Abstract: Various embodiments provide methods and computing devices configured to implement the methods for dynamically changing an ephemeral shared data set. Various embodiments provide methods and computing devices configured to implement the methods for the dynamic generation of a value that may be used to protect a communication based on the dynamically changed ephemeral shared data set. Various embodiments incorporate the assumption that trusted systems ultimately are demonstrably insecure, because such systems are penetrable and vulnerable. Various embodiments provide a digital communication system that assumes no trust among various network elements, for at least the reason that the digital environment is inherently untrustworthy.

Abstract: In one embodiment, an evolving advertising system automatically optimizes internet advertising. A data storage unit 250 may store an evolving advertisement unit 320 with an advertisement characteristic according to an initial configuration parameter. A communication interface 280 may transmit the evolving advertisement unit 320 as part of a primary website 310. A processor 220 may alter the evolving advertisement unit 320 automatically upon a trigger event by changing the advertisement characteristic to follow an automatically generated configuration parameter to optimize an advertisement performance metric.

Abstract: In many computing scenarios, an individual may choose to interact with a service in a variety of roles, and may therefore create a set of accounts respectively representing the service. However, the use of multiple accounts by the same individual may introduce considerable administrative complications (e.g., failing to update all accounts with new information results in stale and/or conflicting account information), and may reduce the efficiency and/or scalability of the service. Presented herein are techniques for enabling individuals to interact with services through various roles. Such techniques involve evaluating the individual's role determinants to identify and automatically select the individual's current role; selecting a current role profile, as a subset of the details of the individual profile that are associated with the current role, and excluding details that are not associated with the current role; and performing the service according to the current role profile of the individual.
