Portable system for updating transaction information on contactless chips

Abstract

A mobile system for transitional updating of information in contactless chips, wherein allowing the chip users to perform transactional operations when in transit, using a smartphone, tablet, notebook, smartwatch or any other device capable of run mobile applications, U includes a user request via mobile application; authentication on a network server; and authentication with an issuer key. It is an alternative for contactless chips users to perform transactional operations while in transit using a smartphone, tablet or any other device capable of running mobile applications. It allows the user complete autonomy in the process of updating or consulting the contents of their chip, eliminating their dependence on the network of fixed terminals.

Claims

1. A method for transitional updating of information in a chip of a mobile device using an operational network server comprising: receiving a request by a user through a mobile application running on the mobile device for a transactional operation; reading information from the chip in response to the request from the mobile application; encrypting transactional information read from the chip; transferring the encrypted transactional information remotely to the operational network server; performing an authentication on the operational network server; performing an authentication with a first issuer key; and updating information on the chip based upon a transactional response from the operational network server; wherein the mobile application is composed of a source code protected by a security layer to avoid reading by unauthorized third-parties.

2. The method according to claim 1 further comprising using multiple cryptographic keys together along the authentication steps.

3. The method according to claim 2 further comprising ensuring the integrity of the transactional information transferred remotely with a cryptographic model, reducing the possibility of fraud.

4. The method according to claim 2 further comprising using a second key that encrypts read and write keys associated with a serial number of the chip.

5. The method according to claim 3, wherein the cryptographic model reduces the possibility of fraud by insertion of a fraudulent agent between the mobile application and the server of the operational network.

6. The method according to claim 4, wherein the transactional information is transferred and interpreted by the operational network server using the second key; and wherein the serial number is provided by a sending agent.

7. A method for transitional updating of information in a chip of a mobile device using an operational network server comprising: receiving a request by a user through a mobile application running on the mobile device for a transactional operation; reading information from the chip in response to the request from the mobile application; generating a first encrypted key to ensure the integrity of transactional information read from the chip; encrypting the transactional information for remote transfer; transferring the encrypted transactional information remotely to the operational network server; by the operational network server, integrity testing for the transactional information; by the operational network server, performing an authentication with an issuer key of an issuing agent; by the operational network server, using a second encrypted key linked to the transaction to encrypt read and write keys associated with a chip serial number of the chip and provided by the issuing agent; by the operational network server, determining a transactional response; returning the transactional response to the mobile application running on the mobile device by the operational network server; and updating information on the chip based upon the transactional response from the operational network server; wherein the mobile application comprises a source code protected by a security layer to avoid reading by unauthorized technicians or potential fraudsters.

8. The method of claim 7, wherein integrity testing for the transactional information comprises using a cryptographic model, reducing the possibility of fraud by insertion of a fraudulent agent between the mobile application and the operational network server.

Description

(1) Therefore, in order to allow the best possible clarification of the object in question, a description will be given with reference to the following FIGURE, where:

(2) FIG. 1 illustrates a flow chart with the steps of the transactional process of updating and authenticating information between the contactless type chip and the operational network server;

(3) Accordingly, as shown in FIG. 1 above, the mobile system for transitional updating of information in contactless chips, object of this patent of invention, consists of a process composed of three macro steps, namely:

(4) User request via mobile application;

(5) Authentication on Operational Network Server;

(6) Authentication with the Issuer key;

(7) The transactional process starts with a request from the user through the mobile application for query or information recording. Approaching the chip and the mobile device, the information on that chip is read by the application and the transaction requested by the user is then processed and encrypted for remote transfer. The transactional information is then transferred and interpreted by the operational server using a second key that encrypts the chip read/write keys owned by the respective sending agent. The server then returns the transactional information to the application executed by the user's mobile device and updates the information on the chip, completing the transactional operation.

(8) It's been addressed in this Specification of a new design for the “MOBILE SYSTEM FOR TRANSITIONAL UPDATING OF INFORMATION IN CONTACTLESS CHIPS”, presenting, as can be evidenced by the description and FIGURES presented, some advantages and differentiated applications with respect to the existing conventional methods.

(9) Having thus been described and illustrated the best presently contemplated embodiment for the accomplishment of the present invention, numerous modifications and variations in its embodiment may be readily introduced by those skilled in the art. However, it is understood that the present invention is not limited to the practical aspects illustrated and described in this report, encompassing within its scope all obvious variations and modifications which may not be described.

(10) For the advantages it offers and still because it has truly innovative technical characteristics, it fulfills all the requirements of originality and novelty in the field, meeting the necessary conditions to obtain an Invention patent.
