Abstract: An evidence monitor may monitor interactions between at least one service provider and at least one service consumer during a time period. The evidence monitor may receive negative feedback from the at least one service consumer regarding a corresponding interaction of the interactions. A reputation engine may increase a reputation score of the at least one service provider during the time period in accordance with a growth rate, as the interactions occur during the time period. The reputation engine may also decrease the reputation score of the at least one service provider in response to the negative feedback and in accordance with a negative feedback response characteristic.

Abstract: Provided personal information from a user may be determined, the provided personal information being associated with network publication thereof. A comparison of the provided personal information with password-related information may be performed. Based on the comparison, it may be determined that a risk level associated with the network publication relative to password security of at least one password associated with the password-related information exceeds a predetermined risk level. The user may be notified that the network publication of the provided personal information is associated with potential compromise of the password security of the at least one password.

Abstract: According to a general aspect, a computer-implemented method for a first user to verify an association with a second user through a secret handshake protocol includes maintaining information about a reusable identification handle for the first user, where the information about the reusable identification handle is provided by a trusted third party, maintaining information about a reusable credential for the first user, where the information about the reusable credential is provided by a trusted third party, and maintaining information about a matching reference for verifying an association with another user, where the information about the matching reference is provided by a trusted third party. Information based on the reusable identification handle and based on the reusable credential is transmitted to a potential peer. First information based on a reusable identification handle for the second user is received, and second information based on a reusable credential for the second user is received.
