Abstract
In a system which realizes to prevent leakage/loss of secret information by prohibiting a write operation to a secondary storage apparatus and a write operation to an external medium, an automatic collection of secret data to a server is executed, an existing application mode of PC is not damaged, and then an update of OS and an application is executed. The present invention places a secondary storage apparatus write control driver on the lower level than a file system, and redirects a write operation to the secondary storage apparatus, setting up a memory to be a primary cache, and cache data file on a cache server of a network destination to be a secondary cache. Thereby, the write operation to the secondary storage apparatus is not executed, and difference data is stored on the cache server, so that the automatic collection of secret data to the server can be realized.
