Using Medical History Embedded in Biometrics Medical Card for User Identity Authentication: Data Representation by AVT Hierarchical Data Tree

Algorithm 1

Operation of the model.

Clean the data set from noise and missing values

Parse the ordered list of AVT and load them into memory

For i = level 𝑛 to level 1.

Begin-For

  (1) Compute the attributes information in level i

  (2) Feature selection, eliminate redundant attributes if any: FS(𝐷_𝑖)

  (3) Aggregate selected attributes to abstract groups: Agg(𝐷_𝑖)

  (4) Abstract attributes to a higher level: Abs(𝐷_𝑖,𝐿_𝑖)

  (5) Consume the newly transformed dataset and build a corresponding decision tree: Classifier

   (𝐿_𝑖,DT_𝑖)

  (6) Retain the performance evaluation results for visualization.

  (7) i−−
