Abstract: This project enables secure video processing, encryption, and watermark embedding, focusing on user authentication, video encryption, and decryption capabilities. Users can register, log in, and upload videos along with watermarks for processing. Using the cryptography library, each uploaded video is encrypted, and its encryption key is split using Shamir's Secret Sharing, ensuring secure key distribution and storage. The encrypted frames are stored separately for later retrieval and decryption. Decryption occurs through reassembling key shares, allowing the original video to be reconstructed, with the watermark extracted from the first frame. The application further provides options to download the decrypted video, view split frames, and explore contact and performance information pages. Employing OpenCV for video processing and secure file handling techniques, this system ensures data confidentiality and integrity through a user-friendly interface and robust back-end encryption mechanisms. The application uses secure upload and storage mechanisms for sensitive data, like key shares and encrypted frames, storing them in predefined folders. Key shares are stored separately, further protecting the decryption process from unauthorized access.

Abstract: The COVID-19 pandemic fundamentally transformed the operational landscape of U.S. Software-as-a-Service (SaaS) companies, forcing rapid adoption of remote-first product management practices. This study examines the impact of distributed product teams on software delivery timelines through a comprehensive analysis of 127 U.S.-based SaaS companies that transitioned to remote operations between March 2020 and December 2021. Using mixed-methods research combining quantitative performance metrics and qualitative interviews with product managers, this investigation reveals significant variations in delivery performance based on organizational adaptation strategies, communication frameworks, and asynchronous workflow implementations. Key findings indicate that companies implementing structured asynchronous decision-making processes experienced 23% faster feature delivery times, while organizations lacking formal remote collaboration frameworks saw 31% longer development cycles. These results contribute to the growing body of literature on distributed software development and provide actionable insights for product management practitioners navigating the post-pandemic digital workplace.

Abstract: This study explores the underlying service dimensions that determine customer satisfaction for Vistara Airlines, with particular focus on the SERVQUAL model—comprising Reliability, Assurance, Tangibles, Empathy, and Responsiveness. Analysis reveals that tangibles (such as modern aircraft, in-flight services, and physical comfort) and empathy (personalized care and attention) significantly contribute to customer satisfaction. Historically, Vistara has enjoyed a strong reputation for premium service, earning high customer satisfaction and industry accolades. However, recent developments—especially following its merger with Air India—have led to increased customer dissatisfaction, citing issues with staff responsiveness, flight reliability, and diminished service quality. While Vistara once set benchmarks in India's airline industry, the gap between customer expectations and actual service delivery has widened post-merger, indicating a decline in perceived service quality. This shift highlights the importance of maintaining service consistency and customer trust during organizational transitions.

Abstract: In today’s interconnected and hybrid work environment, global tech teams frequently face miscommunication, collaboration inefficiencies, and cultural misunderstandings—issues rooted not in technical ability, but in the absence of robust Cross-Cultural Competence (CCC). As artificial intelligence (AI) and immersive technologies evolve, new possibilities have emerged for delivering soft skills training through Virtual Reality (VR)-driven experiential simulations. This study evaluates the effectiveness of AI-powered VR simulations in developing CCC among early-career professionals working in multinational technology firms. Grounded in Kolb’s Experiential Learning Theory (ELT), Bennett’s Developmental Model of Intercultural Sensitivity (DMIS), and Bandura’s Social Cognitive Theory, this mixed-methods study investigates how AI-adaptive VR modules influence user progression along intercultural sensitivity stages. The simulations are designed to mimic high-stakes multicultural workplace scenarios—such as remote team conflict, hierarchical ambiguity, and cross-cultural negotiation—leveraging real-time emotional feedback and decision-based branching to personalize the learning journey.Participants from global tech companies underwent structured VR-based learning interventions (3+ ELT cycles) over a four-week period. Pre- and post-assessments using the Intercultural Development Inventory (IDI) and Employer-Validated Global Soft Skills Index (EGSSI) revealed statistically significant growth in CCC, especially in adaptation and empathy. Qualitative reflections and biometric engagement data also indicated higher immersion and emotional resonance compared to video- or lecture-based training. The study offers compelling evidence that AI-augmented, VR-enabled soft skills programs can bridge cultural divides more effectively than traditional methods. It positions immersive technology as not just a medium, but a transformative agent in global workforce development.
