  4. 12. Decentralized Application Security

    Author : Per Hallgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Decentralization; Homomorphic Encryption; Location-Based Services; Privacy;

    Abstract : On the internet today, everything is centralized. For most people, a single commercial entity owns the power to disclose all their personal emails. Most commonly your emails are only disclosed to you and your correspondent, but the power to choose who sees these emails is in fact not yours. READ MORE
