Abstract: Systems and methods for managing access to a computer account of a computer system that is not associated with a human user. The system comprises a password repository for storing a password for the computer account. The password is preferably encrypted with at least two secrets. The system also comprises a first data storage device for storing the first secret and a second data storage device for storing the second secret. The system additionally comprises a computer device in communication with the password repository and the first and second data storage devices for managing access to the computer account. The computer device is programmed to, in response to a request to perform an action under the computer account: (i) retrieve the first secret from the first data storage device; (ii) retrieve the second secret from the second data storage device; and (iii) decrypt the password with the first second secrets.

Abstract: A node is suitable for a wireless network. A wireless network comprises one or more sensor nodes and/or one or more control nodes. In the wireless network, the sensor node transmits in response to a sensed event and/or a request from a control node. A transmission/routing of data between a sensor node and/or a control node may be subject to a policy constraint and a resource constraint.
