BLOCKCHAIN: HELPING SECURE OUR DIGITAL IDENTITIES

David Pollington, Senior Director Technology, GSMA

Blockchain, the backbone technology behind Bitcoin, has grown rapidly since its creation in 2008. Since 2013, Google searches of “blockchain” have risen by 1900% with 90 per cent of banks now exploring blockchain technology according to Accenture. Blockchain technology is being used in an increasing number of industries beyond financial services, including telecommunications, media and the public sector which is no surprise when many argue that technology may provide better security, transparency and efficiency. In fact, it’s not only businesses that are set to benefit from this technology, but millions of people too, thanks to the unique set of attributes that make it a useful tool to help secure our digital identities.

The digital world has played a huge part in disrupting the process of identifying an individual. Historically, this process has been fairly straightforward. For example, a government institution could verify the name and address of a citizen by conducting identity checks with banks or telecommunication providers. As these organisations are regulated to ‘know their customers’, they are able to corroborate the information held by the government institution and therefore verify the identity. Digital identities need to function in a similar way to this – but it’s much harder.

In a digital world without tangible, in person interactions, establishing trust and ownership may be difficult. This is where the blockchain comes into play. Blockchain technology allows individuals, independent of each other, to rely on the same shared, secure and auditable source of information for managing identity. When using this technology in conjunction with a mobile authentication service like the GSMA’s Mobile Connect, blockchain could be the key to securing our digital identities.

Blockchain basics

When a user’s information is added to the blockchain, it is inserted as a single block containing the user’s identity attributes and the user’s public key, all signed with the user’s private key. At this stage, the level of confidence in the user’s identity is at base level. Other entities, such as a bank or electricity provider also represented within the Blockchain can establish relationships with the user by signing the particular attributes of the user that are relevant to that relationship. So for example, the Passport Office could sign the address, name, and photograph of the subject if the attribute values match those on record at the Passport Office.

As the blockchain is used more and more, relationships are established for each person and confidence in the accuracy of the attributes (and the identity) grows. As more transactions take place involving that individual, the ‘reputation capital’ of the identity also grows. In other words, confidence in the identity’s accuracy increases as does confidence in the trustworthiness of the person behind it. And if any of the relationships change, this will be recorded in a separate block with a cryptographically signed timestamp that is visible to the entire blockchain.

The combined power of blockchain and mobile authentication

One critical aspect of any modern, digital service is finding the right balance between convenience and security. Security in the blockchain is upheld with public and private keys. The public key is used to identify the specific user involved, almost equivalent to a user ID. Whereas the private key is the credential that the user needs to keep protected, the private key equivalent to a password or biometric.

However, it is not that simple. A public key is not a convenient “user ID” and the private key is not something that can be easily remembered (like a password) or even be unique to that person (such as a biometric). It is a real challenge to securely store the private key to ensure that it can’t be used by others while being able to easily use it to verify the associated identity.

One solution is to introduce the concept of a wallet through which each person can confirm their attributes and manage their public and private keys. This wallet could be identified through a more convenient user ID, such as the user’s mobile phone number and be unlocked using conventional multi-factor authentication. The individual can then verify their identity by proving that they own their private key.

Mobile authentication services like the GSMA’s Mobile Connect are an ideal framework for supporting such wallets. To put it simply, mobile authentication ensures the person attempting to access an account is who they say they are. Then by adding two factor authentication, the user is asked to verify their identity via their mobile phone via a pop-up challenge to enter their PIN or biometric password. This process happens whenever the user logs into their accounts, providing a very simple, convenient, and secure way of authenticating themselves and asserting their identity. The combination of Mobile Connect for administering the wallets and blockchain for administering the identity is a perfect solution to providing digital identity and in a way that is ‘conveniently secure’.

To take the nation’s financial pulse, we must go digital

To take the nation’s financial pulse, we must go digital 1

By Pete Bulley, Director of Product, Aire

The last six months have brought the precarious financial situation of many millions across the world into sharper focus than ever before. But while the figures may be unprecedented, the underlying problem is not a new one – and it requires serious attention as well as  action from lenders to solve it.

Research commissioned by Aire in February found that eight out of ten adults in the UK would be unable to cover essential monthly spending should their income drop by 20%. Since then, Covid-19 has increased the number without employment by 730,000 people between July and March, and saw 9.6 million furloughed as part of the job retention scheme.

The figures change daily but here are a few of the most significant: one in six mortgage holders had opted to take a payment holiday by June. Lenders had granted almost a million credit card payment deferrals, provided 686,500 payment holidays on personal loans, and offered 27 million interest-free overdrafts.

The pressure is growing for lenders and with no clear return to normal in sight, we are unfortunately likely to see levels of financial distress increase exponentially as we head into winter. Recent changes to the job retention scheme are signalling the start of the withdrawal of government support.

The challenge for lenders

Lenders have been embracing digital channels for years. However, we see it usually prioritised at acquisition, with customer management neglected in favour of getting new customers through the door. Once inside, even the most established of lenders are likely to fall back on manual processes when it comes to managing existing customers.

It’s different for fintechs. Unburdened by legacy systems, they’ve been able to begin with digital to offer a new generation of consumers better, more intuitive service. Most often this is digitised, mobile and seamless, and it’s spreading across sectors. While established banks and service providers are catching up — offering mobile payments and on-the-go access to accounts — this part of their service is still lagging. Nowhere is this felt harder than in customer management.

Time for a digital solution in customer management

With digital moving higher up the agenda for lenders as a result of the pandemic, many still haven’t got their customer support properly in place to meet demand. Manual outreach is still relied upon which is both heavy on resource and on time.

Lenders are also grappling with regulation. While many recognise the moral responsibility they have for their customers, they are still blind to the new tools available to help them act effectively and at scale.

In 2015, the FCA released its Fair Treatment of Customers regulations requiring that ‘consumers are provided with clear information and are kept appropriately informed before, during and after the point of sale’.

But when the individual financial situation of customers is changing daily, never has this sentiment been more important (or more difficult) for lenders to adhere to. The problem is simple: the traditional credit scoring methods relied upon by lenders are no longer dynamic enough to spot sudden financial change.

The answer lies in better, and more scalable, personalised support. But to do this, lenders need rich, real-time insight so that lenders can act effectively, as the regulator demands. It needs to be done at scale and it needs to be done with the consumer experience in mind, with convenience and trust high on the agenda.

Placing the consumer at the heart of the response

To better understand a customer, inviting them into a branch or arranging a phone call may seem the most obvious solution. However, health concerns mean few people want to see their providers face-to-face, and fewer staff are in branches, not to mention the cost and time outlay by lenders this would require.

Call centres are not the answer either. Lack of trained capacity, cost and the perceived intrusiveness of calls are all barriers. We know from our own consumer research at Aire that customers are less likely to engage directly with their lenders on the phone when they feel payment demands will be made of them.

If lenders want reliable, actionable insight that serves both their needs (and their customers) they need to look to digital.

Asking the person who knows best – the borrower

So if the opportunity lies in gathering information directly from the consumer – the solution rests with first-party data. The reasons we pioneer this approach at Aire are clear: firstly, it provides a truly holistic view of each customer to the lender, a richer picture that covers areas that traditional credit scoring often misses, including employment status and savings levels. Secondly, it offers consumers the opportunity to engage directly in the process, finally shifting the balance in credit scoring into the hands of the individual.

With the right product behind it, this can be achieved seamlessly and at scale by lenders. Pulse from Aire provides a link delivered by SMS or email to customers, encouraging them to engage with Aire’s Interactive Virtual Interview (IVI). The information gathered from the consumer is then validated by Aire to provide the genuinely holistic view of a consumer that lenders require, delivering insights that include risk of financial difficulty, validated disposable income and a measure of engagement.

No lengthy or intrusive phone calls. No manual outreach or large call centre requirements. And best of all, lenders can get started in just days and they save up to £60 a customer.

Too good to be true?

This still leaves questions. How can you trust data provided directly from consumers? What about AI bias – are the results fair? And can lenders and customers alike trust it?

To look at first-party misbehaviour or ‘gaming’, sophisticated machine-learning algorithms are used to validate responses for accuracy. Essentially, they measure responses against existing contextual data and check its plausibility.

Aire also looks at how the IVI process is completed. By looking at how people complete the interview, not just what they say, we can spot with a high degree of accuracy if people are trying to game the system.

AI bias – the system creating unfair outcomes – is tackled through governance and culture. In working towards our vision of a world where finance is truly free from bias or prejudice, we invest heavily in constructing the best model governance systems we can at Aire to ensure our models are analysed systematically before being put into use.

This process has undergone rigorous improvements to ensure our outputs are compliant by regulatory standards and also align with our own company principles on data and ethics.

That leaves the issue of encouraging consumers to be confident when speaking to financial institutions online. Part of the solution is developing a better customer experience. If the purpose of this digital engagement is to gather more information on a particular borrower, the route the borrower takes should be personal and reactive to the information they submit. The outcome and potential gain should be clear.

The right technology at the right time?

What is clear is that in Covid-19, and the resulting financial shockwaves, lenders face an unprecedented challenge in customer management. In innovative new data in the form of first-party data, harnessed ethically, they may just have an unprecedented solution.

The Future of Software Supply Chain Security: A focus on open source management

The Future of Software Supply Chain Security: A focus on open source management 2

By Emile Monette, Director of Value Chain Security at Synopsys

Software Supply Chain Security: change is needed

Attacks on the Software Supply Chain (SSC) have increased exponentially, fueled at least in part by the widespread adoption of open source software, as well as organisations’ insufficient knowledge of their software content and resultant limited ability to conduct robust risk management. As a result, the SSC remains an inviting target for would-be attackers. It has become clear that changes in how we collectively secure our supply chains are required to raise the cost, and lower the impact, of attacks on the SSC.

A report by Atlantic Council found that “115 instances, going back a decade, of publicly reported attacks on the SSC or disclosure of high-impact vulnerabilities likely to be exploited” in cyber-attacks were implemented by affecting aspects of the SSC. The report highlights a number of alarming trends in the security of the SSC, including a rise in the hijacking of software updates, attacks by state actors, and open source compromises.

This article explores the use of open source software – a primary foundation of almost all modern software – due to its growing prominence, and more importantly, its associated security risks. Poorly managed open source software exposes the user to a number of security risks as it provides affordable vectors to potential attackers allowing them to launch attacks on a variety of entities—including governments, multinational corporations, and even the small to medium-sized companies that comprise the global technology supply chain, individual consumers, and every other user of technology.

The risks of open source software for supply chain security

The 2020 Open Source Security and Risk Analysis (OSSRA) report states that “If your organisation builds or simply uses software, you can assume that software will contain open source. Whether you are a member of an IT, development, operations, or security team, if you don’t have policies in place for identifying and patching known issues with the open source components you’re using, you’re not doing your job.”

Open source code now creates the basic infrastructure of most commercial software which supports enterprise systems and networks, thus providing the foundation of almost every software application used across all industries worldwide. Therefore, the need to identify, track and manage open source code components and libraries has risen tremendously.

License identification, patching vulnerabilities and introducing policies addressing outdated open source packages are now all crucial for responsible open source use. However, the use of open source software itself is not the issue. Because many software engineers ‘reuse’ code components when they are creating software (this is in fact a widely acknowledged best practice for software engineering), the risk of those components becoming out of date has grown. It is the use of unpatched and otherwise poorly managed open source software that is really what is putting organizations at risk.

The 2020 OSSRA report also reveals a variety of worrying statistics regarding SSC security. For example, according to the report, it takes organisations an unacceptably long time to mitigate known vulnerabilities, with 2020 being the first year that the  Heartbleed vulnerability was not found in any commercial software analyzed for the OSSRA report. This is six years after the first public disclosure of Heartbleed – plenty of time for even the least sophisticated attackers to take advantage of the known and publicly reported vulnerability.

The report also found that 91% of the investigated codebases contained components that were over four years out of date or had no developments made in the last two years, putting these components at a higher risk of vulnerabilities. Additionally, vulnerabilities found in the audited codebases had an average age of almost 4 ½ years, with 19% of vulnerabilities being over 10 years old, and the oldest vulnerability being a whopping 22 years old. Therefore, it is clear that open source users are not adequately defending themselves against open source enabled cyberattacks. This is especially concerning as 99% of the codebases analyzed in the OSSRA report contained open source software, with 75% of these containing at least one vulnerability, and 49% containing high-risk vulnerabilities.

Mitigating open source security risks

In order to mitigate security risks when using open source components, one must know what software you’re using, and which exploits impact its vulnerabilities. One way to do this is to obtain a comprehensive bill of materials from your suppliers (also known as a “build list” or a “software bill of materials” or “SBOM”). Ideally, the SBOM should contain all the open source components, as well as the versions used, the download locations for all projects and dependencies, the libraries which the code calls to, and the libraries that those dependencies link to.

Creating and communicating policies

Modern applications contain an abundance of open source components with possible security, code quality and licensing issues. Over time, even the best of these open source components will age (and newly discovered vulnerabilities will be identified in the codebase), which will result in them at best losing intended functionality, and at worst exposing the user to cyber exploitation.

Organizations should ensure their policies address updating, licensing, vulnerability management and other risks that the use of open source can create. Clear policies outlining introduction and documentation of new open source components can improve the control of what enters the codebase and that it complies with the policies.

Prioritizing open source security efforts

Organisations should prioritise open source vulnerability mitigation efforts in relation to CVSS (Common Vulnerability Scoring System) scores and CWE (Common Weakness Enumeration) information, along with information about the availability of exploits, paying careful attention to the full life cycle of the open source component, instead of only focusing on what happens on “day zero.” Patch priorities should also be in-line with the business importance of the asset patched, the risk of exploitation and the criticality of the asset. Similarly, organizations must consider using sources outside of the CVSS and CWE information, many of which provide early notification of vulnerabilities, and in particular, choosing one that delivers technical details, upgrade and patch guidance, as well as security insights. Lastly, it is important for organisations to monitor for new threats for the entire time their applications remain in service.

On the Frontlines of Fraud: Tactics for Merchants to Protect Their Businesses 3

By Nicole Jass, Senior Vice President of Small Business and Fraud Products at FIS

Fraud isn’t new, but the new realities brought by COVID-19 for merchants, and the rising tide of attacks have changed the way we need to approach the fight. Even before the pandemic broke out earlier this year, the transition to digital payments was well underway, which means fighting fraud needs a multilayered, multi-channel approach. Not only do you want to increase approval rates, you want to protect your revenue and stop fraud before it happens.

A great place to start is working with your payment partners to refresh your company’s fraud strategies with emerging top three best practices:

  1. AI-based machine learning fraud solutions helps your business stay ahead of fraud trends. Leveraging data profiles to model both “good” and “bad” behavior helps find and reduce fraud. AI-based machine learning will be increasingly essential to stay ahead of the explosive and sophisticated eCommerce fraud.
  2. Increasing capabilities around device fingerprinting and behavioral data are essential to detect fraud before it happens. While much of the user-input values can be easily manipulated to look more authentic, device fingerprinting and behavioral data are captured in the background to derive unique details from the user’s device and behavior. Bringing in more unique elements into decisioning, can help authenticate the users and determine the validity of the transactions.
  3. Prioritize user authentication. User authentication is a vital linchpin in any fraud defense and should receive even greater priority today. Setting strong password requirements and implementing multi-factor authentication helps curb fraud attacks from account takeover.

As well as working with your payment partners it’s more critical than ever to protect online transactions while not jeopardizing legitimate purchases. Fortunately, there are a few things you can do right now to address these concerns:

  1. Monitor warning signs

Payment verification is an important part of protecting your business. There are a variety of strategies to employ including implementing technology utilizing artificial intelligence and machine learning to help catch certain patterns. In addition to technology, here are a few other tips that may serve as warning signs. These are not a guarantee fraud is occurring, but they are flags to investigate.

o   The shipping address and billing address differ

o   Multiple orders of the same item

o   Unusually large orders

o   Multiple orders to the same address with different cards

o   Unexpected international orders

  1. Require identity verification

Finding a balance between protection and ease of purchase will ultimately help you protect your customers and your business. The following tactics can make it more difficult for fraudsters to be successful:

o   For customers that have a login, require a minimum of eight characters as well as the use of special characters in your customers’ passwords

o   Set up Two-Factor Authentication that requires a One-time Passcode (OTP) via SMS or email

o   Use biometric authentication for mobile purchases or logins

  1. Monitor chargebacks

Keeping good records is essential for eCommerce. If a customer initiates a dispute, your only available recourse is to provide proof that the order was fulfilled. Be prepared to provide all the supporting information about a disputed transaction. Worldpay’s Disputes solutions can connect to your CRM and provide you dual-layer protection against friendly fraud, first deflecting them before they arise and then fully managing chargeback defenses on your behalf.

  1. Monitor declines

Credit card issuers mitigate fraud by automatically declining payments that look suspicious, based on unusual card activity such as drastic changes in spending patterns or uncommon geolocations of spending. You can check your own declined payment history to help spot a potential problem. When volumes increase, the help of a payments fraud management partner is beneficial.

  1. Protect your own wallet

While you take the steps to protect your business, it’s also important to be mindful of your own protection—it’s incumbent on all responsible consumers to be vigilant about their data. Whether it’s simple awareness of how the fraudsters are operating today, sticking to trusted brands when shopping online, and thinking twice about what data you share and who you share it with, you’ll soon see how often you are sharing personal information about yourself.
