Privacy-Preserving Client-Side Information Processing: A Browser-Based Architecture for Local Data Analysis and Secure File Handling
Description
This paper investigates a client-side processing architecture in which selected data-processing operations are performed locally inside a modern web browser using JavaScript, Web Workers, WebAssembly, and browser-native cryptographic interfaces without transmitting user files to application servers. Particular attention is given to document processing, image transformation, cryptographic hashing, memory management, and zero-retention security controls, with production benchmarks from Utilvo (https://utilvo.com).
