Interesting about the Dutch banking regulator and Amazon Web Services, I did not know that. Amazon has really made great strides in providing cloud services.

Cloud encryption
We should remember that if encryption of the stored data is performed in the cloud environment then "service provider is entrusted with" the encryption keys and decryption capabilities, since the keys are used in the cloud.

I found interesting projects that addressed the challenge to protect sensitive information about individuals in a way that will satisfy European Cross Border Data Security requirements.

One project included incoming source data from various European banking entities, and existing data within those systems, which would be consolidated in one European country. The project achieved targeted compliance with EU Cross Border Data Security laws, Datenschutzgesetz 2000 - DSG 2000 in Austria, and Bundesdatenschutzgesetz in Germany by using a data tokenization approach, protecting the data before sending and storing it in the cloud.

This new approach to data privacy is described in a report from the Aberdeen Group. The report revealed that "Over the last 12 months, tokenization users had 50% fewer security-related incidents (e.g., unauthorized access, data loss or data exposure than tokenization non-users". Nearly half of the respondents (47%) are currently using tokenization for something other than cardholder data.

The name of the study is "Tokenization Gets Traction". Aberdeen has also seen "a steady increase in enterprise use of tokenization as an alternative to encryption for protecting sensitive data".

Encryption gateways can be very cost effective way to keep all crypto operations, keys and tokenization operations inside your own organization.
