COUNTERMEASURES FOR IRREGULARITIES IN FINANCIAL TRANSACTIONS

Abstract: A system and method for identifying financial transactions with the potential for financial irregularity (e.g. money laundering) comprises processing (20) financial transactions connected with a client, account and financial application, subjecting the client/account and transaction information to a set of rules (22) to produce numerical outcomes (116, 124, 132) indicative of the potential for money laundering being present. A user of the system is able to vary the weightings associated with each rule according to their importance to the particular circumstances of the institution in question.

Description: COUNTERMEASURES FOR IRREGULARITIES IN FINANCIAL TRANSACTIONS FIELD OF THE INVENTION This invention relates to countermeasures against irregulaiities in financial transactions. More particularly, the invention relates to money laundering countermeasures. Still more particularly, the invention relates to systems and methods for enabling financial institutions to meet standards compliance on money laundering countermeasures. BACKGROUND OF THE INVENTION Money laundering is the process of providing a false provenance for money so as to conceal its true origin. It is of benefit to criminals seeking to introduce the proceeds of crime into the legitimate financial world. The opportunities for devising money laundering techniques have expanded with the increasing flexibility of electronic funds transfer systems. As the volume of financial transactions and the speed of processing them have increased, particularly with the advent of e-commerce, the responsibility on financial institutions in playing their part in detecting and reporting money laundering activity has become more burdensome. Essentially, the process of detecting a financial transaction that is the subject of an attempt at money laundering is a subjective one. Two people tasked with assessing the same transaction on the basis of client, account and transaction data may well come to different conclusions as to whether it is suspicious or not. Such an assessment assumes the transaction is being dealt with as an individual matter without any constraint of time. The volume of traffic through financial transactions does not allow purely human consideration of each and every transaction. One way to address this is to sample only a fraction of the transactions and to assess them. Of course, this does not provide a comprehensive picture of all the transactions passing through a financial institution. It also relies on chance. While this may lead to a train of enquiry concerning a particular client or account, it is not a comprehensive analysis. Because money laundering is such a major problem, allowing criminals to enjoy the benefits of their crimes, national governments are looking to financial institutions to provide assistance in the fight against the problem. Financial institutions, such as banks, must set up systems to detect money laundering to be in compliance with, for example, European and/or US money laundering legislation. Other countries have their own compliance criteria. While it might be possible for a financial institution to do business in states in which it complies with the local anti-money laundering requirements, this is not actually a practicable solution. A significant proportion of the world's trade is conducted in US dollars. The anti-money laundering legislation in the United States is particularly burdensome on financial institutions. If money transferred into the United States turns out to be criminal in origin, the US authorities have the power to pursue the financial institution that conducted the transaction through the US courts. As all Dollar transactions have to be subjected to US clearing, there is an automatic US jurisdiction for all dollar- based transactions. The Organisation for Economic Co-operation and Development (OECD) has established its own Financial Action Task Force on Money Laundering (FATF) which produced The Forty Recommendations' for best practice compliance with its anti-money laundering objectives. To date twenty-nine states, the European Union and the Gulf Co-operation Counsel are signatories to The Forty Recommendations. Part of these makes uniform the code of practice which the financial institutions have to meet in order to exhibit best practice in money laundering countermeasures. However, there is still the problem of compliance itself even with the beneficial degree of uniformity imposed by The Forty Recommendations. Recommendation 15 of The Forty Recommendations states that a financial institution, suspecting that funds stem from a criminal activity, should report their suspicions promptly to the competent authorities. A bank is basically a medium fransmitting money in and out. It is required first to identify transactions that are suspicious. Thus, the problem faced by such a financial institution is how to be in compliance with best practice as a reflection of The Forty Recommendations in view of the volume and speed of transactions in current banking systems. Sophisticated artificial intelligence techniques have been applied to the problem of monitoring fraudulent financial activity. This has been in the belief that such adaptive solutions are the only way to detect the complex and subtle signs that could indicate misbehaviour. Artificial intelligence involves the software in 'learning' from its previous analyses to refine its approach. It is not possible for anybody but the most highly trained programmers to tune the procedures once they are set up. Thus, while artificial intelligence itself is adaptive, it does not allow relatively lower level tuning by a user. It is also configured to detect fraud which is not the same as identifying transactions with the potential for financial irregularity for the purposes of compliance. SUMMARY OF THE INVENTION It is an object of the present invention to provide a method of enabling a financial institution to identify fransactions that may be suspicious. The present invention provides a new approach to the concept of identifying such transactions by which the financial institution can achieve compliance with prevailing best practice requirements governing financial fransaction irregularities. It is a further object of the invention to provide a system for use by financial institutions that provides a basic framework for providing an alert to potentially suspicious transactions which is user variable according to need and circumstances. According to one embodiment of the present invention there is provided a method of alerting to the potential for a financial irregularity in a financial fransaction. The method is based on a set of rules which assist in providing an alert to the potential for the presence of a financial irregularity in the fransaction. Accounts can be monitored to establish a pattern of such fransactions. By running the set of rules in respect of a financial fransaction in the account, outcomes relative to the established pattern are produced. Such outcomes include any transgressions of the rules indicative of any potential for an irregularity being present. A set of user-established weighting functions can be applied to the outcomes of running the rules, whereby they provide a weighted outcome indicative of the potential for a financial irregularity being present. The weights can be set by the financial institution as user of the method. Similarly, the user can impose thresholds on the degree of transgression of the rules or the cumulative total so that only those rules scoring above a certain threshold level will contribute to an alert of a potentially suspicious transaction. By using a simple set of rules, the user is able to tune the system to specific requirements without recourse to sophisticated programming techniques. The basis of the invention is the recognition that it is possible to scrutinise in detail a relatively smaller number of fransactions that are identified as having a greater potential for being irregular so that a decision can be made on whether to report them to the competent authorities. The invention can operate by assessing what is normal in a set of archived transactions and evaluating each transaction subsequent to the archived set from that datum. In this way the invention is able to identify transactions which could turn out to be worthy of further investigation. The invention uses the set of individual rules to determine those fransactions which are candidates for suspicion. These may be based on the fundamental principles of the value of transaction(s), velocity of the fransaction(s) and the volume of fransactions effected in the given time. According to another embodiment of the invention, there is provided a system for identifying a potential for financial irregularity in a financial fransaction, comprising: a first database for storing data on at least one selected fransaction; a processor loaded with a rules engine, mcluding a set of rules for determining a potential for the presence of financial irregularity in at least one selected fransaction, the processor being operable to access the data in the database to run the set of rules in respect of the data and to produce an outcome indicative of the potential for a financial irregularity being present in the transaction. The invention also extends to a computer-readable medium having computer executable instructions for performing the method of the invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Referring to Figure 1, a money laundering countermeasures system comprises an application layer 10, a interface layer 12 and an implementation layer 14. Financial applications are typically provided to support bank accounts, such as retail, wholesale, mortgage loan and insurance accounts, held by bank clients. An exfract routine 16 at the interface layer 12 is supplied with client, account and financial fransaction data from the financial applications at layer 10. These data are stored in a data storage device 18 to form the database that is reviewed at the implementation layer 14 in accordance with the invention. Figure 2 illustrates the client, account and fransaction data that is held in the data storage device 18, as extracted from the financial applications layer 10. The client data forms the basis of the account data. In turn, each transaction associated with an account is based on account data and additional activity data. This is conventional financial data and will not be explained further as it will be well understood by the person of ordinary skill in the art. As illustrated, accounts and clients themselves may be linked or associated for the purposes of fransaction analysis. The implementation layer 14 comprises a money laundering countermeasure processor 20 which accesses the relevant data from the data storage device 18. The accessed data is subjected to a set of fixed (but updatable) rules by a rules engine routine 22 in the processor 20. The outcome of processing the client account/fransaction data according to the rules is a score according to its potential for being a suspicious activity. The data is stored in an archive 24. The outcome of each application of the rules by the rules engine 22 is an output from the processor 20 is a score for the application of each rule relevant to the client/account/fransaction data being analysed. These are placed in a compliance monitoring file for review by a compliance officer of the financial institution. The file is reviewed as an output of the system by the compliance officer as containing those analysed transactions having a score based on application of the rules that places them in the category of being worthy of alerting as potentially suspicious events. By imposing a suitable limit on the number of fransactions referred to the compliance officer, and by listing the outcomes according to their score in descending order, the number of fransactions for human review is kept to a manageable fraction of the total set of fransactions analysed in a review period. According to the invention the user is able to prioritise the rules by applying different weighting functions to different rules and according to the circumstances of the financial institution. Thus, the limit on the alerts put before the compliance officer can be set by establishing that the number of alerts that will be shown will be those in a top band of highest scores. Each rule can be effectively disabled by setting the weighting function to zero. The financial institution, as user of the system, can also set thresholds above which a rule is said to be transgressed for the purposes of the fransaction analysis. An output for a user is only generated when the threshold is exceeded in the score it achieves as a result of running each rule. Setting the weights, thresholds and limits is an input task carried out by the user's system adrninisfrator. The fransactions are downloaded into the database layer 12 and batch processed in a dormant or less busy period of the financial institution's daily or other cycle. For example, the system preferably is a stand-alone arrangement which works on a batch of transactions overnight when the bank is closed for business. Alternatively, the fransaction analysis according to the invention can be accomplished at any other convenient frequency and time, such as at weekends. Once the batch of fransactions has been processed, those brought to the attention of the compliance officer in the form of an output can be reviewed individually. The system of the invention is able to process the transaction data by fetcliing it using the exfract program referred to previously by which it is downloaded to the data storage device 18 which is a sequential file of the data. This is illustrated in Figure 3. Each financial application 10 has its own database 26 from which the relevant data is extracted by the extract routine 28 to the database 18. The processor 20 reads data from the sequential file 18 and applies the rules engine 22 and commits the transaction to the archive 24. Thus, the system of the invention can process fransactions in institutions that use more than one financial application system by extracting the data through the sequential file and normalising it for the purposes of the money laundering countermeasures analysis. Furthermore, by extracting the data from the financial application itself, the money laundering analysis can be conducted without affecting the ability of the financial application to continue processing other fransaction data. The basis to the system of this embodiment of the invention is a rules-based protocol. The rales themselves are explained in more detail below. They are derived from the practical circumstances in which money laundering takes place. As such, their detail is a constantly changing distillation of the mechanisms by which the threat of money laundering can be put into effect. However, while they are loaded in the system, they are each a fixed entity which will lead to a fransaction having a score according to the rale applied and its weighting. By simply estabhshing the rules with separate numerical outcomes the system administrator is able to maintain and tune the system. The rales are based on The Forty Recommendations in the preferred embodiment. However, the detail in the rules is the domain of the skilled person in the particular application and circumstances concerned. Concerning money laundering countermeasures in a banking institution according to one embodiment of the invention, the rales preferably cover all aspects of the banking business, including retail, personal and corporate transactions, both domestic and international. Because the rules are discrete, the institution itself is able to choose the rales it applies to the various categories of accounts by way of the system administrator. Thus, rules can be tuned to a bank's needs and the profile of the customer base in each category. The rales in the set are ranked or weighted so that an outcome of an important or significant rale in determining the potential for the presence or absence of money laundering has greater influence on the decision to scrutinise a fransaction than a lesser rule. The rankings of all the rules fripped by a fransaction will determine the degree of weight allocated to the overall outcome as rules broken in respect of the same fransaction/account/client can be grouped in a user output or actually added up to give an overall tally. A fransaction that frips a minor group of rales may have a lower accumulated influence than a fransaction that might trip only one major rule. The rules are adjustable for sensitivity relative to one another and also overall by the intervention of the system administrator. In the case of relative sensitivity, the rules can be adjusted to suit individual user requirements. If a fransaction scores low in respect of a rule such that it does not appear as a alert strong candidate for further investigation (or does not appear at all if a threshold is used), its risk ranking is simply stored. If a related fransaction (i.e. one that belongs to the account or to a linked account or to the client or to a linked client) later frips another rule, the rankings are combined and may cause the account or client common to the combined fransactions to be the subject of an alert. Certain combinations of rales, when broken by the same transaction, can be seen as especially risky. These combinations are termed meta rales. When a meta rule is broken, the fransaction takes on the risk ranking of each of the component broken rales, plus an enhanced risk ranking associated with the occurrence of the combination. This serves to promote it in its risk ranking. Central to money laundering countermeasures is the country of source or destination of a fransaction. In this embodiment of the invention, an updatable country code list includes every country in the world and weights them according to how concerned the institution should be about receiving funds from or sending funds to each of them. Countries of particular concern are highlighted as 'hot list countries'. This weighting is derived from guidance issued by such organisations as the OECD and the US Department of the Treasury, Office of Foreign Assets Control (OFAC), and from warnings issued by other governments and regulatory bodies. In addition, the list of countries indicates whether or not a country is a member of the FATF. This is significant as institutions in FATF member countries are entitled to assume certain standards of conduct about the money laundering countermeasures performed by their peers in other FATF-member countries and regions. Currencies can be given weightings independently of the jurisdiction involved. Financial transfer mechanisms (such as the system for sending international payment messages operated by the Society for Worldwide Interbank Financial Telecommunication (SWIFT), and automated clearing houses, for example the Clearing House Interbank Payments System (CHIPS) set up by the New York Clearing House for settlement of U.S. international foreign exchange and eurodollar fransactions) can be analysed so that weighted rankings can ultimately be given to particular combinations of individual, institution, routing, currency and remitting/receiving jurisdictions. This is a form of meta rule analysis by which certain combinations of rale category violations occurring together represent a transaction with an enhanced likelihood for money laundering potential. Those wishing to abuse the financial systems to launder money will often seek to escape detection by using several accounts. According to this embodiment of the invention it is possible to combat this by grouping together accounts which are probably linked (for example, several accounts with the same home address or the same customer) and treating their fransactions as though they are passing through one account only. This is not an automatic process, but a proactive analytical tool that has to be set up by the system administration staff running the system. The present invention may also make use of 'fuzzy matching' and other analytical tools, such as data mining and generic reporting tools, to allow linking and grouping accounts together. These are well known in themselves to the person of ordinary skill in the art and will not be described in further detail here. Grouped accounts selected by variables can also be re-analysed by one or more rule sets with different sensitivities if required. Thus, the user can look more closely at defined sets of customers using particularly tailored rule set parameters. This can be used to support a particular investigation or in the more general case of undertaking a due diligence exercise, for example during a take-over of one financial institution by another. When a suspicious fransaction becomes an alert by the system according to its score, the compliance officer can choose one of four actions. Firstly, the fransaction and/or the account can be archived without action. Secondly, the account can be monitored from the time the alert is made. Thirdly, the account can be referred for a second opinion. Fourthly, the account can be referred direct to the competent authorities policing money laundering in the relevant jurisdiction. Whichever action the compliance officer decides to take, it is preferable that there is a requirement for the compliance officer to enter their reason and that the action taken is password enabled. The alert and the action taken is entered in a log and forms part of a complete 'audit trail' of decisions. The log itself is unalterable, although further information can be added to the log at a later date. The system maintains a full history for any account once it is has been marked as suspicious for any reason. The system is able to generate a number of user-defined management and other reports. For management, the system can report detailed data to be used to control the system, to identify patterns of activity and usage, to develop new business rules and to monitor effectiveness of use. In order to provide evidence of compliance with reporting requirements, the system can produce reports to show, for example, numbers of alerts raised, numbers of alerts as a percentage of transactional volumes and action taken. Generally speaking there are objective and relative sets of rales so that certain types and levels of activity can be caught regardless of the customer type, while others are triggered only in relation to the normal recent activity of that customer or customer type. For example, rules may make reference to a arge' deposit or transfer. 'Large' is defined both objectively, as determined by the institution system administrator and according to the usual magnitude of fransaction for the type of business, and also relatively, when compared with the usual activity on that account. Further distinctions in the weighting of relative rules are then made according to the fransaction type, currency, jurisdiction, and the like. This embodiment of the invention is particularly suited to the international institution. It can operate across all sectors of a financial group, whatever their location and jurisdiction by exfracting data and processing it offline and establishing tuned rule sets for differing local requirements. In such an international institution, it is envisaged that there will be one 'master' cenfre running the system and several 'junior' cenfres, each serving a specific jurisdiction or system environment. The master centre is operably connected with the junior centres to receive data on fransactions processed by means of the present invention in order to provide a group overview. As well as allowing different rule sets to be implemented according to jurisdiction or product group, varying reporting filters and thresholds can be imposed locally. As the present invention has been designed to look for changes in fransaction patterns, users of the system are also able to highlight fraudulent transactions as suspicious by means of the same process. A further benefit of this is that the system can be adapted so that the institution can be alerted to those fransactions which are intended to defraud the institution itself. A financial institution having a branch network in which the invention is implemented is shown in Figure 4. The head office 30 has the dominant Rule Set 0. It has access to the databases of Regional Offices 32, 34 and 36 having either different rule sets or no rule set at all. In the latter case, the money laundering counter measures are conducted in accordance with the invention by the head office 30 using rale set 0. Similarly, branch offices 38...54 have rule sets overseen by an administrating regional office or have no rale set, passing access to their databases to the superintending regional rule sets or back through to the head office rule set. The institutions can have as many combinations of rule sets as it needs. Different rales and rale weightings can be applied to transactions going through different branches of a bank. This enables local knowledge and concerns to be reflected in which transactions are brought to the attention of the local compliance staff. Rule sets are usually defined to reflect the structure of the organisation so that the rale set which applies to a regional office will also apply to the branches below it in the organisational hierachy, but not necessarily to the head office. Branches may have their own rale sets being applied across transactions, but this functionality enables the organisation to monitor compliance operations at different levels within its organisational structure. It is also possible to arrange for (e.g.) a head office to review the transaction analysis conducted by a branch office by applying its own rule set to the same transactions. Figure 5 illustrates the relationship between rale sets and will be used to describe rule sets for fransaction and client/account processing according to the invention. The rule set 60 exists in the rules engine as an owner of a collection of rules. Its only attribute is a description. It has no executables as such. The user of the system according to the invention maintains the Rule Set 60. In Figure 5 it is marked as the originator of instructions to the various rules under rule set types as described below. The Rules entity 62 defines the set of rale parameters that can be performed by the system as a whole and from which the Rule Set entity 60 selects the rules for a particular circumstance. The rules themselves will be described in more detail below. The attributes of the Rules entity 62 are a short description (i.e. rule name), a full description (i.e. a descriptor of the rule implemented) and three parameter descriptions. Meta Rules entity 64 is the specified collection of rales which, if broken, will acquire an extra weighting in view of the importance attached to such a combination of broken rules. For example, if the Reggie and Ronnie rules (referred to below) are broken during processing in which deposits are made which are larger than average for a postcode (zipcode) in respect of a balance that is also larger than average for the same postcode, there is heightened cause for suspicion. Both the basic Rules entity 62 and the Meta Rules entity 64 are preferably maintained by the system provider preferably by way of updates at regular intervals to subscribers. The system user maintains a list in Rule Set Rules entity 66 which can be fine tuned so that the processing conducted by the rales engine specific to the user is relevant to their needs. It is in the Rules Set Rules entity 66 that the user can specify the weightings that will be applied to the rules provided by the system provider. These are the basic structural components of the system according to the invention. The system is designed such that the user is able to get the benefit of the rules-based processing, but which is fine tuned by the user itself, by adopting those rules relevant to the circumstances, and weighting the rales also according to their importance and relevance to the user situation. The invention also allows the head office to delegate rule fine timing to branches or regional offices within a group hierachy. The Rules entity 62 essentially consists of quantitative processes providing outcomes that are positioned on a numerical scale according to the rules adopted and the weightings used when applied to a fransaction. In addition, the system of the invention processes fransactions according to certain alerting criteria which, if fripped, provide a weighted value according to the presence or absence of that criteria. As with the quantitative rales, these present/absent criteria are weighted to provide a contribution to a total outcome in respect of a fransaction. Of course, any one such criterion can exact an 'alert' outcome on its own if it is deemed to be a particularly high probability aspect of an irregular fransaction. A Rule Set Country entity 68 allows the user to specify the weights against fransactions coming from and destined for specific countries. Countries of high financial standing would normally attract a low weighting value, whereas countries not, for example, subscribing to The Forty Recommendations of FATF (for example) will attract a significantly higher weighting value. A Rule Set Currency entity 70 allows the user to specify weights against transactions that are in a specific currency. Again, the degree of unreliability of a particular currency will determine the weighting applied to it. A Rule Set Country Currency entity 72 allows the user to specify weights a- gainst transactions in a specific currency corning from or destined for a specific country, i.e. Russian roubles from Austria, to pick an arbitrary example. A Rule Set BIC (bank identification code) entity 74 allows the user to specify weights against fransactions destined for or corning from specific BIC's according to the reliability of the source or destination of the banking transaction being effected. A Postcode entity 76 allows the user to specify alerting weighting to be assigned to certain postcodes in a jurisdiction. There is no direct relationship between postcode and any of the other rule entities. However, the rales engine will use this to check to see if an account or client has breached fransaction limits normally associated with fransactions going to or corning from that particular postcode. It is found that postcode analysis in this way is a useful initiator for determining financial irregularities before a pattern specific to a client or account has been built up in the archive 24 of Figure 1. Rules engine processing is initiated by the rules engine 22 which is passed either a reference to a client, an account or a fransaction and to which the rales set specific to the office of the subscribing financial institution is applied. Analysis has shown that there are two types of rales. Firstly, those that can be applied to fransactions. Secondly, those that can be applied to either an account or a client. A transaction is checked by the rules engine 22 to see the extent to which any of the following rules have been broken, the outcome being in accordance with any thresholds and weightings imposed by the user: These are the rules that apply to the fransactions data. Once, all the data for fransactions for an account, or linked group of accounts, have been processed, the account data is then passed to the rules engine 22 for processing. Once all the accounts for a client have been processed, the client data will be passed to the rules engine for processing. The following rales are applied against an account or client: The Mule Smurf and Smurf rales may be processed more than once for different types of accounts, such as cash, non-cash and mixed fransactions. Linked accounts or clients can be processed together in running these rales. When processing transaction-related data the interface engine utilises the rules engine to process four categories of data and the associated rules, namely: Exchange rates • Client-related data • Account-related data • Transaction-related data This is illustrated in Figure 6. The interface data is read at 80 from the interface database 18. If all the data has been processed at step 84, this aspect of the system is complete. If not, the exchange rate, client-related data, account- related data and transaction-related data is updated at steps 86, 90 and 92, respectively. The processes are illustrated in Figures 7 to 10. In Figure 7, at B.1 in Figure 6 the exchange rate table 96 on which the rales engine is to process transaction- related data is updated by the processor 20 at step 94. These exchange rates are used when converting fransaction amounts into base currency. In Figure 8 at C.l the processor 20 verifies the existing client data in a client table 98 at step 100 or creates a new client entity in the table at step 102. When a client record exists, it is updated at step 103 and the amended records applied to the client table 98. The option to update is available to pass client data from the financial application running the client to the money laundering countermeasures system. The benefit is that all updates to client and account data (see below) is passed automatically to the countermeasures system. As illustrated in Figure 9, at D.l in Figure 6 the processor 20 loads new accounts and amends existing accounts in an account table 104 with the data passed to it at step 106 or creates an account at step 108 in the account table. When an account record exists, it is updated at step 109 and the amended records applied to the account table 104. At E.1 in Figure 6 (shown in Figure 10) the transaction processing itself is dealt with. Each transaction is treated as a new transaction at E.l. Thus, for each fransaction passed to the processor 20, a new fransaction entry is created in a transactions table. Before each transaction is loaded, a decision is made as to whether the account or the client has changed, if so the rules set are then applied to a) the account and b) the client. If not the transaction itself can be processed at F.l described below. Of course, if the fransaction in respect of which the client or account is being analysed is the first one, there is no need to run the account/client rules as there will have been no changes. Thus, at step 111 in Figure 10 this is determined. The account/client rules are bypassed if this is the case and the fransaction itself is subjected to its rales at F.1. Referring to Figure 11, if the client is changed at step 110 of Figure 10 (G.l) the branch or other office of the financial institution having custody of the client is identified at step 112 of Figure 11. If there has been no change of client, the routine passes to the next stage at step 110. The rale structure making up of the rale set for that branch is fetched such that the rales are applied at step 114. According to the outcome of running the rules a score is produced. Tins is determined at step 116. According to the score from each of the rales, an alert is sent to the compliance officer (as in Figure 1) at step 118 if it is sufficiently high relative to the existing alerts to warrant a user output or, alternatively, if it exceeds a threshold imposed on that rule. In Figure 12, a similar process is executed in respect of the account rules at H.1 as shown in Figure 11 for the client rules. The branch or office is identified at step 120, the rules for that branch or office applied at step 122 and a score in respect of breakage of the rales is determined at step 124 as the outcome. The alert is made as an output to the compliance officer at step 126 as necessary. As with clients, at each change of account data at step 113 in Figure 10, the account based rules are applied against the account. If there are no changes in account data the account rales are not applied. At F.l in Figure 6, which is shown in Figure 13, fransaction data is loaded into the database. The rules relevant to the transaction are identified at step 128 for processing the fransaction. The rules relevant to fransaction data are applied against the fransaction at step 130. The determination as to whether any of the applied rules are broken is made at step 132 to give an outcome and an alert issued to the compliance officer at step 134. The following is a two month transaction history for a fictitious account for an individual. The following rules have been selected by the financial institution holding the account according to their own selection of rules in the rules engine. • High Transaction - Transaction amount is over a threshold • Cash Placement Velocity - Frequency of cash deposits increases relative to a specified period of account history • Non-cash Bounce - A large non-cash deposit is mirrored by a withdrawal of similar size in a specific time period • Hot Country - The transaction originates from a designated 'Hot' country (e.g. Russia) All the above rules are defined by parameters of amount thresholds and time periods established by the system administrator. Firstly, the Z Ltd deposits are salary and can be discounted as such. From 25/8 through 1/10 there is evidence of what can comfortably be interpreted as 'normal activity, involving salary deposit and modest withdrawals by cash or standing order. From 10/10 through 19/10 there is evidence of activity that has broken rules because it is within the definition established by the system administrator as being sufficiently suspicious enough to warrant further investigation because it has greater potential for being money laundering. Transactions 13566, 13578, 13600, 13642, 13657 are deemed as suspicious because none reflects the 'normal' activity demonstrated between 25/8 and 1/10 which is stored in the archive. Transaction 13546 is deemed as potentially suspicious because it is the first appearance of a 'hot' currency in the account, the fact that it is a hot country in itself and because it breaches the 'high' transaction rules. Transaction 14567 is deemed as potentially suspicious because it follows 6 small deposits and is in itself a large withdrawal. Figure 14 shows the on-screen display that is available to the head office compliance officer. This is the initial screen showing the Alerts folder 140 and the sub-folders for the compliance officer's alerts 142, and the alerts 144 for the branch offices for the financial institution. The screen shows the Alerts folder 144 is open and the set of three accounts and one client entry that have triggered alerts and their potential for suspicious activity according to the Score column 146. The accounts are listed in order of their accumulated score for the fransaction made in respect of it in a review period. The Status column 148 is filled in by the compliance officer according to the action taken. Figure 15 shows the fransaction listing in date order with the Score for each rule broken. Each time a rule is broken it becomes a new entry. A datafile 150 for the alert in respect of fransaction Txn42769, for example, is shown at 152. This is accessed by clicking on the fransaction entry itself. From the alerts in the background it will be seen that the transaction triggered three rules, namely that it is a fransaction from a 'Hot' country, an OFAC listed country and constitutes a suspicious country/currency combination. Each entry can be clicked on to access the datafile as part of the archive function. The range of score for each rale can be set by the system administrator. A preferred range is between 0 and 255. The range will determine the level of refinement in the outcomes produced by running each rule. Figure 15 shows the three triggered rules in respect of fransaction 42769 scored 75, 75 and 70, respectively. In Figure 14 the cumulative total score in respect of each processed account is given, providing an overall impression to the compliance officer of the account from the point of view of the potential for money laundering. Figure 16 shows the on-screen display for the account action history 154 associated with account 9033 from the Westminster Office. This is accessed by clicking on the account entry 154. The platform on which the money laundering countermeasures system of the invention can be run depends on the size of the financial institution using it. The performance of the system will depend upon the capacity and configuration of the technical environment. A small private client institution with, for example, 300 high value clients, with a handful of fransactions per day would be able to run the system over a Microsoft Access database on a laptop. A larger organisation with, for example 300,000 clients processing 100,000 transactions per day may require an enterprise type database, such as Oracle Version 8.0.3 running on a multi-processor facility. A high street bank with millions of accounts and tens of millions of transactions per day would also require an enterprise type database also running on a multi-processor facility. The rules engine itself is arranged to run on Microsoft Windows NT 4.0 for most applications except the smallest. The software for the system by which the method of the invention is executed can be stored on any suitable computer readable medium such as floppy disk, computer hard drive, CD-ROM, Flash ROM, non-volatile ROM and RAM. The medium can be magnetically or optically readable. It will be apparent to the person of ordinary skill in the art that variations can be made to the invention. Such variations are intended to be embraced without departing from the spirit and scope of the present invention as defined in the following claims.
