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.

Mobile Security

Today’s advanced enterprises make extensive use of mobile devices in order for team members to exchange information, collaborate, and carry out business whenever and wherever they need to. BlackBerries, iPhones, Google Phones, and other smartphones as well as PocketPCs and PDAs are now allowed wireless remote access to the enterprise network.

As a result, they introduce additional vulnerabilities into the system.

  • Bluetooth exploits and unencrypted passwords can allow malicious individuals to gain access to private information.
  • Various wireless technologies that have substantially simplified the task of transferring data have provided openings for malicious code. In addition, the diversity of these wireless technologies combined with the constrained environments of these devices have made it difficult to come up with an all-in-one solution.
  • All PocketPCs, PDAs and smartphones can be synchronised with PCs and laptops, giving malware an entry point into computers and networks. Memory cards are guilty of this too.
  • VoIP, which are usually unencrypted, allow other people to perform unauthorised capture and recording of private conversations.

Mobile security is still an emerging discipline. Because of this, many organisations that allow members’ mobile phone access into the network don’t actually have a specific security policy for such devices.

That’s why we’re here to help. We’ll conduct a thorough evaluation of your security policies and systems in relation to mobile devices and seal gaps we spot along the way. If you don’t have the needed policies or if what you have needs an overhaul, we’ll set everything up (including the needed applications and infrastructure) for you.

Once we’ve got everything in place, you won’t have to worry about the vulnerabilities mentioned earlier. In addition to that, your organisation will already be capable of preventing the following:

  • Access to company information when the phone ends up in the hands of anyone other than the authorised user.
  • Being billed for phone usage due to virus activity
  • Unauthorised phone activity monitoring through spyware
  • Other disruptions caused by mobile-based malware

Importance of Field Service Management Software for Mobile Working

Technology has been evolving at a fast pace. Changes are also happening simultaneously within different industries. Making a great difference in the business world right now is the trend of mobile working.

Thanks to platforms and tools, working while on the go is now easier and more streamlined. The field service industry also benefits from these technological advances.

Mobile technicians can now give excellent performance and do their job efficiently with no hands-on management needed.

Keep in mind that field service management is no joke. So, to achieve a smooth business and mobile worker management, you’ll need to invest in good mobile service management software.

But First, what is Mobile Working?

Mobile working is a method of working that is not tied to a single physical location.

It isn’t just about checking your emails on your phone or ringing your colleagues via Bluetooth while driving your car to the next appointment. It’s so much more intricate than that.

Effective mobile working means you’re mobilising your workers. Field technicians should have everything they need to complete their day to day work. You’re giving them their entire office in the form of a mobile device.

Mobile working, via a handheld device, allows field technicians to do the following:
● Access and input information about a work order
● Collaborate on projects
● Stay in touch with colleagues, clients and management
● Utilize effectively the different software features

Your field workers should have the support of a dynamic management tool that ensures they are sent to the job that utilises their skills effectively and efficiently.

That’s where a good field service management software shows its importance.

The Role of a Field Service Management Software

Your mobile workforce is scattered across various physical locations. You’ll need to connect with them and simultaneously manage your field service business.

Thanks to the increasing connectivity and improvement of technologies for this purpose, mobile workers can easily input and access any work order details via your chosen field service management software.

What Makes a Good Field Service Management Software?

There are 3 main points to consider when investing in a good mobile workforce management software:

1. It’s simple and familiar to use. Like we mentioned before, be sure to mobilise your field technicians – not the back-office system. Make sure your chosen app or software has a simple user interface so your workers can be on-the-go easily.

2. It works offline. Rural areas and highways can have poor connectivity. Sometimes agents will need to work in areas that have little to no network coverage or are deep down working in tunnels or around heavy machines and turbines. You don’t want your field technicians unable to complete work due to connectivity issues. Make sure to choose software that can function on their device while offline.

3. It’s flexible (and maintainable). Your field service management of choice should have real-time visibility. Flexible and improved visibility for a field worker means that they can do their best in any task. They can share or get critical information about orders and customers. This drastically improves job completion rates and customer satisfaction.

Importance of Field Service Management Software to Mobile Working

Utilize the technology that is available to you. Your mobile workforce should have the right tools so they can make sure to do their fieldwork efficiently without worrying about tedious administrative work. Any back-office task can be done quickly through a field service management software.

And that’s the most important role of a great mobile service management app — effective mobile worker efficiency.

Benefits of a Field Service Management Software to Mobile Working

● Additional revenue: By simplifying the administrative work, your field technician can even double the work order in their daily shift, meaning more profit for the business.

● Cost-cutting: The cloud-based nature of a field service management software means that your business can reduce the cost of on-site IT.
Your mobile workforce can operate from wherever they have an online connection, meaning less reliance on offices and building costs.

● Boosts overall efficiency: A mobile workforce management software allows you as a manager to monitor in real-time where they are and what they are doing. It means that problems can be identified and dealt with immediately.
Your field technician, in turn, becomes more efficient because the technology allows them a quicker response, instead of taking too long finishing administrative tasks.

A Definitive List of the Business Benefits of Cloud Computing

When you run a Google search for the “benefits of cloud computing”, you’ll come across a number of articles with a good list of those. However, most of them don’t go into the details, which nevertheless might still suit some readers. But if you’re looking for compelling business reasons to move your company’s IT to the cloud, a peripheral understanding of what this technology can do for you certainly won’t cut it.

Now, cloud computing is not just one of those “cool” technologies that come along every couple of years and which can only benefit a particular department.?What we’re talking about here really is a paradigm shift in computing that can transform not only entire IT infrastructures but also how we run our respective organisations.

I hate to think that some people are holding back on cloud adoption just because they haven’t fully grasped what they’re missing. That is why I decided to put together this list. I wanted to produce a list that would help top management gain a deeper understanding of the benefits of the cloud.

Cloud computing is one bandwagon you really can’t afford not to jump into. Here are ten good reasons why:

1.?Zero?CAPEX and low TCO for an enterprise-class IT infrastructure

2. Improves cash flow

3. Strengthens business continuity/disaster recovery capabilities

4. Lowers the cost of analytics

5. Drives business agility

6. Ushers in anytime, anywhere collaboration

7. Enhances information, product, and service delivery

8. Keeps entire organisation in-sync

9. ?Breathes life into innovation in IT

10. Cultivates optimal environments for development and testing

Zero CAPEX and low TCO for an enterprise-class IT infrastructure

Most cloud adopters with whom I’ve talked to cite this particular reason for gaining interest in the cloud.

Of course they had to dig deeper and consider all other factors before ultimately deciding to migrate. But the first time they heard cloud services could give them access to enterprise class IT infrastructures without requiring any upfront capital investment, they realised this was something worth exploring.

A good IT infrastructure can greatly improve both your cost-effectiveness and your capability to compete with larger companies. The more reliable, fast, highly-available, and powerful it is, the better.

But then building such an infrastructure would normally require a huge capital investment for networking equipment, servers, data storage, power supply, cooling, physical space, and others, which could run up to tens or even hundreds of thousands of euros. To acquire an asset this costly, you’d have to take in debt and be burdened by the ensuing amortisation.

If you’ve got volumes of cash stashed in your vault, cost might not be a problem. But then if you really have so much savings, wouldn’t it be more prudent to use it for other sales-generating projects? An extensive marketing endeavour perhaps?

A capital expenditure of this magnitude and nature, which normally has to be approved by shareholders, can be regarded as a high financial risk. What if business doesn’t do well and you wouldn’t need all that computing power? What if the benefits expected from the IT investment are not realised??You cannot easily convert your IT infrastructure into cash.

Remember we’re talking about a depreciating asset. So even assuming you can liquidate it, you still can’t hope to sell it at its buying price. These factors are going to play in the minds of your Board of Directors when they’re asked to decide on this CAPEX.

Incidentally, these issues don’t exist in a cloud-based solution.

A cloud solution typically follows a pay-as-you-go utility pricing model where you get billed monthly (sometimes quarterly) just like your electricity. ?In other words, it’s an expense you’ll need to pay for?at the end of a period over which the service’s value would have already been realised. Compare that with a traditional infrastructure wherein you’ll have to spend upfront but the corresponding value will still have to be delivered gradually in the succeeding months or years.

demand expense traditional infrastructure

From the point of view of your CFO, what could have been a CAPEX to acquire an asset that depreciates with time (and consequently reduces your company’s net worth), becomes a flexible operating expense (OPEX).?Truly, it is an operating expense that you can increase, decrease, or even totally discontinue, depending on what the prevailing business conditions demand.

demand expense cloud infrastructure

People who think they have done the math in comparing cloud-based and traditional IT infrastructures claim that, although they see how cloud solutions transform CAPEX into OPEX, they really don’t see any significant difference in overall costs.

However, these people have only gone as far as adding up the expected monthly expenses of a cloud solution over the estimated duration of an equivalent IT infrastructure’s effective lifespan and comparing the sum with that IT infrastructure’s price tag. You won’t get a clear comparison that way.

You need to consider all factors that contribute to the infrastructure’s Total Cost of Ownership (TCO). Once you factor in the costs of electricity, floor space, storage, and IT administrators, the economical advantages of choosing a cloud solution will be more evident. Add to that the costs of downtime such as: interruptions to business operations, technical support fees, and the need to maintain expensive IT staff who spend most of their time “firefighting”, and you’ll realise just how big the savings of cloud adopters can be.

Still not convinced? Well, we’re still getting started.?On our next post, we’ll take a closer look at the additional benefits of paying under an OPEX model instead of a CAPEX model.
