The way I see it, there are three key players when it comes to mobile data privacy and security: the OS manufacturers (Google, Apple, Microsoft); mobile app developers; and the device users themselves. Each party has a role to play but they are not equally responsible or capable of having a significant impact.
Why is this important? For one thing, smartphones are just that -- smart. With access to limitless apps, the Internet, social media, GPS, video camera, a microphone, and more -- today's mobile devices have made life much more efficient and convenient, but also less secure. With this convenience comes a responsibility to protect private user data contained on, as well as transmitted to and from the device. But where does the bulk of the responsibility fall? Let's discuss.
Manufacturers: innovation, patches, and transparency
When Apple and Google released the first smartphones back in 2007 and 2008, both companies knew that security was important and they added more security-focused functionality with each successive release. Yet, despite a continual focus on locking down the OS, in the intervening years, many exploits have been discovered and many more are sure to follow.
Late in 2013, we reached a tipping point on a global scale when smartphone shipments surpassed those of feature phones. At around the same time, we experienced two major exploits: Master Key for Android and GoToFail for Apple, both which shook the confidence of the software industry, particularly those responsible for the underlying OS technology that supports today's mobile devices. The exploits drove home the fact that Apple, Google and Microsoft must now drive greater security through innovative functionality like Apple's biometric fingerprint scanner on the iPhone 5s, by rapidly patching discovered exploits, and by making smartphone security more transparent and effective.
Developers: finding the right incentives
Mobile app development also plays a massive role in mobile data privacy. In fact, it is during the development process where the biggest impact on data security can occur. The problem is that mobile app developers have little incentive to place data security in the spotlight. The reason is simple: developers make money by selling apps and very few consumers are willing to pay for apps. Instead, people prefer free ad-supported versions, which include an ad-engine, which compensates developers based on the amount of user data that is collected.
From a security perspective, that creates a big mobile app development issue, an issue contained within the security of the app itself. Consider the recent SnapChat hack where an insecure application program interface (API) was used to collect 4.6 million user names and phone numbers. There was also the WhatsApp encryption oversight, where a static encryption key was used for storing SMS history, making it trivial for another app to export and decrypt the message log. These are pretty big oversights considering both companies are valued in the billons. If the OS manufacturers are doing their part to provide data security functionality, it is up to app developers to understand and implement this technology, making users data security a top priority.
Consumers: understanding the risks
Lastly are the device users themselves. This is where I would place the least burden for data privacy since the typical consumer is far from a data security expert. The consumer's motivation is to use the device to make life easier. Thinking about security doesn't fit into that mentality.
A reasonable expectation is for users to understand where risk lies and how to manage that risk. For example, a central problem of the app development process is that people are unwilling to purchase apps, despite the fact that a paid app without an ad-engine offers much greater protection against privacy compromise and data loss. As for problems stemming from poorly designed and easily exploited apps, the technology is already improving with app container solutions and phones with maximum security as the focus, such as the BlackPhone released at the 2014 Mobile World Congress.
There is a lot of work to be done to improve mobile data security, and no one party can do it alone. What is important is that data privacy and security remain a primary focus. As a society, we rapidly continue moving to a mobilized digital world with many amazing benefits -- let's just be sure that losing our privacy isn't one of the prices we have to pay.
