Embodiments herein provide a system and method for screening and monitoring of cardiac diseases by analyzing acquired physiological signals. Unlike state of art approaches that consider only synchronized ECG and PPG signals for cardiac health analysis and do not consider PCG which is a critical signal for CAD analysis, the system synchronously captures physiological signals such as photo plethysmograph (PPG), phonocardiogram (PCG) and electrocardiogram (ECG) from subject(s) and builds an analytical model in the cloud for analyzing heart conditions from the captured physiological signals. The system and method provides a fusion based approach of combining the captured physiological signals such as PPG, PCG and ECG along with other details such as subject clinical information, demography information and so on. The analytical model is pretrained using ECG. PPG and PCG along with metadata associated with the subject such as demography and clinical information.

A method and system that allows on-the-fly synthesis and evaluation of services a scale has been provided. The method and system provide a mechanism where the service offering and their price points are accessible in a machine format and allow themselves to be lent to synthesize new service offerings with budgetary constraints, within the parameters of the predefined time windows. The system allows both a service provider and a service consumer to use a shared screen environment for service synthesis and valuation with the service provider playing the role of navigator. The system comprises of re-routing and navigating a plurality of nodes in the service composition graphs based on specified optimization parameters as chosen by the service consumer and tuned by the service provider. The method comprises of generation of the graph and graph traversal algorithms for along with service composition nodes and their specifications.

State of the art authentication mechanisms have limitations when used by Basic Emergent User (BEU). Embodiments herein provide method and system for recognition based multi-skill-multi-sensory passwords with dynamic identification of sensor combination based on end user skill, specifically for the BEU. The method disclosed generates user profile using a task-based technique to determine skill and capability of the user associated with each of a plurality of sensory categories used for generating a multi-skill-multi-sensory password. Each of the plurality of sensory categories are graded is descending order based on user's skill and capability and user is offered to select each password entry from a particular sensor category in accordance with the identified grade in each iteration. Thus, the entropy of password generation in the context of user is split among the sensor categories. Furthermore, recognition-based out of sequence approach is used during user authentication instead of more challenging memorizing-based approach.

Embodiments herein provide a method and system for real time ROI detection in thermal face images based on a heuristic approach. The ROI of the thermal images, once detected, is then further used to detect temperature of a subject corresponding to the ROI. Unlike state of the art techniques, the heuristic approach is computationally less intensive and provides fast and accurate ROI detection even in case of occluded faces in a crowd with a single thermal image having a plurality of subject being scanned. The heuristics applied does not focus on face detection but directly on point of interest detection. Once the point of interest (ROI) is detected, it may be used for plurality of applications such as subject tracking and the like, not limited to subject or object temperature sensing since the method disclosed herein is easily implementable on low power devices.

State-of-the-art techniques hardly attempt to address controlled resource access problem in context of Basic Emergent Users (BEUs). Embodiments of the present disclosure provide a method and system for Proof of Work (POW) based protection of resources. The method includes using the POW for work done by BEUs in physical world and mapping it to digital world to generate crypto currency in terms of credit score, wherein an end user is eligible or authorized to use a resource of an entity to get a desired service if accumulated credit score is above a credit threshold. Gaining points to improve the credit score is challenging as it is based on percentage of compliance achieved by the BEU through actual work in accordance with a compliance protocol. Further, the method includes authenticating the authorized user based on a set of questions with increasing difficulty, derived based on a culture graph.

Many capacitive sensing based biosignal measurements methods exist, which are generic as they do not personalize biosignal measurement. Further, are do not provide device agnostic solutions. A method and system for capacitive touch panel based biosignal measurement is provided. The method senses a change in raw capacitance value of a capacitive touch panel. However, unlike existing methods that directly utilize the raw signal for biosignal measurements, the method disclosed derives a normalized signal by normalizing a raw signal corresponding to the change in raw capacitance of the capacitive touch panel. The normalization considers inter-relationships between a plurality of variables that affect the raw capacitance value such as a set of device specific parameters associated with the capacitive touch panel of the device, a set of ethnographic parameters, and metadata associated with the subject. Thus, method provides higher accuracy in biosignal measurement using capacitive touch panel based devices by personalizing the biosignal measurements.

State of the art viewport design approach faces challenge in addressing customization of view port design. A method and device for dynamic view port generation providing enhanced viewport usability of text messages to be displayed on screen by considering type of user and customized typeface is provided. Determining of a customized typeface is based on user's reading capability tested during initial type face set up by the device. The customization of typeface includes applying kerning spacing and glyphs adjustment to squeeze area of the displayed text, still maintaining less ambiguity during reading. For received messages to be displayed, maximum size of window for a viewport is obtained on-the-fly with a constraint of maximum or optimal number of viewports displayed at a time on device screen. NLP is applied to each message to condense text in the message such that maximum information is conveyed while displaying minimum words.

The use of gestures are increasing frequently. Normally these gestures are disconnected with each other. Therefore, various methods have been used for creating the gestural language. The existing methods for creating gestural language is difficult to learn and lacks design aesthetics. A method and system for creating aesthetic design language using a plurality of gestures is provided. The system takes in to account of aesthetics of the generated form of gestures and the user's constraints of movement&#x2014;degrees of freedom. The system is using a socio-techno system which aids the machine assisted creation of aesthetic language for gestural interactions. A grammar has also been defined for creating the gestural language based on the domain. In the final stage of the system, the grammar and the form symbols are chosen/selected/published to present the interaction language to the user.

The present disclosure addresses the technical problems faced by a basic user or an emergent user while using a smart phone. For the basic users it is difficult to identify the threat on the smartphone. A system and method for enhancing the security features of a smartphone has been provided. Initially, the system classify the user of the smartphone as the basic user or non-basic user using a series of questions. The proposed method is only applicable to the basic user archetype. The present disclosure further describes the method for simplification of an information architecture and multimodal communication of the threats on the smartphone for a basic user archetype or emergent users. Specifically, this disclosure bridges the information communication gaps between the basic archetype user and the information system by surfacing the risks and optimizing their information hierarchy.
