New Confidential Information Management
Warifu platform service


Our Service

WARIFUYA provides the security platform using WARIFU method.
We achieved to provide it which has been used over three thousand years in the East.
Each split WARIFU file has no meaning so that no one can retrieve original data.
By using WARIFU, protection level of various data files will increase significantly.

What is “WARIFU”

WARIFU divides digital original information at the bit level using proprietary technology and restores it.
It is a technology to make it impossible to restore it to the original information with few WARIFU file.
All you have to do is generate WARIFU file and keep it in an arbitrary place.

Basic Function of “WARIFU”

1. Normal mode(completely secret sharing type)

The original file can be restored, Only when all the distributed warifu files are available.

2. Recovery mode (Threshold secret sharing type)
