LDPC Codes and Digital Forensics – A Perspective Approach
Madhusmita Mishra · IETE Journal of Research · 2019
Forensic science (or forensics) is the quisling of sciences and technologies to enquire and demonstrate facts of interest in relation to criminal or civil law. Although forensics has greatly enhanced investigators’ ability to unriddle crimes, limitations are still there to be audited in and out of the courtroom in order to avoid wrongful convictions. Definition and establishment of likelihood ratio (LR) is one of the Computational methods that can be applied in the forensic sciences to increase the efficiency and effectiveness of forensic casework. It can be quite logical to apply sum product algorithm used in the case of decoding of Low density Parity check code for calculating Log-likelihood ratio (LLR), which in turn will be more effective than LR calculation in case of more effective error analysis. This theoretical endeavor explores this effort.
