`DATA STORAGE AND ACCESS SYSTEMS
`
`This invention is gene:-oily concerned with data storage and access systems. More .
`
`particularly, it relates to a ponoble_data carrier for storing and paying for data and to
`
`computer systems for providing access to data to be stored.
`
`'E'_he invention also includes
`
`corresponding methods and computer progems. The invention is particnlariy useful for
`
`managing stored audio and video data, but may aiso be applied to storage and access of
`
`text and sofiware, including games, as well as other types of date
`
`Once problem associated with the increasingly wide use ofthe intense! is the gowing ‘
`
`prevalence of 5o—cal}e<i data pirates. Such pirates obtain data either by unauthorised or
`
`legitimate means and then make this data available essentially world-wide over the
`
`internal without authorisation. Data can be a very valuable oommodity, but once it has
`
`been published on the Internet it is difficult to police access to and use of it by interned
`
`. users who may not even reaiise that it is pirateé. This is a particular problem with audio
`
`recordings, and, once the bandwidth becomes available, is also likely to be evident with
`
`vicieo.
`
`Over the past three or four years compressed eudio sources have become increasingly
`widely available on web pages. One widely‘ used audio dale compression fon-not is MP3
`
`(MPEG3) which is an internationally defmedzstandard including a definition of
`
`compressed audio information such as speech or-music.
`
`Ii: relies on psychomzoustic
`
`_ properties of human hearing to achieve very large data compression factors. It is thus
`feasible to download usefully long passages ofzmrsic in a practically convenient short
`
`time. Pirate data suppliers have not been slow to realise the potential of this and many
`unauthorised websites have sprung up ofiering popular music including recent neieases
`by world famous hands‘ This has caused the reeorciing industry considerable concern I
`
`and there is an urgent need to find a way to address the problem ofdeta piracy.

`
`The invention described below adciresses this end reiated prebiems.
`
`According to the present invention there is therefore provided a method of providing
`
`portable data composing providing a porsebie afata smrage device comprising
`
`tiownioaded data storage means and payment validation means; providing a terminal for
`
`internet aceess; coupling the portabie data siorage cievice to the tefminai; reading
`
`-"
`
`payment information from the payment vaiidation means using the terminai; valiéating
`
`the péymentinfonnation; ami downioading data into the portable storage devieefrosh El
`
`data ‘supplier.
`
`Another aspect of the invention provides a corresponcfing mobile data retrieval device
`
`for retrieving and ousputting data such as stored music andfor noise from the éata
`
`storage device.
`
`The payment vaiidation means is, for example, means to vaiidate payment with an
`external authority such as a bank or building society. The combination of the piayinent
`vaiidatien means with the data storage zriezms allows the access to the downloaded data
`
`which is to be stored by the data storage means, to be made conditional upon checked
`
`and vaiideted payment being made for the date. Binding the data access and payment
`
`iogeiher allows the iegixirnate owners of the data to make the data availabie themselves
`
`over the internet wishoul fear of loss of revenue, thus undermining the position of data
`
`pirates.
`
`A further advantage of the system is thai it aliows users under the age of IE to make
`
`interact purchases. Cm-remly imemet users pay for goods andfor services by credit card.
`
`Si-nee credit cards cannot be Iegitimateiy be used by persons under the age of 1% (ti! least

`
`embodiment of the invention however, the payment vaiidation means comprises e-cash -

`value of transactions veiidatabie by the data storage means. in simple terms, the data
`
`I storage means can be a card which is charged up to a desired cash value (if necessary»
`
`limited to a maximum value) at a suitable terminal. This might be an intense! access
`
`terminal but could, more simply, be a device to accept the data storage card and to
`
`receive and count money deposited by the user to charge the card, writing update cash
`
`value informatiort onto the card. More sophisticateo ways of updating the cash value on
`
`the card are also possible, such as direct bank tntxtsfet. Since. with this type of
`emhoditnent, the data storage means is, essentially, preohorged with cash rather than
`acting as. a credit card it an be used by young people without the risk oftheir incurring
`large debts.
`K
`
`In one embodiment the data storage means is powered by the retrieval device when it is
`
`connected to the device and retains a memory of the clownloaded data wltencit is
`
`unpowered. This can be achieved by the use of Flash RAM or, more generally, any
`form of programmable read-only memory. Altemetively the slate storage means may
`inooqzorate a rechargeable cell or capacitor and store information in battery backed-up
`
`‘static RAM.
`
`The downloaded tlata maybe entered into the data storage device by meansof an
`
`interface such as a magnetically or wpacitativeiy coupled connection or an optical
`
`connection, but preferably the interface comprises contacts for direct electrical
`
`. connection to the storage means. The payment validation means may likewise have one
`of a variety of ioterfaoes but again preferably comprises a set of elecoical contacts. The
`
`payment validation means could‘ however comprise a magnetic or holographic data-
`
`strip such as is known for use with cmtiit cords and phone cards. The interface to
`receive the downloaded data may be separate from the interface to the pefment
`
`validation means, to facilitate separate and simultaneous access to both these systenté.
`In Dlhel’ embodiments a single interface may serve for both data storage and payment.
`
`Advantageousiy the payznent validation means includes 3 memory storing information
`to identify the person who is paying for the downloaded data.

`
`112 a preferred embodiment the
`
`retrisval'devi<:e includes an audio output and a display, to play a downloaded track and
`
`to show information about the track sndicr an accompanying video,
`
`To dowrxlcad data onto the data storage means the user can employ a data access
`
`terminal coupled to the internet. The terminal can directly validate payment - for
`
`example in the case of a smart card charged with electronic cash it can deduct a cash
`
`value from the card. Aitematixrely it call: communicate with a bank or other financial
`
`services provider to control payment. In a preferred embodiment, howevsr, the lerrninal
`
`connects to a data access service provider which provides a portal In other sites -and
`
`which validates payment and then forwards data from a daxa supplier to the users local
`
`access terminal. The data access service provider may alternatively forward payment
`validation infarmatior: arrdfor information from the paymerlt validatirm authority to the
`data sfipplier for control byjhc supplier cf the data supplied. Thus, access to the
`
`payment validasion system andfor data for downloading may be entirely commlled by
`
`rhe data supplier.
`
`Data held on the data storage means may aévamsgeously include data relatlng to the
`
`user’s er payer's usage of the systam. This information may include, for example,
`
`information on a user‘s spending pattern, informaticn on data suppliers used and
`
`information an the dawnloaded data. This inforrnarion may bevaccessed by the data
`
`supplier and/or data access ssrvéca pmvider and can be used for targeted rrinrkcting or
`
`loyalty-bsscd incentive: schemes such as air miles or the like.
`
`.
`
`The data access terminal may be a conventional wmputer er, altcrnstivsiy, it may be a
`
`mobile phone. Wireless Application Protocol (WA?) and E-mode allow mobile phones
`
`to efficiently access the imcmet and !his allows a mobile phone to be used to download

`
`data to the data siosagc means, afivantageously, direcfily. The data storage means can,‘if
`
`desired, incorpnrate the functionality of a mobile phone SFM (Subscriber Identity
`
`Module) card, which cards already include a. user identification means, to allow use:
`
`billing through she phone network operator.
`
`In pregame emhodiment the downloaded data is MP3 or other encoded auéio data, but
`the system finds more general application for other dents types. Fer example, dowrlload
`
`data can include saftware, and particularly games, share price information, current news
`
`'
`
`infonnatien, transport tfimetabk: infermation, weather infm-rnatioi: and catalogue
`
`shopping infonnation. The downloaded infcrxnation may also -include compressed
`
`video data. The storage capacity of the data storage mmns is adaptable to suit the type
`
`ofldata intended to be dewnloséed - for example, 32 megabytes is sufficient fer CDT
`
`quality music, but for video it is preferable that the data storage means has a capacity of
`
`128 megabytes or greater.
`
`In another aspect, the invention provides a portable daia csrfier compzising an interfaee
`for reading and writing data fmm and to the carrier; non-vnlatile data memory, coupled
`
`to the interface, for storing data on the carrier; nonwoiatile payment data memory,
`
`coupled to the interface, for providing payrnem data ts an external device.
`
`These features allow ‘she data carrier to store bmh payment date and content tiara thus
`l providing the advantages outlinedabove. Depending upon the paymem system used,
`
`'
`
`the p‘%ay-meat data memory may also store code for validating or canfirming a payment to
`
`an external payment system. The payment ésta will mmnally be linked to card or card
`
`holézler identification data for payment by the card holder. The non-valatiie memory
`
`ensures that stared content and payment data is retained in the data carrier when the data
`
`carrier is not receiving power from an external source.‘ Thus "non~volatile"
`
`encompasses, for example, low-power memory whose ccmtents are retained by} a baflery
`
`baek—up system. In one embodiment the payment data memary comprises EEPROM
`
`and the content data memory comprises Flash memozy, but other types of csntent data
`
`memory, such as optical, for example, "holographic, data memory can also he used. The

`
`data carrier may also be integrated "into other apparatus, such as a mobile
`
`communications device.
`
`Preferably, the poriabie data carrier further comprise: a pmgram store storing code
`
`implememabie by a processor; and 3 processor, eoispied to the content data memory, the
`payment date menwry, she’ interface arid lathe progam store for implementing code in
`
`the program stare, wherein the code cempzi ses eorie to output payment data fi-om the
`payment date memory to the interfacesnd code to provide extemai access to the data
`
`memory.
`
`Normaiiy, the (content) data memory snows hath write arid read access for both storing
`anti retrieving data, but in some embcciiments the content data memory may be read‘
`
`oniy memory. In such embodiments, content may be pmioacied onto the carrier and
`
`payment may then be made for permission to access the pie-ieadeé data.
`
`' Preferably, the data carrier also stores a record of access made to the content data and
`
`updates this in response to extemai access, psefetabiy read access, made to, the data
`
`memory. The canrier may aiso store comentuse rules pertaining to aiiowed use sf
`
`stored data items. These use mies may be linked to payments made from the card to-
`
`prcvide payment options such as access to buy content data euhighi; rental access to
`
`content data for s time peg-ice or far 3 specified number of access events; andler
`
`remailpurchase, for example where rental use is provided I0g€Ih8I"\A?ith an option in
`purchase cement fiata at the reduced price afier rental access has expired.
`
`Thus where the date carrier stores, for exampie, music the purchase outrighti caption may
`_ "be equiveiem to the puzehsse ofa compact disc (CD), prefer-abiy with sonic form "of
`content copy protection such as digits} watermarking. In this exsriipie, the rental or '
`
`'
`
`subscription payment uptien may be a pay-per-play option, ans with this option payment
`
`may either be before or after access to the stored data 50 that the carrier may operate in

`the stone data can be tracked whilst ofiliine and then any necessary payment can be
`
`made when the data carrier is next coupled to a eemmuiiicatien system. Tilis allows the
