Abstract: The invention provides novel methods, apparatuses, and systems for securely creating, storing, and transmitting data. The invention enables data exchange between a first and second device. The second device establishes a network session with a first device. An application running on the second device requests the secure messaging service to send a set of application data to the first device via the secure network. The network application initiates a network group session and allocates a relay from the secure messaging service. The first and second device creates an initialization vector and initiates an encrypt cipher stream using the network session key and the initialization vector. The first and second device initiates a decrypt stream using the initialization vector and network session key.

Abstract: This invention includes a system and method to enable a device to determine the presence information of another device over a secure communication network. First, the device and a presence server establish a secure connection. Next, while the initial secure connection with the presence server is established, the device generates a randomly created token and provides it to the presence server. The token is used as a shared-secret by the device and the presence server to secure future presence communications over a non-secure connection. Next, without the need to again enter a password or establish a secure connection with the presence server, the device uses the shared-secret to sign, encrypt and convey presence information to the presence server over an arbitrary connection. Finally, the presence server may share the first device's presence information with another device.

Abstract: The invention includes methods and systems for establishing communication between a first device and a second device. The first device forming a data packet and appending the data packet with a unique secure hash of the second device's public key. Next, the first device authenticating with a server. Next, the first device sending the appended data packet with the unique secure hash of the second device's public key to the server with the server storing it in memory. Next, the second device connecting and identifying itself to the server. Next, the second device authenticating with the server. Next, having positively confirmed the second device's identity, the server delivering all data packets with the unique secure hash of the second device's public key to the second device. Finally, the second device decrypting the data packets using the second device's private key.

Abstract: A mobile telephone (105) with a camera feature (110) that functions as a motion detection device. The mobile telephone can include an image capture software routine (120) and a motion detection software routine (125). The image capture software routine can use the camera feature to automatically generate one or more time spaced images. The motion detection software routine can detect motion based upon differences between the time spaced images. The motion detection software routine can selectively utilize a multiple algorithms.
