The file f is intercepted. A filename and one or more text strings entered as searchable metadata are also intercepted. An identifier id(f) is generated for the file f. The filename, the one or more text strings, and id(f) are stored together on a content address server. A symmetric encryption key KF is generated. File f is divided into n segments. An identifier id(si) is generated for each segment si. Each si is encrypted using KF, producing n encrypted segments esi=ESKF(Si). Each esi is stored with its id(si) on a peer device. For each esi, id(si) is stored on the content address server with id(f). A public key KU2 of a second user is retrieved, KF is encrypted with KU2, producing wrapped key KW2 EAKU2(KF), and KW2 is stored on the content address server with id(f)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Searchable and secure decentralized P2P filesystem","description":"A first user saving a file f is detected.
