Nowadays, all kinds of high-tech industries have blossomed everywhere, and the traditional and modern industries are constantly colliding with each other, giving rise to the sparks of the future. Of course, in this oven of technological innovation, data security has reached an indispensable stage. Traditional data security systems basically use firewalls or virus protection, and then do a good job of detection, which are far from meeting the security needs of users.

With the global spread of WannaCry on May 12, 2017, the outbreak of this incident has brought disaster and sexual damage to the Internet all over the world. This virus is the use of known OFFICE vulnerabilities, eternal blue SMB vulnerabilities, local area network infection and other network self-replication technology, so that the virus can break out in a short time. Nowadays, the common data security encryption methods in the market are file-based transparent encryption technology. Transparent encryption technology is a kind of data encryption technology which arises at the historic moment to meet the needs of enterprise data confidentiality in recent years. The so-called transparency means that it is transparent to the user and does not feel the existence of encryption. when the user opens or edits the specified file, the system will automatically decrypt the encrypted data so that the user can see the plaintext. When saving the data, the system automatically encrypts the data and saves the ciphertext. On the other hand, people who do not have the authority can not read the confidential data, so as to achieve the effect of data confidentiality. Of course, this kind of encryption technology can not prevent this kind of virus, and if there is an exception in the process of encrypting a large file, it will directly lead to the damage of the file, and for the development of programming software and the compilation of complex drawing software, print, etc., will directly lead to abnormal software debugging, or even unable to debug. These are only the problems that users may encounter in the process of use, not to mention the data on the server, if the data on the server is transparently encrypted, if there are any anomalies in the encryption process, the consequences will be unimaginable.

Sandboxie's idea is also well known in the field of computer security. Sandboxie (English: sandbox, also translated as sandbox) is a security mechanism that provides an isolated environment for running programs. In the early days, people usually put some suspicious programs into sandboxie for testing, and then through user-defined policies to control and restrict the program's use of computer resources, such as rewriting the system registry, modifying the system environment configuration and so on. In order to ensure the safe operation of the system, find out the corresponding methods to deal with this kind of suspicious software. Therefore, sandboxie can also be understood as a reliable security environment.

The development of data security encryption technology after the process of APIHOOK application layer transparent encryption technology and file filter driver layer (kernel) encryption technology, kernel-level deep transparent encryption technology arises at the historic moment, so the technical requirements are high, involving a wide range of technical fields, extremely complex, and the development cycle is long, so there are not many domestic companies that can use this technology. SDC not only integrates sandboxie's concept, but also establishes a perfect security protection system in the application layer and driver layer, so that users are imperceptible in use, and will not affect the file or system, so that it is safe and reliable.

The main features of SDC sandboxie encryption technology:

(1) A series of in-depth kernel encryption techniques such as disk filtering, volume filtering, file filtering and network filtering are adopted, and sandboxie encryption is adopted, which has nothing to do with file types and software. Sandboxie is a container.

(2) while operating secret-related data, it does not affect the access to the public network, QQ,MSN, etc.

(3) complete secrecy, including network upload, email sending, save, copy and paste, screen capture, etc.

(4) plaintext is stored on the service, ciphertext is stored on the client, and the file upload server decrypts automatically and encrypts automatically when it arrives at the client. Plaintext on the server, reducing the dependence of business continuity on encryption software

(5) it can not only keep the data of ordinary documents and drawings confidential, but also the first choice of source code security for R & D software companies (games, communications, embedded, various BS/CS application systems).

Hidden dangers of data security are everywhere. In this "Internet +" trend of the times, enterprise data security will also be our top priority!
