ahsxn / Shannon-Fano-algorithm-and-randomisation-strategies-determining-privacy-strength

Implementation of the Shannon-Fano algorithm and randomisation strategies to determine privacy strength.

This was part of the Information Engineering Module: Semester 1.

There were 2 tasks:

Question 1: Implement the Shannon-Fano algorithm to compress and decompress a given string. Output the result of the compressed and decompressed value to individual text files.

output:
- histogram with the probability and occurrence of each character of the the given string
- encoded value of the given string using Shannon-Fano  coding
- decoded value of the encoded string

Question 2: Using the concept of mutual information, implement two randomisation strategies (uniformed and un-uniformed) to determine their privacy strength (information gain).

output:
- Implementation of 2 randomisation strategies successfully to determine the most efficient algorithm to use for privacy strength.
