Hitachi Has Developed A New Technology For Anonymize Encrypted Data

 

Hitachi has developed a new technology for anomizaciju encrypted private data. So the company is trying to meet the demands of the market (especially its national, Japan) for new solutions for anomizaciju private data.

Previous solutions for anomizaciju could have been applied only to data that is not encrypted, while the new Hitachi solution includes encryption of data and execution of K-anonymization of encrypted data and to the cloud environment.

 

The technology analyzes the encrypted data, determines whether the value of the given subsets equal, determines the total number of subsets with the same values ​​and uses the aggregated data to create a tree structure. This structure reduces the possibility of loss of information by using generalizations, sets the encrypted data into smaller subsets with less similar values ​​at the lower and larger subsets with more similar values ​​to higher positions in the hierarchy.

 

The technology makes it possible to compare the encrypted data takes place at high speed, and to some extent also reduces the need for handling data in encrypted form.

Additional safety data was obtained using a different encryption key for encrypting data and anomizaciju encrypted data, which is useful if the information accidentally leaked before the process anomizacije.
