Embodiments for implementing intelligent boundary delineation of a region of interest of an organism in two spatial dimensions in a computing environment by a processor. Time series data of a contrast agent in one or more regions of interest captured from multispectral image streams may be collected. One or more regions of interest having one or more perfusion patterns may be identified from the time series data. Boundaries of the one or more regions of interest may be delineated into at least two spatial dimensions, wherein the boundaries of the one or more regions of interest include one or more selected labels.

Embodiments for data anonymity by a processor. A dataset may be transformed into an anonymous dataset by applying a differential privacy operation and a clustering operation to the dataset.

Embodiments for performing self-contained, consistent data masking in a distributed computing environment by a processor. A data masking operation is performed on one or more datasets in one of a plurality of data formats such that a key of each value of each key-value pair representing a common set of columns or paths for the one or more datasets is masked.
