Wearable devices and data security: maximize the likelihood of success


29 September 2018


Wearable devices

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.

Button Cell Battery Chart- know about it more

Did your flashlight battery run out? If yes, then it will be good if you buy a new battery for your flashlight according to the recommendation from the manufacturers. If you follow the instructions or manuals given by the manufacturer inside then you can save your device from damages and wrong type of batteries. While you are replacing the batteries make sure to check the details such as battery type, capacity, chemistry, dimensions, max pulse current, self-discharge rate, etc. It may sound complicated however it is necessary for good performance of the gadget. Here we have small tips related to battery and its safety- You must never recharge the battery with the wrong charger as well as do not charge primary batteries or it may explode and cause fires. Do not swallow the battery; keep your kids away from it. These NiMH and lithium batteries do not contain toxic metals but they are dangerous and when swallowed electrolytes will close the circuit in the body as well as cause chemical reaction which caused the ultimate death of a person. Battery types: Coin/ button cell battery: These are grouped under no- rechargeable batteries. It is common in key chains, watches, remote controls, and hearing aids. There are various chemistry types of this battery like silver oxide, alkaline, and mercury oxide. In addition, most of the manufacturer interchangeably makes use of similar labels for silver oxide and alkaline batteries. If you look at the button cell battery chart then you can find out the difference and also know about the button battery sizes. Alkaline: Alkaline coin/button cell batteries are cheap and reliable batteries. 1.5 volts is the nominal voltage of this battery but when you use this battery its voltage drops with time. The real capacity of this battery is dependent on the device cut off voltage. If it is to be used in electronic equipment where there is the requirement of the constant high voltage then the so-called capacity of this battery is low. In such gadgets the need for replacement of the battery is quick. However, if the alkaline battery is to be used in gadgets that can tolerate low battery voltage, then its so-called capacity will be larger and you need not replace batteries in them so soon. Typical labels for alkaline batteries are LR##, AG##, LR###, etc. The normal capacity of alkaline LR44 is about 110-130 mAh and it is lower than equivalent silver oxide battery. Common Shelf life for it is 5 years. Silver Oxide: These button/coin cell batteries are a well-known type of batteries. They are not very expensive and have a shelf life of about 10 or more years. They have constant voltage while an operation that is identical to the nominal voltage of the alkaline batteries. Typical labels of this battery type are SR##, SG##, SR###, etc. Typical capacity of these types of batteries ex- Silver oxide SR44 is 150-200 mAh and it is more than equivalent alkaline LR44 while less than zinc-air. Zinc Air: These are used widely in hearing aid devices. They are having slightly lesser nominal voltage (1.4 to 1.45 V) however this voltage is quite similar or higher than the alkaline batteries voltage while using. In addition to this, these batteries got the largest capacity and chemistry. Typical capacity- 600-700 mAh and it is the much larger capacity when compared to silver oxide. These batteries are not common because of different reasons, however, one of the common reasons is that they work by using air, and when electrolyte dries out, it is dead and needed to be replaced. Depending on manufacturer and model, after the protective tab of these batteries is removed, leave it for some minute in the air then use it for weeks. It has a shelf life of 4-5 years. Mercury oxide: These types of batteries are no longer in the use because of their impact on the environment. They require slightly lower voltage (~1.35V) they have good capacity. The typical capacity of battery MR44 is 180-200 mAh and it is quite similar to silver oxide SR44. If a small portion of these batteries is swallowed then it can induce vomiting. Cylindrical batteries: These are commonly used in devices such as remote control devices, key chains, bikes, electric tools, etc. Cylindrical batteries are divided into 2 groups such as- Non-rechargeable or primary batteries rechargeable or secondary batteries It is to be noted that the primary batteries must never be charges. Also, keep in mind that does not recharge batteries with NOT designed charger. The nominal voltage of the non-rechargeable cell is 1.5V regardless of whether they are alkaline or carbon-zinc batteries. These are interchangeable nit alkaline batteries that have huge capacity and they are used more than the zinc-carbon batteries. For Primary lithium batteries, nominal voltage is 3V; they have a larger capacity and are light weighted. In addition to this, they tend to be highly expensive than the zinc-carbon as well as alkaline batteries and are utilized in high power gadgets such as cameras, flashlights, etc. Secondary cells’ nominal voltage is dependent on its chemistry. These batteries are smaller and packed with enough energy but if mistreated then it may burst or explode. Hence, make sure you refer a button cell battery chart before replacing or using any batteries in your device. nickel Cadmium battery it is also referred to as NiCd batteries and they have the nominal voltage of 1.2 V. it can generate large current however it has limited capacity as well as number of charging/ discharging cycles. Nickel metal hydride- it is also referred to as NiMH batteries and it offers good capacity, low rate of self-discharge, good shelf life, etc along with reasonable rates. Lithium secondary batteries- they have a voltage ranging from 3.3-3.7V and are labeled as 3.7 or 3.6V batteries. They have a large capacity, improved safety, and a higher drain. For more information about batteries, you can refer button cell battery chart. We hope you have gained enough knowledge about batteries and their usage. Hurry up and go replace your batteries.
