STCCS: Segmented Time Controlled Count-Min Sketch
Ismail Khram, Maha Shamseddine, Wassim Itani · 2020
IoT is a concept consisting of many components powered by different techniques and technologies. However, due to computation restrictions, encryption algorithms had to be adapted, often at the expense of lower data security levels and strength. To maintain data privacy between source and sink we present in this paper a data sketching algorithm that utilizes bandwidth by providing a summary of the data to the cloud. The input data stream goes through a hashing algorithm which produces a hexadecimal representation of the data before going through the sketching algorithm. At the algorithm the data is categorized and the corresponding hash cell value updated. Note is also taken of the arrival time of the data considered anomalous to allow the manager to take corrective action if it is deduced that the periodic appearance of the information is successive in nature.
