Definitions

  • the present invention relates generally to electronically aided exchange of information between social and business contacts using controlled access technologies, and more particularly, to the use of token authentication to control access to protected information in a contact's profile.
  • on-line dating and social networking constitute internet-facilitated modalities for meeting persons particularly in social engagements.
  • users fill out profile information that is stored in a central database. Those profiles are associated with other users in an internodal network arrangement where each user is linked to one or more third-parties through another user with which they have a pre-existing personal or business relationship. Users employ various search criteria to identify a subset of other users whom they may be interested in meeting and are allowed to contact or view the profiles of other users.
  • U.S. Patent Application 20050174975 deals with a wireless communication methodology wherein real world contact coincides with cyber world contact whereby a user may access information about a specific unknown person in their general location in order to decide whether potential compatibilities (either business or personal) may exist between them.
  • a methodology is described whereby a user broadcasts a search for compatible social or business interests in their general physical vicinity, receives and electronically reviews information about a potential contact within his/her vicinity and initiates contact by sending the user's profile back to the potential contact, whereupon it is hoped that real world contact will then ensue.
  • the drawback to this system is that the user spends their time broadcasting and sifting through a myriad of online social protocols, using intelligent devices having image and data display capabilities rather than spending valuable time making the far more profitable flesh to flesh contact.
  • Authentication tokens have been used to promote relatively quick access to secured data and other resources.
  • Physical tokens include objects that are read by an access control device to determine whether a user presenting the token should be given access. As the token holder approaches or otherwise submits the token, the access control device interrogates the token to make the determination.
  • tokens routinely incorporate cryptographic mechanisms for authentication. Encrypted codes are commonly stored within token memory for eventual decryption by the access device. To this end, tokens additionally rely on dedicated processors and/or memory for use during authentication. Though not necessarily used for authentication, tokens additionally include a set of generally unalterable data that is set by manufacturers. Such data includes serial numbers, manufacturer identifier data, time of manufacture, and/or other manufacturer controlled information used for inventory, quality control and other accounting purposes.
  • Bilateral, per transaction, exchange of electronic or digital tokens between persons (natural, business or premises) desiring to further their contact will provide some measure of convenience and security in accessing each other's secured profile in a virtual environment and afford the persons opportunity to further their contact in a real world if mutuality exists.
  • Embodiments of the present invention include a wireless device and a per transaction token based system for business and social networking by natural persons or businesses, in which actual contact precedes bilateral (or one way) exchange of tokens for after-contact, computer network facilitated access to each other's user profile, which may include user-defined data, to be followed, optionally by further exchange of private data.
  • Private data refers to any information, such as profile identification, phone number, Internet address, contact information, financial information, or medical information, which may allow perpetuation of that contact outside the virtual token-enabled environment.
  • per transaction token is taken to mean that the token is a disposable, single-use token.
  • the token may be of finite use rather than a single use, wherein the token may be set to expire over time or may be set to expire after a defined incremental use.
  • the present invention includes a wireless face-to-face, bilateral communication method comprising a one-to-one exchange of transaction tokens between at least one sending party and at least one receiving party who are both registered users of a service provider.
  • device refers to any wireless electronic token device of the present invention. Where carried by a natural person, said device may be any portable electronic device that is capable of transmitting and/or receiving transaction tokens.
  • a token device may be stationary, preferably desktop device, which can communicate with an individual's portable device.
  • the information exchange transmission may be an intended transmission without the need for face-to-face proximity of one or more previously unknown or unconnected parties.
  • client a service provider's subscriber, provides credentials (e.g., username and password) for tokens to be preloaded to client's device.
  • credentials e.g., username and password
  • the service provider issues to the client a plurality of digital transaction tokens.
  • Each digital transaction token may be configured to provide proof of the client's authorization for a social or business contact or to a business premise, such as an event organizer, club house, and/or hospital, to access the corresponding client's profile.
  • the plurality of transaction tokens may include an authentication token that is configured to provide proof of identity at the service provider's portal and which may be provided by the client to the service provider to obtain additional transaction tokens without requiring the client to resubmit credentials.
  • An application on a client device receives and loads the transaction tokens.
  • a network server generates the transaction tokens and provides the tokens to a client's device.
  • the transaction token may be provided by the server as part of the code comprising a profile page.
  • the authentication module authenticates the client's token and returns to the requestor client, a user reply, at the option of the requestee, in the form of a profile of requestee client.
  • the authentication module verifies that the token is being submitted by a valid user; that the received token being submitted belongs to a valid requestee and that the token is still valid, etc—and then with permission of the requestee discloses the requestee's profile to whatever granular detail desired by the requestee.
  • the authentication module may watch for the other part of the transaction pair, i.e., the user submitting the token, should also have the mirror of the other user submitting his/her token to start the reciprocal to the transaction.
  • the token exchange Upon encountering a potential social or business contact, exchange of transaction token takes place between the service clients.
  • the token exchange is at least a two-way exchange; however, the token exchange may be one way only, i.e., one client offers his/her token to another client, while the other client does not reciprocate with his/her token.
  • the token device application may send a profile request to a service provider's network server.
  • the profile request may include the transaction token optionally embedded in the profile page code of the requesting client rather than delivering the token separately.
  • the server receives the profile request, determines whether the associated token is valid, and processes the request and informs the other party that a reply profile is needed.
  • the exchange between users is accomplished with only click or button activation.
  • the transaction token is embedded in profile page code provided in a profile response.
  • the transaction token is loaded by the browser as well.
  • the transaction token is optionally maintained in the code of the profile page rather than delivered separately.
  • the browser application may generate a profile request in response to receiving further user input. The browser application then includes the authentication token from the profile page code in the subsequent profile request.
  • the client-subscriber or user uploads these tokens to a data server computer system using any suitable means of data communication such as cradles, Bluetooth, or WiFi.
  • uploading to an Internet-connected computer is done via a universal serial bus (USB) interface on the wireless device
  • uploading may be done via a wireless communication to the Internet.
  • USB universal serial bus
  • the tokens stored in a receiver's wired or wireless token device may be uploaded to a central service which may include a website, a database and one or many servers.
  • a central service which may include a website, a database and one or many servers.
  • the user who has uploaded the tokens to the data server logs into a world wide web-interface that allows them to classify their received profiles according to type, group, interest, and/or some other classification. Since the received profile(s) belongs to another registered user of the system, a picture and other general information, excluding private data, may be available to refresh the user's memory of the networking encounter and to determine what the levels of interaction should be.
  • users may have the ability to determine the granulation of their profile that may be seen by other users, and to set the available channels for future communication, e.g., instant message, email, video teleconference (VTC), phone, gaming, collaboration and/or voicemail, or none at all.
  • VTC video teleconference
  • Alternate embodiments include the cases where: 1) user's device communicates with the server via a cable, cradle, or other physical connection to a PC or other electronic apparatus which can relay tokens or other information to the server; or 2) through any form of wireless connection, such as Bluetooth Wi-Fi or 802.11, which may relay the tokens or other information either directly or through some intermediary (e.g., a cellular network or PC) to the server.

  • the algorithm for creating a unique code on-the-fly reduces, preferably eliminates, the need for any user to exchange his/her actual ID code with another user.
  • the actual IDs of the respective users may be deleted from the token devices and replaced with the new shared code. In this way, each user's code is not being stored on other user's token devices, thereby providing another level of anonymity.

For example, certain users may be planning to attend the same concert, conference, tradeshow, and so on. Prior to the event, the users may, for example, access the event sponsor's website and download the tokens of the other attendees, albeit without specific information. Upon physically meeting at the event, the users may verify (i.e. through token exchange) each other's identity.
  • the order of operations is modified, instead of (1) meeting in person, followed by (2) exchanging tokens, and followed by (3) exchanging user profiles at their personal computer, the order of operations may be (1) exchanging tokens, followed by (2) meeting in person, and followed by (3) exchanging user profiles at their personal computer.
  • the pre-acquired tokens may be locked, and upon meeting at the event, the tokens may be unlocked.
  • the event sponsor or service provider has the user profiles, which are initially locked, and upon meeting the users verify identity and then may return to their personal computer and use the token to unlock the user profiles of interest.
  • the device identifications are associated with a second encryption key, instead of associated directly with the user's information.
  • an intermediary encryption key such as the well-known public key infrastructure (PKI), may be utilized.
  • PKI public key infrastructure
  • two or more devices exchange small data files that contain the actual profile information, which may be encrypted.
  • the profile information may be stored in memory on the individual devices and the service provider website may be used to provide the key to “unlocking” the received information following an exchange.
  • profile data is exchanged between two or more users. Subsequently, each user accesses the service provider website in order to unlock the exchange.
  • additional security may be provided in that it may not be required that complete profile information of all user-subscribers be stored on a central server, which is potentially vulnerable to security threats.
  • This embodiment of the invention may reduce and/or substantially eliminate the need to formally register with the service provider by providing complete user profile information, because all personal profile information is managed locally not centrally.
  • this embodiment of the invention may allow each user to control his/her outgoing profile information, such as to provide one-time profile information and/or provide perpetual profile updates.
  • each user may have multiple levels of control, such as to (1) turn on and off the ability of another user to access my his/her profile, (2) turn on and off the ability of another user to receive automatic profile update information, and (3) determine the granulation of their profile that may be seen by other users (e.g., provide a certain email address, physical address, and/or phone number only).
  • QR Quick Response
  • a QR code is a matrix code (or two-dimensional bar code) created in Japan that allows its contents to be decoded at high speed. QR codes that store addresses and URLs may appear, for example, in magazines, on signs, buses, and business cards.
  • user-subscribers may have a QR code on any of their respective physical devices, such as on the surface of a cell phone, PDA, business card, keychain, and so on.
  • the QR code may be used as the mechanism to provide unique wireless electronic device identification. Any user that has, for example, a camera phone that is equipped with the correct reader software may scan the image of the QR code of another user, which, in the context of the invention, may be used for verifying user identity. More specifically, stored on the database of the authentication server are the QR codes of the user-subscribers.
