Wearable devices and data security: maximize the likelihood of success

0 21

Wearable devices are one of the most innovative product categories today. As the name implies, they are intended to be used persistently by their owners, mainly during waking hours (although sleep quality monitoring is a capacity promoted by some devices). Therefore, as expected, the information that both collects from and reports to their owners is very personal in nature. Below are Best Wearable devices you can buy

The commonly identified wearable product categories include the following:

They are designed to be used in addition to the increasingly ubiquitous smartphones and tablets, sometimes autonomously, but often in combination with state-of-the-art mobile electronic devices. As such, they are able to take advantage of existing computing, storage, and Internet connectivity facilities in the connected portable device.  They are small in size and weight.

The band is a combination of activity tracker and smartwatch. The first thing you will notice is that it is enhanced, full-color LCD touchscreen with 320 x 106 pixels of 1.4 “(245 pixels per inch). On one side of the LCD is a microphone and a combination of visible light and ambient UV sensor integrated into the band, and intended to be supported against the wrist, is an optical impulse speed monitoring sensor that employs photoplethysmography (PPG) techniques. LCD, there is a magnetic charging connector, and surrounding both, destined to confirm the correct location of wear of the band on the wrist and assess the state of the user’s perspiration, there are galvanic response sensors of the skin.

The other capacities of the band require a disassembly in order to verify them. Connectivity to a device based on an android, ions or Windows phone comes from a Bluetooth capacity 4.0 transceiver. The movement and orientation are determined by the combination of a gyro meter and a three-axis accelerometer. The location data (and the additional movement and direction) are determined by an integrated GPS receiver; this aspect of hardware design is quite unique since most other wearable devices rely on GPS installations.

Wearable Devices alternatives

A barometric sensor added to the second generation band, allows various functions related to climate, but also supports the determination of absolute elevation at any point in time and the speed of rising or fall in time.

Some wearable devices, such as the Google Glass headset, include image sensors for capturing photos and videos, as well as the display of augmented reality information and image analysis and response for other purposes.
Some Android have smartwatches include Wi-Fi transceivers as an alternative means (beyond Bluetooth) to connect to mobile devices. And the 2nd edition of the LG urban clock surpasses them all with an integrated LTE cellular data modem.


  • The possibility of an information security breach obviously starts in the wearable device itself. Fortunately, many physical connections of the wearable devices are restricted to load capacities only, versus enabling a larger data transfer support (and some even renounce the power transfer ports in favor of a support for the so-called wireless charging). However, the inherent portability of a product that can be removed from the wrist or head increases the likelihood that a hacker will have easy access to it.
  • Although it may be difficult to imagine that someone disassembles a device and explore its non-volatile memory to retrieve the stored data, such a scenario is not completely outside the sphere of possibility. Therefore, for the maximum possible defense of data, encryption should be considered as a key part of the local data storage and retrieval approach. For devices that perform data transfer via Bluetooth, the “detectable” default persistent mode is not recommended; instead, it should make the device only detectable during the “pairing” process.

In addition, Said by Lets tango Gadget Expert when pairing a wearable with a new portable device, you must automatically erase the data stored locally in the wearable device so that a hacker does not have access to the information of a previous valid user. Do everything possible to avoid “jailbreaking”, a technique often intentionally carried out by the owners in order to extend the capabilities of the devices above those normally supported by the manufacturer.
