`
`DATA STORAGE, RETRIEVAL AND ACCESS SYSTEMS .
`
`This invention is generally concerned with data storage, retrieval and access systems. More
`particularly it relates to apparatus and methods for mobile and/or portable data retrieval and
`use and to data storage means and to means fOr controlling access to, and paying for, data and
`to apparatus, methods and systems therefor. The invention may be used, for example, for
`providing and controlling access to MP3,, audio and compressed video data sources.”
`_
`
`.
`
`’ ““Once problemrassociated with the increasingly-udde'use"of'the‘intemet'is-the'growing " ., **'-- era-er-
`prevalence of so-called data pirates. Such pirates obtain data either by unauthorised or
`legitimate means and then make this. data available essentially world-wide over the intemet
`without authorisation. Data can be a very valuable commodity, but once it has been published
`
`on the lntemet it is difficult to police access to and use of it by Internet users who may not
`even realise that it is pirated. This is a particular problem with audio recordings, and, once the
`
`bandwidth becomes available, is also likely to be evident with video.
`
`Over the past three or four years MP3 (MPEG3 format encoded) audio sources have become
`increasingly widely available on web pages. MP3 or MPEG3 is an internationally defined
`standard for compressing audio information such as speech or music. It relies on psycho-
`acoustic properties ofhuman hearing to achieve very large factors of data compression. It is
`thus feasible to download usefully long passages of music in a practically convenient short
`
`.
`
`time. Pirate data suppliers have not been slow to realise the potential of this and many
`unauthorised website have sprung up offering popular music including recent releases by
`world famous bands. This has caused the recording industry considerable concern and there is
`
`an urgent need to find a way to address the problem of data piracy.
`
`The invention described below addresses this problem and may be able to convert this threat
`
`into a potential opportunity.

`.
`
`The payment validation means is, for example, means to validate payment Vwith an external”
`
`.
`
`authority such as a bank or building society. The combination of the payment validation
`
`means with the data storage means allows the access to the downloaded data which is to be
`
`stored by the data storage means, to be made conditional upon checked and validated payment
`
`being made for the data. Binding the data access and payment together allows the legitimate
`
`owners of the‘data to make the data available themselves over the intemet without fear of loss
`
`of revenue. This has the potential to undermine the position of the data pirates.
`
`A further advantage of the system is that it allows users under the age of 18 to make intemet
`
`purchases. Currently intemet users pay for goods and/or services by credit card. Since credit
`
`cards cannot be legitimately be used by persons under the age of 18 (at least in the UK), a
`significant fraction of adventurous intemet users are excluded from e-commerce, one of the
`
`.
`
`most significant predicted uses of the intemet. In one embodiment of the invention however,
`
`the payment validation means comprises e-cash - that is the payment Validation means stores
`
`transaction value information on a cash value of transactions validatable by the data storage
`
`means. In simple terms, the data 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
`
`intemet 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 information onto the card. More sophisticated ways of updating the cash value on the
`
`card are also possible, such as direct bank transfer. Since, with this type of embodiment, the
`
`8
`
`

`

`
`
`storage means is, essentially, precharged with cash rather than acting as a credit card it
`
`can be used by young people without the risk of their incurring large debts.
`
`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 downloaded data when it is unpowered.
`
`This can be achieved by the use of Flash RAM or, more generally, any form of programmable
`
`read-only memory. Alternatively the data storage means may incorporate a rechargeable cell
`
`of capacitor and store information in battery backed-up static RAM.
`
`,.
`
`n. _.
`
`,._ .__
`
`,
`
`The downloaded data maybe entered into the data storage device by means of an interface
`
`
`
`__such.as,amagne_tically_or.c,apacitatixelymcoupled_conne,ction_ot_.an,opti§§l.C,an99Lign,.buL,__,
`
`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 interfaces but
`
`again preferably comprises a set of electrical contacts. The payment validation means could,
`
`however comprise a magnetic or holographic data-strip such as is known for use with credit
`
`cards and phone cards. Preferably, the interface to receive the downloaded data, is separate
`
`from the interface to the payment validation means, to allow separate and simultaneous access
`
`to both these systems. Advantageously the payment validation means includes a memory
`
`storing information to identify the person who is paying for the downloaded data.
`
`For additional security the downloaded data may be encrypted. In this case data decryption
`
`may be necessary at some stage, either in the data storage means or in the retrieval device or in
`
`an information delivering apparatus such as the data access terminal. Alternatively the data
`
`decryption function can be shared amongst one or more of these devices. The skilled person
`
`will be aware of a range of suitable encryption/decryption techniques including Pretty Good
`
`Privacy (Registered Trade Mark) and PKI. Normally when the downloaded data is encrypted
`
`a decryption key must be supplied. This can be generated automatically by the data access
`
`terminal or data access service provider or it can be entered by the user into the data access
`
`terminal or into the mobile data retrieval device.
`
`The data storage means and/or the retrieval device can be provided with access control means
`
`to prevent unauthorised access to the downloaded data. Alternatively, this access control
`
`
`
`9
`
`

`

`
`
`
`/,_-.
`
`l
`
`means can be used to stop or provide only limited access of the user to the downloaded d
`
`accordance with the amount paid. Thus, for example, a complete set of data information
`
`relating to a particular topic, a particular music track, or a particular software package might
`
`be downloaded, although access to part of the data set might thereafter be controlled by
`
`payments made by a user at a later stage. Thus, a user could pay to enable an extra level on a
`
`game or to enable fiirther tracks of an album.
`
`In embodiments where the access control means is responsive to the payment validation
`
`means access control information may be stored with the downloaded data or in a separate
`storage area, forenample inthepayrnent validationmeans The user’s accessto the

`
`access or decryption control element.
`
`In a preferred embodiment the data storage means comprises an electronic memory card or
`
`smart card and the mobile data retrieval device is provided with a slot to receive the card.
`
`Preferably the card is a push—fit within the retrieval device, and retention of the card may be
`
`effected by pressure from electrical interface connections and/or resilience of the housing, or
`
`by using a resilient retaining means. In a preferred embodiment the retrieval device includes
`
`an audio output and a display, to play a downloaded track and to show information about the
`
`track and/or an accompanying video.
`
`To download data ontovthe data storage means the user can employ a data access terminal
`
`coupled to the intemet. 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. _
`
`Alternatively it can communicate with a bank or other financial services provider to control
`
`payment. In a preferred embodiment, however, the terminal connects to a data access service
`
`provider which provides a portal to other sites and which validates payment and then forwards
`
`data from a data supplier to the user’s local access terminal. The data access service provider
`
`may alternatively forward payment validation information and/or information from the
`
`payment validation authority to the data supplier for control by the supplier of the data

`
`Data held on the data storage means may advantageously include data relating to the user’s or
`
`payer’s usage of the system. This information may include, for example, information on a
`
`user’s spending pattern, information on data supplies usedand information on the downloaded
`
`data. This information may be accessed by the data supplier and/or data access service
`provider and can be used for targeted marketing or loyalty-based incentive schemes such as air
`miles or the like.

`phone. The Wireless Application Protocol (WAP) allows mobile phones to efficiently access
`
`theinternet and this allows a mobile phone to be used to download data to the data storage
`
`means, advantageously, directly. The data storage means can, if desired, incorporate the
`
`functionality of a mobile phone SIM card, which cards already include a user identification
`
`means allowing through the phone network operator, user billing.
`
`In preferred embodiment the downloaded data is MP3 encoded audio data, but the system
`
`finds more general application for other data types. For example, download data can include
`
`software, share price information, current news information, transport timetable information,
`
`weather information and catalogue shopping information. The downloaded information may
`
`.
`
`also include compressed video data. The storage capacity of the data storage means is
`
`adaptable to suit the type ofdata intended to be downloaded - for example, 32 megabytes is
`
`sufficient for CD quality music, but for video it is preferable that the data storage means has a
`
`capacity of 128 megabytes or greater.
`
`These and other aspects of the invention will now be further described, by way of example
`
`only, with reference to the accompanying figures in which:-
`
`Figure 1 shows an embodiment of a mobile data retrieval device according to the present
`
`invention, a) from the top; b) from the front; and c) from the side;
`
`
`

`

`

`
`
`
`
`Figure 2 shows an embodiment ofa datastorage means according to the present inventio.
`
`Figures 3a and b show data access terminals;
`
`Figure 4a shows a logical signal path between elements of a data providing system; and
`Figure 4b shows a physical representation of a data providing system.
`
`Referring to Figure 1, this shows a mobile data retrieval device for playing MP3 audio (10)
`
`with operator controls (12) and LCD'display (14). The outline of a smart card data storage
`
`8 device is shown at (1,6); The operator controls ‘allowlauser toselect'and‘ play tracks, whilst
`
`. track information and still or video1magesareprovidedon display (_14). A_ slot_(l8)1s___
`provided1n the front of the device to receive a smart card--type data storage means. Thissmart
`
`card occupies space (20) and interfaces with resilient contaCts (24);
`
`it is heldin the data
`
`retrieval device against the contacts, by resilient housing element (22).
`
`Referring now to Figure 2, this shows a data storage means (30) suitable for use with the
`retrieval device of Figure 1. The data storage means-is based on a standard smart card;
`it is
`
`plastic, about the size of a standard credit card, and has some flexibility. On the card (30) are
`
`two sets of contacts, contacts (32) for interfacing with the payment-validation means and
`
`contacts (34) for interfacing with the memory for stonng downloaded data. The surface of the
`
`card can be embellished with suitable graphics.
`
`Preferably the smart card retains all its useable functionality as specified for standard
`
`Electronics Point of Sale Systems (EPOSS) and, if desired, the memory for storing the
`
`downloaded data can be electrically separate from this. However, it may be preferable to
`
`provide interaction between the standard smart card device and the data memory in order to
`
`accomplish the access control/decryption functions described above.
`
`Referring now to Figure 3, one embodiment of a data access terminal is shown at (40). This
`
`has a screen (42) and a slot (44) to receive the data storage means (30). Alternatively the data
`
`storage means may interface to the terminal via the data retrieval device (10) and an interface
`
`(46) to the terminal (40). In Figure 3b a dedicated terminal (50) has a slot (52) to receive the
`
`12
`

`.torage means, adisplay (54) and controls (56). Coins canbe inserted into theterminal at
`
`(58) and notes at (60) to charge the data storage means with cash.
`
`Referring now to Figure 4a, this illustrates the logical connections and data flowbetween data
`processing systems involved in payment validation, and data download to storage means (30).
`A user connects the data storage means (30) to terminal (40) and logs on to a data web page 0f
`
`data access service provider (60). Either terminal (40 ) or service provider (60) then
`communicates via data paths (62) with payment validation authority (70) to check and
`authorise the user’s or payer’s payment. In the case of electronic cash the terminal (40) may

`
`.
`
`The service provider may provide a direct portal to data suppliers (80) or may collect
`information from data suppliers (80) and provide a “front end” to present data from the
`suppliers to the terminal user. Alternatively service provider (60) may regulate direct access
`between terminal (40) and data suppliers (80), as shown by links (66), by communicating with
`the terminal and the data suppliers to provide communication regulation information to, for
`example, instruct data suppliers about what information the user ofterminal (40) should have
`access to.
`
`In a preferred embodiment service provider (60) pays royalties at an agreed rate - for example,
`10 pence per track or 10 pence per minute - to an appropriate organ of the recording industry
`and the user of terminal (40) effectively pays the service provider. Billing can also be
`
