Knox - what it is and how it works on Samsung > 커뮤니티 카카오소프트 홈페이지 방문을 환영합니다.

Many users face the problem of personal data distribution from a smartphone or computer. Fraudsters steal photos, passwords, correspondence, contacts, bank card details and other sensitive information that the user would not want to spread.

Knox on Samsung - what it is

To protect your personal data on Samsung, it is recommended to use the built-in Knox service, which protects the information on the smartphone and prevents its distribution.

The service works by means of a mechanism of forced control of access to data. Installed applications can only get the information that is required for their full-fledged activity. With its help, games will not be able to steal bank card details or personal correspondence that contains confidential information.

The program provides encryption of confidential information in a special storage. To pay for goods or services, you can use a digital code, which is valid for exactly thirty seconds. To use this function, you need to confirm your identity using your fingerprint.

Knox on Samsung encrypts the user's biometric data, including their facial image, fingerprint and iris. If an attempt is made to hack into the cell phone, access to all encrypted data is automatically blocked.

How Knox works

Knox protects personal data using a hardware and software method. When the smartphone is assembled, DRK and DUHK cryptographic keys are created. The first kind is the root key, which serves as a confirmation that the cell phone was manufactured by Samsung. The second kind is responsible for the integrity of the device. For example, whether the battery has been replaced or whether additional devices are built into the smartphone.

Mobile processors carry out a kind of division of the smartphone into two worlds. The first is responsible for the work of applications, and the second for their security. At the same time, the first "world" cannot affect the second. If a user installs a malicious application on his device, it will not be able to harm the smartphone or steal personal data.

In addition, the latest smartphone models from Samsung have a special security processor that detects voltage and temperature changes in the phone. It protects the device from resetting the counter of failed password attempts and performs high-quality encryption of personal data in all services.

How to enable or disable the application

1. 
   
2. Open the "Settings" section.
   
3. Go to the "Biometrics and Security" tab.
