In the publication [1] we implemented anonymization and synthetization techniques for a structured data set, which was collected during the HiGHmed Use Case Cardiology study [2]. We employed the data anonymization tool ARX [3] and the data synthetization framework ASyH [4] individually and in combination. We evaluated the utility and shortcomings of the different approaches by statistical analyses and privacy risk assessments. Data utility was assessed by computing two heart failure risk scores (Barcelona BioHF [5] and MAGGIC [6]) on the protected data sets. We observed only minimal deviations to scores from the original data set. Additionally, we performed a re-identification risk analysis and found only minor residual risks for common types of privacy threats. We could demonstrate that anonymization and synthetization methods protect privacy while retaining data utility for heart failure risk assessment. Both approaches and a combination thereof introduce only minimal deviations from the original data set over all features. While data synthesis techniques produce any number of new records, data anonymization techniques offer more formal privacy guarantees. Consequently, data synthesis on anonymized data further enhances privacy protection with little impacting data utility. We hereby share all generated data sets with the scientific community through a use and access agreement. [1] Johann TI, Otte K, Prasser F, Dieterich C: Anonymize or synthesize?

Type Analysis

Data masking tools can be segmented by type into static data masking and dynamic data masking. Static data masking involves creating a sanitized version of the original dataset that can be used for testing or analysis without exposing sensitive information. This type is particularly useful in environments where data needs to be shared with third-party vendors or used in non-production environments without compromising data privacy. The rising need to secure test data environments while ensuring data utility is driving the adoption of static data masking solutions. Furthermore, advancements in data masking techniques are enhancing the efficiency and effectiveness of static data masking tools, making them more attractive to enterprises.

Dynamic data masking, on the other hand, involves masking data in real-time as it is accessed by users. This approach is beneficial in scenarios where data needs to be protected on-the-fly as it is being used in production environments. Dynamic data masking solutions offer the advantage of providing role-based access control, where different users can access the same dataset but see different levels of data masking based on their roles and permissions.

BackgroundCurrent diagnostic tools are limited in their ability to diagnose cystic fibrosis liver disease (CFLD) as disease is often focal in nature. Magnetic resonance extracellular volume quantification (MRI ECV) in the liver may have diagnostic utility in CFLD as a more selective liver volume is assessed and can be performed using equipment readily available in clinical practice on a standard MRI protocol.MethodsHealthy volunteers (HV), CF participants with no liver disease (CF-noLD) and CF participants with cirrhosis (CF-C) aged 18 years and above had MRI ECV measured using a 3T Siemens scanner. An additional retrospective analysis was performed to calculate MRI ECV in individuals who had available images obtained using a 1.5T Siemens scanner from a previous study.Results16 individuals had MRI ECV measured using a 3T Siemens scanner. Mean (SD) MRI ECV was 0.316 (0.058) for HV (n  =  5), 0.297 (0.034) for CF-noLD (n  =  5) and 0.388 (0.067) for CF-C (n  = 6 ). Post-hoc analysis showed a significant difference between CF-noLD and CF-C (p  =  0.046). Of 18 individuals with available images using a 1.5T scanner, mean (SD) MRI ECV was 0.269 (0.048) in HV (n  =  8), 0.310 (0.037) in CF-noLD (n  =  8) and 0.362 (0.063) in CF-C (n  =  2).ConclusionsLiver MRI ECV quantification was feasible in adults with CF with no significant difference in results between 1.5T and 3T obtained images suggesting applicability across different types of MRI scanner. A higher MRI ECV was demonstrated in CF participants with cirrhosis suggesting potential utility as a diagnostic tool for those with advanced CFLD. Further evaluation in larger cohorts is warranted.
