Abstract: Systems and methods for monitoring the physical proximity of beacon devices relative to a deployment of relay devices. Beacon device may broadcast a proximate data signal receivable relay devices within range. Upon receiving a proximate data signal from a beacon, a relay is configured to provide a corresponding notification to a monitoring server. During standard operation, a beacon device is configured to broadcast the proximate data signal at a first frequency. A beacon may include an emergency trigger, as well as possible optional emergency detection sensors. Upon detecting an emergency, a beacon device broadcasts a proximate data signal at a second frequency and/or modify the proximate data signal. The monitoring server monitors the frequency of transmission and/or content of the proximate data signals from the beacon devices and, upon detecting an emergency (or the absence of an expected proximate data signal from a beacon), may provide an emergency alert.

Abstract: Methods and systems for secure transmission of information are provided. In accordance with a method of the present invention, a client sends to a server, a request, at least one unique identifier and an encryption key. The server generates a reply to the request and identifies a mobile device (based on the at least one unique identifier) to which to send the reply. The server also encrypts the reply, using the encryption key, to thereby produce an encrypted reply. The encrypted reply is then sent from the server to the mobile device (e.g., a mobile phone). Once received by the mobile device, the encrypted reply is available for transfer (automatically or manually) from the mobile device to the client. Once provided to the client, the client can decrypt the encrypted reply using the encryption key. The decrypted reply is then available for use at (e.g., by) the client.
