Still manually enter the password? In fact, "will be able to login to the equipment" – Sohu technology [Technews] to science news how to confirm our claimed identity, to access a variety of devices, or high alert area, at present there are a group of password, a fingerprint or iris identification using. If you want to avoid touching the screen or keyboard, then the authentication approach is necessary to change, which also prompted engineers to find new ways to identify identity, and back to the root, that is, our brains. When we do the work of the mind, as in the brain of a shape or a song to sing, our brains will produce a unique neural signal. Even if one billion people singing the same song in the brain, there will not be two as like as two peas brainwave patterns. The use of non-invasive EEG electrodes (electroencephalography, EEG) can be read and recorded these EEG signal. Each person’s unique model can be used as biometric identification, which is called the "mind password". Just think, when a person claims that he is a certain, when there is no way to go directly into the brain to prove that he is right? This kind of research has been carried out for nearly ten years, some of the equipment also has the right to development is as high as 100%, but if you want to measure so precise, it must be placed in the forehead or across the electrode head, this is really not very beautiful. Fortunately, there is a control of the computer or sleep monitoring of the ear EEG sensor has a similar effect, can be optimized to read the password. A team from the University of California at Berkeley research team, is committed to the reading of the mind password function into the earplug component of daily life. They create a set of equipment, using consumer grade single electrode EEG headset receiver, called NeuroSky Mindwave, which was supposed to be placed in the forehead electrode, has been changed into a suitable design in the ear position, only the goal is accurate. They invited the participants to test 2 groups, each group of 5 kinds of psychological operation, the brain reading accuracy has a high 72~80%, if the electrode is moved to the forehead, the accuracy is as high as 99%, so the mind password is feasible, the problem lies in how to design the most suitable place in electrode. Another challenge is the mental state of the wearer. You can sing a song that has been sung many times in the same tone, but from stress, mood, alcohol, caffeine, drugs to mental fatigue, each factor can affect the formation of the airwaves. A let subjects after strenuous exercise immediately measured EEG experiment, it shows the data with model will therefore completely change. Old fashioned "mentality" may also be a hindrance to the idea of logging in to the device. For a computer or tablet user, manually entering the password is still the most obvious way to identify the identity of the simple. But look at the future of all possible, or in the current style of wearable devices, for example, we can think about the相关的主题文章:
