Patent attributes
The invention provides for a telecommunication method of securely exchanging unencrypted data between a telecommunications device and a first server computer system via a digital cellular wireless telecommunications network, wherein the telecommunications device is a battery powered mobile end user telecommunications device, wherein the method comprises the steps of: encrypting the unencrypted data using a first encryption algorithm into first encrypted data, sending the first encrypted data to a second server computer system via a first network connection of the digital cellular wireless telecommunications network, storing the first encrypted data by the second server computer system, sending an order request to the first server computer system via a second network connection of the digital cellular wireless telecommunications network by the telecommunications device, sending a data publishing request to the second server computer system, generating a cryptographic key pair, sending the first encrypted data, the public key, and the private key to the telecommunications device, decrypting the first encrypted data into the unencrypted data, encrypting the unencrypted data into second encrypted data using the public key, sending the second encrypted data to the second, generating a web service for providing the second encrypted data via an URL, sending the URL to the telecommunications device, sending the URL and the private key, requesting the second encrypted data from the second server computer system, sending the second encrypted data to the first server computer system by the second server computer system using the wired network connection, decrypting the second encrypted data by the first server computer system into the unencrypted data, and combining the order request with the unencrypted data.
