OPTIMISED M1SSAGSS CONTAINING BARCODE INFORMATION FOR MOBILE RECEIVING DEVICES Optimised Mobile Barcode Messages The present invention relates to coupons, in particular delivering coupons containing barcodes to a mobile device. The display of a mobile device may be used to ge-arate bar codes for reading by a conventional bar code scanner. This has uses in coupon and ticket applications. The mobile solution has a number of unique aspects v\en compared to traditional methods such as paper cr internet email. These include: - Instant Delivery. The barcode is delivered to ne mobile phone almost iirjnediately, - Reach. The consumer can be reached wherever t- - are. - Increased Redemption. Unlike paper coupons wh . may be left behind, a mobile phone is normally csrriec everywhere. G3 Patent .Application Number G32361570 to Briti. Airways discloses a method of operating a ticketing Sys- . A reservation centre generates data representing • icket which is broadcast to a mobile station e.g. a c- ilar CONHRMATIONCOPY phone. The data from the mobile station can then be used to verify t,ne transaction e.g. via a reader linked to a reservations computer. The tickst data can be sent in the form of a text e.g. SMS message or in brovjser readable format and is preferably in machine readable code. Preferably, the reader is an optical bar or - pin code reader. The system is preferably used for air travel. The problems with the disclosed system are that: - There doesn't appear to be a way of enforcing single redemption of a ticket (for security) . - It relies on a "SIM toolkit" application in the handset to translate the ticket number into a barcode image. It would be advantageous to deliver the actual barcode image in the message. The SIM toolkit has a number of problems. Many network operators discourage or prevent downloading of applications into the SIM card. SIM storage is limited and it's harder to update the software on all of the phones. International- Patent Application number WO 01/95267 to Nokia relates to the*provision of goods and services," * Receipt data corresponding to a purchase of predetermined goods or a service are downloaded to a mobile handset and displayed as a bar code. A vending delivery station receives the receipt data from the handset and enables the provision of the purchase goods or service to the customer. In one example, cinstuS tickets are DrovM-*4 printed by a ticket printer- The problem with the system is that it requires the consumer to collect tickets which are printed by a vending station before entry. It wculd be advantageous to simply treat the phone / barcode as a ticket which is scanned at the actual entry point, t*us eliminating the queueing / inconvenience and printing. The publication discloses MPEG film previews when browsing the cinema options. This is net however included as parr of the ticket. It would be advantageou-s to provide multimedia tickets to phones that can support their viewing. G3 Patent Application Number GB2362012 to IBM discloses Paying for goods and services without needing zo carry nany cards. A customer, who has registered infr. rmation such a credit card number with a server, receives payment information as an identification code when he/,me pays for a purchase at a store. The payment information can be transmitted wirelessly to the cash register in store, or displayed as a two-dimensional barcode on disp.. -.y of the terminal and read by a barcode reader of the c; h register. The payment information is -associate:; with sales information and sent to the server which ssociates the payment information with the registered in: rmation for the customer, seeks approval from the appr-, riata credit institution, and sends an approval numbf to the store. A ticket processing system embodiments . also described. The problem with both the Nokia and ISM system:. s that they don't facilitate operation with a variety phones with different messaging formats and display o,. corarrunication cspabi.Uti-23. For exainpls, it wo. be advantageous fcr one system to support mobile r. ;es that do cr do not support "Picture Messaging" or Blv ooth.

In order to provide a better understanding of the prerent invention, an errbodinisnt will now be described by way of example only and with reference to the accompanying Figures, in which: Figure 1 illustrates, in schematic form, the core technology platform in ^ccord^nce --nt-h rno nrP,-.^^ invention; Figure 2 illustrates, in schematic form, the core mobile barcode generation, delivery and redemption process in accordance with the present invention; Figure 3 illustrates, in schematic form., the redemption architecture and process in accordance with the present invention; Figure 4 illustrates, in schematic form, the mobile barcode generation, delivery and redemption process customised for the retail coupon market; Figure 5 illustrates, in schematic form, the mobile barcode generation, delivery and redemption process customised for ticketing applications; Figure 6 illustrates, in schematic form, the race-tie barcode generation, delivery snd redemption prc:~ss customised for security applications; The invention is a platform that functions to c.z iver coupons to a mobile device. Typically the coupe - contain barcodes tn~- •are redeemed by scannincr th= rii^-' ■- ^f M-,P ncbila device. With reference to Figure 1, the application 102 interfaces to the core technology platform 104 : -advanced mobile messaging using XML content d»"> ^-T-PH over the internet http protocol. a hvooage .^IOC^-^O^ J.L^ J.^ o^arcsc aurcntaticaiiy in response to the delivery of .ir^ssage content to a specified URL. The message processor receives the mobile phone number, barcode number and syrnbclogy, handset/device type and additional message content for delivery to the device. The handset/device type is optional. When it is provided, it is stored in the database against the mobile number. In the case of future messages for that mobile number where the device type is not .provided, then the recorded device type is retrieved. This avoids the need to capture the handset/device type or. multiple occasions or for different purposes such as coupon or ticket delivery. The message content is provided in XML format, and delivered using the http post protocol. The XML is a list of messages containing information including: - Mobile phone number - Barcode number and syiriology - Additional text content (optional) - Recipient details such as Name (optional) - Handset and Network details (optional) The Message Processor 106 processes the messages and stores them in the database for retrieval by the Queue Control "i »>* i "■ $ The Barcode 5::wC-der 103 is invoked to ce^\^= hrrccna images from -he barcode number ar.ci syrnbolcgy. The imaaes are stored as Pictures in the database 110. Customer systems can be integrated with the mobile messaging platform through the message processor 106. The database 110 stores the following core entities: ' * - Barcodes - Barcodes with a particular number and symbology - Pictures - Pictures (may represent a barcode image) - Handset - information on a particular handset including owner details, mobile number, model, etc. - Messages - Outbound and inbound messages - Gateways - Network messaging gateways The barcode encoder 108 generates the barcode i:~age for a . specified barcode ar.d symbology. The resulting picture is stored in the database 110 in binary form. The encoder supports both linear barcodes such as EAN-8, E/V.-13 upc- •" A, etc. as well as 2D barcodes such as DataMatr:.>: P3F-417, etc. •A similar approach can be used for other advance message types such as smart tickets. The Message Engine 112 starts a separate queue . .itrcller 114 for each message priority level (1-3). The ssage engine 112 also starts the gateways 120. The Queue Controllers 114 poll the database lie periodic intervals to retrieve all rr-essages wit -.he relevant prion.y* The messages are then fed th.. :~h r'no Message Opt.inissr 115 and Message Routers 118 -- out through ths selected gateway 120. The Message Optimiser 116 chcos^s the optimal message format depending on the capabilities of the target handset.- For basic handsets, a. simole text messaae will be delivered. Otherwise, subject to the handset supporting the required display dimensions and colour depth, pictures are delivered using the richest format available. The Message Optimiser 116 overcomes many of the problems inherent with known methods. In particular,, the wide range of device types/models arid message protocols restrict rr.any alternative solutions to providing support for only a limited number of users. Devices can vary in cheir support for particular picture messaging protocols such as Nokia Smart Messaging cr EMS (Enhanced Message Service) . Device display capabilities such as display resolution also constrain the barcode symbologies and codes that may be represented. The present invention enables a comprehensive support of the installed base of devices to be orovidecL Ikl The Message Optimiser 116 takes the barccde image generated by the Barcode Encoder 108, and device type and optimises the messages for transmission based on the capabilities of the target handset. "■vhere the target device dees net; have sufficient capability zr. r^r.eive or represent the mess-jicye correctly, the concern: is downgraded accordingly. Ultimately, for a handset that supports only SMS text messaging, then the barcode number and associated text is transmitted. E.g. xx3arcode . Ticket fcr Event at Venue on Da:a". In the case of a text-only barcode, the barcode is redeemed by keying-in the number. This is also the common, automatic approach when * barcode image fails to ** '"* P T\ . The downgrading of the content is controlled bv a hierarchy of rules based on the device capability. This includes: 1. MViS support 2. EMS support 3. Nokia Smart Message support 4. Display Resolution If the display resolution is insufficient to represent the barcode, then the message is downgraded to text. A table of device attributes associated with a device .-■*•■ type is maintained ir. the database 110. This table includes the following information; 1. Handset/Device Type 2. MMS Support 3. EMS Support 4. Nokia Smart Message Support 5. Display Resolution 6. Colour Depth (1 = mono) 7. Bluetooth support 8. Java support Where the handoac model is not kr:own, then the capabilities of -he database device entry with id of "DSFAULT" are s?suited. This enables such behaviour to be controlled, i.e. whether to assume ths^cr. unknown handset supports Nokia picture messages or not. The barcode image can also be a 20 barcode, A 2D barcode enables a larger amount of information to bs contained v:ithin the barcode. If the dsvice has a multimedia capability, then messages can also be enhanced by the addition of moving video, colour i.mages, and audio clips. Mobile phones n~y support MH5 (Multimedia Messaging Service). In this case a ticket for a music concert could include a short piece of video of the band, an image of the cover of the new album, and an audio clip for a recently released track in addition to the barcode. Similarly, in order to promote - brand, a coupon could contain, a video clip and audio f re:~ a TV advertisement in addition to the barccde. In severity applications, a photograph could be included w.;a the barcode. The message router 118 chooses the optimal net' zk gatev/ay based'on rules stored in the database. .ilticle gateway connections can be supported for load -ancing and scalability* Wheire there is ~iore than one risible route, the gateway with the lowest latency is :sen. - The gateways 120 are the route to the external ;s gateways or SMS centres over a network. The g: ays 120 maintain a queue of messages sorted bv priori: A number of different SMS gateway technologies ara SUD: ed including XML/http, SMP?, GSM terminals, etc. Alternatively .she gateway 120 can be an email ew~v, delivering the messages 52 an sir,ail message, r uires .cay be attached as a GIF image. rhe SMS gateway 122 is a gateway to the mobile network short messaging service. Alternatiyaly, this nay be a direct connection to the mobile network operator's massaging centre. The SMS gateway may support enhanced -,_., ^J-, si.cn a^ ^lCuUic messages. The SMS gateway may be a multi-media message (HMS) gateway for delivery of multimedia messages including high-resoluticp. colour images and video. The mobile handset 124 can be a mobile phone or other wireless-enabled device such as a PDA. The core technology platform 1C4 supports processes in a number of applications. Additional components are defined to support the specific steps in such solutions. Thus the ., system also may include an Autc.uatic Download exponent 126_and a Random Barcode Generator component i:: for customisation of the system as described below ."or rstail coupon and security applications respectively. with reference to Figure 2 the core mobile ba^ ■->■= generation, delivery, and redemption process 2' is depicted. The consumer cpts-in to receive barcodes by re rtaring (step 202) with the supplier. Registration may - through a variety of channels including internet web s. telephens csll centre, paper forms, or text xr.e ae. The registration details are scored in t^e d.'t ^ fet-.n 204). The da-cabase contains customer contact a1 profiling information. This information indue-- - Customer details and contact information including mobilG number and possibly r.arcs, smail address, postal address, photograph, etc. - Customer demographics including age, sex etc. - Customer preferences - Customer buying history In the Target Profile step (step 205), an offer for c product, service, or information is matched with the database of customer profiles. The matching criteria may include one or nore of: - Demographics - Preferences/Product Criteria - Buying History The result of the match is a list of rricbile numbers for ccn.tact purposes and profile information for messaae personalisation. The specified barcodes are generated from the number(s) provided and delivered (step 208) to the list of mobile numbers using the messaging platform. This step is expanded towards the right hand side of Figure 2. After inputting and storing (step 210) device attributes defining the device capabilities in the database and inputting (seep 212) a device type identifier (e.g. .-rodel cf mobile fphon=), the system generates (step 214} m-ssscge data comprising a coupon ar.d optionally the c;sv2.cs type lac-ntiiier. The system retrieves (step 21S) device attributes defining the device capabilities corresponding to the mobile device type identifier and generates (step 218) an optimised .message responsive to the msss&ge data and the retrieved capabilities. Finally in the delivery step, the system transmits (step 220) the optimised message to zha target mobile device via one or more gateways through a network. The delivery of a barcode is recorded in the database for subsequent authentication purposes. The barcode is redeemed (step 222) in the same way as any product containing a barcode, by scanning the mobile phone display using a conventional barcode scanner. An alternative to scanning the barcode for redemption could be to use Bluetooth or an alternative radio or electromagnetic transmission method. The barcode is authenticated {sz%p 224) by examining the barcode delivery records and retrieving the associated customer details. The customer details, possibly including a photograph, may be displayed on a computer display for human validation. Barcoco redemption is recorded in the database for audit purposes. s If this barcode is to b-s redeemed only once, then tha barcode record in the database is marked as redeemed, and cannot be redeemed again. With reference ;o Figure 3, the redemption process 3DD is shown. In the case of a coupon, the barcode is sent to the mobile device 302 and is ^s^eH - - • u. x» - neo flL -he outlet or venue 304, ar.a. the number i ^ M — K *-^ • J . - ~ X i, j.-^ uO identify the offer *y searching che_ database in rhe.core technology platform 104 according to the present invention. in the case of a single-redemption barcode such as a ticket, the barcode is validated against the database 305. The barcode entry in the database is then marked =.3 V-d=p-oH' x. ^ ^ >.~>J -0 ivCse,:,sci to prevent multiple redemption of the same barcode. Specific solutions based on the core technology platform are defined and will be presents* below for a number of markets: - Retail Coupons - Ticketing - Security With reference to Figure 4, the mobile barcode solution process 4 00 is customised for the retail coupon market. The mobile barcode represents a discount coupon which is • redeemed by scanning in a retail outlet. Barcodes representing discount coupons may be redeemed multiple tinas without any authentication. Indeed, viral marketing may be encouraged through forwarding of the mobile barcode to friends and family. -a :^'J^° •■' •' ancl o- sacri or ui:e steos h*v corrjnon with Figure 2 are cescn'-ed above. The Coupon Download ("pull") (step 402)_is initiated by a consumer via a number of channels including: - Web site - Telephone - Mobile text Message sent to a supplier mobile number In each case, the recipient's mobile number is captured in order that the mobile barcode coupon may ba delivered * (step 404). The solution builds on the core process with an Automatic Download component 126 shown in Figure 1. The automatic download component 126 is invoked from a web site, automated telephone system, or through receipt of a text message. The component 126 takes the mobile number and barcode number and invokes the Message Processor 106 using XML/http to deliver the mobile barcode. With reference to Figure 5, the mobile barcode solution process 500 is customised for ticketing applications. The mobile barcode represents a ticket thafis redeemed by scanning the phone display at the venue. Specific steps in the mobile ticketing solution are: - Deliver Promotional Message (step 502) - Purchase (step 504) With reference to Figure 5, the first steps (down to but not including Purchase (step 50-1)) are optional. An example promotional message might be: Ticket available for Sat. Call 0800 123455 or reply "1" The promotional message may be delivered as a simple text message, or might be s richer message including text and pictures. The purchase may be achieved through * number of channels including: - Ticket sales call centre - 7Jeb site - Text message reply Payment m.sy be received through one- of many existing . methods including credit card zr.d existing account. Whan payment is accepted, then the rr.obile barcode ticket is delivered (step 506). As the Message Processor supports simple text messages as v/ell as more sophisticated data (barcodes) , the promotional message is delivered using the core platform. The ticket purchase is achieved using traditional methods. /?ith reference to Figure 6, the mobile barcode solution process 600 is customised for security applications. The mobile barcode represents an identity that is validated by scanning the phone display. Upon validation, access can be granted to a secure location, or a product can be provided. .here is an automatic rar-doni barccds gsnerstior; steo GO 2. A new random bcrcode may optionally be generated and delivered every time a barcode is redeemed. The solution builds on the core process with the Random bsrcoca generator component 129 shown in Figure 1. The Random barcode generator 128 automatically generates a random barcode number. The barcode nuir.ber generate Key features of the solutions described herein are: - Targeting using a customer profile database - Dynamic barcode image Generation ^v-~™ u y . '■««t.on ;rcm oarcode number and symbology - Delivery of barcode to mobile phone or other wireless device - Redemption and authentication of barcode by scanning display - Specific processes for particular applications The solutions described above are implanted using Java 2 Enterprise Edition, SQL, and XML (extensible markup language). Alternative technologies could however be used to implement the solutions described above.
