`Graphic verification` which matches a picture set by a key to a picture (hole) that a user has previously selected is in the spotlight. Dementor, (CEO Kim Min Soo), a developer of security authentication solutions, has developed a new `Graphic One Time Password (GOTP) Dimensional graphics authentication is a secondary authentication method that makes it easy for customers to distinguish whether they are fake sites or not.

Four image icons can be set as passwords. And then, drag and drop to authenticate yourself. It is a simple and easy to use security authentication method for everyone. Recently, Dimension has added security function by adding a function to create its own graphic using the direction key on the screen instead of the drag and drop method.

Recently, the Kakao bank was able to deposit money easily using KakaoTalk without using the official certificate. Customers who used the existing bank experienced the inconvenience that they had to go through several security systems including official certificates when they were using mobile or web banking transactions.

The Kakao bank provided security authentication so that it could be easily logged in with fingerprint recognition or pattern without an authorized certificate. It also provides an existing security authentication method such as OTP in addition to fingerprint recognition. Such a simple authentication method for replacing the authorized certificate and preventing the pharming damage is attracting attention again recently.

In particular, as a public authentication or other security authentication and a secondary authentication alternative, graphical authentication service is attracting much attention from financial institutions such as banks and card companies. Pharming means that even if a user accesses a normal homepage address, they are taken to a phishing site and their personal information is taken away without their knowledge. Using graphical authentication, which users can recognize only by themselves, it is easy to see if a site is fake.

In particular, there is a lot of interest in the certification of the Dementor in the field of pin technology and simple authentication, which require secure, simple yet powerful security. It is also pointed out that it can be used in all OS and browsers of web and mobile by non-active X method. The application range is very wide.

Meanwhile, it can be used for security authentication and login of mobile devices and app lock, screen protection, etc. of internet devices, remote control, network, etc., which have weak security such as IoT(Internet of Things) convergence authentication. Dimension`s graphical authentication solution is currently being used as a secondary security certification and identity verification tool by more than 200 universities, including bankers and game companies.
