Abstract

Preference data is received. The received preference data is compared to stored preference data associated with a user with which the received preference data is associated. A determination is made whether to authorize an action based at least on the comparison. The preference data is received as a selection.

Claims (18)

1. A method for utilizing a computer-readable tamper-evident log to manage an action to be performed by at least one computing device, the tamper-evident log accessible via at least one network interface that is communicatively coupled to a communications network, the method comprising:

before the action is allowed to be performed, appending information about the action to the tamper-evident log;

before the action is allowed to be performed, obtaining an attestation value associated with the action, the attestation value having been computed using a cryptographic digital signature function, the attestation value based at least in part on the information about the action; and

upon appending the information about the action to the tamper-evident log, performing the action;

wherein, tampering of the tamper-evident log is detectable by performing a verification using the information about the action and the attestation value for the action.

2. The method of claim 1 , further comprising, performing the action, the action comprising executing a script.

3. The method of claim 1 , further comprising, upon verifying the action in the tamper-evident log, performing the action.

4. The method of claim 1 , further comprising, computing the attestation value for the action.

5. The method of claim 1 , further comprising, performing an authentication of the tamper-evident log using the information about the action and the attestation value of the action.

6. The method of claim 1 , further comprising, authenticating the tamper-evident log using the information about the action and the attestation value of the action.

7. The method of claim 1 , further comprising, detecting tampering of the tamper-evident log.

8. The method of claim 1 , wherein, the attestation value was computed based, at least in part, on information that identifies a client.

9. The method of claim 1 , wherein, the attestation value was computed based, at least in part, on a time and date.

10. The method of claim 1 , wherein, the information about the action is associated with copyrighted material.

11. The method of claim 1 , wherein, the attestation value was computed based, at least in part, on a nonce.

12. The method of claim 1 , wherein, performing the action is associated with a state change being made.

13. The method of claim 1 , wherein, the action is a transaction.

14. The method of claim 1 , wherein, the action is an interaction.
