With the rapid development of information technology, the security of computer data has attracted more and more attention. Preventing computer data from being illegally copied and ensuring the security and confidentiality of data has become an urgent problem for enterprises and individuals.
1. Encryption technology
Encryption technology is one of the important means to protect data security. By encrypting the data, it is ensured that even if the data is illegally obtained, it cannot be decrypted and accessed without authorization. Encryption technologies include symmetric encryption and asymmetric encryption, and users can choose the appropriate encryption method according to their actual needs. In addition, transparent encryption technology can encrypt data without the user's knowledge, without affecting daily normal use, but it cannot be used normally after unauthorized outgoing, so as to effectively prevent data from being illegally copied.
2. Digital rights management
Digital rights management is a way of protecting digital content through technical means. It uses technical means to restrict users from copying, printing, editing, and other operations, so as to prevent files from being illegally copied. Digital rights management can be implemented at the operating system, file system, or application level to provide users with comprehensive data protection.
3. File permission settings
The file permission feature provided by the operating system is also an effective means of protecting data security. Users can set permissions for files, such as read-only, write-only, and execute, to protect the security of files. By setting file permissions, you can restrict users' access to and operate files and prevent data from being illegally copied.
4. Offline authorization
Offline authorization is a method of restricting a user's access to and replication of files without an internet connection. This is usually achieved through a license, which the user needs to obtain online and then use it offline. This method can effectively prevent the data from being illegally copied in the offline state.
5. Digital watermarking
Digital watermarking embeds specific information into a file and is used to identify the owner and source of the file. Even if a file is illegally copied, it can be traced back to the source of the file through a digital watermark, thus preventing the data from being illegally copied and disseminated.
6. Physical isolation
Physical isolation is one of the most direct and effective means of data copy prevention. By storing important data in a locked enclosure or security cabinet that only authorized personnel can access, unauthorized copying can be greatly reduced. In addition, using a physical lock, such as a USB lock or dongle, is also an effective way to physically isolate files, and files can only be accessed by inserting the corresponding physical lock.
7. Insight into the eye MIT system
InsightEye MIT system is a comprehensive data copy prevention solution, which realizes all-round protection of data through a series of technical means. The system has a transparent encryption function, which can encrypt sensitive data and ensure the security of data during transmission and storage. At the same time, the system also provides file outgoing control functions to strictly control the outflow of data and prevent data from being illegally leaked. In addition, the outgoing approval feature ensures that only authorized users can outsend files, further reducing the risk of data breaches. In the event of a data breach, the system's document breach tracking feature can quickly locate the source of the breach and help the organization take timely action to deal with it.
The Insight Eye MIT system also has a powerful computer monitoring function, which can monitor the use of the computer in real time, including the plugging and unplugging of USB flash drives and copy operations. By monitoring users' online behavior and chat content, the system can detect abnormal behaviors and suspicious activities in time, and carry out timely alarm and treatment. This comprehensive monitoring and protection function can greatly improve the protection of information security, ensuring that the sensitive data of enterprises and individuals is not leaked by unauthorized copying.
