Fujitsu has developed a new technology which can turn biometric data into a cryptographic key, in efforts to strengthen the security of encryption.

The new technology uses different randomised numbers to convert biometric data into a cryptographic key for use in encryption and decryption.

As it turns the data into cryptographic key, it ensures better protection of confidential data, preventing the unconverted biometric data from passing through the network.

It will also eliminate the use of cryptographic key management as it can securely encrypt and decrypt confidential data using biometric data.

The conventional method of using biometric data sees it being used to retrieve confidential data from cloud services, requiring the sending of biometric data through a network, which could raise security issues.

With the new technology, the confidential data is converted with an error-correcting code, with the feature code extracted from the biometric data added to generate the encrypted data. This encrypted data is then registered in the server.

The company will present the technology at the 8th International Symposium on Foundations & Practice of Security (FPS 2015), to be held in Clermont-Ferrand, France, starting from today.

Fujitsu is currently trying to speed up the decryption processing and expand the types of information that can be encrypted.

It will also examine the development of the feature code, and work to expand the types of applicable biometrics, such as fingerprint

It looks to commercialise the technology during 2017.
