When two parties of a cyberspace transaction register their identity attributes under a CITA system each party is assigned a unique, encrypted and digitally signed identity token. When the consuming party seeks access too, or payment for, cyberspace services, the providing party submits their identity token to the consuming party. The consuming party creates a request token, containing both the consumers' and the providers' identity tokens, and the transaction related information, to the CITA system. The CITA system validates the identity tokens and either creates a payment confirmation token by processing the payment request, or creates an access confirmation token by dynamically defining the minimal consumer identity attributes required to gain access to the provider's service. The confirmation token is encrypted and digitally signed and returned to the consumer, and then forwarded to the provider to complete the transaction without either party openly exchanging personal identity attributes.

Methods and systems for secure transmission of information are provided. In accordance with a method of the present invention, a client sends to a server, a request, at least one unique identifier and an encryption key. The server generates a reply to the request and identifies a mobile device (based on the at least one unique identifier) to which to send the reply. The server also encrypts the reply, using the encryption key, to thereby produce an encrypted reply. The encrypted reply is then sent from the server to the mobile device (e.g., a mobile phone). Once received by the mobile device, the encrypted reply is available for transfer (automatically or manually) from the mobile device to the client. Once provided to the client, the client can decrypt the encrypted reply using the encryption key. The decrypted reply is then available for use at (e.g., by) the client.

Access to digital data is controlled by encrypting the data in such a manner that, in a single digital data acquisition step, it can be decrypted only at a specified location, within a specific time frame, and with a secret key. Data encrypted in such a manner is said to be geo-encrypted. This geo-encryption process comprises a method in which plaintext data is first encrypted using a data encrypting key that is generated at the time of encryption. The data encrypting key is then encrypted (or locked) using a key encrypting key and information derived from the location of the intended receiver. The encrypted data encrypting key is then transmitted to the receiver along with the ciphertext data. The receiver both must be at the correct location and must have a copy of the corresponding key decrypting key in order to derive the location information and decrypt the data encrypting key. After the data encrypting key is decrypted (or unlocked), it is used to decrypt the ciphertext. If an attempt is made to decrypt the data encrypting key at an incorrect location or using an incorrect secret key, the decryption will fail. If the sender so elects, access to digital data also can be controlled by encrypting it in such a manner that it must traverse a specific route from the sender to the recipient in order to enable decryption of the data. Key management can be handled using either private-key or public-key cryptography. If private-key cryptography is used, the sender can manage the secret key decrypting keys required for decryption in a secure manner that is transparent to the recipient. As a consequence of its ability to manipulate the secret keys, the sender of encrypted data retains the ability to control access to its plaintext even after its initial transmission.
