Access control is a fundamental component of security compliance programs that ensures security technology and access control policies are in place to protect confidential information, such as customer data. Most organizations have infrastructure and procedures that limit access to networks, computer systems, applications, files and sensitive data, such as personally identifiable information (PII) and intellectual property. Attribute-Based Access Control: Attribute-Based Access Control (ABAC) has recently been proposed to enforce secure access to resources in a dynamic environment. In ABAC, access decisions are based on the values of a set of attributes, each of which is a specific feature of a subject, object or environment, and a set of rules, collectively referred to as the organizational ABAC policy. ABAC considers contextual information while making an access decision. Since the access decisions are not based on the identity of the users, ABAC is suitable in scenarios where all the users are not known beforehand. This encourages, and often necessitates organizations to migrate to ABAC from their traditional access control systems. An organization intending to migrate needs an ABAC policy. The process of constructing an ABAC policy, known as policy engineering, has been identified as one of the most challenging and costliest components in implementing ABAC. My research involves algorithmic designing of ABAC policies that fulfill certain objectives. Based on the objectives there are multiple directions of research. Few of the directions are enlisted below: The constructed policy should satisfy the “Principle of least privileges”, i.e., it should not allow any unauthorized access to the organizational resources. The time required to construct an ABAC policy should be reasonable. It has been shown in the literature that the problem of constructing an ABAC policy is NP-Complete. Therefore, our objective is to design effective approximation algorithms that enable us to construct an ABAC policy in polynomial time. Another direction of research is to construct the ABAC policies in such a form that it ensures faster access decisions. This involves organizing the policies into suitable data structures. Utilization of various machine learning tools in policy engineering for ABAC. Awards & Achievements: MHRD Doctoral Scholarship (July 2015 – July 2020), MHRD, Govt. of India.

An ultra-low-powerMSP430-based embedded system and associated computational algorithm to develop a point-of-care cardiac pre-screening device

/

The system is a point-of-care (POC) device that can deliver heart-care services to the rural population and bridge the rural–urban divide in healthcare delivery.Normal heart sounds provide an indication of the general state of the heart in terms of rhythm and contractility, while changing its signature due to any cardiovascular pathology for additional murmurs that contributesignificant information in diagnosis. Eventually, the presence of lung sound affects the signature characteristics of heart sound when mixed with the later one in spatio-temporal domain, further separation of which becomes difficult through normal filtering approaches. This work aims todetermine a framework for utilization of automated HS analysissystem for community healthcare and healthcare inclusion. It focuses on the development of a standalone system using a TI-MSP430, aiming to acquire and filter the heart sound signal based on modern signal processing algorithms.Initially, the acquired sound waves are passed through a band pass filter bank followed by an amplification unit, enabling elimination of high frequency noise signals and subsequent amplification of the signal of interest. When captured at MSP430 terminal, the microcontroller converts the analog signal into its digital counterpart, maintaining Nyquist rate and stores the time-sequence data into its on-board memory blocks. The computational algorithm, based on adaptive and wavelet signal processing techniques, integrated on the hardware platform further process the acquired data to reduce the effect of lung sound from the composite signal through various statistical measures. Output of the MSP430 system can be either fed to a digital display or microphone system for accurate determination of the heart sounds which can provide diagnostic clinical inference about the heart in health and pathology.

Non-invasive andin vivo dynamic imaging of microvasculature and tissue perfusion using laserspeckle contrast technique

/

A relative measurement of blood flow changes is of major importance in the clinical domain for quantifying vascular change due to tissue injury or diseased condition. In superficial organs (viz. eye, skin), changes in blood flow are caused by different risk factors: atherosclerosis, blockage due to abnormal deposition of extracellular matrix within blood vessels, high cholesterol profile, diabetes and other inflammatory disorders like burn injury, wounds, as well as growth of benign and malignant tumours (lesions). These pathological conditions cause improper supply of oxygen and nutrients to the cells, affecting the functional and structural integrity of vasculature. In this context, Laser speckle contrast imaging (LSCI) provides a low-cost solution with high resolution probing facility among blood flow imaging modalities like: laser Doppler flowmetry, Doppler optical coherence tomography, polarization spectroscopy, photo-acoustic tomography, magnetic resonance imaging etc. This work presents speckle contrast imaging technique for in vivo imaging of microvasculature and blood perfusion in different physiological conditions. The objective is to develop computational algorithms for processing speckle images and evaluates its efficacy for quantifying changes in blood flow during abnormal state. This probing mechanism can be utilized for different applications like: detection and tracking of emboli in vascular model, changes in blood perfusion in skin flaps, changes in retinal blood perfusion due to external stimuli or various ocular pathologies, non-invasive and label free retinal angiography for the pathologies aggravating neovascularization, functional characterization of various cutaneous woundsand their stages of progression for periodic healing study etc.
