You’re not the only one tracking your fitness data

Researchers have shown how simple it is to monitor and record Bluetooth low energy signals transmitted by phones and wearable devices, allowing the user to be easily identified and tracked.

Researchers at Context Information Security have demonstrated how easy it is to monitor and record Bluetooth Low Energy signals transmitted by many mobile phones, wearable devices and iBeacons, including the iPhone and leading fitness monitors, raising concerns about privacy and confidentiality. The researchers have even developed an Android app that scans, detects and logs wearable devices.

The app can be downloaded along with a detailed blog explaining the research at: www.contextis.co.uk/resources/blog/emergence-bluetooth-low-energy

The Context findings follow recent reports that soldiers in the People’s Liberation Army of China have been warned against using wearables to restrict the possibility of cyber-security loopholes. “Many people wearing fitness devices don’t realise that they are broadcasting constantly and that these broadcasts can often be attributed to a unique device,” said Scott Lester, a senior researcher at Context.  “Using cheap hardware or a smartphone, it could be possible to identify and locate a particular device – that may belong to a celebrity, politician or senior business executive – within 100 metres in the open air. This information could be used for social engineering as part of a planned cyber attack or for physical crime by knowing peoples’ movements.”

Bluetooth Low Energy (BLE) was released in 2010 specifically for a range of new applications that rely on constantly transmitting signals without draining the battery. Like other network protocols it relies on identifying devices by their MAC addresses; but while most BLE devices have a random MAC address, Context researchers found that in most cases the MAC address doesn’t change. “My own fitness tracker has had the same MAC address since we started the investigation, even though it’s completely run out of battery once,” said Lester. Sometimes the transmitted packets also contain the device name, which may be unique, such as the ‘Garmin Vivosmart #12345678′, or even give the name of the user, such as ‘Scott’s Watch’.

BLE is also increasingly used in mobile phones and is supported by iOS 5 and later, Windows Phone 8.1, Windows 8, Android 4.3 and later, as well as the BlackBerry 10. The Bluetooth Special Interest Group (SIG) has predicted that, “By 2018, more than 90 percent of Bluetooth enabled smartphones are expected to be Smart Ready devices,” supporting BLE; while the number of Bluetooth enabled passengers cars is also predicted to grow over to 50 million by 2016.

iBeacons, which also transmit BLE packets in order to identify a location, are already used in Apple Stores to tailor notifications to visiting customers, while BA and Virgin use iBeacons with their boarding pass apps  to welcome passengers walking into the lounge with the WiFi password.   House of Fraser is also trialling iBeacons on manikins to allow customers to look at the clothes and their prices on their phones. The current model for iBeacons is that they should not be invasive; you have to be running the application already, for it to detect and respond to a beacon. But the researchers have concerns: “It doesn’t take much imagination to think of a phone manufacturer providing handsets with an iBeacon application already installed, so your phone alerts you with sales notifications when you walk past certain shops,” said Lester.

The current version 4.2 of the Bluetooth Core Specification makes it possible for BLE to implement public key encryption and keep packet sizes down, while also supporting different authentication schemes. “Many BLE devices simply can’t support authentication and many of the products we have looked at don’t implement encryption, as this would significantly reduce battery life and increase the complexity of the application,” said Lester.

“It is clear that BLE is a powerful technology, which is increasingly being put to a wide range of uses,” concludes Context’s Lester. “While the ability to detect and track devices may not present a serious risk in itself, it certainly has the potential to compromise privacy and could be part of a wider social engineering threat. It is also yet another demonstration of the lack of thought that goes into security when companies are in a rush to get new technology products to market.”

VoD cuts the cord in SA

Some 20% of South Africans who sign up for a subscription video on demand (SVOD) service such as Netflix or Showmax do so with the intention of cancelling their pay television subscription.

That’s according to GfK’s international ViewScape survey*, which this year covers Africa (South Africa, Kenya and Nigeria) for the first time.

The study—which surveyed 1,250 people representative of urban South African adults with Internet access—shows that 90% of the country’s online adults today use at least one online video service and that just over half are paying to view digital online content. The average user spends around 7 hours and two minutes a day consuming video content, with broadcast television accounting for just 42% of the time South Africans spend in front of a screen.

Consumers in South Africa spend nearly as much of their daily viewing time – 39% of the total – watching free digital video sources such as YouTube and Facebook as they do on linear television. People aged 18 to 24 years spend more than eight hours a day watching video content as they tend to spend more time with free digital video than people above their age.

Says Benjamin Ballensiefen, managing director for Sub Sahara Africa at GfK: “The media industry is experiencing a revolution as digital platforms transform viewers’ video consumption behaviour. The GfK ViewScape study is one of the first to not only examine broadcast television consumption in Kenya, Nigeria and South Africa, but also to quantify how linear and online forms of content distribution fit together in the dynamic world of video consumption.”

The study finds that just over a third of South African adults are using streaming video on demand (SVOD) services, with only 16% of SVOD users subscribing to multiple services. Around 23% use per-pay-view platforms such as DSTV Box Office, while about 10% download pirated content from the Internet. Around 82% still sometimes watch content on disc-based media.

“Linear and non-linear television both play significant roles in South Africa’s video landscape, though disruption from digital players poses a growing threat to the incumbents,” says Molemo Moahloli, general manager for media research & regional business development at GfK Sub Sahara Africa. “Among most demographics, usage of paid online content is incremental to consumption of linear television, but there are signs that younger consumers are beginning to substitute SVOD for pay-television subscriptions.”

New data rules raise business trust challenges

When the General Data Protection Regulation comes into effect on May 25th, financial services firms will face a new potential threat to their on-going challenges with building strong customer relationships, writes DARREL ORSMOND, Financial Services Industry Head at SAP Africa.

The regulation – dubbed GDPR for short – is aimed at giving European citizens control back over their personal data. Any firm that creates, stores, manages or transfers personal information of an EU citizen can be held liable under the new regulation. Non-compliance is not an option: the fines are steep, with a maximum penalty of €20-million – or nearly R300-million – for transgressors.

GDPR marks a step toward improved individual rights over large corporates and states that prevents the latter from using and abusing personal information at their discretion. Considering the prevailing trust deficit – one global EY survey found that 60% of global consumers worry about hacking of bank accounts or bank cards, and 58% worry about the amount of personal and private data organisations have about them – the new regulation comes at an opportune time. But it is almost certain to cause disruption to normal business practices when implemented, and therein lies both a threat and an opportunity.

The fundamentals of trust

GDPR is set to tamper with two fundamental factors that can have a detrimental effect on the implicit trust between financial services providers and their customers: firstly, customers will suddenly be challenged to validate that what they thought companies were already doing – storing and managing their personal data in a manner that is respectful of their privacy – is actually happening. Secondly, the outbreak of stories relating to companies mistreating customer data or exposing customers due to security breaches will increase the chances that customers now seek tangible reassurance from their providers that their data is stored correctly.

The recent news of Facebook’s indiscriminate sharing of 50 million of its members’ personal data to an outside firm has not only led to public outcry but could cost the company $2-trillion in fines should the Federal Trade Commission choose to pursue the matter to its fullest extent. The matter of trust also extends beyond personal data: in EY’s 2016 Global Consumer Banking Survey, less than a third of respondents had complete trust that their banks were being transparent about fees and charges.

This is forcing companies to reconsider their role in building and maintaining trust with its customers. In any customer relationship, much is done based on implicit trust. A personal banking customer will enjoy a measure of familiarity that often provides them with some latitude – for example when applying for access to a new service or an overdraft facility – that can save them a lot of time and energy. Under GDPR and South Africa’s POPI act, this process is drastically complicated: banks may now be obliged to obtain permission to share customer data between different business units (for example because they are part of different legal entities and have not expressly received permission). A customer may now allow banks to use their personal data in risk scoring models, but prevent them from determining whether they qualify for private banking services.

What used to happen naturally within standard banking processes may be suddenly constrained by regulation, directly affecting the bank’s relationship with its customers, as well as its ability to upsell to existing customers.

The risk of compliance

Are we moving to an overly bureaucratic world where even the simplest action is subject to a string of onerous processes? Compliance officers are already embedded within every function in a typical financial services institution, as well as at management level. Often the reporting of risk processes sits outside formal line functions and end up going straight to the board. This can have a stifling effect on innovation, with potentially negative consequences for customer service.

A typical banking environment is already creaking under the weight of close to 100 acts, which makes it difficult to take the calculated risks needed to develop and launch innovative new banking products. Entire new industries could now emerge, focusing purely on the matter of compliance and associated litigation. GDPR already requires the services of Data Protection Officers, but the growing complexity of regulatory compliance could add a swathe of new job functions and disciplines. None of this points to the type of innovation that the modern titans of business are renowned for.

A three-step plan of action

So how must banks and other financial services firms respond? I would argue there are three main elements to successfully navigating the immediate impact of the new regulations:

Firstly, ensuring that the technologies you use to secure, manage and store personal data is sufficiently robust. Modern financial services providers have a wealth of customer data at their disposal, including unstructured data from non-traditional sources such as social media. The tools they use to process and safeguard this data needs to be able to withstand the threats posed by potential data breaches and malicious attacks.

Secondly, rethinking the core organisational processes governing their interactions with customers. This includes the internal measures for setting terms and conditions, how customers are informed of their intention to use their data, and how risk is assessed. A customer applying for medical insurance will disclose deeply personal information about themselves to the insurance provider: it is imperative the insurer provides reassurance that the customer’s data will be treated respectfully and with discretion and with their express permission.

Thirdly, financial services firms need to define a core set of principles for how they treat customers and what constitutes fair treatment. This should be an extension of a broader organisational focus on treating customers fairly, and can go some way to repairing the trust deficit between the financial services industry and the customers they serve.
