The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

Will UK Retailers Skim the Cream with ESOS?

The British Retail Consortium (BRC) was quick out on the starting blocks with an ambitious plan to cut energy costs by 25% in 5 years. Their ?25-in-5? initiative is chasing a target of ?4.4 billion savings during the duration. Part of this program involves ?cutting a path through a complex and inaccessible policy landscape?. BRC believes this drawback is making its members think twice about making energy efficiency investments.

The UK?s sprawling network of grocers, department stores and malls is the nation?s second most hungry energy customer, having spent ?3.3 billion on it in 2013 when it accounted for almost 20% of carbon released. If you think that sounds bad, it purchased double that amount in 2005. However the consortium believes there is still more to come.

It bases this assumption on the push effect of UK energy rates increasing by a quarter during the duration of the project. ?So it makes sense to be investing in energy efficiency rather than paying bills,? Andrew Bolitho (property, energy, and transport policy adviser) told Business Green. The numbers mentioned exclude third party transport and distribution networks not under the British Retail Consortium umbrella.

The ?complex and inaccessible policy landscape? is the reflection of UK legislators not tidying up as they go along. BRC cites a ?vast number of policies ? spreading confusion, undermining investment and making it harder to raise capital?. The prime culprits are Britain?s CRC Energy Efficient Scheme (previously Carbon Reduction Commitment) which publishes league tables and ESOS. Andrew Bolitho believes this duality is driving confused investors away.

The British Retail Consortium is at pains to point out that this is not about watering things down, but making it simpler for participating companies to report on energy matters at a single point. It will soon go live with its own information hub providing information for retailers wishing to measure consumption at critical points, assemble the bigger picture and implement best practice.

Ecovaro agrees with Andrew Bolitho that lowering energy demand and cutting carbon is not just about technology. We can do much in terms of changing attitudes and providing refresher training and this does not have to cost that much. Studies have shown repeatedly that there is huge benefit in inviting employees to cross over to our side. In fact, they may already be on board to an extent that may surprise.

What GDPR Means in Practice for Irish Business

The General Data Protection Regulation (GDPR) is a European directive aimed at ring-fencing consumer data against illegal or unnecessary access. There is nothing to discuss or debate with local politicians, or the Irish Data Protection Commissioner for that matter. As a European directive, it has over-riding power. To obtain an English version, please visit this link, and select ?EN? from the table of languages.

As you reach for your tea, coffee or Guinness after sighting it, you will be glad to know the Irish Data Protection Commissioner has the lead in turning this into business English we understand. The following diagram should assist you to obtain a quick overview of the process we all have to go through. In this article, we briefly describe what is inside Boxes 1 to 12. The regulation comes into force on 25 May 2018 so we have less than a year to get ready.

The 12 Essential Steps to Implementing the General Data Protection Act

1. Create awareness among your people of what is coming their way. The GDPR has given our regulator discretion to dish out fines up to ?20,000,000 (or 4% of total annual global turnover, whichever is greater) so there is determination to make this happen.

2. Become accountable by understanding the consumer data you hold. Why are you retaining it, how did you obtain it, and why did you originally collect it. Now you know it is there, how much longer will you still need it? How secure is it in your hands, have you ever shared it?

3. Open a communication channel with your staff, your customers, and anyone else using the data. Share how you feel about how accountable you have been with the information in the past. Explain how you plan to comply with the GDPR in future, and what needs to change.

4. Understand the personal privacy entitlement of the subjects of the information. They have rights to access it, correct mistakes, remove information, restrict its use, decline direct marketing, and copy it to their own files. What needs to change in your systems to assure these rights?

5. Issue a policy for allowing consumers access to their information you hold. You must process requests within a month, and you may not charge for the service unless your cost is excessive. You may decline unfounded or excessive demands within your policy guidelines.

6. Adapt to the requirement that you must have a legal basis for everything you do with, and to consumer data. You need to be in a position to justify your actions to the Irish Data Protection Commissioner in the event of a complaint. Having a legitimate interest is no longer sufficient.

7. Ensure that consumer consent to collect, use, and distribute their data is ?freely given, specific, informed, and unambiguous.? From 25 May 2018 onward, this consent will be your only ground to do so. You cannot force consent. Your benchmark becomes what the GDPR says.

8. Issue rules for managing data of underage subjects. This is currently under review and we are awaiting results. Put systems in place to verify age. Set triggers for where guardians must give consent. Make sure age is verifiable. Use language young people understand.

9. Introduce a culture of openness and honesty, whereby breaches of the GDPR are detected, reported, investigated, and resolved. You will have a duty to file a GDPR report with the Data Protection Commissioner within 72 hours, thus it is important to fast track the process.

10. Introduce a policy of conducting a privacy assessment before taking new initiatives. The GDPR calls for ?privacy by deign?, and we need to engineer it in. This may be the right time to appoint a data controller in your company, and start implementing the GDPR while you have time.

11. You may also need to appoint a data protection officer depending on the size of your business. Alternatively, you need to add managing data protection compliance to an employee?s duties, or appoint an external data-protection compliance consultant.

12. Finally, and you will be glad to know this is the end of the list, the GDPR has an international flavour in that multinational organisations will report into the EU Lead Supervisory Authority. This will manage the process centrally while consulting national data authorities.

The GDPR is a project we all need to complete. If we are out of line, it is in our interests to get things straightened out. Once everything is in place, the task should not be too onerous. Getting there could be the pain.

8 Reasons why you Need to Undertake Technical and Application Assessments

Are your information assets enabling you to operate more cost-effectively or are they just drawing in more risks than you are actually aware of? Obviously, you now need to get a better picture of those assets to see if your IT investments are giving you the benefits you were expecting and to help you identify areas where improvements should be made.

The best way to get the answers to those questions is through technical and application assessments. In this post, we?ll identify 8 good reasons why it is now imperative to undertake such assessments.

1. Address known issues – Perhaps the most common reason that drives companies to undertake a technology/application assessment is to identify the causes of existing issues such as those related to data accessibility, hardware and software scalability, and performance.

2. Cut down liabilities and risks – Unless you know what and where the risks are, there is no way you can implement an appropriate risk mitigation strategy. A technology and application assessment will enable you to thoroughly test and examine your information systems to see where your business-critical areas and points of failure are and subsequently allow you to act on them.

3. Discover emerging risks – Some risks may not yet be as threatening as others. But it would certainly be reassuring to be aware if any exist. That way, you can either nip them in the bud or keep them monitored.

4. Comply with regulations – Regulations like SOX require you to establish adequate internal controls to achieve compliance. Other regulations call for the protection of personally identifiable information. Assessments will help you pinpoint processes that lack controls, identify data that need protection, and areas that don’t meet regulatory requirements. This will enable you to act accordingly and keep your company away from tedious, time-consuming and costly sanctions.

5. Enhance performance – Poor performance is not always caused by an ageing hardware or an overloaded infrastructure. Sometimes, the culprits are: unsuitable configuration settings, inappropriate security policies, or misplaced business logic. A well-executed assessment can provide enough information that would lead to a more cost-effective action plan and help you avoid an expensive but useless purchase.

6. Improve interoperability – Disparate technologies working completely separate from each other may be preventing you from realising the maximum potential of your entire IT ecosystem. If you can examine your IT systems, you may be able to discover ways to make them interoperate and in turn harness untapped capabilities of already existing assets.

7. Ensure alignment of IT with business goals – An important factor in achieving IT governance is the proper alignment of IT with business goals. IT processes need to be assessed regularly to ensure that this alignment continues to exist. If it does not, then necessary adjustments can be made.

8. Provide assurance to customers and investors – Escalating cases of data breaches and identity theft are making customers and investors more conscious with a company?s capability of preserving the confidentiality of sensitive information. By conducting regular assessments, you can show your customers and investors concrete steps for keeping sensitive information confidential.
