Detailed Description

Anonymizer This class is a multi purpose anonymizer. It can work in 2 mode:

1. dumb mode This is a dumb anonymizer implementation. All it allows user is simple operation such as: Tag based functions:

DataSet function:

All function calls actually execute the user specified request. Previous implementation were calling a general Anonymize function but traversing a std::set is O(n) operation, while a simple user specified request is O(log(n)) operation. So 'm' user interaction is O(m*log(n)) which is < O(n) complexity.

2. smart mode this mode implements the Basic Application Level Confidentiality Profile (DICOM PS 3.15-2008) In this case it is extremely important to use the same gdcm::Anonymizer class when anonymizing a FileSet. Once the gdcm::Anonymizer is destroyed its memory of known (already processed) UIDs will be lost. which will make the anonymizer behaves incorrectly for attributes such as Series UID Study UID where user want some consistancy. When attribute is Type 1 / Type 1C, a dummy generator will take in the existing value and produce a dummy value (a sha1 representation). sha1 algorithm is considered to be cryptograpgically strong (compared to md5sum) so that we meet the following two conditions:
