Mobile broadcast television services different in a large number and broadcast standard be available or following it is contemplated that, all of which can realize and benefit from each embodiment.These services and standard include Open Mobile Alliance mobile broadcast and are served by external member (OMABCAST), MediaFLO, DVB IP data broadcast (DVB-IPDC) and China's Multimedia Mobile broadcast (CMMB).Typically, mobile broadcast transmission is encryption so that can sell the access to program based on subscribing or paying per view by.Can use number of mechanisms that decruption key is linked to reservation to buy.Typically, mobile broadcast service utilizes unicast communication network (such as, the cell phone data service of consumer), move equipment to/from particular consumer and transmit reservation message, and mobile broadcast service utilizes independent radio network to come to all mobile device broadcasts TV programs.Sum it up, mobile broadcast service provider can send the message including information, wherein this information makes mobile equipment can produce to receive the decruption key required for specific broadcast.Decruption key can be configured to after predetermined time amount to expire, so as to realizes paying per view by service, and restriction decruption key falls into the economic impact that public sphere is caused.Additionally, it is provided that the message of decruption key can include service restrictions parameter, this service restrictions parameter can be used for being limited to the broadcast service received specific program, channel or other market segmentation.
For example, OMABCAST standard uses the long term keys message (LTKM) sent to mobile equipment via unicast networks to provide restricted-access key.Mobile equipment uses restricted-access key, the traffic encryption key (TEK) being included in an encrypted form in Term Key Message (STKM) is decrypted, wherein, Term Key Message (STKM) is broadcasted regularly on radio network.When being decrypted, TEK makes mobile equipment (such as, 2 minutes) broadcast content stream of encryption can be decrypted in short time period.When TEK expires, the access of the broadcasted content of encryption will be terminated, unless obtained new TEK.So that complete program can be watched by consumer, broadcast STKM message in order so that can use and obtain new TEK from these STKM from these LTKM long term keys obtained.
Use below OMABCAST standard terminology and message name as illustrative example to describe each embodiment.Other mobile broadcast standard uses similar message structure, and it is distinctive in that message name and to the unessential details of each embodiment.Such as, DVB-IPDC uses key management messages (KMM) in the way of being similar to the LTKM of OMABCAST standard, in the way of being similar to the STKM of OMABCAST standard, use key stream message (KSM), and use TEK in the way of being similar to the TEK of OMABCAST standard.Similarly, MediaFLO and CMMB uses encryption management messages (EMM) in the way of being similar to the LTKM of OMABCAST standard, in the way of being similar to the STKM of OMABCAST standard, use encryption codeword message (ECM), and in the way of being similar to the TEK of OMABCAST standard, use code word (CW).Therefore it provides following description is as illustrative example, and this description is not intended to embodiment or scope of the claims are limited to OMABCAST standard.For the ease of reference, in this article longer copyright management message is called long time solution decryption key message or LTKM, in this article the decruption key of relatively short-term is transmitted message and is called short-term decruption key message or STKM, and in this article the decruption key being used for the broadcasted content of encryption is decrypted is called content decryption key or TEK.
Currently, mobile broadcast TV system allows to come consumption service or content by purchase reservation coupons or integration.In other words, first user must pay to become subscriber or for coupons pre-payment, and wherein, these coupons can be converted subsequently for programme content.Such as, in typical mobile broadcast TV system, consumer often pays 1 dollar and can buy coupons.Then, stored value card is activated in a mobile device, in order to deduct coupons when user watches mobile TV program.When customer consumption falls its whole coupons, it must could watch more mobile TV program after have purchased new coupons.
Fig. 1 shows can by mobile device user for subscribing or buy the process flow diagram flow chart of the current way of mobile TV broadcast service.When creating broadcast service or content, mobile TV service provider has created one group and has used fees policy, and uses fees policy to reach an agreement (step 100) with regard to this group.Based on these fees policies, service provider creates subscriber management key (SMK) and sets up service registry (step 102).Service provider can receive request (step 104) to service subscription from user, or service provider can receive the request (step 108) bought by viewing pre-payment or temporally pre-payment coupons from user.Mobile broadcast service provider sells requested reservation or coupons (step 106,110) to requesting party user, after this, mobile broadcast service provider sends LTKM message (step 112) by unicast networks to the mobile equipment of user.LTKM includes the long term keys for the message sent via radio network is decrypted.This long term keys usually depends on subscribes or service.Such as, user can subscribe basic loyal grade, and this basic loyal grade allows these users such as only to receive basic cable broadcast channels on their mobile devices.In this loyalty grade, user may not watch Premium Channel, such as,OrTypically, by using different long term keys to contribute to channel service control between basic channel and Premium Channel.
LTKM could be included for the use of aforementioned long term keys is carried out the service regulation of control.This rule defines usage criteria and constraints, and the example generally depends on the terms and conditions of the contract between user and service provider.Such as, service regulation can in the following granted contents consumption pattern of equipment notice: the existing reservation to direct broadcast service, the PPV to live event access, the PPV of live event or recorded broadcast content is accessed, unrestrictedly the playing back of recorded broadcast content.Sending LTKM in mailing to the message of mobile equipment of specific user by unicast networks, wherein, long term keys is stored in security function (such as, the safe storage of terminal) or on smart card.Service provider broadcasts STKM (step 114) subsequently.Service provider also sends encrypted program content stream (step 115) in time constantly.STKM makes mobile equipment can watch encrypted program content.Each mobile equipment in service provider network receives the STKM broadcast flowed and the stream of encrypted content being associated.But, not each STKM necessary to deciphering content can be decrypted by each user.The viewing privilege of individual is based in the LTKM for each mobile equipment the service regulation of defined.Therefore, if the service regulation provided in LTKM allows viewing programme content, then one or more TEK are decrypted content is decoded by the equipment that moves, and are shown on mobile device display (step 116).When have purchased coupons, if LTKM rule allows viewing programme content, then before TEK being decrypted and uses it for subsequently content is decrypted, first from mobile equipment stored value card (such as, smart card), reduce coupons.But, if the service regulation provided in LTKM does not authorize the access to programme content, then the encryption TEK that would not allow for during STKM is flowed by terminal is decrypted the program to allow viewing to be associated with this STKM stream.
But, current system is issued integration to user and is carried out sales promotion or to create, with the form of reward voucher or free coupons, the ability buying power be limited.At present, mobile broadcast TV system provides a user with the sole mode of integration is transmit reward voucher when buying service to mobile broadcast TV user.Using these reward vouchers as that send to the mobile equipment of user, have the parts of substantial purchase data, be sent to user.Because these reward vouchers are distributed when user buys service, so these reward vouchers are not with specific user or customer group for target.Coupons are also sold to user by service provider.But, these coupons are only based on what the request of purchase was authorized, and current mobile broadcast TV system lacks for coupons are authorized the means separated with purpose purchase.In other words, it is necessary to request coupons, therefore current mobile broadcast TV system has no ability to the coupons that distribution is free or gives a discount.It addition, mobile broadcast TV network is not configured to send the coupons amount different from requested coupons amount.Therefore, even if content supplier or Internet Service Provider want to give loyal consumer coupons more more than its coupons bought, system is without allowing the generation of this situation.Such as, these currently limit establishment excitations such as hampering mobile broadcast service provider, network provider, in order to their consumer uses their service, promotes their unicast networks, watches their advertisement or do shopping in their shop.

In the exemplary embodiment shown in Figure 19, it is possible to transmit STKM sky program information to reduce integration to the mobile equipment 40 of user, in order to pay for buying product or service.Owing to STKM sky program information is to whole terminal broadcast, so the mobile equipment only participating in this purchase transaction just should be subject to the impact of this special payment message.This guarantees by carrying unique purchase transaction ID in STKM sky program information.All other moves equipment (its user has neither part nor lot in this purchase transaction) can ignore this STKM message simply.Figure 20 is the message flow chart of the message that can swap in method shown in Figure 19.Below with reference to both Figure 19 and Figure 20, this embodiment is described.
The process receiving and storing integration is described above with reference to Figure 10 or Figure 13.As it has been described above, during when doing shopping at supplier position (POS) place or when online shopping, it is possible to use the integration being stored on mobile equipment 40 to pay for service and product.User can start to carry out shopping conversation (step 428 in Figure 19, step 508, it is corresponding to the message 1800 in Figure 20) with retailer 50 by his/her mobile equipment 40.User may indicate that the wish being finally completed purchase, and can transmit from mobile equipment 40 to retailer 50 about the information (message 1802 in Figure 20) of stored reward voucher or integration mobile equipment 40.This message can be transmitted in online shopping session via the Internet, or this message can be transmitted from mobile equipment 40 to the POS system of retailer via multiple known transmission method, wherein said known transmission method includes, such as, near-field communication (NFC) link, the bar code of display or being manually entered of reward voucher ID.Retailer 50 may determine that whether integration may be used for this transaction and pay (determining 510).If integration is not useable for paying (step is not shown) for this transaction, then retailer 50 can allow user to use other paying means to pay, and such as uses the credit card (step is not shown).But, if retailer 50 determines that user can use integration to pay (namely, it is determined that 510="Yes"), then retailer 50 can send payment request to mobile broadcast service provider 30, (step 512 in Figure 19, it is corresponding to the message 1804 in Figure 20).This payment request message 1804 can be transmitted by the Internet 90 or another network, and this message may identify which the reward voucher, user and/or the mobile equipment 40 that provide.After receiving payment request (step 330), mobile broadcast service provider 30 can broadcast STKM sky program information (step 331 in Figure 19, it is corresponding to the message 2000 in Figure 20) to mobile equipment 40.Can transmitting STKM sky program information 2000 via radio network 80, this message is encoded into so that it can be received and decipher by the mobile equipment 40 of only this user.Mobile equipment 40 can receive STKM sky programming message 2000 (step 438), and the content of this message 2000 of double secret key in the LTKM that the integration that can use and be stored on mobile equipment 40 is associated is decrypted, in order to determine whether LTKM rule allows to access STKM sky programming message 2000 (determining 422).If LTKM rule allows to access STKM sky program information 2000 (namely, determine 422="Yes"), the wallet that then can store integration wherein sends this message (inside story 2002), and can reduce integration (step 434) from this wallet.Once decrease integration, it is possible to send checking message (step 436 in Figure 19, it is corresponding to the message 1810 in Figure 20) to mobile broadcast service provider 30.This checking message 1810 can be transmitted via unicast networks 70.Mobile broadcast service provider 30 can Receipt Validation message 1810 (step 334), and paying response message (step 336 in Figure 19, it is corresponding to the message 1812 in Figure 20) can be sent to retailer 50.Paying response message 1812 can be transmitted via the Internet 90 or another network.Retailer 50 can receive paying response (step 514), and wherein, to retailer 50, this paying response notifies that integration is successfully reduced so that retailer 50 can be finally completed sale.It is then possible to via any of financial transaction mechanisms, settle accounts accumulated point exchanging (step 338 in Figure 19, step 516, it is corresponding to the message 1606 in Figure 20) between mobile broadcast service provider 30 and retailer 50.
If mobile equipment 40 or can not should not access STKM sky program information 2000, then move equipment 40 and can ignore this message.As a result, integration will not be reduced and checking message 1810 will not be sent to service provider 30.Owing to mobile broadcast service provider 30 is not received by checking message, so it is by transmission paying response message 1812, wherein this message 1812 notifies not shift integration to retailer 50.In this case, retailer 50 can refuse integration or reward voucher, and can ask user that service or product are used the paying of another form.
Specific rule can be defined and carry out the use of control integration.Such as, integration can include the expiration data or only can be only used once.For illustrative purposes, following instance relates to the use of reward voucher, but, the scope of the present invention is not limited to the integration of this form.Figure 21 is the process flow diagram flow chart for identification from the stored value card of mobile equipment 40 and the embodiment method deleting the reward voucher that expires.Reward voucher can be received (step 2100) by mobile equipment 40, and can be stored in (step 2102) in memorizer.Receive the request (step 2104) using reward voucher it is then possible to moved equipment by this.As set forth above, it is possible to receive request with the form of LTKM or STKM from broadcast service provider 30.When accessing reward voucher in response to LTKM or STKM, before allowing to use reward voucher, mobile equipment 40 may determine that whether this reward voucher expires (determining 2108).If (namely this reward voucher expires, determine 2108=" YES "), then can delete this reward voucher (step 2112) from memorizer, and can send about the report (step 2114) deleting the reward voucher that expires to mobile broadcast service provider 30.Can be transmitted this about the report deleting the reward voucher that expires via unicast networks 70.If reward voucher not yet due (namely, it is determined that step 2108="No"), then can be applied to carry out buying (step 2110) by reward voucher based on above-mentioned received LTKM or STKM.
Figure 22 is the process flow diagram flow chart for identifying and delete the example embodiment method using reward voucher.Reward voucher can be received (step 2100) by mobile equipment 40, and can be stored in (step 2102) in memorizer.Equipment can be moved by this to receive the request (step 2104) using reward voucher.As set forth above, it is possible to receive request with the form of LTKM or STKM from broadcast service network 30.When accessing reward voucher in response to LTKM or STKM received, reducing reward voucher with before purchase-transaction is paid, mobile equipment 40 may determine that whether this reward voucher has been used or be replicated (determining 2200) in the past.This determine enable reward voucher is defined as so that they can be used only once by any user, can everyone uses once, can be used multiple times or can use according to other use pattern that reward voucher founder envisions during the sales promotion period by any user.If (namely this reward voucher has been used or was replicated in the past, determine 2200=" YES "), then can delete this reward voucher (step 2112) from memorizer, and deletion report (step 2114) can be sent via unicast networks 70 to mobile broadcast service provider 30.If reward voucher had previously been not used by or be not replicated (namely, it is determined that step 2108="No"), then can be applied to carry out buying (step 2110) by reward voucher based on above-mentioned received LTKM or STKM.
Although the description of previous embodiment relates to the mobile equipment communicated via unicast networks with mobile broadcast service provider, but can also use other communication link.For example, it is possible on the basis without departing from claim and the scope of the present invention, these message are sent to the server pools in mobile broadcast service provider network via Anycast (anycast) network service.
Although previous embodiment is via long time solution decryption key message (such as, LTKM) reward voucher or coupons are transmitted to mobile equipment, and control to reduce reward voucher or coupons via short-term decruption key message (such as STKM), but claim can contain the realization using special coupon transactions message, and wherein said special coupon transactions message is currently not a part for known mobile broadcast standard.If these standards are modified to include special coupon transactions message, then these message should include short-term described herein and many elements of long time solution decryption key message, and can be similar to described short-term and long time solution decryption key message processes.
By using public key encryption and reward voucher being signed electronically, user and/or retailer can verify that when without contacting original release side reward voucher is believable, or can store the duplicate of all reward vouchers issued respectively.In one embodiment, reward voucher only can be organized and be issued by individual or user and use, and can not be reused by other people.In these cases, summary in many purposes signature 618o can not only cover the full content of reward voucher object, but also the account identity being authorized to the user's (or user's group) to use this reward voucher can be covered, and the other side of this reward voucher record.When using digital signature technology that reward voucher is authenticated, it is possible to detect that the reward voucher that third party attempts submitting to is not issue for him or she easily, this is because described signature will not verify this uncommitted account identity.
In one embodiment, it is possible to use X.509 signature hierarchy forms many purposes signature 618o.X.509 it is the known ITU-T standard for PKIX, especially, this standard specifies the form for public key certificate and Certification Path Validation algorithm, wherein this algorithm make recipient be able to confirm that this signature is that the authorized organization that trusted by root X.509 authorized organization generates.In a word, this digital signature is obtained by certificate chain, and wherein, each certificate points to higher certificate, and this certificate chain is pending in the X.509 certificate of the stored trust in coupon redemption side.By utilizing X.509 authorized organization, root X.509 authorized organization can authorize other company to issue effective reward voucher by distributing sub-certificate.Use this mode, reward voucher checking entity can issue company's distribution reward voucher signing certificate of reward voucher to hope, these companies can issue sub-certificate to each commercial unit or department subsequently, and wherein this each commercial unit or department use these certificates to issue the reward voucher that can verify that.Retailer's point of sales system or retailer server 50 (showing the reward voucher using the digital signature of hierarchy of X.509 signing to verify to it) can use the checking certificate of the high-speed cache provided by X.509 authorized organization that reward voucher is verified, and set up trusting relationship without with each issuing preferential tickets side.Therefore, the use of digital signature (it uses X.509 signature hierarchy to be formed) can enable Retailer system verify reward voucher when they trust X.509 authorized organization, thus greatly simplifying the exchange of the reward voucher transmitted according to each embodiment.This makes Retailer system when without communicating with issuing preferential tickets side, reward voucher can be verified.
In one embodiment, it is possible to create and there is the reward voucher of digital signature, and via mobile media broadcasting network, these reward vouchers can be broadcast to mobile equipment 40.Figure 23 illustrates the embodiment method for broadcasting the reward voucher with signature.In one embodiment, retailer server 50 can create and include the access information for reward voucher acquisition (such as, URL and reward voucher ID) reward voucher template (step 2302), and this reward voucher template (step 2304) can be sent via the network of such as the Internet to mobile broadcast provider 30.Mobile broadcast provider 30 can receive this reward voucher template from retailer server 50, and it is encrypted and broadcasts (step 2306).Mobile equipment 40 can receive reward voucher template (step 2308) of this encryption from broadcast transmission.Mobile equipment 40 can by using TEK that this reward voucher template is decrypted (step 2310).As set forth above, it is possible to obtain this TEK according to mobile equipment 40 from LTKM and the STKM that mobile broadcast provider 30 receives.If this moves one of the target receiver that equipment is broadcasted reward voucher, then this moves equipment 40 and can receive the TEK (by LTKM and STKM method) enabling this equipment that reward voucher template to be decrypted.If this moves the part that equipment is not the targeted group of this reward voucher, then this moves equipment 40 and cannot have corresponding TEK, and therefore this moves equipment 40 and will not be able to this reward voucher template is decrypted.Once reward voucher template has been deciphered, mobile equipment 40 just can pass through to use the Internet 90 (such as via unicast networks) to ask spendable electronic coupons, in order to uses reward voucher to access information and accesses the website (step 2312) that retailer server 50 is presided over.
In this embodiment, retailer server 50 can serve as coupon data thesaurus, and wherein this coupon data thesaurus can receive the request (step 2314) for electronic coupons of the mobile equipment 40.Retailer server 50 can connect via open the Internet, sends for equipment identity information and the request (step 2316) not having any coupon data transmitted in initial request to mobile equipment 40.Mobile equipment 40 can receive the request (step 2318) for identity and coupon data via the Internet 90, and as response, sends requested data (step 2320) to retailer server 50.This mobile equipment identity information can be any type of information identifying this equipment and/or user to retailer server 50.The example of this information includes: device identifier is (such as, MACID), equipment telephone number, user account, membership numbering, user name, secret number (such as, Personal Identification Number (PIN)) that the retailer server 50 that is stored in device memory is known etc..During concluding the business, it may be necessary to it is one or more that mobile equipment is submitted in these device identifiers.
Can use different methods for sending equipment identities data to retailer server 50.For example, it is possible to automatically send equipment identities data (such as, in response to the request to this information) to retailer server 50.In this implementation, mobile equipment 40 can be configured to provide requested identification parameters in the answer message going to retailer server 50, and retailer server 50 is automated toed respond to.Or, mobile equipment can inform the user this request, and it is only after user indicates, and just sends equipment identities data to retailer server 50.In this implementation, mobile equipment 40 can be configured to inform the user the request to identity data from retailer server 50, and point out this user to agree or disagree with and send requested data, and and if only if its receive allow to retailer server 50 transmit the user of this identity data input time, just respond.
Retailer server 50 can use this identity data and coupon data to create the reward voucher (step 2324) including digital signature.Digital signature summary can include requesting party's equipment identification information and reward voucher ID.Have and the certificate associating the hierarchy of X.509 signing returning to root X.509 authorized organization as set forth above, it is possible to use, generate digital signature.As described below, it is possible to use the digital signature together with facility information and reward voucher ID at point of sale place, in order to before accepting reward voucher, verify the true and false of this reward voucher.The verification method at point of sale place it is more fully described below with reference to Figure 25.Retailer server 50 can send signed reward voucher (step 2326) to broadcast suppliers 30.Broadcast suppliers 30 can use unicast networks that from retailer server 50, this signed reward voucher is relayed to mobile equipment 40 (step 2330).Or, via the Internet 90, retailer server 50 directly can send this signed reward voucher to mobile equipment 40 via open communication link.Mobile equipment 40 can receive and store this signed reward voucher (step 2330), and can inform the user and have received the electronic coupons (step 2332) that can use in transaction now.
In an alternative embodiment, reward voucher template is not to provide URL, but can include different communication indicator or address, such as telephone number.In this embodiment, mobile equipment 40 can communicate with retailer server 50 with switching equipment identity, and receives signed reward voucher via communication network (such as, using SMS or MMS communication method).
Figure 24 illustrates another kind of embodiment method, and wherein, retailer server 50 can be created for the signed electronic coupons to mobile equipment 40 broadcast by the method, is encrypted without to this broadcast reward voucher.In this embodiment, retailer server 50 can use the endorsement method of routine to create the reward voucher (step 2402) with digital signature, wherein this digital signature covers coupon data, reward voucher ID and intended recipient mobile equipment identity data (if it is known that words), and retailer server 50 can send this signed reward voucher to mobile broadcast provider 30 to carry out broadcasting (step 2404).There is the certificate associating the hierarchy of X.509 signing returning to root X.509 authorized organization to generate digital signature as set forth above, it is possible to use.Such as previous embodiment, mobile equipment identity data can include any one or more device identifiers, such as, and equipment MACID, telephone number, PIN, account or group number.Group number (that is, group ID) can be assigned to mobile equipment 40, and wherein this moves equipment 40 as by the group contacting or add alternately or be assigned to mobile equipment or user with retailer.Such as, retailer can have regular guest and reward program, wherein uses this program, and user can contract and receive group identifier, and this group identifier can be stored in the mobile equipment of this user for receiving electronic coupons.In this example, retailer can issue signature has consumer to reward the Broadcast Electronic reward voucher of program identifier so that the consumer only registered just can receive, via radio network, the reward voucher that can cash.
Mobile broadcast provider 30 can receive this signed reward voucher from retailer server 50, and it can be used as the part that common broadcast is transmitted to carry out broadcasting (step 2406).In this exemplary embodiment, before signed reward voucher is broadcasted, it need not be encrypted by broadcast suppliers 30, this is because the reward voucher that digital signature may be used for checking user and retailer server uses, to guarantee that only specifically moving equipment receives and process this reward voucher.
In order to receive digitally signed reward voucher from retailer server 50 and it is decrypted, mobile equipment 40 can carry out pre-registration to retailer server 50.As a part for pre-registration, retailer can carry for use in the decruption key of storage on the mobile equipment of user.This decruption key can be the standard public solution decryption key that retailer server 50 is shared with mobile equipment 40, such as, X.509 verifies certificate.It addition, during this pre-registration procedure, mobile equipment 40 can share device data with retailer server 50.This device data that retailer server 50 can receive during storing and be used in pre-registration, in order to creating the reward voucher including having this data of digital signature, wherein this data signature includes device data and coupon data.The method makes it possible to generate the electronic coupons that can be only used by specific mobile equipment, this is because only can verify this digital signature with this device data.This allows to broadcast, by radio network 80, the reward voucher being awarded to each user or less user group in unencrypted mode.
After receiving the digitally signed reward voucher (step 2408) broadcasted, reward voucher signature is decrypted (step 2410) by the decruption key that mobile equipment 40 can be used in receiving during pre-registration.By signature is decrypted, mobile equipment 40 can access the signed data of encryption (such as, coupon data) (step 2412), and may determine that whether the ID obtained from this signature matches (determining 2414) with the ID of storage this equipment.When using that X.509 signing certificate is to generate digital signature, mobile equipment can also verify that this reward voucher is the issuing entity trusted by root X.509 authorized organization, and is therefore issued by reliable businessman.The mobile equipment without suitable decruption key can receive reward voucher broadcast, but will not be able to this signature is decrypted, thus these data will be ignored.
If (namely the device data received in this signature and mobile device data match, determine 2414="Yes"), then move equipment 40 can be stored in by this reward voucher in this memorizer moving equipment 40 (step 2416), and inform the user have received be currently available for transaction electronic coupons (step 2418).If (namely the device data obtained from the signature of deciphering does not mate with mobile equipment 40 data, determine 2414="No"), then move equipment 40 and can ignore this reward voucher (step 2420), this is because this reward voucher is not intended to move equipment 40 for this.If additionally, mobile equipment 40 does not have, and reward voucher signature is decrypted required decruption key, then moving equipment 40 and can ignore the reward voucher received.The various combinations of encryption and digital signature can be used in a similar fashion, to organize, to specific user or user, the electronic coupons that offer can verify that via mobile broadcast network, without the encryption method (such as, LTKM and STKM method as described above) using broadcaster.
Digitally signed reward voucher can be exchanged in many ways at point of sale (POS) place of retailer.Such as, the type according to reward voucher, it is possible to buy commodity by discount or free mode at point of sale place.Figure 25 illustrates the embodiment method for exchanging signed reward voucher during being in purchase-transaction in point of sale.During this sales transactions (such as, in " paying the bill " period), user can show storage to POS system 95 the mobile equipment 40 of signed reward voucher.Mobile equipment 40 and POS system can negotiation communication link (such as, use known near-field communication (NFC) link), wherein by this communication link, mobile equipment can send electronic coupon data and equipment identities data (step 2502) subsequently.POS system 95 can receive this signed reward voucher and equipment identities data (step 2504), and can send for asking the request (step 2506) that the reward voucher that this is signed is verified to retailer server 50.
Checking request message from POS can include reward voucher signature, reward voucher ID and the equipment identities data received.Retailer server 50 can receive this checking request message (step 2508), this signature is decrypted (step 2510), and the reward voucher ID obtained from signature and equipment identities data are compared (step 2512) with from the POS reward voucher ID received and equipment identities data.When digital signature is to use that X.509 signing certificate is to generate, retailer server 50 can also verify this reward voucher be whether the issuing entity trusted by root X.509 authorized organization and therefore issued by reliable businessman.If digital signature having been carried out correct deciphering (this confirms that publisher is credible), and the reward voucher ID obtained from this signature and equipment identities data and those reward vouchers ID received from POS system checking request message and equipment identities data match are (namely, determine 2510="Yes"), then retailer server 50 can verify this reward voucher (step 2514).
A part as checking reward voucher, retailer server 50 can also at coupon database (such as, inefficacy reward voucher list object as described below) middle lookup reward voucher ID, to determine whether this reward voucher is converted, and can check that reward voucher field is to determine whether this reward voucher has expired.If this reward voucher has been verified by digital signature, and data record indicates it but without being converted and also not expiring, then retailer server 50 can send checking message (step 2516) to POS system.POS system can receive this checking message (step 2518), and this reward voucher is applied to purchase-transaction (step 2520).POS system can send reward voucher to retailer server 50 alternatively and use message, in order to notify the use (step 2522) of this reward voucher to retailer server 50.POS system can also send reward voucher to mobile equipment 40 and cancel message (step 2526).Retailer server 50 can receive this reward voucher and use message (step 2524), and this reward voucher ID exchanged in record.Mobile equipment 40 can receive this cancellation message, and deletes this reward voucher (step 2528) from memorizer.
