As adoption of biometric authentication increases, it’s important to understand the security methods used to protect biometric data, writes GREG SARRAIL, VP of Solutions Business Development at Biometrics at HID Global.
Biometric solutions are rapidly becoming the new standard for providing secure and convenient identity verification for consumers and corporations. In recent years, biometric technologies have been adopted to enhance security on mobile devices, secure access to facilities and even validate individual identity within the banking industry. When faced with new technology, many people question the security of the solution. Where does the biometric data reside? Is it protected? Can it be easily accessed? If the data is compromised, can it be used maliciously?
Protect and/or render useless
Biometric fingerprint data is the information that is obtained by capturing unique features from an individual fingerprint image. There are several ways to protect this information to ensure that it cannot be openly accessed and used for fraudulent means. During user authentication, the biometric data collected by the sensor must match the information that was captured during enrolment and is stored on a back-end system. Most biometric systems use templates, mathematical representations of biometric data, rather than a raw image of a fingerprint. Templates are much smaller than full images, which decreases the time required to provide a match, minimizes storage requirements and protects user privacy because a fingerprint image cannot be reconstructed from a template. Some systems provide an additional layer of security by encrypting the transport tunnel and even the templates themselves to ensure the data is protected as it moves from the sensor to the back-end system.
Additional security methods can be deployed which are more dependent on the specific use case. For example, in an ATM setting, a user’s biometric information can be augmented before it is stored in a uniform way. This security practice is called “salting” and is done by combining the individual’s PIN and the fingerprint data prior to being stored. When verifying the biometric information, the same PIN is used with the same salting algorithm to provide a match. The advantage of this approach is that the back-end database does not contain an image of a fingerprint or even a standard template, but rather the combined “salted” template. This approach increases both the security and privacy of a system.
An alternate approach is to eliminate the back-end database altogether by placing the secured biometric information on a card that is carried by the user. The new South African National ID, for example, is an identity card that securely stores an individual’s unique biometric fingerprint information that was captured during the enrolment process and was written to the card. This card is then presented at the time of verification. After the individual places a finger on the sensor the information is matched locally against the data stored on the card. No database must be queried; the transaction simply confirms that the identity of the user matches the identity stored on the card. This approach reduces the reliance on the back-end database and external transmission security.
Biometrics is the measurement of physiological characteristics; characteristics that are unique to each individual. Facial characteristics are plainly available — this is how people recognize each other, after all — and fingerprints are left behind at every restaurant, subway rail or door that we touch. A secure system must ensure that an individual, and only that individual, can use his or her own biometric data to authenticate. Thus, it is not enough to simply match biometric characteristics against enrolled data, since access to your fingerprint information isn’t protected. A secure fingerprint system will evaluate whether the finger being presented is real or simply a falsified representation of actual fingerprint data. This capability is called liveness detection and it provides an important way to secure biometric information. Liveness detection reduces the ability for a fraudster to use a fake finger or replay stolen biometric data since the data is useless without a live finger. Whichever combination of security methods are used to secure your identity, the ultimate goal is to render biometric data useless if a perpetrator were to access it.
Verify, not identify
In the non-criminal setting, biometrics is typically used to verify an individual and not to identify an individual. To verify a person’s identity the goal is to confirm with the highest level of assurance that the person is who he or she claims to be. Commercial applications often use demographic information, account numbers, card numbers or digital certificates in addition to the fingerprint data to determine a match.
Criminal systems typically don’t have any other information aside from the fingerprint, or partial fingerprint, and therefore must determine an identity with only the biometric data. This process utilizes a large back-end database to compare individual unique features of a fingerprint and to find probable matches among a stored database of fingerprint templates. This process is time intensive and expensive and is not often used in a commercial setting.
Biometric security systems are as unique as fingerprints. Yet, good biometric systems combine the use of fingerprint templates with liveness detection to validate the identity of the right individual. Successful biometric systems are designed in accordance with the specific use case and with the desired results in mind: secure, convenient and reliable authentication that properly verifies the right individuals and rejects the wrong.
Huawei Mate 20 unveils ‘higher intelligence’
The new Mate 20 series, launching in South Africa today, includes a 7.2″ handset, and promises improved AI.
Huawei Consumer Business Group today launches the Huawei Mate 20 Series in South Africa.
The phones are powered by Huawei’s densest and highest performing system on chip (SoC) to date, the Kirin 980. Manufactured with the 7nm process, incorporating the Cortex-A76-based CPU and Mali-G76 GPU, the SoC offers improved performance and, according to Huawei, “an unprecedented smooth user experience”.
The new 40W Huawei SuperCharge, 15W Huawei Wireless Quick Charge, and large batteries work in tandem to provide users with improved battery life. A Matrix Camera System includes a Leica Ultra Wide Angle Lens that lets users see both wider and closer, with a new macro distance capability. The camera system adopts a Four-Point Design that gives the device a distinct visual identity.
The Mate 20 Series is available in 6.53-inch, 6.39-inch and 7.2-inch sizes, across four devices: Huawei Mate 20, Mate 20 Pro, Mate 20 X and Porsche Design Huawei Mate 20 RS. They ship with the customisable Android P-based EMUI 9 operating system.
“Smartphones are an important entrance to the digital world,” said Richard Yu, CEO of Huawei Consumer BG, at the global launch in London last week. “The Huawei Mate 20 Series is designed to be the best ‘mate’ of consumers, accompanying and empowering them to enjoy a richer, more fulfilled life with their higher intelligence, unparalleled battery lives and powerful camera performance.”
The SoC fits 6.9 billion transistors within a die the size of a fingernail. Compared to Kirin 970, the latest chipset is equipped with a CPU that is claimed to be 75 percent more powerful, a GPU that is 46 percent more powerful and an NPU (neural processing unit) that is 226 percent more powerful. The efficiency of the components has also been elevated: the CPU is claimed to be 58 percent more efficient, the GPU 178 percent more efficient, and the NPU 182 percent more efficient. The Kirin 980 is the world’s first commercial SoC to use the Cortex-A76-based cores.
Huawei has designed a three-tier architecture that consists of two ultra-large cores, two large cores and four small cores. This allows the CPU to allocate the optimal amount of resources to heavy, medium and light tasks for greater efficiency, improving the performance of the SoC while enhancing battery life. The Kirin 980 is also the industry’s first SoC to be equipped with Dual-NPU, giving it higher On-Device AI processing capability to support AI applications.

Epic Games brings a
Nite-mare to Android
Epic Games’ decision to not publish games through Google Play inadvertently opens a market to Android virus makers, writes BRYAN TURNER.
Epic Games, the creator of Fortnite, decided to take the high road by skipping Google Play’s app distribution market and placing a third-party installer for its games on its website. While this is technically fine, it is not recommended for the average user, because allowing third-party installers on one’s smartphone opens up the possibility of non-signed and malicious software to be run on the smartphone.
In June, malware researchers at ESET warned Android gamers that malicious fake versions of the Fortnite app had been created to steal personal information or damage smartphones. A malware researcher demonstrated how the fake applications works in the Tweet below.

While the decision to bypass Google Play was a bold move on Epic Games’ part, it has been a long time coming for app developers to move their premium apps off Google’s Play Store. The two major app distributors, Google Play and Apple’s App Store, take a 30% cut of every purchase made through their app distribution platforms.
The App Store is currently the only way to get apps on a non-modified iOS device, which is why Epic Games had no choice for Fortnite to be in the App Store. On the other hand, Android phones can install packages downloaded through the browser, which makes the Play Store almost unnecessary for the gaming company.
The most interesting part of this development is that Google is not the “bad guy” and Epic Games is no saviour to other game developers. Epic Games is a company with a multi-billion dollar valuation and has resources like large-scale servers to distribute and update its games, a big marketing budget to ensure everyone knows how to get its games, and server security to protect against malware.
Resources of this scale allow the game company to turn a cold shoulder to Google’s Play Store distribution and focus on its own, in-house solution.
That said, installing packages without the Google Play Store must be done carefully, and it is essential to do homework on where a package is downloaded. Moreover, when a package is installed outside of the Google Play Store, a security switch to block the installation of third party apps must be turned off. This switch should be turned back on immediately after the third party package is installed.
This complex amount of steps makes it less worthwhile to install third party apps, in favour of rather waiting for them to reach the Play Store.
From a consumer perspective, ESET recommends not installing packages outside of the Google Play Store and to ignore advertisements to download the game from other sources.
