Industrial Visit to SIFS INDIA
An Industrial Visit to Sherlock Institute of Forensic Science (SIFS) INDIA, New Delhi was organised by Department of Computer Science & Engineering, Dronacharya College of Engineering, Gurgaon on 3rd March 2015. Twenty students from IV and VI semester accompanied by Mr. Amar Saraswat, Assistant Professor, CSE Department went for the Industrial visit. SIFS INDIA is a leading independent private forensic science lab, registered with Government of India (MCA, Govt. of India) which provides various types of forensic services. The aim of this industrial visit was to enable students to learn about image processing techniques, and Cyber Forensics.
Ms. Sikshita, Cyber Crime Expert explained about importance of Image Processing, Forensic Science, Protection of Crime Scene, Securing and Isolating the crime scenes, different types of evidences found on a crime scene. She also described how using the image processing, we can see the difference between the actual and morphed images by viewing the changed resolution of the full or the part of the Image. She gave a demo on how the data item can be recovered and which tools are required for it.
Dr. Ranjeet Singh, CEO, SIFS INDIA explained about Image Forensics by focussing on various domains of image Forensics, such as analysis of evidences, Finger Print Analysis, Handwriting recognition. Dr. Singh described about various technical challenges for automatic indexing and retrieval of scanned documents. He also discussed about Cursive Recognition Approaches such as Document Pre-processing, which consists of noise removal, word box extraction, size normalization, Holistic matching, Featured Extraction and thinning. Dr. Singh showed the ways of obtaining fingerprints, by taking the fingerprints of one of the students. Using those fingerprints, he explained about various levels of finger prints. Level 2 studies of fingerprints included line unit, line fragment, ending, bifurcation, eye, hook and Level 3 are Pores, line shape, incipient ridges, creases, warts and scars. Further explain about Finger Print Databank, Plain Arche and Tented Arche, Radial Loop and Ulnar Loop, Plain Whorl and Composite Whorl. The Composite whorl was again divided into Central Packet Loop, Double Whorl Loop and Accidental Whorl Loop. Dr. Singh focussed on Exemplar Fingerprint, which is known to have originated from as specific source camera and Latent Fingerprint, which is lifted from an evidential Image. He also talked about Cyber forensics, cybercrimes, and various preventive measures for it.
Industrial visit was concluded by Mr. Ranjeet Singh making a discussion about the various career options related to image processing and cyber forensics. He motivated the students to start their research work in the field of image processing and the major application areas related to it. The visit proved to be very fruitful as the students learned a lot about tools used in image processing, mobile forensic investigation, voice identification. During the practical sessions, the students enthusiastically interacted with demonstrator and got their queries solved.
