Abstract

A method of providing information, the method comprising interrogating a memory tag; receiving content from the memory tag by wireless electromagnetic communication in response to the interrogation, the memory tag comprising a memory and a transponder to enable the wireless electromagnetic communication; storing the content; sending a release request to an authorizer; receiving a release confirmation from the authorizer in response to the release request; and releasing the stored content in response to receipt of the release confirmation. The memory tag may contain encrypted content. A plurality of said release requests may be sent, each release request having an associated cost. An aggregate cost can then be calculated in accordance with the sum of the associated costs.

Claims

1. A method of providing information, the method comprising interrogating a memory tag;

receiving encrypted content from the memory tag by wireless electromagnetic communication in response to the interrogation, the memory tag comprising a memory and a transponder to enable the wireless electromagnetic communication;

storing the content;

sending a release request to an authoriser;

receiving a release confirmation from the authoriser in response to the release request; and

releasing the stored content in response to receipt of the release confirmation, comprising decrypting the stored content using a decryption key.

2. A method according to claim 1 wherein the step of releasing the stored content comprises outputting the stored content to a user interface.

3. A method according to claim 1 further comprising receiving a summary of the content from the memory tag by wireless electromagnetic communication, and outputting the summary to a user.

4. A method according to claim 1 further comprising receiving an authoriser address from the memory tag by wireless electromagnetic communication, and sending the release request to the authoriser address.

5. A method according to claim 1 further comprising receiving a cost indication from the memory tag by wireless communication, and outputting the cost indication to a user.

6. A method according to claim 1 wherein said release request is sent as a Short Message Service (SMS) message.

7. A method according to claim 1 wherein said release confirmation is received as a Short Message Service (SMS) message.

12. The method of claim 1, wherein the acts of interrogating, receiving encrypted content, sending the release request, receiving the release confirmation and releasing the encrypted stored content are performed in a radio frequency identification reader.

8. A method of enabling a release of stored content, the method comprising receiving a release request from a client;

and sending a release confirmation to the client in response to the release request, the release confirmation enabling a decryption key to be applied to encrypted stored content received from a memory tag by wireless communication to decrypt the stored content to release the stored content, the memory tag comprising a memory and a transponder to enable the wireless communication.

9. A method according to claim 8 further comprising receiving a plurality of said release requests from said client, each release request having an associated cost;

sending a plurality of said release confirmations to said client, each release confirmation being sent in response to a respective release request;

summing the associated costs to generate an aggregate cost; and

outputting the aggregate cost.

13. The method of claim 8, wherein acts of interrogating, receiving encrypted content, sending the release request, receiving the release confirmation and releasing the encrypted stored content are performed in a radio frequency identification reader.

10. Apparatus for providing information, the apparatus comprising a reader adapted to interrogate a memory tag and receive encrypted content from the memory tag by wireless electromagnetic communication in response to the interrogation, the memory tag comprising a memory and a transponder to enable the wireless electromagnetic communication;

a store for storing the content;

means for sending a release request to an authoriser;

means for receiving a release confirmation from the authoriser which is responsive to the release request; and

means for decrypting the stored content with a decryption key to release the stored content in response to receipt of the release confirmation.

11. An apparatus comprising:

a memory; and

a reader adapted to;

interrogate a memory tag and receive encrypted content from the memory tag by wireless electromagnetic communication in response to the interrogation;

store the encrypted content in the memory;

communicate a release request to an authoriser;

receive a release confirmation from the authoriser responsive to the release request; and

decrypt the encrypted stored content using a decryption key in response to receipt of the release confirmation.
