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.

Malware

In the past, viruses were created with the sole purpose of wreaking havoc on the infected systems. A large fraction of today’s malware, on the other hand, are designed to generate revenues for the creator. Spyware, botnets, and keyloggers steal information from your system or control it so that someone else can profit. In other words, the motivation for making them is now more attractive than before.

Keyloggers can reveal your usernames, passwords, PIN numbers, and other authentication information to their creators by recording your key strokes. This information can then be used for breaking into various accounts: credit cards, payment programs (like PayPal), online banks, and others. You’re right, keyloggers are among the favourite tools of individuals involved in identity theft.

Much like the viruses of old, most present day malware drain the resources, such as memory and hard disk space, of contaminated systems; sometimes forcing them to crash. They can also degrade network performance and in extreme cases, may even cause a total collapse.

If that’s not daunting enough, imagine an outbreak in your entire organisation. The damage could easily cost your organisation thousands of euros to repair. That’s not even counting yet the value of missed opportunities.

Entry points for malware range from optical disks, flash drives, and of course, the Internet. That means, your doors could be wide open to these attacks at this very moment.

Now, we’re not here to promise total invulnerability, as only an unplugged computer locked up in a vault will ever be totally safe from malware. Instead, this is what we’ll do:

Perform an assessment of your computer usage practices and security policies. Software and hardware alone won’t do the trick.
Identify weak points as well as poor practices and propose changes wherever necessary. Weak points and poor practices range from the use of perennial passwords and keeping old, unused accounts to poorly configured firewalls.
Install malware scanners and firewalls and configure them for maximal protection with minimal effect on network and system performance.
Implement regular security patches.
Conduct a regular inspection on security policy compliance as well as a review of the policies to see if they are up to date with the latest threats.
Keep an audit trail for future use in forensic activities.
Establish a risk management system.
Apply data encryption where necessary.
Implement a backup system to make sure that, in a worst case scenario, archived data is safe.
Propose data replication so as to mitigate the after effects of data loss and to ensure your company can proceed with ‘business as usual’.

Once we’ve worked with you to make all these happen, you’ll be able to sleep better.

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.

User-Friendly RASCI Accountability Matrices

Right now, you’re probably thinking that’s a statement of opposites. Something dreamed up by a consultant to impress, or just to fill a blog page. But wait. What if I taught you to create order in procedural chaos in five minutes flat? ?Would you be interested then?

The first step is to create a story line ?

Let’s imagine five friends decide to row a boat across a river to an island. Mary is in charge and responsible for steering in the right direction. John on the other hand is going to do the rowing, while Sue who once watched a rowing competition will be on hand to give advice. James will sit up front so he can tell Mary when they have arrived. Finally Kevin is going to have a snooze but wants James to wake him up just before they reach the island.

That’s kind of hard to follow, isn’t it ?

Let’s see if we can make some sense of it with a basic RASCI diagram ?

Responsibility Matrix: Rowing to the Island
Activity	Responsible	Accountable	Supportive	Consulted	Informed
Person	John	Mary	Sue	James	Kevin
Role	Oarsman	Captain	Consultant	Navigator	Sleeper

Now let’s add a simple timeline ?

Responsibility Matrix: Rowing to the Island
?	Sue	John	Mary	James	Kevin
Gives Direction	?	?	A	?	?
Rows the Boat	?	R	?	?	?
Provides Advice	S	?	?	?	?
Announces Arrival	?	?	A	C	?
Surfaces From Sleep	?	?	?	C	I
Ties Boat to Tree	?	?	A	?	?

Things are more complicated in reality ?

Quite correct. Although if I had jumped in at the detail end I might have lost you. Here?s a more serious example.

There?s absolutely no necessity for you so examine the diagram in any detail, other to note the method is even more valuable in large, corporate environments. This one is actually a RACI diagram because there are no supportive roles (which is the way the system was originally configured).

Other varieties you may come across include PACSI (perform, accountable, control, suggest, inform), and RACI-VS that adds verifier and signatory to the original mix. There are several more you can look at Wikipedia if you like.
