Telecommunication method for securely exchanging data

Abstract

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.

Description

BACKGROUND OF THE DISCLOSURE[0001]1. Field of the Disclosure[0002]The invention relates to the exchange of data securely, in particular to the exchange of data using a digital cellular wireless communications network.[0003]2. Description of the Related Art[0004]An increasing number of people are exchanging sensitive data using telecommunication devices over digital cellular wireless communication networks. It is not safe to store this information on the telecommunications device its self, because it can be stolen. Likewise it is inconvenient for the user to always enter data into their telecommunications device when completing a transaction or using a secure website. These devices typically have touch screens, and it can be time consuming to enter the same data for similar transactions which are repeatedly performed.SUMMARY OF THE PRESENT DISCLOSURE[0005]The invention provides for a method and a server in the independent claims. Embodiments are given in the dependent claims.[0006]As...

Benefits of technology

[0027]In another embodiment the web service becomes inoperative after a predetermined duration. In this example the first server is able to retrieve the second unencrypted data only for a predetermined duration. After this the URL becomes inoperative and the first server can no longer retrieve the second unencrypted data. This provides more security that the second unencrypted data will not be stolen.
