Claims32
A playing card system configured to authenticate a playing card for playing a card game, the playing card system comprising a playing card, a playing card authentication device, and a playing card authentication server, wherein the playing card comprises
- an electronic memory storing authentication data,
- an antenna configured for wireless communication,
- a processing circuit configured to
- wirelessly receive a digital command over the antenna from the electronic playing card authentication device,
- create an authentication token in response to receiving an authentication command, the creating comprising reading the authentication data from the memory and applying a cryptographic function thereto,
- wirelessly transmit the authentication token to the device through the antenna, the playing card authentication device is configured for verifying the authenticity of the playing card, the playing card authentication device comprises
- a communication unit configured to communicate over a computer network to the playing card authentication server,
- an antenna configured for wireless communication with the playing card,
- a processing circuit configured to
- wirelessly send a digital authentication command over the antenna to the playing card,
- receive from the playing card an authentication token in response to the digital authentication command,
- send the authentication token to the authentication server through the communication unit, and
- receive from the authentication server information on the authenticity of the playing card,
- the playing card authentication server is configured for verifying the authenticity of the playing card, the playing card authentication server comprises
- an electronic memory for storing authentication data,
- a communication unit configured to communicate over the computer network with the playing card authentication device,
- a processing circuit configured to
- receive from the playing card authentication device the authentication token,
- verify the authentication token with the authentication data stored in the memory of the playing card authentication server, and
- if said verification succeeded, sending information indicating the authenticity to the playing card authentication device.
A playing card configured for playing a card game, said playing card comprising:
- an electronic memory storing authentication data,
- an antenna configured for wireless communication,
- a processing circuit configured to
- wirelessly receive a digital command over the antenna from an electronic playing card authentication device,
- create an authentication token in response to receiving an authentication command, the creating comprising reading the authentication data from the memory and applying a cryptographic function thereto, and
- wirelessly transmit the authentication token to the device through the antenna.
A playing card authentication device for verifying the authenticity of the playing card, the playing card authentication device comprising:
- a communication unit configured to communicate over a computer network to a playing card authentication server,
- an antenna configured for wireless communication with the playing card,
- a processing circuit configured to
- wirelessly send a digital authentication command over the antenna to the playing card,
- receive from the playing card an authentication token in response to the digital authentication command,
- send the authentication token to the authentication server through the communication unit, and
- receive from the authentication server information on the authenticity of the playing card.
A playing card authentication server for verifying the authenticity of a playing card, the playing card authentication server comprising:
- an electronic memory for storing authentication data,
- a communication unit configured to communicate over a computer network with a playing card authentication device,
- a processing circuit configured to
- receive from the playing card authentication device an authentication token,
- verify the authentication token with the authentication data stored in the memory of the playing card authentication server, and
- if the verification succeeded, sending information indicating the authenticity to the playing card authentication device.
A playing card authentication method to authenticate an electronic playing card, the method comprising
- wirelessly sending a digital command over an antenna to the playing card authentication device to cause the playing card to create an authentication token, the playing card comprising an electronic memory storing authentication data, creating the authentication token comprises applying a cryptographic function to the authentication data,
- wirelessly receiving the authentication token from the device through the antenna,
- having the authentication token verified and authentication data stored in the memory of a playing card authentication server.
