Abstract: A method of payment using tokens issued by a third party comprising the steps of: a. A transaction management unit receives a request to perform a service for which payment with tokens is required; b. The management unit checks whether there are yet unused tokens available; If an unused token was found, go to step (c); If there are no available tokens, then indicate that, then END; c. The management unit requests information on an available token from a database. The status of the used token is changed to “used”; d. During the subsequent transaction, the management unit sends information relating to the token now used. A system for managing and monitoring the use of tokens, comprising: a. a transactions management unit using tokens, wherein the unit is activated when a local user requires to perform a service for which payment using tokens is required; b. a tokens database which includes information on tokens acquired from the third party; c.

Abstract: A method for collecting payment over a distributed digital computerized communication environment by a third party for services using digital tokens issued by a third party. The services may be provided by the third party or another party. The tokens are acquired by the user and stored in its database. The user cancels the tokens itself as it uses the provided services. The second party can monitor and report on the cancellation of tokens by the user. Fraud is reduced or eliminated by providing an open system that permits other parties to observe the user's cancellation of its tokens.

Abstract: A system for handling permits, comprising means for reading a certificate, means for reading a permit and decision means for performing a predefined activity based on the results of the combined verification of the certificate and the permit. A method for handling permits, comprising the steps of (A) Approval of the issuance of a permit to a specific person, after that person was identified and following some decision routine; (B) The generation by the authorities involved of a message for a permit, which includes data items to indicate the identity of the permit issuing authority, the identity of the person to whom the permit was issued, the type of permit and to whom it is to be presented; (C) Encryption of the message by an authorized person to generate the permit, with the encryption using their private key; and (D) the permit is delivered to the person who has been identified with his/her certificate.

Abstract: Disclosed is a method for safe distribution of encryption keys including a known public and secret private keys in establishing a secure link between computer users resided at separate location whom have no previous secure communications. The secure communication link occasionally and anonymously interrogates the key distribution center for the certificate pertaining to the computer users in ensuring the validity and integrity of the information stored in the center which is not tampered by any unauthorized persons. The interactively interrogating of the key distribution center is conducted via a trusted and verified certificate decision making process which encompasses the acknowledging to user who receives a valid certificate, accepting an encrypted message, key distributed center's answer to the correct up-to-date certificate, decrypting the key distributed answer via the public key, and matching the answer's identification.
