Securing decrypted files in a shared environment

机译:在共享环境中保护解密的文件

摘要

A method, system and computer program product for securing decrypted files in a shared environment. A filter driver in a kernel space may be configured to control service requests to encrypted files stored in a shared area, e.g., a shared directory on a disk unit, accessible by multiple users. The filter driver may receive a service request to open an encrypted document in the shared area issued from an authorized user. Upon receiving the encrypted data, the filter driver may decrypt the encrypted data. The filter driver may subsequently store the decrypted data in a file in a non-shared area, e.g., a non-shared directory. The non-shared area may be accessible only by the authorized user that requested access to the encrypted file. By storing the decrypted data in a file in the non-shared area, a file once decrypted may be protected in a file sharing environment.
