BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows an example of a system within which the present invention could be implemented; and
Figure 2 is a flowchart illustrating the steps of the present Invention. DESCRlPTtON OF PREFERRED EMBODIMENTS
Referring to Figure 1, messages are sent to a communications device 10 over a communications network 12.
In the illustrated example embodiment, the communications network is a mobile communications network and the communications device 10 is a mobile telephone.
However, it will be appreciated that while the communication device 10 is illustrated as a mobile telephone, this device could be any other communication device which is able to communicate via the mobile communication network. Some examples of such devices are personal digital assistants (PDA's) and computers.
Messages are typically sent over the communications network 12 using a Short Message Service (SMS) protocol. However, other protocols may be used such as Multimedia Message Service (MMS), for example.
The sending and receiving of messages is controlled by a Short Message Service Centre (SMSC) 14.
It will be appreciated that when an intended recipient receives, via communications device 10, an SMS, they are not always able to ascertain if the SMS originates from an authentic source or not.
For example, they may not know the full number of the sender of the SMS. Alternatively, a fraudster may send a fraudulent SMS notification and "spoof the number so that it looks like a valid number.
This poses particular difficulty where the SMS is a notification of a transaction such as a financial transaction. In one example embodiment a server 18, typically a server of a financial institution, is connected to the SMSC 14 via another network 16. Tha server 18 has an associated memory 20 typically In the form of a database.
At least one code is. stored in the database 20 where the at least one code is associated with an intended recipient of a message and wherein the at least one code is known to the intended recipient.
Preferably, a plurality of codes are stored in the database 20 wherein each of the codes is associated with an intended recipient.
The code may be a random and unique code generated for the intended recipient by the server 18 and transmitted to the intended recipient over the communications network 12.
Alternatively, the code may be received from the recipient via the communications network 12 and stored in the database 20.
The code will typically be an alphanumeric code.
In order to authenticate a message transmitted to an intended recipient, the intended recipient of the message is identified using an identification of the mobile device of the intended recipient such as the Mobile Station Integrated Services Digital Network (MSISDN) of the intended recipient.
The database 20 is then accessed and the code associated with the intended recipient Is extracted.
This code is then transmuted, typically over the communications network 12, to the intended recipient who can then use the code to authenticate the message.
In one embodiment, the code is transmitted together with the message which is to be authenticated. It will be appreciated that the method of authentication could be used in various applications.
The application discussed above is with respect to a financial institution who wishes to send verification messages regarding transactions a user may have effected on an account with the financial institution.
Thus, a user paying an account may receive a verification message that the payment has been successfuFiy processed.
This verification message could be authenticated in the manner described above with the code being transmitted together with the message.
In another example application, a user of another communications device 22 who wishes to transmit a message to a user of the first communications device 10 may have the message authenticated.
In this embodiment, the message is received by the SMSC 14 which then communicates with the server 18 to identify the message recipient and to attach the code from the database to the message sent to the intended recipient.
It will be appreciated that the methodology described above is Implemented by the server including at least one processor to implement the various steps. Although the illustrated embodiment shows a single server, it should also be appreciated that there could be a plurality of processors spread across a plurality of servers in order to implement the methodologies.
Executing on the at least one processor is typically machine-readable medium on which is stored one or more sets of instructions (e.g., software) embodying any one or more of the methodologies or functions described herein. The software may also reside, completely or at least partially, within a main memory of the server and/or within a processor during execution thereof by the computer system.
While the machine-readable medium is typically a single medium, the term "machine-readable medium" should be taken to include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) that store the one or more sets of instructions. The term "machine-readable medium" shall also be taken to include any medium that Is capable of storing, encoding or carrying a set of instructions for execution by the machine and that cause the machine to perform any one or more of the methodologies. The term "machine- readable medium" shall accordingly be taken to Include, but not be limited to, solid-state memories, optical and magnetic media, and carrier wave signals.
It will be further appreciated that although the present invention has been described with servers 14 and 18 operating remotely from one another, the present invention can also be implemented directly on server 14 with a separate module which is used to execute the authentication functions.
