Scientific and technological developments, according to foreign media reports, your walking posture someday may become unlocked phone password. Data61 Laboratories of the Commonwealth Scientific and Industrial Research Australia developed a prototype of a small wearable device that not only uses the kinetic energy you generate to generate electricity, but also turns your walking posture into a unique authentication method. .
Walking posture can unlock the phone's unique password?
This device can monitor how you walk to produce electricity. Since the power you produce when walking is high and low, this device can turn it into a unique "signature." Moreover, this device can also use kinetic energy capture (KEH) technology to provide backup power for various mobile devices.
"Utilizing these two technologies, we can achieve two goals at a time: powering devices and authenticating users," said Sara Khalifa, a researcher at Data61 Laboratories, in a statement.
The research team tested the device on different terrains and 20 people. Test results show that the accuracy of this device using walk posture for authentication can reach 95%. And, compared to accelerometer-based gait authentication systems, it can reduce energy consumption by 78%.
When someone deliberately imitated the user's walking posture, the device's authentication error rate rose to 13%. This means that it needs to be further refined, but the developer's development ideas are correct.
"It's safer than passwords because we can't mimic walking poses," said Dali Kafaar, director of Web61's network research department. "Because KEH technology keeps track of users Footsteps, so it can collect a lot of information about walking postures, which makes it difficult for others to imitate, or to crack like guessing passwords or PINs."
The research team is also exploring other authentication methods, such as the user's breathing pattern and how the user interacts with the device.
The ceramic nozzle has different types ,the long ceramic nozzle ,the extra long ceramic nozzle ,the large dia. Ceramic nozzle ,and also the common ceramic nozzle .When the current pass through is greater ,the tig Torch need the longer ceramic nozzle ,also the larger ceramic nozzle .We have several series of the ceramic nozzle ,the 13N ,the 10N ,the 54N,the 57N,the 14N,the 53N ,and so on ,they are suit for the tig torches .The custom can choice based on the tig torches they used .
