  • Publication number: 20240097888
    Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

  • Patent number: 11929216
    Abstract: A button mechanism includes a button, a module, and a thin sheet spring. The thin sheet spring is in physical communication with the button and with the module. The thin sheet spring exerts a tension force on the button and the module to bias the button toward a normal position. In response to a force greater than the tension force being exerted on the button, a portion of the thin sheet stretches to enable the button to be placed in a contact position. In response to the force being removed from the button, the tension force causes the thin sheet to snap back to an original position and biases the button toward the normal position.
