Pass-thoughts: Security of the Future

Even though we have come across many real and fictional biometric possibilities as a means of making our security systems fail-safe, many of the existing techniques have failed to impress. The reason being, fingerprint scans, voice recognition, and retina scans, are cumbersome, slow, and a luxury that not everyone can afford.

Now how about pass-thoughts? What is this concept in the first place? And how does it exactly work? Let’s see…

Pass-thoughts: The Concept

A recent research by the The Berkeley School of Information, University of California, has revealed that it might be possible for us to access our accounts by simply thinking of our passwords instead of typing them. Electroencephalograms (EEGs) or brainwave computer authentication shall help you access the accounts by collecting the data we imagine in our minds! The scope of converting passwords into pass-thoughts, by using relatively affordable biosensor technology, could well become our next virtual reality.

This extraordinary project was led by professor John Chuang, and his students Hamilton Nguyen, Charles Wang, and Benjamin Johnson. The findings of the research were presented at the Seventeenth International Conference on Financial Cryptography and Data Security, during the 2013 Workshop on Usable Security.

Research Using the NeuroSky MindSet Brainwave Sensor

The NeuroSky MindSet device consists of a single sensor that rests against the forehead, and was used for carrying out this research. This wireless headset looks similar to any normal Bluetooth, except that it has the added feature of EEG sensors which read the brainwave signals of the person wearing the headset. The team carried out experiments to assess whether the computer was able to distinguish between the brainwave patterns of different people, and whether the signal provided by the EEG channel was strong enough for producing a positive authentication. The team selected 15 volunteers to perform seven mental tasks, both individually and together, so that their brainwaves could be measured. These were the seven tasks:

  1. The participants were asked to visualize moving a finger up and down, while focusing on their breathing.
  2. Some were asked to respond to an audio tone, by focusing on a dot placed on a sheet of paper.
  3. They were told to make up a secret and focus on it for some time.
  4. They had to imagine replaying a specific motion from a sport of their choice.
  5. Some were asked to watch images on a screen, and count the objects of their chosen color.
  6. They were asked to imagine themselves singing a song they liked a lot.
  7. They had to focus on a specific thought for ten seconds.

The data collected from all the brainwaves sampled, provided sufficient information to authenticate each user from one another. The devices were able to read customized ‘pass-thoughts’, by reducing the error rate to less than 1%. They also found that the results gathered from individual tasks were more or less the same, as compared to the data gained from combined tasks.

The Concern

Even though this research may be a mere step towards brainwave authentication, the possibility of computers being able to recognize an individual by their specific task-oriented brainwaves seems more likely than ever before. However, unless a distinct brainwave is accepted by the computer, the current research raises some security concerns. Some have raised concerns that it would be easy to hack into someone’s mind or Internet account, if the perpetrators knew the song imagined or object/color picked, or other tasks imagined by the owner of account.

Touchscreen Technology

How Touchscreens Work
A touchscreen has 3 main components: a touch sensor, a controller, and a software driver. To make a complete touch input system, a touchscreen is combined with a display and a PC or other device.
1. Touchscreen Sensor
This is a glass plate having a touch responsive surface. The sensor is positioned over a display screen, so that the responsive area of the plate covers the maximum viewable area of the video screen. There are a number of touch sensor technologies available in the market today, each using a different approach to detect touch input. The sensor has an electric current or signal passing through it and touching the screen causes a change in the voltage or signal. This voltage or signal change is used to find out the location of the touch to the screen.
2. Controller
The controller used in a touchscreen is a small PC card that interconnects between the touch sensor and the PC. The controller takes data from the touch sensor and converts it into information that PC can understand. For integrated monitors, the controller is usually installed inside the monitor, or is placed in a plastic case for external touch add-ons/overlays. The controller is useful to determine what type of interface/connection you will need on the PC. Integrated touch monitors are provided with an extra cable connection on the back for the touchscreen. Controllers are available by connecting to a Serial/COM port (PC) or to a USB port (PC or Macintosh).
3. Software Driver
The driver is software for the PC system that permits the touchscreen and computer to work together. It tells the operating system of the computer how to interpret the touch event information that is sent from the controller. Today’s touchscreen drivers are a mouse-emulation type driver. This makes touching the screen the same as clicking your mouse at the same location on the screen. This permits the touchscreen to work with existing software and provide new applications to be developed without the need for touchscreen-specific programming. Some devices such as thin client terminals, DVD players, and specialized computer systems either do not use software drivers, or they have their own in-built drivers.
Uses of Touchscreens
Touchscreens are one of the simplest PC interfaces to use, making it the interface of choice for a large number of applications. The following are some of the uses of a touchscreen.
1. Public Information Displays
2. Retail and Restaurant Systems
3. Control and Automation Systems
4. Computer-based Training
5. Assistive Technology

What is Swype Texting?

A user no longer has to press or tap the letter on the keyboard to enter a text in the text-box, but all one has to do is, in one continuous motion slide the finger over the letters on the keyboard and the input of the words fall out instantly. In short, it’s the technology of dragging your finger from letter to letter on the keyboard to create words.

Swype Texting

The technology of Swype has been invented for about 7-8 years now, but has been implemented recently in hand-held cell phone devices and similar applications. Swype is a brand new technology introduced by Swype Inc., that runs on the idea of swiping characters (text) on the keyboard instead of specifically pressing individual letters on the keyboard. You can refer Swype to the technology of predictive texting in your cell phones, which catches the word pre-hand before you finish typing the entire word. Likewise, the key advantage of using Swype is, it expends an error-correcting algorithm plus an enhanced language model in order to predict the user’s intended word. In this case, a user has to be absolutely random and rapid while tracing a path on the keyboard and within a fraction of a second the text entry would be done! Swype is designed to give a data input of 50 word per minute (wpm), with such an easy technology, this method so far happens to be the fastest way of enabling the user to enter the text in his/her application device. These days this technology is preloaded on many cell phones like Droid XiPhoneiPadHTC and so on. It is also comfortably compatible with devices like tablets, cell phones, kiosks, game consoles, virtual screens and televisions and perhaps much much more.

So by any chance if your application device is a touchscreen having a traditional QWERTY keyboard in it, operating the technology of Swype in one continuous motion across the touchscreen will definitely be an exciting experience. Let’s take an example and see how this system functions.

Tracing a Path with Swype

Now all you have to do is slide your finger from letter ‘Q’, then lift your finger for a slightest gap to reach the letters ‘U’ and ‘I’, then again smoothly lift your finger to reach the bottom line to reach the letter ‘C’ and continuing in the same manner reach the letter ‘K’ to complete the word QUICK. The best part about tracing the path on the keyboard is a user doesn’t need to be accurate or precise while typing.

Amazing Facts About Palm Sander

This is the age of smartness and smoothness. Nowadays only good quality and long life duration are not enough because of attractiveness is another requirement. Whether you make any wooden furniture, frames or any plastic furniture or something with both components, it is one of the vital need to make them smooth and attractive. Unless bringing smoothness and attractiveness your work will be just waste of your money even that would be a reason of customer dissatisfaction.

A palm sander is the most commonly using a sander with has a variety of uses especially while you are thinking to make your wooden components more smoother and shiny. Among other benefits of the sander includes following.


Power is the main fact for a palm sander. When you operate a sander over wood, it should have the ability to compress the wood and bring a sliced part of components from the top of the wood. However different wood has different type and thickness, and your sender should have the ability to work over any kind of wood. Unless having enough capacity and power, you would fail to complete the work with perfection.


Nothing is permanent in the world, but we would try to make everything longer as we can but is difficult and almost impossible to pay for a new palm sander every time but you can avoid this cost if you can get which has flexibility. However, sander disk is the main part of sander which the only role in making your woodsmooth and attractive. The disk is the only part that you have to replace after a sudden interval or while it would be unable to deliver desired performance. It is great you don’t need to buy new palm sander every time, but you can replace the sander disk.

Advanced Features Nowadays all the latest Palm sanders are a combination of update features. With the change and technological development palm sanders faster, reliable and easy to use. However, if you compare their latest most remarkable would be the working process and dust disclosure procedures. It is amazing that you don’t have to clean the sanded dust by hands because all the recently released palm sander have an an additional hose that works to remove dust from inside and throw them to your prefix destination. However another remarkable fact of palm sander that they have multiple Speed Settings that you can choose as you need as per wood quality.
