Since the 1960s, various safety systems have been installed on locations where classified information is contained. With the range of simple numerical passwords to face authentication, the safety system has been considered as one of the most needed requirements in our lives.

They have constantly been more detailed and accurate along with the development of society. How far could they be developed?

About 60 years ago, computers were not common instruments since their size was extremely large and their price was significantly high to be installed in households. The only places that had computers at that time were universities and industries.

Since the number of computers was quite low compared to the number of users, a system called Compatible Time-Sharing System (CTSS) was introduced. Through the use of this system, it became possible for the users to separate their files from others in a single computer. However, since they used a fixed terminal of the main frame of the computer, users could have access to other users’ files.

In order to solve this problem, Fernando Corbató, a researcher in Massachusetts Institute of Technology (MIT) installed a system where users could set passwords for each of their files, and this system is still being used today in computers, phones, and other electronic devices.

In the 1980s, a new system of a higher security level where passwords can be changed whenever the device is used has been introduced.

When a user finds the password of another user, it was possible for him to constantly have access to the other user’s files. In order to fix this problem, One-time passwords (OTP) was introduced. OTP can change passwords in numerous ways.

The previous password can mix its order to create a new password, the password before the previous password can mix its order to create a new password, and also new passwords can be automatically created after a certain amount of time.

Today, OTP is less frequently used than numerical passwords, but it is still used in various software to increase the security level for important content.

Since 2010, along with the development of smartphone technology, the safety systems for smartphones have improved. Smartphones not only have numerical or alphabetical passwords but also have fingerprint and face authentication that have relatively greater security level.

Fingerprint and face authentication were originally introduced in large companies in order to allow only related people to enter the companies; however, today, with Touch ID and Face ID from Apple and fingerprint and face recognition option from Samsung, fingerprint and face authentication are used to only allow the user of the phone to have access.

It is possible to state that the security level for our personal information has reached the highest point. 

As such, the safety systems have been constantly developed throughout. By overcoming the limitations of the previous safety systems, they increased their security level.

It is intriguing how the new safety system would develop upon the current safety systems of the highest level.
