Beyond Life is a secure, web-based digital will management system built using the MERN (MongoDB, Express.js, React, Node.js) stack. It empowers individuals to create digital wills, upload confidential documents, and assign fine-grained access permissions based on user attributes like “family member” or “lawyer.” The platform uses advanced cryptographic methods to ensure the confidentiality and integrity of sensitive data. Will content and attachments are encrypted with AES-256, while access is controlled using Policy-Driven Ciphertext-Policy Attribute-Based Encryption (PD-CP-ABE), ensuring that only authorized beneficiaries with matching attributes can decrypt the data. Authentication is handled via JWT (HMAC-SHA256 or RS256), and data integrity is maintained using secure hashing algorithms such as SHA-256 or SHA-3. Users can assign beneficiaries and nominate executors to trigger will execution by submitting a verified death certificate. Upon validation, the system automatically grants access to the relevant content. Optional use of ECDSA or RSA supports secure digital signatures and verification. All user actions are logged for transparency and auditability. Overall, Beyond Life delivers a scalable, tamper-resistant, and privacy-focused platform for secure, posthumous digital asset management.
