Multilevel Privacy Controlling Scheme to Protect Behavior Pattern in Smart IoT Environment

Algorithm 2

Patterns Compact Algorithm (PCA).

Input: -activity-patterns, -activity-patterns,

Output: -activity-patterns: to compact the real normal activity pattern

 (1) Sorting -activity-patterns in order of descending it represents the quantity of activity in data set ;

 (2) While -activity-patterns’ do

 (3) Attain first activity pattern in -activity-patterns

 (4) for activity pattern

 (5) Delete in -activity-patterns and -activity-patterns;

 (6) for every activity pattern in -activity-patterns do

 (7) Delete in ;

 (8) end for

 (9) end for

 (10) delete in -activity-patterns;

 (11) sorting -activity-patterns in descending order

 (12) end while;

 (13) return -activity-patterns
