RMIT University from Melbourne, Australia, has developed a method to hide sensitive information about patients inside the normal data stream using steganography, the practice of embedding secret information inside a larger bit of data without noticeably affecting the size or character of the larger data.

Publication: Implementation of an anonymisation tool for clinical trials
Since we do a lot of clinical research we are constantly working trying to facilitate the easy transfer of data from one hospital to the other. In this paper we presented the integration of the CTP tool from the RSNA, used for automated anonymization of imaging data, into an existing trial database that did not support imaging. The abstract is provided below along with a link to the open access paper.
Implementation of an anonymisation tool for clinical trials using a clinical trial processor integrated with an existing trial patient data information system.

Abstract
OBJECTIVES:
To present an adapted Clinical Trial Processor (CTP) test set-up for receiving, anonymising and saving Digital Imaging and Communications in Medicine (DICOM) data using external input from the original database of an existing clinical study information system to guide the anonymisation process.
METHODS:
Two methods are presented for an adapted CTP test set-up. In the first method, images are pushed from the Picture Archiving and Communication System (PACS) using the DICOM protocol through a local network. In the second method, images are transferred through the internet using the HTTPS protocol.
RESULTS:
In total 25,000 images from 50 patients were moved from the PACS, anonymised and stored within roughly 2 h using the first method. In the second method, an average of 10 images per minute were transferred and processed over a residential connection. In both methods, no duplicated images were stored when previous images were retransferred. The anonymised images are stored in appropriate directories.
CONCLUSIONS:
The CTP can transfer and process DICOM images correctly in a very easy set-up providing a fast, secure and stable environment. The adapted CTP allows easy integration into an environment in which patient data are already included in an existing information system.

Healthcare only accounted for 1% of data breaches in 2010
Are Healthcare facilities at the highest level of protection against malicious attacks? Or are they attacked less often compared to others?
In 2010, only 1 percent of the 761 data breaches reported concerned healthcare facilities. This is determined in a security report published by Verizon that can be downloaded here.

RSNA: Informatics Education and Research
A mixed session with very different presentations on informatics.
First presentation from Leipzig, Germany about CT guided tumour ablation. A consortium of institutions developed a patient specific liver tumor ablation simulation. Clinical evaluation still has to be performed.
Next two presentations by our group from Groningen, the Netherlands on the use of the RSNA informatics tools in clinical studies and anonymization tools. One of these were also highlighted by AuntMinnie. Both studies show how to accurately implement anonymization into clinical setting.
Presentation four by a group from Baltimore, USA covered AIM and RadLex which should take care of standardization in clincal radiology reporting. Image base annotations are used to enable an intelligent atlas to facilitate the review of anatomy.
Other topics included were on reporting and e-learning. See the first link on this page for all presentations and abstracts of this session.

New version of the NEN 7510 available
A new version of the NEN 7510 standard of the Dutch standards institute (NEN) is available as of today. NEN 7510 concerns Information protection in healthcare. The new version is easier to read and contains all national and international requirements for information protection in healthcare into one single document.
