Blockchain: The safest place for our data

By Louise Broderick Of all the conceivable uses of blockchain, its potential in securely managing, storing and sharing data is, I would say one of the most exciting of all. At its core, blockchain enables the sharing of data across boundaries.

Drones: It’s all about the data

By Stephen Mills The latest Instagram fad, according to a recent report, is to take a selfie (preferably while somewhere exotic on holiday) from a drone. Inevitably it comes with its own hashtag – #instadrone.

How Data & Analytics tools can improve your tax function

By Tom Harrold. Tax functions are under pressure to become more efficient and aligned with the business, whilst also handling greater amounts of information. All against the backdrop of increasingly complex regimes. Could data and analytics provide a solution?

Financial crime: Sanctions screening and the quirks of language

By Scott Samme and Jeremy Davey. For virtually any company participating in international trade, sanctions screening has long been an everyday fact of life. It can’t be avoided and, for most, is one of the most time-consuming and frustrating of compliance processes. But it needn’t be.

Why the role of Data Engineer could be the catalyst your business needs

By Sam Jones and Timothy Harrison In our last blog we discussed how the combination of increased data availability and customer expectations was driving the opportunity for increasingly personalised policies.  The insurance industry has been built on data foundations with underwriting, claims and reserving all creating data and pertaining processes which are enhanced through the use of data.

Regulatory technology insights

We were recently invited by one of our Banking clients to participate in a panel discussion at their annual Fintech innovation week. We shared views on emerging technologies, the impact they’ve had on operations and compliance, and how they’re helping the sector provide valuable services to customers. The main theme of our discussion was advanced data analytics, artificial intelligence and machine learning, and how regulatory developments, and compliance costs are influencing the rapid adoption of these technologies. We’ve summarised a few of the main points in part one of this two part blog.

The role of analytics in wellbeing

Back in the analogue days, annual appraisals were the main tool organisations used to find out how their employees were feeling. Appraisals could be a hit-and-miss affair for many reasons – not least that the appraisal process itself is enough to put some people in a bad mood. And if the employee is having an ‘off’ day on appraisal day, that’s it, as far as their employer is concerned they’re unhappy for a year.

Financial crime: Four essential rules for effective transaction monitoring

By Jeremy Davey and Scott Samme Money launderers are, by definition, a devious bunch. They quickly learn the rules that banks set to detect suspicious transactions, and adapt. They are, in other words, dynamic – so transaction monitoring should be equally so. In our previous blog we talked about the problems with many legacy transaction monitoring (TM) systems, which tend to be rules-based. That’s not to say that rules-based systems are obsolete; but in the complex world of global finance, they’re not enough on their own. If banks are to efficiently root out complex illegal trades they need to know far more about the connections between parties to transactions. Fortunately, advanced technology and analytics allow us to do this.

When automated pricing becomes collusion

By David Geere Machine learning systems are not unlike raising a particularly brilliant child – they could move ahead and gain knowledge at speed, but you need to give them guidance and an ethical framework or they could break through lines that adults wouldn’t cross. The possibility of automated collusion is one of those lines. As I’ve written previously, pricing is one of the most important issues for any business and Data and Analytics is bringing huge advantages to companies in making pricing decisions. Competition is tough in every sector, and companies are understandably keen to get the best prices for their goods and services

Connecting with senior females in data

By Cathy Wilks For a long time we’ve thought about how do we really connect with more like-minded female technologists who all share the same passion for data, analytics and emerging technology. There are many events that we could, and often do attend, however, as senior females in data, we really want to understand how we can make a difference. As two of the female data leaders at PwC, last month we hosted the first gathering for ‘female leaders in data’ in our offices at Embankment Place. We recognise how important it is to form support networks, particularly with female peers, given there are fewer women in senior technology roles.

Blockchain, a solution to securing and managing personal data?

By Jeff Handler and Leigh Bates It’s no secret that the amount of personal data being collected and processed is rapidly increasing. It’s estimated that over 20% of all of the world’s data has been collected in just the last couple of years, and that this will continue to increase exponentially moving forward.

Transaction monitoring: Why segments and thresholds are never enough

By Scott Samme and Jeremy Davey In our last blog we talked about the difficulties banks face with transaction monitoring (TM) for anti money laundering (AML) purposes. Rapid developments in data analytics and machine learning will make TM far more efficient in the very near future – but banks need to get their existing systems in order first.

At PwC, we’ve delivered several AI solutions that provide augmented decision making to help our clients act with speed and precision at scale.

Personalised Policies

By Sam Jones The insurance sector has always been known for being data-driven, in fact, some of the most early data analytics was with actuaries and insurance underwriters. The new challenges we face today is the sheer volume and variety of data which is increasing exponentially; a wealth of data is being generated by the increasing number of devices we interact with on a daily basis – from our mobile phones to the Internet of Things (IoT) - all of which provide high volume, mix-structured information on a real-time basis.

Financial crime: Towards better transaction monitoring

By Jeremy Davey and Scott Samme In our last blog we explored how to use data and technology to understand your customers, for the third blog in our financial crime series we've looked at transaction monitoring systems and how technology and data analytics can help make transaction monitoring more efficient.

Outperforming the human: How can machine learning help your business?

By Matthew Tomlinson Every week, it seems someone produces a new estimate for how much data we produce. According to the research company IDC, by 2025 we will have created 163 zettabytes. That’s the equivalent of 40 trillion DVDs, or the entire Netflix catalogue 489 million times over. Technology allows us to gather, organise and analyse these vast volumes of data – but a potential weakness remains, and that stems from human involvement.

Data visualisation: following the money

By Andrew Souyave I was talking to a friend recently who has an IT system where she works that gives things away free. It doesn’t mean to, it just lets the users close out contracts without going through the manual step of raising an invoice. When the friend had looked...

Unlocking the power of data to track and manage business traveller risks

By Arjun Kumar and Sarah Mullen In an increasingly connected world, business travel is essential for companies to maintain and expand their global footprint. So it's no surprise that according to the Global Business Travel Association, in 2016 worldwide organisations spent US$1.3 trillion (approx £1 trillion) on business travel. However, together with great opportunities, this can equally be problematic for companies, as authorities are increasingly scrutinising the activities of mobile workers.

Tech for good: Using data and technology to pick out the bad apples

Stop. Think. Automate. Repeat.

By Peter Chastin  People are amazing. They can perform incredibly complex tasks, and achieve astounding goals, especially when working together. They are an organisation’s most valuable asset, and often considered to be irreplaceable in their role. Despite this, there are daily tasks that are performed by people in their jobs that are, quite frankly, not worth their time. Time is valuable as well as finite, and can be better spent on innovation than on the same task every day.

Chatbots - Let’s talk about them

There are three things you should know about me - I’ll tell you two of them now. Firstly, I like talking. I’ll talk to strangers, to colleagues, to clients; I’ll talk to the radio even though I’m reasonably sure they can’t hear me. Secondly, I hate filling out forms. I hate that once you’ve filled out one form you have to fill it out again twenty minutes later. I hate having to navigate to section 27b if I don’t own my own home or have a pet with arthritis. Wouldn’t it be good if we could use technology to get rid of this, whilst increasing the data integrity? This is why I believe chatbots are so appealing.

Algorithmic trading: Flash crash or flashback?

By Aminul Ali, Leigh Bates Earlier this month, when the Dow Jones fell by almost 5%, what followed quickly overshadowed any blame on human error. Prices in the US stock market experienced free fall over a period of 15-20 minutes. The shocks were felt sharply in the S&P 500, Japan’s Nikkei and, closer to home in the UK, the FTSE 100.

Data and analytics: Protecting us against financial crime part 1

By Jeremy Davey and Scott Samme The Chicago mobster Al Capone is famously (and perhaps erroneously) credited as the source of the phrase ‘money laundering’ in the 1940s, after his laundromat businesses were used to legitimise cash he gained through less salubrious means. Even Capone might have been surprised at how the money laundering business has boomed since his days. Our Global Economic Crime Survey shows the scale of the problem: global money laundering transactions worldwide are estimated at between $1 and $2 trillion – that’s 2% to 5% of the world’s total GDP. Less than 1% of this money is ever recovered by the authorities.

The Gender Big Data Gap

By Harjinder Kaur - PwC, Navin Haram - UN Women and Fiona Bayat-Renoux - UN Women “To achieve gender equality and empower all women and girls” is the fifth of the 17 Sustainable Development Goals (SDGs) set out in the United Nation’s plan, Transforming our world: the 2030 Agenda for Sustainable Development. In our previous blogs we’ve discussed how big data can be used to monitor and evaluate international development. Big data can give us great insights into aid effectiveness and development projects, but it also comes with its own challenges.
