this encryption in key distribution source 5.In this case, the restriction cancellation key of CPU11 decode users 1 input of device 10 is to carry out the aforementioned processing that lifts restrictions.
The situation of wherein using mobile telephone terminal to issue and obtain the restriction cancellation key illustrates now.
In said method, the restriction cancellation key that the user has obtained by mail or fax to device 10 inputs by letter/characters input method.In addition, in order to promote confidentiality and to forbid distorting, the restriction cancellation key has to increase redundant.The result is the information capacity of the increase of restriction cancellation key.Therefore, the user has to import long word mother/character string as the restriction cancellation key, and wrong risk is easy to increase in the input simultaneously.
Therefore, such method is simple and effective, portable terminal wherein has radio communication function and infrared communication function, particularly use radio communication function to buy function from the application of key distribution source, obtaining the restriction cancellation key from the key distribution source, and the restriction cancellation key that wherein will obtain like this sends to device 10 by infrared communication function.
For this portable terminal, the mobile telephone terminal with infrared communication function is preferred.Mobile telephone terminal with infrared communication function is widely used.If be loaded with the Web browser function, mobile telephone terminal can be connected to the Web website to obtain information.In addition, by infrared communication function, mobile telephone terminal can be operated as long-range commander (long-range controller) and control TV receiver or audio frequency apparatus, perhaps directly sends image information to other mobile telephone terminals.
Fig. 7 shows in order to allow user applies 5 buy functions send the mobile telephone terminal with infrared communication function that the restriction cancellation key that obtains like this uses to device 10 to obtain the restriction cancellation key from key distribution source 5 situation from the key distribution source.
As shown in Figure 2, device 10 has infrared communication function and can receive order and data by infrared ray.
The server 90 in key distribution source 5 has the web content (application) corresponding to the Web browser function of mobile telephone terminal 2.The user can connect application by mobile telephone base station 6 to server 90 from mobile telephone terminal 2 and buy function to obtain the restriction cancellation key.
Fig. 8 shows the example of obtaining processing of the restriction cancellation key of this situation.Obtaining of the restriction cancellation key of this example handled in 40, user device ID of recognition device 10 at first in step S41.In next step S42, the user with mobile telephone terminal 2 be connected to server 90 and, in next step S43, to the device ID of mobile telephone terminal 2 input medias 10.
Server is by the fact of device ID authenticate device with notice mobile telephone terminal 2 notices in step S44.
The user receives that he expects function and the payment information bought to mobile telephone terminal 2 inputs in this notice back.Among the step S46, server side confirms input information, and generates and sends (issue) restriction cancellation key in next step S47.
Among the step S48, the user receives (obtaining) restriction cancellation keys by mobile telephone terminal 2 and enters the infrared communication function of step S49 by mobile telephone terminal 2 and sends these restriction cancellation keys from this mobile telephone terminal 2 to device 10.
By this restriction cancellation key, the CPU11 of device 10 rewrites in nonvolatile memory 15 table is set.
Utilize this method, the user can easily apply for buying function to obtain the restriction cancellation key, even do not have under the situation of the function that is connected to network at contingency device 10.In addition, the user can import the restriction cancellation key that obtains like this to device 10 easily and reliably, can not produce input error.
And, if having, the user buys the required information of function, he can apply for buying function to obtain the restriction cancellation key, even he is a long way off, as when he goes out.In addition, he can preserve restriction cancellation key that obtains and the risk of therefore not losing the restriction cancellation key that obtains in the storer of mobile telephone terminal 2.
As the alternative method of off-line procedure, but tectonic system makes the user pass through such as the method for Email and by using PC (PC) to buy function to obtain the restriction cancellation key from the key distribution source to the application of key distribution source.
In this case, in order to send the restriction cancellation key that PC obtains from PC to device 10, the user is by being connected to device 10 as USB (Universal Serial Bus, USB (universal serial bus)) cable with PC.
The online issue of restriction cancellation key now is described and obtains.
Illustrate to meaning as shown in fig. 1, about at line process, compare with facsimile transmission with above-mentioned mail, it is low that device ID or restriction cancellation key are delivered to third-party risk, but the confidentiality of while lifting gear ID or restriction cancellation key.And different with the said method that uses mobile telephone terminal or PC, device 10 can directly receive the restriction cancellation key that sends from the key distribution source, need not user's input operation.
Fig. 9 shows the example of on-line system.The device 10 of user's 1 side has above-mentioned network communication unit 27, and the server 90 in key distribution source 5 comprises system bus 91 simultaneously, is connected in system bus 91 as system controller 92, management database 93 and network connection unit 94.The server 100 of Shinpan (credit card) company is connected to wide area network 8.
In this system, provide the button of the server 90 that is directly connected to key distribution source 5 to operation input block 22 as device 10.By pushing this button, Web browser is imported with coupling arrangement 10 and server 90, therefore obtain the processing subroutine and can on device 10, obtain the restriction cancellation key by the restriction cancellation key shown in Figure 10 to 12.
That is to say, utilize this restriction cancellation key to obtain and handle the embodiment of subroutine, import Web browser, on display unit 24, demonstrate inlet image 151 shown in Figure 13 at step S111 if push above button.
On the inlet image 151, two menus " equipment registration " and " function is bought and issue again " have been shown.Bought function if buy back user's first time from device, he at first selects " equipment registration ".
Obtain at the restriction cancellation key and to handle in the routine, in step S111 behind the demonstration inlet image 151, whether check has selected equipment registration still to select the function repurchase and redistribute in step S112.If selected equipment registration, CPU enters step S113 and handles to carry out equipment registration.
At this moment, device 10 sends the device ID that encrypts like this according to the device ID of default cryptographic algorithm encryption device 10 and to server 90.Then this server reception and decryption device ID are with register device 10 in management database 93.During this time interval, demonstrated the effect that the processing of registration is carried out at display unit 24.
When the location registration process in the server 90 when stopping, the restriction cancellation key obtains to be handled routine 110 and gets back to step S111 to show inlet image 151 from step S113.
After device 10 registrations, the user selects " function is bought and redistributed ".When user's selection function was bought and redistributed, the restriction cancellation key obtained the processing routine and goes to step S121 to show the application image 152 shown in Figure 13 from step S111 by step S112.
In application image 152, two menus " license key purchase " and " license key redistributes " have been shown.License key is the restriction cancellation key.Redistributing of license key means the relevant restriction cancellation key of function that redistributes with the previous purchase of user.When buying function, the user selects " license key purchase ".
