Description

POCKET DIGITAL WIRELESS DEVICE FOR THE PERSONAL INFORMATION MANAGEMENT AND FOR THE AUTHENTICATION OF THE COMMUNICATION AND THE INFORMATION EXCHANGE WITH OTHER DIGITAL DEVICES
The present invention refers to a pocket digital wireless device for the personal information management and for the authentication of the communication and the information exchange with other digital devices in Personal Area Network environment, enabling and allowing the personal security, the communication and the information exchange for multitasking activities. One of the most significant recent developments in wireless teclinologies is the emergence of wireless personal area networking, known as WPAN. Developed at the end of the 20th century, WPAN is based on a new technology called bluetooth, which uses short-range radio frequencies to transmit both voice and data. This cable-replacement technology wirelessly and transparently synchronizes data across devices and creates access to networks and internet within a range often meters. The bluetooth specification is ideal for mobile professionals who need to link notebooks, computers, mobile phones, PDAs, PUvfs, digital cameras, and other handheld devices to do business at home, on the road, or in the office. These technologies, ideal substrate to anywhere protected access to information and electronic transactions, use a worldwide coverage radiof equence band, enabling an easy information exchange between devices, indipendently from the access point, with low-cost and with an user friendly interface. Wireless personal area networking completes the spectrum of wireless connectivity, extending from home and small office settings to campus-wide local area networks (LAN) and wide area networks (WAN) connected via cell phone towers. Regarding bluetooth specification and features, bluetootli is a global specification for a small foπn-factor, low-cost radio solution providing links and integration between mobile computers, mobile phones, and other portable handheld devices, as well as connectivity to the Internet. It was developed by the Bluetooth Special Interest Group
(BSIG), established in 1998. The Group's intent is to form a de facto standard for the bluetooth air interface and the controlling software. Bluetooth radios operate in the unlicensed Industrial Scientific Medical (ISM) band at 2.4 GHz (range 2400 - 2483.5) and employ frequency-hopping (FH) spread spectrum technology to reduce interference and fading. A Time-Division Duplex (TDD) scheme is used for full-duplex transmission. Bluetootli' s main strength is its ability to simultaneously handle both data and voice transmissions. A mobile computer equipped with Bluetootli technology, for example, could link to a similarly equipped mobile phone to connect to the Internet, to receive or to send phone calls, to send SMS/MMS messages, to syncronize PLM data with the device. The bluetooth WPAN consists of up to eight active devices, with one hub and up to seven client devices. A bluetootli WPAN is capable of supporting an asynchronous data link with each client and synchronous voice links with up to three client devices. It provides a range of up to 10m at a transmit power of 1 mwatt. The range can be extended to 100m if the transmit power is increased to 100 mwatt. Bluetooth has a data rate of 1 Mbps. Bluetootli is designed to be low cost - eventually under 10 USD per unit. Concerning bluetooth network topology multiple bluetootli units form a Wireless Personal Area Network, called a piconet. A piconet consists of one hub device and up to seven client devices. It is possible to support more devices in a piconet by placing one or more of the clients into what is referred to as park "mode". In order to exchange information with the parked client, the hub must take it out of parked mode and return it to active mode. Only seven clients can be in active mode at any given time. When two piconets are in close proximity, they have overlapping coverage areas, a scenario referred to as a scatternet. Clients in one piconet can participate in another piconet as either a hub or client. This is accomplished through time division on multiplexing. In a scatternet, the two or more piconets are not synchronized in either time or frequency. It is to be noted, however, that a bluetootli device can only be a hub in one piconet, since tlie piconet is defined by the hub's bluetootli address. Each of tlie piconets operates in its own frequency- hopping channel, while any devices in multiple piconets participate at tlie appropriate time via tune division multiplexing. In the Personal Networking Hardware, tlie Radio
Frequency channels used for Bluetooth are from 2402 to 2480
MHz, with a channel spacing of 1 MHz. The Bluetootli radio hops from channel to channel at 1600 hops per second, wliich means every 625 ms. Each piconet has a unique hopping sequence, wliich is determined using an algorithm based on tl e address of the
Bluetooth hub. All Bluetooth units in tlie piconet are synchronized to this hopping sequence. Bluetootli radio modules use Gaussian Frequency Shift Keying (GFSK) for modulation.
The data is transmitted at a data rate of 1 Mb/second. The Bluetootli Baseband Layer. The baseband layer performs functions like Bluetooth packet assembly, forward error correction (FEC), automatic repeat request (ARQ), data whitening, Bluetooth clock synchronization, and frequency hopping control. The Bluetooth Link Manager Layer forms tlie piconet by inquiring what other Bluetooth radios are in tl e area, establishing connection and mamtaining tlie piconet. Tlie Bluetooth Link
Manager also handles security issues like authentication and encryption. Bluetooth provides for three low power modes to conserve battery life: sniff mode, hold mode, and park mode. While in tlie sniff mode, a device listens to the piconet at a reduced rate. The sniff interval is programmable, providing flexibility for different applications. In hold mode, only an internal timer is running, and data transfer restarts when units transition out of tlie hold mode. Park mode is used to handle more than seven cliente, since only seven clients can be "active" at any time, one client can be "parked" and anotlier one activated. In tlie park mode, tl e device's clock continues to run and remains synchronized to the hub, but tlie device does not participate in any way. Concerning tlie Privacy and tl e Infomation Security, tl e emerging electronic markets require secure partner identification for trading on open communication networks like the Internet. The tools and methods consist of cryptographic algorithms which were invented in the seventies. The methods are well known and international standards have been developed. In a few years most companies and many people will use a Digital Identity Card offering a wide range of secure Internet applications. Services and products provided by suppliers on the Internet today usually require password systems and credit card numbers. By using Digital Identity Cards tlie communication partners are securely identified by presenting their card electronically, passwords, PIN, etc. Thus, existing Electronic Commerce services can be enhanced and new ones, wliich require more security can be introduced. A Digital Identity Card is actually a smart card with a computer chip. The user inserts the card via a card-reader linked to tlie computer to access his private key (only accessible by himself) when he wants to open a transaction/communication session. The smart card also contains a certificate wliich verifies the identity of the owner when he or she communicates with partners. This certificate is sent to tlie partner together with the signed document. By tins certificate tlie addressee can verify the digital signature on the document and tlie identity of tlie partner. Thus the digital signature fullfils tl e following requirements: - the recipient of tlie document can make sure that the sender is really the person he supports to be; - tl e integrity of the document can be checked by tlie recipient; - tlie sender can never deny having sent tlie document; - the transaction/commumcation process can be successfully checked. The device according tlie present invention has on board a Digital Identity Card medium able to identify univocally throughout biometric teclinologies tlie owner, opening in a protected mode the access, tlie communication and the fruition of a service or tlie functions and applications of a linked device in tlie neighbourhood. Moreover, in the last years, tl e major handset suppliers began incorporating more functionality into their high-end handset models with what we call tlie "all in one" design approach. The trend was to put on board of these devices a built- in camera, Personal Information Management (PLM) applications, larger color screens and special keyboard. Such handsets support and incorporate some application development platforms. The tendency is that to design and manifacture devices able to do anything, in spite of the great size and tlie high cost, too complicate to use and manage. The purpose of tl e present invention is that to realize a wireless self powered device equipped inside with a SLM Card for tlie mobile communication, a Smart Id Card for tlie authentication and secure protected access, a Bluetooth chip, a processor and a storage area for tlie software (Operating System, PLM, SYNC) and tl e data storage functions. Whether you're in the office or on the road, you can now enjoy a whole new level of freedom and hassle-free connection to personal, corporate and public data. The device give to tlie users, in any bluetooth enabled area, tlie ability to connect and synchronize wirelessly with corporate and personal data, and Internet-based content. The device sniffs and discovers tlie presence of access points, personal computers, mobile phones, PDA and any other Bluetooth enabled device with wliich it is authorized to connect. The connection will be carried out as through a very fast modem, but wirelessly. The embedded applications can be used, after tlie personal identity authentication phase, to access and browse Internet ed Intranet information content, to check and send messages and e-mails, to syncronize and exchange data with desktops, PDA directly or through a corporate LAN. The built-in radio has an enhanced receiver, maximizing wireless range, and the device is a Bluetootli one to maximize compatibility and interoperability witli other products and devices. The connection is cable-free and since Bluetooth does not require a line of sight connection, all tlie devices can be in tlie pocket or briefcase, tlie user no longer have to juggle with multiple devices to get connected. This device, moreover, through its features, wirelessly coupled witli a bluetootli enabled mobile phone in tl e neighbourhood, has tlie capability to enable tlie mobile to use tlie internal SLM card of device, with tlie optimization and automatic management of the mobile to utilize more than one network provider SLM cards, so to reduce significantly tlie phone rates and to setup personal criteria and profiles of selection of the SLM cards (one plugged in the mobile phone and the other on the device of tlie present invention). The invention presents itself as a wireless portable secure bridge of personal network communication, clearly and easily authenticated. The device in its basic configuration includes a Bluetootli chip, a SLM Card, a Smart LD Card, and also a CPU, enougli memory for O.S. and SW, witli a biometric circuit to identify tl e owner. The invention has tlie purpose to offer an alternate and innovative distributed solution to heavy and expensive PDA or handsets. A single, pocket, thiny and personal device which actively interacts wiressly with tlie several digital devices in the neighbourhood, with a plurality of functions and tasks, with a very low cost in respect of traditional devices. The present device comunicates worldwide anyway anywhere acting as hub and gateway in a easy and user friendly mode. Several and rilevant are tlie advantages of tlie invention:
- faster time to market for new wireless devices designed and maifactured for a single and original function;
- low cost of the devices in respect to tlie current situation, characterised in higher costs for tlie interaction of several functions and hardware integration problems in a stand alone device; - benefits to tlie mobile operators, freed to dedicate tlieirselves to the service and to their quality/performance;

The device according tlie present invention act as a Wireless Digital Identity & Communicatio Module, working as a bridge between mobile phones, PDA, Digital cameras, MP3 Players, Notebooks, PCs and all the Bluetooth and Wi-Fi enabled devices who partecipate to tlie next generation information and communication technology's revolution. The access and communication device interface with tlie claimed device N is separated from tlie standalone devices and assigned to a unique mobile gateway. All tl e piconet devices can comunicate with tlie device N via Bluetooth and through it witli other devices. This layout and methodology will greatly low tlie related costs of tlie single peripherals and shorten tlie time to market of tlie new devices, with clear benefits to tlie mobile operators and full advantages to tl e user/owner of tlie device N to access for tlie communications to more than one service provider in a sure and protected way, widening the diffusion of e-mobile and e-commerce through authentication processes. Since the device N includes on board one or more SLM card, tlie mobile network operators can directly offer tlie device N to tlie user with their services without busying theirselves with tlie expensive promotion of specific manifacturer products. Until now tlie major handset suppliers are working to incorporate more ftmtionality into high-end handset models ' according tlie "All in One" approach with a much higher price, extra size and weight device; but separating tl e functions and tlie parts, these can be designed and manifactured witli an higher functionality and specific quality, these parts can be very inexpensive witli a good design and tailored to perform specific and dedicated applications and task, easy to use and extremely small, such to fit the user needs, to respect and help peoples in their daily life. Only tlie device N takes tlie charge of tlie use/activation of the oilier cooperative and linked devices granting tlie access and tlie digital security. The network service providers (electronic transactions, user identification, content providing) so freed can fully devote tlieir attention to their core business offering more quality and performance in a more competitive and flexible framework. The health of tlie users can be, therefore, granted by very low radiation emission and lower energy consumption systems. These specifications can be accomplished only by these last wireless teclinologies. Fig.l and Fig.2 show tl e following specifications of the device:
- a small sized case 1 such to allow tlie insertion of a. Smart Id Card;
