Abstract: Methods, systems, and computer-readable media for secure offline transmission of a plurality of data segments from a sending device to one or more receiving devices. The sending device and the one or more receiving devices may communicate via an offline local network. A secure, encrypted container may be created at the receiving device to temporarily cache the received data segments one at a time and the encrypted storage container prevents access by one or more applications of the receiving device to data stored therein based on storage instructions from the sending device. The encrypted container may be configured to store the data segments such that less than all of the data segments are stored at the receiving device at any one time.

Abstract: This disclosure is directed to embodiments of systems and methods for containerizing files and managing policy data applied to the resulting containers. In some of the disclosed embodiments, a computing system determines that a file stored in storage medium is to be included in a container to be sent to at least one computing component associated with a device including a user interface. The computing system determines that the file is of a particular type and also determines code that can be used to access files of the particular type. The computing system combines the file and the code into the container such that container is configured to be executed by the at least one computing component so as to cause content of the file to be presented by the user interface. The computing system then sends the container to the at least one computing component.

Abstract: Described embodiments provide systems and methods for transferring a file. A sender device configured to transfer a file to a receiver device may send an identifier of the receiver device and a public key to a server via a first network. The sender device may receive, via the first network prior to disconnecting from the first network, a session token from the server. The session token and the public key may be sent to the receiver device via the first network. The sender device may detect, after receiving the session token, a peer-to-peer (P2P) wireless network established by the receiver device. The P2P wireless network may broadcast a service set identifier (SSID) with a network key encrypted using the public key. The sender device may connect, using the network key, to the P2P wireless network to transfer the file to the receiver device via the P2P wireless network.

Abstract: This disclosure is directed to embodiments of systems and methods for controlling the access to files or other data. In some of the disclosed embodiments, a computing system receives a request for access to data by a first device operated by a first user, and determines that an identity of a second user associated with the data is to be authenticated to allow access to the data by the first device. The computing system invokes an authentication process to authenticate the identity of the second user based on an input provided to a second device by the second user and, based on that authentication process, determines that the identity of the second user has been authenticated based on the first input. The computing system then provides access to the data by the first device based at least in part on authentication of the identity of the second user. The authentication process may, for example, authenticate the identity of the second user based on a biometric input provided by the second user.
