A decentralized access-control framework that protects sensitive crowdsensing data from unauthorized use.
Fernet-encrypted off-chain storage is paired with on-chain access control, while Solidity smart contracts manage identities, ownership, permissions and audit logs immutably. Keyword-based indexed retrieval enables efficient search without exposing encrypted content, and every access request and approval is recorded on-chain.
Mobile crowdsensing collects location and sensor data from thousands of contributors, then stores it wherever the platform operator chooses. Contributors have no control over who reads it and no proof of who did.
Separate the data from the permission to read it: keep encrypted payloads off-chain, put identity, ownership and access rules on-chain, and make every access attempt part of the immutable audit trail.

Every project is quoted individually, because the price depends on the modules you need, your technology stack, your college's format and your deadline. Send us the project name on WhatsApp and we'll share a quote the same day.
Yes. Share your guide's requirements, preferred technology stack and abstract format, and we adapt the modules, dataset or UI accordingly.
That is the point of the explanation session. We walk you through the architecture, every module, the flow of data and the results, and hand over a viva question bank with answers.
We help you with setup end to end — dependencies, environment, database and configuration — over chat or a call until it runs on your machine.
Yes. Post-delivery support is included, so you can come back for fixes, doubts or demo help even after the project is delivered.
