Abstract: A combination includes a user-portable computing device, and an identity selector adapted for interoperable use with the user device. The user computing device includes a security token service that issues security tokens in reference to a portfolio of user identities stored as information cards on the user device. The issuance of security tokens employs user attribute information that is stored onboard the user device. The identity selector exports the information cards from the user device and determines which user identity satisfies a security policy promulgated by a relying party as part of an authentication process within the context of an online interaction. The identity selector generates a token request based on one of the eligible user identities, and forwards the token request to the user device to invoke the token issuance operation. The identity selector presents the issued security token to the relying party to comply with the security policy.

Abstract: Systems and methods for dynamic and risk-aware network security are described. In one embodiment, a system dynamically assesses whether a connection over a communications medium (102) is anomalous (suspicious, malicious, deviating from normal behavior, fits a certain profile or pattern, or has the potential to be any one of these) and generates an appropriate response depending on whether the connection is deemed to be normal or anomalous for a specified period of time. The types of responses include, but are not limited to, blocking the source of the connection from connecting to its intended destination, altering the destination of the connection, auditing the connection, or any combination of these.
