The Progress of Keys
People use many keys/in their daily lives. For example,/students may use a key/for their locker at school. If they commute to school by bike,/they may also use a key/for their bike.
When did humans start using keys? The oldest key dates back/to ancient Egypt. The picture of a wooden key/ is painted on a wall/of the ruins there. This fact shows/that a key existed around 2000 B.C. The key was large/and was used to protect treasures. It is believed/that the key is the origin/of the current key system.
The oldest key in Japan/originated in the 7th century. A part of it/was like a shrimp’s tail. The key was used/for storehouses of wealthy people. At that time,/keys were not common/among the general public/because they did not think/that keys were necessary.
Today,/people use passwords/in addition to keys. However,/there are two problems/with passwords.
First,/people tend to use the same password/for many online accounts. A global survey showed/that 84％ of respondents used one password/for 10 to 25 different accounts. Once such a password leaks,/all accounts will be in danger.
Second,/people tend to use simple passwords. Another survey showed/that the most popular password/was “password.” It was used worldwide/by about five million people. The second most popular one/was “123456.” These passwords are easily decoded/by hackers.
A solution to the two problems/is to set a more complex password/for every account. If people were able to remember many passwords,/they would not have such problems.
There is an easier “key”/than a password. It is used in biometric authentication. In this system,/human body parts/such as a face, a fingerprint, or veins/work as a “key.” There is no risk/of losing a key/or forgetting a password.
One common type of the system/is facial recognition. It is used for smartphones and computers/as well as at airports and amusement parks. Users only need to look at a camera. It is fast and convenient.
You may think,/“I wish I could use facial recognition/for everything.” However,/there is a concern/about its accuracy. One study showed/that white men were better recognized/than black women. That was because the system did not have enough data/for some races and genders. The system needs to be accurate/for everyone.
Another issue of biometric authentication/is its security. Hackers might fake our biometric information/by using photos/of our faces or fingerprints. The faked information works/as if it were real.
In order to solve this issue,/multimodal biometric authentication has been developed. In this system,/different kinds of biometric information/are combined. For example,/both a face and a fingerprint/are used for authentication.
The main purpose of using keys/has not changed/since ancient Egypt:/to protect important things. However,/the types of keys have changed. What will be the next generation of keys?
