Methods and systems for intelligent tracking and/or play and/or management of card gaming use an intelligent card distribution or holding device with detectors for determining the value and unique identity of individual cards and for recording card play. Playing cards are equipped with a read/write data storage connected to a transponder and/or incorporated into electromagnetic writable particles or smart particles (smart dust). A system of the invention records various game play events on the playing cards themselves during game play and optionally also in a database on the system. In specific embodiments, the principal scanning and writing elements and electronic and optical interfaces are embodied into a hand-held card holder (HHCH). In specific embodiments, the system utilizes various types of sensors and/or indicators and/or and electronic circuits and software to scan, track, monitor, compute, and interface with electronic devices, to enable the automatic operation of Casino table games. The system can scan playing cards, scan gaming chips, indicate a players win/loss/draw, increase or decrease player betting positions, compute awards to players based on their playing activity, photograph individual players, and transmit player's images to casino security/surveillance departments and or other authorized casino personnel. The system may activate table displays that indicate each player's win/loss/draw of their bets, and/or dealers card count, indicate in the game of blackjack when a dealer has blackjack, or any other significant event that occurs such as indicating when a player has a winning/loss/draw on specific card combinations.

Methods, devices and systems for moderating and policing voluntarily established transparency regarding past and present, and personal and professional relationships via online networking services. Identity of a person or commercial entity is verified before registration as a user. Each user is permitted a single profile. A profile includes a record of all relationships entered in the profile, some of which may be hidden by user. Each user is capable of linking his profile to profiles of other consenting users. Owner of a profile may flag inaccurate information on other linked profiles. The reliability or value of information in a profile is measured as a function of duration of existence of profile, transparency of the information in the profile, periods of inactivation, and number of times the profile is correctly flagged. A code is generated and used to allow gradual exposing of the profile of a user to his prospective contacts.

A wholesale and/or retail check out station system includes a biometric finger print reader and storage for reading and storing biometric data of employees having access to the cash registers of the check out stations in the system. Authorization to use a cash register in the system is programmed into the microprocessor in the system, limiting use of a cash register to authorized employees. Employees are identified by finger print using biometric technology. Limitations of use is extended to access to operate particular cash register(s); handling returned merchandise at a cash register; refunds on returned purchases require authorization of the manager and the cashier; cashing checks at a cash register, where the limitation includes only cashing of employer drawn payroll checks of employees; and, clearing errors made in tabulations at a cash register. Unauthorized persons attempting to gain access to cash registers to which they are not authorized serves to activate an alarm.

A method and system for tracking and providing an audit trail for off-line smart card transactions includes storing information representing a monetary transaction in a permanent memo on an smart card microprocessor and holding the transaction amount in escrow until the stored information is transmitted from the smart card, for example, at an on-line terminal, to a host on-line system for logging to a tracking system. The monetary transaction includes a transaction with an off-line device, such as another smart card. The escrowed transaction amount represents, for example, a load transaction to one of the smart cards and an unload transaction to other smart card. Once the memo is deleted from the respective smart cards, the load values of the respective smart cards are incremented or decremented by the transaction amount. Alternatively, the smart cards may be provided with a card-to-card key, in which case, a permanent memo is stored only on the receiving smart card.

The generation and management of decentralized identifiers of an entity. A decentralized identifier of a particular entity is recorded. Then, upon determining that the particular entity is granting a permission to another entity, the permission is signed based on the recorded decentralized identifier. As one example, the permission may be signed by a private key of the decentralized identifier. The permission may be verified upon request by authenticating the signed permission being associated with the recorded decentralized identifier; and authorizing the other entity to act upon the data depending on the authentication. As an example only, the authentication may occur using a public key associated with the recorded decentralized identifier.

The present invention provides a gaming system that can allow a game to be appropriately advanced even by an inexperienced dealer by way of navigating the dealer in game advancement, thereby allowing fraud to be avoided and cost to be reduced. An image input device, which captures images for displaying to players playing the game at a plurality of stations, captures an image of a side of a game portion on which the dealer is positioned to include card placement areas. Then, a controller performs image recognition processing of comparing image data of the card placement areas captured by the image input device with comparative image data stored in memory. Thereafter, in a case in which image recognition processing results in an image showing a card being included, the score of the card game is calculated based on recognition results of the images showing cards.

The present invention refers to a method for verifying the identity of a speaker based on the speaker's voice comprising the steps of: a) receiving a voice utterance; b) using biometric voice data to verify that the speakers voice corresponds to the speaker the identity of which is to be verified based on the received voice utterance; and c) verifying that the received voice utterance is not falsified, preferably after having verified the speakers voice; d) accepting the speaker's identity to be verified in case that both verification steps give a positive result and not accepting the speaker's identity to be verified if any of the verification steps give a negative result. The invention further refers to a corresponding computer readable medium and a computer.

Applications of the present invention are particularly useful in providing a system that allows the secure distribution of medical documents through a medical kiosk. The medical kiosk includes a customer interface and a camera that captures an image of the customer and attaches the image to a medical document.
