Description
WO 2005/115045 PCT/AU2005/000728 IDENTIFICATION SYSTEM AND METHOD Background of the invention The present invention relates to an identification system for authenticating a user. 5 Description of the Prior Art The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that that prior art forms part of the common general knowledge. 10 Whenever computers are used to perform various personal and commercial activities, secure access is a major area of concern in virtually all applications. A number of disaster stories exist related to "hackers" gaining unauthorised access to various computer systems, and therefore private and confidential data. 15 With the exponential growth of the Internet in recent years, the security problem has compounded due to a significant number of commercial services available to users. A major issue is that most users, who are not technically minded, do not understand the intricacies of communication protocols and network architectures, therefore leaving them 20 vulnerable to attacks from hackers. With the growing number of attacks and security breaches taking place on a regular basis, the existing Internet environment has significantly undermined any public confidence in the security of Internet access to private information such as banking activities. 25 Over the past few years, financial institutions have strategically focused on the Internet as a means of customer access to reduce their branch service costs. They have spent significant funds to upgrade their gateways and security software. This trend, coupled with continued significant publicised Internet security breaches within the current environment, 30 indicates that there continues to exist a very strong need for a cost effective process that WO 2005/115045 PCT/AU2005/000728 -2 can be implemented to facilitate a "hacker" proof communication link between institutions and their customers. Most solutions currently in place rely on user names/personal identification numbers and 5 passwords, however, these are not completely effective, because "hackers" continue to find ways through the use of elaborate techniques, such as "phantom cookies" and "keyloggers", to emulate software functionality and record keystroke entries. In the majority of applications, once the entry of a user name/personal identification 10 number and password is received and authenticated by the host system, complete access is granted, regardless of whether the person entering this information is the genuine customer or a "hacker" who has obtained the information through fraudulent means. Furthermore, in most cases, it is only when a customer discovers the existence of unknown transfers of funds that the fraud becomes evident. By then the damage has already been done. 15 The tools and schemes devised to date continue to rely upon sophisticated and costly processes that require downloaded software, or devices that generate keys that must be synchronised with a host system. Other behavioural and physical identification devices are also available such as signature recorders and verifiers, fingerprint recorders and verifiers, 20 and retinal recorders and verifiers. The above devices are extremely sophisticated, complex to set up, costly to maintain and upgrade, and require elaborate support software. Unless both recording and verification functions are set up at the individual PC level for these devices, they require transmission 25 of recordings for verification and therefore are also open to interception by hackers who can record and emulate identical transmissions. Only when institutions provide each customer with devices such as hand held electronic PIN/Password generators, can secure entry be ensured. However, establishing and 30 maintaining such devices is extremely costly to all concerned and can only be used on a WO 2005/115045 PCT/AU2005/000728 -3 one-on-one basis. Therefore, if a customer has accounts with multiple institutions that apply the same identifying technique, they would need multiple PIN/Password generators. Although there is a multitude of options available to confirm individual identification, the 5 effective solutions that are currently available are both complex and costly to implement and maintain. Further, personal computing skill levels of Internet customers vary significantly where there are extreme ranges of competency ranging from novice to expert. As a consequence, financial institutions have adopted the use of the user names/personal identification numbers and passwords as it is the simplest and least costly solution 10 available. Unfortunately, it is also the least effective solution. There exists a need for a device, method and system to securely authenticate a user. Summary of the Invention 15 The present invention seeks to provide a device, system and method which overcomes the drawbacks of the prior art.

Fig. 1 shows an example of an identification system 1 including an identification device 20 10, a base station 20, optionally a user station 30 and a communications network 70. Shown in Fig. 1A, the identification device 10 and user station 30 may be interconnected via a identification-device coupling element 15. The base station 20 and user station 30 may be interconnected via the communications network 70. It will be appreciated that as 25 the user station 30 is optional, the base station 20 and identification device 10 may be interconnected by the communication network 70. It is preferable that one or more gateways may be positioned on the communication network 70 between each user station 30 and base station 20, interconnecting various networks and different communication protocols. 30 WO 2005/115045 PCT/AU2005/000728 - 18 It is noted that the base station 20 can be a financial institution wherein the user station 30 is a customer performing transactions over a network 70. However, the identification system 1 is not limited to this use, and can be used in various other applications such as loyalty point schemes, purchase of products and services, access of private health 5 information, access of private taxation information, access of private company information, voting, and any other systems that require authentication of a user. The identification device 10 is preferably a compact electronic personal identification device that couples to a user station 30, such that it seeks to identify the user or owner. 10 The identification device 10 includes a processor 11, a store 12 including code data (also known as device codes) and an order rule. Preferably, the identification device 10 includes a coupling element 15 to optionally couple the identification device 10 to the user station 30, an encryption module 13 and a decryption module 14. 15 Accordingly, it will be appreciated that the identification device processor 11 may be any form of processor suitably programmed to perform the method, as will be described in more detail below. 20 The base station 20 includes a processor 21 and a store 22 including an order rule and at least one parameter. Preferably the processor 21 may be adapted to perform encryption and decryption. However, optionally the base station 20 may include an encryption module 23, a decryption module 24. 25 The user station 30 is a processing system suitable for performing a method of relaying data between the base station 20 and the identification device 10. In particular, the user station 30 generally includes at least a processor 31, a memory 32, and an input device 33, such as a keyboard, an output device 34, such as a display, an external interface 35, such as a port, coupled together via a bus as shown. The user station 30 can be any type of 30 computer device including workstations, personal computers, network connectable WO 2005/115045 PCT/AU2005/000728 - 19 information-processing devices, digital home electric appliances, ATM, portable terminals for instance, and cellular phones. An example of a method of using the identification system of Figure 1A will now be 5 described with reference to Figure lB. In particular, at step 100, the identification device 10 receives, from the base station 20, request data 50 indicative of at least one parameter. At step 110, the identification device 10 determines at least one algorithm. 10 At step 120, the identification device 10 generates modified code data using the determined at least one algorithm, the received at least one parameter and the code data in the identification device store 12. At step 130, the identification device 10 generates ordered data using the order rule, the at least one parameter, and the generated modified 15 code data. At step 140, the identification device 10 transfers, to the base station 20, response data 60 at least partially indicative of the modified code data. At step 150, the base station 20 authenticates the user of the identification device 10 using the response data 60. 20 An example of the identification system showing the flow of data between the identification device 10 and the base station 20 will now be described with reference to Figure 2A. 25 In particular, the identification system 1 includes the base station 20 and the identification device 10 interconnected by a communications network 70. It will be appreciated that a user station 30 may be interconnected between the base station 20 and identification device 10 for relaying data. The base station 20 includes a store 22 including at least one parameter and at least one algorithm. The identification device 10 includes a store 12 30 including code data. The base station 20 transfers the at least one parameter and the at least WO 2005/115045 PCT/AU2005/000728 -20 one algorithm to the identification device 10. The identification device 10 transfers a generated identification code to the base station 20 to be authenticated. An example of a method of a user being authenticated using the identification system 1 5 described in Figure 2A will now be described with reference to Figures 3A to 3C. In particular, at step 300 the user couples the identification device 10 to the user station 30. At step 305 the user station 30 transfers an access request 40 to the base station 20. 10 At step 310, the base station 20 compares the access request 40 to data in the data store 22. At step 315, the base station 20 determines the success of the comparison. If the comparison was unsuccessful, the base station 20 denies access to the user station 30 at step 320. If the comparison was successful, the method continues on to step 325. 15 At step 325, the base station 20 generates an identification request 50 including an identification code algorithm and plurality of parameters. Preferably the parameters are random numbers used by the identification device 10 for generating a plurality of identification code portions, and for ordering the plurality of identification code portions to generate an identification code. 20 At step 330, the base station 20 encrypts the identification request 50 using the base station's encryption module 23, and at step 335 the base station 20 transfers the identification request 50 to the identification device 10, via the user station 30. 25 At step 340, the identification device 10 decrypts the identification request 50 using the identification device's decryption module 14. At step 345, the identification device 10 generates an identification response 60. The identification response 60 includes an identification code. The identification code is generated using the received identification code algorithm, the plurality of device codes, and the plurality of parameters. 30 WO 2005/115045 PCT/AU2005/000728 -21 At step 350, the identification response 60 is encrypted using the identification device's encryption module 13 and at step 355 the identification device 10 transfers the identification response 60 to the base station 20, via the user station 30. 5 At step 360, the base station 20 decrypts the received identification response 60 including the identification code. At step 365, the base station 20 reversely applies the sent identification code algorithm using the identification code and the sent plurality of parameters so as to determine the identification device's plurality of device codes. The plurality of parameters are used to reorder the identification code and also to regenerate the 10 device codes. At step 370, the base station 20 generates an identification check code using the determined plurality of device codes. At step 375, the base station 20 compares the generated identification check code to data in the data store 22. At step 380, the base 15 station 20 determines the success of the comparison. If the comparison is unsuccessful, the base station 20 denies access at step 385. If the comparison is successful, the base station 20 grants access to the user using the user station 30 at step 390. A more detailed example of the method described in Figures 3A to 3C will now be 20 described with reference to Figures 4A to 4D. In particular, at step 400 the user couples the identification device 10 to the user station 30. The identification device 10 may include a coupling element 15 which couples with an external interface 35 such as a user station port. The port 35 may be a universal serial bus 25 (USB), used to couple to the identification device's coupling element 15. Accordingly, the identification device 10 preferably includes USB/USB2 communications compatibilities. Alternatively, the identification device 10 may include other forms of coupling elements 15 which could be used to couple to other ports 35 such as parallel ports, serial ports, firewire, RS232, RS485 and the like. Optionally, the identification device 10 may include 30 more than one coupling element 15 allowing the identification device 10 to be used on variety of user stations 30 that includes various types of ports 35.
WO 2005/115045 PCT/AU2005/000728 -22 At step 410, the identification device 10 recognises that the identification device 10 has been coupled to the user station 30, and therefore installs driver software on the user station 30. It will be appreciated that the driver software may be installed each time the 5 identification device 10 is coupled to the user station 30, as will be described in more detail later. Alternatively, it will also be appreciated that the driver software may only require being installed the initial time the identification device 10 is coupled to the user station 30. The driver software is used by the user station 30 to control the data transfer between the base station 20 and the identification device 10 via the user station 30, and may also be 10 used by the user station 30 to control the identification device 10. At step 420 the user station 30 transfers an access request 40 to the base station 20. The access request 40 includes a user's username and a password. For example, the user may open a financial institution's web page on the internet using the user station 30. The web 15 page prompts the user for the username and the password. An access request 40 including the username and the password is then transferred to the base station 20. It will be appreciated that the access request 40 including the username and the password may be encrypted. 20 At step 430 the base station 20 compares the received access request 40 to data in the data store 22, and at step 440, the base station 20 determines the success of the comparison. For example, the base'station 20 may decrypt the access request 40 including the username and the password, and compare the unencrypted user name and password to data in the data store 22. If the comparison is unsuccessful (ie. the unencrypted username and password 25 does not exist in the database) then the base station 20 denies access the user using the user station 30 at step 450. If the comparison is successful, the method moves on to step 460. The base station 20 may transfer data to the identification device 10 indicating the success of the comparison. 30 At step 460, the base station 20 generates an identification request 50 including an identification code algorithm and plurality of parameters, wherein the plurality of WO 2005/115045 PCT/AU2005/000728 - 23 parameters are preferably random values. The identification code algorithm may include a number of sub-algorithms, wherein each sub-algorithm is applied to an individual device code in the identification device 10, as will be discussed in further detail later. The identification code algorithm uses both the plurality of random values and the device codes 5 to generate an identification code, as will also be discussed in more detail later. The identification code algorithm and the plurality of random numbers are stored in the base station's data store 22 with the associated received access request 40. The plurality of random numbers are preferably generated by measuring electronic 10 interference (also known as "white noise") so as to generate real random numbers rather than pseudo-random numbers. The identification code algorithm is selected by the base station 20 at random from a plurality of identification code algorithms stored in the base station's data store 22. Similarly, the base station 20 may select the identification code algorithm from the plurality of identification code algorithms using a random number. 15 At step 470, the base station 20 encrypts the identification request 50 using the base station's encryption module 23 and a key stored in the base station store 22. The identification request 50 may be unencrypted using a similar key stored in the identification device store 12. At step 480 the base station transfers the identification 20 request 50 to the identification device 10, via the user station 30. At step 490, the identification device 10 decrypts the identification request 50 using the identification device decryption module 14. As has been previously indicated, the identification device's decryption module 14 uses a key stored in the identification device store 12 to decrypt the identification request 50. 25 At step 500, the identification device 10 applies the identification code algorithm to the plurality of device codes to generate an identification code. As earlier indicated, the identification algorithm includes a number of sub-algorithms, wherein each sub-algorithm is applied to the each device code stored in the identification device's store 12. When each 30 sub-algorithm is applied to each respective device code, one of the plurality of the random numbers is used in order to produce a portion of the identification code.
WO 2005/115045 PCT/AU2005/000728 -24 Each sub-algorithm manipulates a respective device code using one of the random numbers from the received plurality of random numbers. For example, as shown in Figure 9, the first sub-algorithm 2060 is indicative of adding the value of the random number to 5 the value of the device code 2030. Other forms of manipulation, which a sub-algorithm may be indicative of, may include multiplying or subtracting one of the random numbers from the device code, as shown in Figure 9. It will be appreciated that these are simplified examples and that more complex sub-algorithms are possible. 10 At step 510, the identification code is generated by concatenating each generated identification code portion to other identification code portions using an order rule and the values of the received plurality of random numbers, such as to generate an identification 15 code. For example, as shown in Figure 9, the plurality random numbers 2000, 2010, 2020 received in the identification request 50 include a first random number 2000 having a value of '13', a second random number 2010 having a value of '19', and a third random number 20 2020 having a value of '5'. The first random number 2000 is used with the first sub algorithm 2060 and applied to the first register 2030 including the first device code. The result of the first sub-algorithm 2060 produces a first identification code portion 2100. Similarly, the second and third random numbers 2010, 2020 are used with the second and third sub-algorithms 2070, 2080 and applied to second and third registers 2040, 2050 25 respectively, producing the second and third identification code portions 2110, 2120. The identification device 10 includes an order rule 2130, which for example specifies that the identification code portions 2100, 2110, 2120 are to be concatenated together in an ascending order of the value of each random numbers 2000, 2010, 2020 applied. 30 Therefore, the third random number 2020 with a value of five is the smallest, followed by the first random number 2000 with a value of thirteen, and then the second random number WO 2005/115045 PCT/AU2005/000728 - 25 2010 with a value of nineteen. Therefore, the order rule 2130 generates an identification code 2140 by concatenating the identification code portions 2100, 2110, 2120 which includes the third identification code portion 2100, followed by the first identification code portion 2110, followed by the second identification code portion 2120, as shown in Figure 5 9. It will be appreciated that other order rules 2130 could be applied, for example, concatenating the identification code portions 2100, 2110, 2120 in descending order. At step 520, the identification device 10 generates an identification response 60. The identification response 60 includes the generated identification code. 10 At step 530, the identification response 60 is encrypted using the identification device's encryption module 13. The identification device 10 uses a randomly generated key to encrypt the identification response 60. The identification device 10 may measure electronic interference to generate a random key to be used by the encryption module 13 to encrypt 15 the identification response 60. Typically, the encryption module is a Triple DES encryption module. The encryption module 13 and decryption module 14 may be hardware, software, or a combination of hardware and software. At step 540, the identification device 10 embeds the generated random key used to encrypt 20 the identification response 60, in the identification response 60. As such, when the base station receives the identification response, the base station extracts the randomly generated key in order to decrypt the identification response 60. However, it will be appreciated that other forms of exchanging the randomly generated key are possible such as using session keys. It is preferable that encrypted data transfer between the 25 identification device 10 and the base station 20 after step 540 use the randomly generated key. For example, if data is transferred after access is granted, the encryption modules 13, 23 and decryption modules 14, 24 use the randomly generated key in order to encrypt and decrypt data transferred. 30 At step 550, the identification device 10 transfers the identification response 60 to the base station 20, via the user station 30.
WO 2005/115045 PCT/AU2005/000728 -26 At step 560, the base station 20 extracts the random key embedded in the received identification response 60. The base station 20 may extract the random key from the identification response 60 at predetermined locations in the identification response 60. 5 At step 570, the base station 20 decrypts the received identification response 60 using the base station's decryption module 24 and the extracted random key. Typically, the base station's decryption module 24 is a software module however it will be appreciated that the decryption module 24 may be a Triple DES decryption module. The decryption module 24 10 may be hardware, software, or a combination of hardware and software. The decrypted identification response 60 includes the identification code generated by the identification device 10. At step 580, the base station 20 retrieves from the base station's data store 22 the plurality 15 of random numbers sent to the identification device 10 in the identification request 50. At step 590, the base station 20 uses the plurality of random numbers to reorder the identification code portions. Therefore, the base station 20 determines, using the plurality of random numbers, which identification code portion was generated for which device code in the identification device 10. 20 At step 600, the base station 20 retrieves from the base station's data store 22 the sent identification code algorithm. At step 610, the base station 20 reversely applies each sub algorithm to the determined identification code portions using the plurality of random numbers. Thus, by reversely applying the sub-algorithms, the plurality of device codes, 25 stored in the identification device 10, are re-generated by the base station. At step 620, the base station 20 generates an identification check code using the re generated device codes. The base station may include an identification code converter (not shown) that uses the re-generated device codes to produce an identification check code. 30 The identification code converter may be any one or combination of a software program or WO 2005/115045 PCT/AU2005/000728 - 27 hardware to perform the task of converting the plurality of re-generated device codes to an identification check code 18. Preferably the identification check code includes less digits compared to the plurality of 5 device codes such that the base station's data store 22 does not have to record large numbers, and slow down the comparison process performed in step 630. It will be appreciated that the plurality of regenerated device codes are purged from the base station's memory 22 such that the only record of the plurality of device codes in the identification system 1 is in the identification device 10. 10 At step 630, the base station 20 compares the generated identification check code to data in the data store 22. The comparison includes comparing that the identification check code matches the associated user name and password compared earlier at step 430. 15 At step 640, the base station 20 determines the success of the comparison of the identification check code. At step 650, if the comparison is unsuccessful, the base station 20 denies access. If the comparison is successful, the base station 20 grants access to the user using the user station 30 at step 660. Access may be granted by creating a secure sockets layer (SSL) link between the base station 20 and user station 30. 20 Another example of an identification system will now be described with reference to Figure 2B. In particular, the base station includes a store 22 including at least one parameter, and a 25 lookup table including identity data associated with a plurality of identification code algorithms. The identification device 10 includes a store 12 including code data and at least one algorithm. The base station 20 transfers the at least one parameter to the identification device 10. The identification device 10 transfers a generated identification code and identity data to the base station 20 to be authenticated. 30 WO 2005/115045 PCT/AU2005/000728 -28 An example of a method of a using the identification system described in Figure 2B will now be described with reference to Figures 5A to 5C. In particular, at step 700 the user couples the identification device 10 to the user station 30. 5 At step 710 the user station 30 transfers an access request 40 to the base station 20. At step 720, the base station 20 compares the access request 40 to data in the data store 22. At step 730, the base station 20 determines the success of the comparison. If the comparison was unsuccessful, the base station 20 denies access to the user station 30 at 10 step 740. If the comparison was successful, the method continues on to step 750. At step 750, the base station 20 generates an identification request 50 including a plurality of random numbers. At step 760, the base station 20 encrypts the identification request 50 using the base station's encryption module 23, and at step 770 the base station 20 transfers 15 the identification request 50 to the identification device 10, via the user station 30. At step 780, the identification device 10 decrypts the identification request 50 using the identification device decryption module 14. At step 790, the identification device 10 generates an identification code.' The identification code is generated using the 20 identification code algorithm stored in the identification device store 12. The identification code algorithm stored in the identification device 10 uses the plurality of device codes, and the received plurality of random numbers to generate the identification device code. At step 800, the identification device 10 generates an identification response 60 including 25 the identification code and identity data. At step 810, the identification response 60 is encrypted using the identification device's encryption module 13 and at step 820 the identification device 10 transfers the identification response 60 to the base station 20, via the user station 30. 30 At step 830, the base station 20 decrypts the received identification response 60 including the identification code and identity data. At step 840, the base station 20 uses the identity WO 2005/115045 PCT/AU2005/000728 - 29 data to determine, using data stored in the data store 22, the identification code algorithm used by and stored in the identification device 10. At step 850, the base station 20 reversely applies the determined identification code 5 algorithm using the identification code and the sent plurality of random values to determine the identification device's plurality of device codes. At step 860, the base station 20 generates an identification check code using the determined plurality of device codes. At step 870, the base station 20 compares the 10 generated identification check code to data in the data store 22. At step 880, the base station 20 determines the success of the comparison. At step 890, if the comparison is unsuccessful, the base station 20 denies access. If the comparison is successful, the base station 20 grants access to the user using the user station 30 at step 895. 15 A more detailed example of the method described in Figures 5A to 5C will now be described with reference to Figures 6A to 6D. In particular steps 900 to 950 are performed similarly to steps 400 to 450. 20 At step 960, the base station 20 generates an identification request 50 including a plurality of random numbers. The plurality of random numbers are used by the identification device 10 in the identification code algorithm to generate a plurality of identification code portions. The plurality of random numbers may also be used with the order rule to determine an order which the plurality of generated identification code portions are to be 25 concatenated, as previously described. The plurality of random numbers are generated and stored in the base station's data store 22 prior to being sent to the identification device 10. Steps 970 to 990 are performed similarly to steps 470 to 490.
WO 2005/115045 PCT/AU2005/000728 -30 At step 1000, the identification device 10 applies the stored identification code algorithm to the plurality of device codes to generate an identification code. The plurality of random numbers are also used by the identification code algorithm, as shown in Figure 9. 5 Step 1100 is performed similarly to step 510. At step 1020, the identification device 10 generates an identification response 60. The identification response 60 includes the generated identification code and identity data. The identity data includes a device identity to uniquely identify the identification device 10. 10 The identity data may also include a grouping number and a version number. The grouping number may be used by the base station 20 to determine the identification code algorithm stored in the identification device 10. The version number may be indicative of the version of the identification device 10. For example version '1.0' may include two hundred and fifty six device codes, whereas version '1.1' may include five hundred and twelve device 15 codes. Steps 1030 to 1060 are performed similarly to steps 530 to 560. At step 1070, the base station 20 decrypts the identification response 60, similarly to step 20 570. The decrypted identification response 60 includes the identification code and the identity data. Steps 1080 and 1090 are performed similarly to step 580 and 590. 25 At step 1100, the base station 20 retrieves, from the base station's data store 22, the identification code algorithm used by the identification device 10. The base station 20 determines the identification code used by the identification device 10 using the received identity data. Thus the identity data is used as a pointer in a lookup table (or matrix) which includes the identification code algorithms for a plurality of identification devices 10. 30 WO 2005/115045 PCT/AU2005/000728 - 31 Once the identification code algorithm is retrieved, using identity data, the base station 20 performs step 1110 to 1160 similarly to step 610 to 660 so as to authenticate the user of the user station 30 and grant access if a successful authentication occurs. 5 Another example of an identification system will now be described with reference to Figure 2C. In particular, the base station 20 includes a store 22 including at least one parameter, at least one first algorithm. The identification device 10 includes a store 12 including code 10 data and at least one second algorithm. The base station 20 transfers the at least one parameter and first algorithm to the identification device 10. The identification device 10 transfers a generated identification code and identity data to the base station 20 to be authenticated. 15 An example of a method using the identification system described in Figure 2C will now be described with reference to Figures 7A to 7D. In particular, at step 1200 the user couples the identification device 10 to the user station 30. At step 1210 the user station 30 transfers an access request 40 to the base station 20. 20 At step 1220, the base station 20 compares the access request 40 to data in the data store 22. At step 1230, the base station 20 determines the success of the comparison. If the comparison was unsuccessful, the base station 20 denies access to the user station 30 at' step 1240, If the comparison was successful, the method continues on to step 1250, 25 At step 1250, the base station 20 generates an identification request 50 including a plurality of random values and a first identification code algorithm. At step 1260, the base station 20 encrypts the identification request 50 using the base station's encryption module 23, and at step 1270 the base station 20 transfers the identification request 50 to the identification 30 device 10, via the user station 30.
WO 2005/115045 PCT/AU2005/000728 -32 At step 1280, the identification device 10 decrypts the identification request 50 using the identification device decryption module 14. At step 1290, a first identification code is generated by applying the first identification code algorithm using the plurality of device codes and received plurality of random numbers. At step 1300, a second identification 5 code is generated by applying the second identification code algorithm, stored in the identification device store 12, using the first identification code and the received plurality of random numbers. At step 1310, the identification device 10 generates an identification response 60 including 10 the second identification code and the identity data. At step 1320, the identification response 60 is encrypted using the identification device's encryption module 13 and at step 1330 the identification device 10 transfers the identification response 60 to the base station 20, via the user station 30. 15 At step 1340, the base station 20 decrypts the received identification response 60 including the identification code. At step 1350, the base station 20 uses the identity data to determine, using data stored in the data store 22, the second identification code algorithm used by the identification device 10. 20 At step 1360, the base station 20 reversely applies the determined second identification code algorithm using the second identification code and the sent plurality of random values so as to regenerate the first identification code. 25 At step 1370, the base station 20 reversely applies the first identification code algorithm to the regenerated first identification code algorithm using the plurality of random numbers so as to regenerate the identification device's plurality of device codes. At step 1380, the base station 20 generates an identification check code using the 30 determined plurality of device codes. At step 1390, the base station 20 compares the generated identification check code to data in the data store 22. At step 1400, the base WO 2005/115045 PCT/AU2005/000728 - 33 station 20 determines the success of the comparison. At step 1410, if the comparison is unsuccessful, the base station 20 denies access. If the comparison is successful, the base station 20 grants access to the user using the user station 30 at step 1420. 5 A more detailed example of the method described in Figures 7A to 7D will now be described with reference to Figures 8A to 8E. In particular, steps 1500 to 1550 are performed similarly to steps 400 to 450. 10 At step 1560, the base station 20 generates an identification request 50 including the first identification code algorithm and the plurality of random numbers. The first identification code algorithm is selected randomly from the plurality of first identification code algorithms stored in the data store 22. 15 Steps 1570 to 1590 are performed similarly to steps 470 to 490. At step 1600, the identification device 10 applies the first identification code algorithm to the device codes using the plurality of random numbers to generate a plurality of first identification code portions. 20 At step 1610, the identification device 10 applies the second identification code algorithm to generate, using the plurality of first identification code portions and the plurality of random numbers, the second plurality of identification code portions. It will be appreciated that the first and second algorithms are two segments of a total algorithm that is applied to 25 the device codes, as will be described in more detail later. Step 1620 is performed similarly to step 510 except the second plurality of identification code portions are concatenated to generate the identification code. 30 At step 1630, the identification device 10 generates an identification response 60. The identification response 60 includes the generated identification code and identity data. The WO 2005/115045 PCT/AU2005/000728 - 34 identity data includes a device identity and may include a version number, and a grouping number, as has been described in previous examples. Steps 1740 to 1800 are performed similarly to steps 530 to 590. 5 At step 1710, the base station 20 retrieves, from the base station's data store 22, the second identification code algorithm used by the identification device 10. The base station 20 determines the identification code algorithm used by the identification device 10 using the received identity data. Thus the identity data is used as a pointer to a lookup table (or 10 matrix) which includes the identification code algorithms for a plurality of identification devices 10. At step 1720, the base station 20 reversely applies the retrieved second identification code algorithm using the received second plurality of identification code portions and the sent 15 plurality of random numbers so as to regenerate the first identification code. At step 1730, the base station reversely applies the retrieved first identification code algorithm to the regenerated first identification code so as to regenerate the plurality of device codes. 20 Steps 1740 to 1780 are performed similarly to steps 620 to 660 so as to authenticate the user of the user station 30 and grant access if a successful authentication occurs. It is preferable that an identification device distributor distributes the identification devices 25 10 to the base stations 20. The distributor performs a distribution method including loading systemic components including databases and software required to support the identification system 1 onto one or more base stations 20, loading systemic components required to support the particular base stations 20 onto a identification system 1 central site computer and supplier central databases, custom tailoring the relevant base station 30 software/systems to accommodate the new identification information requirements, e.g. the customer system, the internet gateway system, etc., custom tailoring the relevant base WO 2005/115045 PCT/AU2005/000728 -35 station databases to accommodate the new identification information requirements, establishing relevant support procedures at the base station offices and branches, and, performing QA on all procedures and systems affected. 5 It is preferable that an ongoing operational process occurs between the identification device distributor and each base station 20 included in the identification system 1. The ongoing operational processes that provide support for the identification system 1 are expected to be conducted daily by the identification device distributor and each base station 20 on a one-on-one basis. Typically such processes would include supply of the 10 physical identification device 10 stocks by the identification device distributor to the relevant base station 20, registering the identification devices 10 sent onto the supplier's central databases, registering the identification devices 10 received onto the base station 20 database. It is also perceived that such processes would include distributing the identification devices 10 to the relevant base stations 20 wherein the base station 20 can 15 redistribute the identification devices 10 to their customers, performing daily batch processes to prepare transmission files on each base station 20, transmitting identification device 10 activity data to the identification device 10 supplier's central site computer. Additionally, these processes could include processing on the identification device supplier's central site computer daily identification device 10 activity received from each 20 base station 20 in order to summarise all activities, and, transmitting report files, and warnings to each base station 3. It is preferable that there is a registration process for a user to obtain an identification device 10. This registration process is only expected to occur once, unless the customer 25 has, damaged, or reported the identification device 10 as lost or stolen. Typically, a customer visits a base station 20 and applies to use an identification device 10, the base station 20 provides the customer with a "conditions of use" contract, the customer reads the "conditions of use" contract, signs, and returns it to the base station 20. 30 The base station 20 detaches the identification check code tag attached to the identification device 10, and provides the customer with an identification device 10, WO 2005/115045 PCT/AU2005/000728 - 36 relevant software such as device drivers or useful software such as internet browsers, and instructions. The base station 20 enters the identification check code 18 printed on the identification check code tag into the customer database , and, the base station 20 then destroys the tag containing the identification check code, as it is no longer required. 5 Variations Referring to Figure 2D, the identification device 10 may include a third identification code algorithm stored in the identification device's memory 12, which is transferred from the identification device 10 to the base station 20. Thus, referring now to Figures 7A to 7D and 10 8A to 8E, once the second identification code algorithm has been applied and generates the second identification code, the second identification device code is used by the third identification code algorithm, thus generating a third identification code. The identification device 10 then generates the identification response including the third identification code algorithm, the third identification code, and the identity data. When the base station 20 15 receives the identification response 60, the base station 20 reversely applies the third identification code algorithm to obtain the second identification code. Once the base station 20 obtains the second identification code, the base station 20 can apply the first and second identification code algorithms as per Figures 7A to 7D and 8A to 8E so as to regenerate the plurality of device codes. 20 The first and second and third identification code algorithms may be separate segments of a total algorithm. Therefore, the identification device 10 may combines the separate segments of the algorithms in order to generate a total algorithm so as to generate an identification code. 25 The base station 20 may transfer in the identification request 50 an indicator indicative of an incorrect sub-algorithm. As such, the identification device 10 applies the plurality of sub-algorithms correctly except for the specified sub-algorithm. As such, when the base station 20 regenerates the device codes and creates an identification check code, the 30 identification check code shall be partially incorrect. If the identification check code is WO 2005/115045 PCT/AU2005/000728 - 37 partially incorrect, access is granted. If the base station 20 requested a partially incorrect identification check code and the identification check code is correct, access is denied. It is preferable that the identification device 10 is a lightweight device that typically 5 weighs less than ten grams, perhaps most preferably between five and ten grams. The identification device 10 may optionally include a hook such that it can be easily attached to a key ring carried by a user. The identification device 10 is able to fit in a pocket of a person's clothing or a purse/wallet. 10 The identification device 10 is ideally enclosed in a casing, wherein the casing is substantially difficult to open. The casing prevents hackers from opening the identification device 10 and copying the device codes in an attempt to reproduce a mimic device. The casing could be welded tight, or include a one-piece moulding. The casing could be made from a rigid material, making it substantially difficult for a hacker to open and copy the 15 device codes. The casing can include a self-destruct mechanism such that when the casing is opened, the device codes are damaged or deleted from memory substantially preventing a hacker copying the identification device 10. The identification device 10 may include a serial number imprinted on the outside of the 20 case. The serial number is a reference number that the base station 20 can use to identify the device. The serial number may be recorded in the base station's data store 22 such that a record is kept by the base station 20 as to which user possesses a particular identification device 10. 25 It is preferable that the identification device 10 includes security protection against false identification requests. A hacker may attempt to send a false identification request to the identification device 10 to determine the device codes. The false properties of the identification request 50 may be determined from time and date stamps, incorrect formatting, or any other properties included in the identification request 50, which can 30 indicate to the identification device 10 that a false request has been received. As such, the identification device 10 detects the false identification request 50 and produces a false WO 2005/115045 PCT/AU2005/000728 - 38 identification response 60, therefore providing the hacker with no indication as to whether the identification request 50 was correct, and also providing the hacker with incorrect information. The identification device 10 may generate a random number, preferably using electronic interference (as previously discussed), in order to generate a false identification 5 code. When the identification device 10 is coupled to a user station 30, a data log is sent to the base station 20 to record tampering with the identification device 10. This can preferably be used as input for changing the identification algorithm codes. It is preferable that the base station 20 can indicate to the identification device 10 that the log is to be cleared from the identification device store 12. This may be performed by the base station 10 20 transferring data to the identification device 10 indicative of clearing the log from the identification device store 12. The base station 20 may transfer data indicative of requesting the identification device 10 to clear the store 12 of the data log at the discretion of the base station 20. 15 The identification device's memory 12 (also known as the store) may have a capacity that varies between a few bytes up to a number of gigabytes. Preferably, the identification device 10 includes an internal power source to power the identification device 10. Whilst the identification device 10 is coupled to the user station 20 30, the power supply may recharge. Alternatively, the identification device 10 may be a passive device, wherein the identification device 10 is powered whilst coupled to the user station 30. When the identification device 10 recognises that it has been coupled to a user station 30, 25 the identification device 10 may install driver software included on the identification device 10 onto the user station 30. This helps prevent previously installed driver software from being tampered with and being used by the identification device 10. The identification device 10 may also update the driver software whilst coupled to the user 30 station 30. This may include the base station 20 recognising that a new version of driver WO 2005/115045 PCT/AU2005/000728 - 39 software exists and transfers, via the user station 30, the updated driver software to the identification device 10. The plurality of random numbers generated by the base station 20 may be formatted in a 5 particular order prior to being transferred to the identification device 10. For example, the base station 20 may require that the third random number is not larger than the first random number. Optionally, two or more identification devices 10 may be coupled to a user station 30 in 10 order to authenticate associated users simultaneously. For example, a business may require two or more identifications in order to perform a transaction. Therefore, two or more identification devices 10 may be coupled to the user station 30 and each identification code requires authentication before the transaction is allowed to continue. 15 The identification device 10 may preferably include a smart card port to couple with smart cards or similar devices. The identification device 10 optionally includes continual session authentication, wherein a plurality of identification requests are received throughout the session whilst the base 20 station provides granted access. The base station 20 may request authentication that the identification device 10 is still coupled to the user station 30 preventing the removal of the identification device 10 from the user station 30 during the granted access. This feature also prevents a connection to the base station 20 being left open, liable for security attacks. Therefore, if the identification device 10 is uncoupled from the user station 30, the granted 25 access from the base station 20 is terminated. Failure of the identification device 10 to transfer an identification response to the base station 20 within a time period may result in the granted access being terminated. The identification device 10 may include a temperature sensor to measure the temperature 30 of the identification device 10. If the temperature measured using the sensor is determined WO 2005/115045 PCT/AU2005/000728 -40 to be outside a predefined temperature range including a minimum and maximum threshold, the device codes are deleted or damaged in the identification device 10. It is preferable that the authentication of the usemame and the password occur prior to the 5 authentication of the identification device 10. However, it is appreciated that the authentication process could occur at substantially the same time or in a reverse order. Optionally, if the user station 30 or identification device 10 is idle for a particular period of time whilst access is granted, the session may be terminated by the base station 20, thus 10 authentication may again be required. The identification system 1 is not limited to internet access, as it equally applies to any form of network access authorisation such as complementing an existing customer card personal identification number utilised for Automatic Teller Machines or EFTPOS devices. 15 The identification system 1 optionally includes multiple base stations 20. The secure information stored on each base station 20 may be different to information stored on other base stations 20 in the network. However, all base stations 20 in the network share records including the identification check code, such that a single identification device 10 can be 20 used for different base stations 20. Optionally, other information may be recorded in the base station's data store 22. This may include information indicative of particular states of the identification device 10 such as if it has been issued, lost, damaged, or stolen, with associated dates and times may also be 25 stored. Other details that are recorded may include login details such as times of authentication, session periods, transfer of data, processes carried out. It is preferable that the identification system 1 includes a backup server able to backup information stored in the base station 20. Preferably the data is backed up daily, such that 30 if the data becomes corrupted, the data can be restored in a timely manner.
WO 2005/115045 PCT/AU2005/000728 -41 Optionally, the base station 20 may include software that generates and transmits reports containing activity details, activity warnings, general warnings and details of suspected fraudulent activities as well as statistical and management information. It is also preferable that the base station 20 includes software that summarises all activities by a base station 20 5 for a particular time period. Although the present invention has been described in terms of the presently preferred embodiments, it is to be understood that the disclosure is not to be interpreted as limiting. Various alterations and modifications will no doubt become apparent to those skilled in the 10 art after having read the above disclosure. All such alterations and modifications should be considered within the spirit and scope of the invention as broadly herein before described.
