Deidentification and selective encryption

It is claimed that 30 percent of all data stored by 2011 will be healthcare-related. A good proportion of this will reach Cloud providers. This data, including X-Ray images and other diagnostic info, requires deidentification (removing identifying information about patients) and selective encryption.

An XML Gateway provides a high-performance selective encryption and de-identification of data, prior to sending it up to a Cloud service. In the screenshot below, you can see a Vordel XML Gateway policy which is encrypting confidential data prior to sending it up to Amazon SQS. This is done at speed, using Vordel's XML Acceleration and underlying cryptography acceleration.

The XML gateway on the client can also scan cloud-bound data for leakage of private or company-sensitive data. The data might also be encrypted, or selectively encrypted, prior to being sent up to the cloud provider. For example, an XML Gateway might ensure that data going up to a cloud computing provider is de-identified so private information cannot be associated with the data.

XML gateways, such as the Vordel XML Gateway Cloud Edition, filter traffic sent up to cloud platforms, as well as apply policies to the access to the cloud services. By doing so, XML Gateways provide the client-side on-ramp to cloud services.
