Abstract: The present disclosure provides systems and methods for authenticated control of content delivery. The method includes receiving a request for an item of content from a computing device, the request comprising a security token associated with the computing device and an identifier of a group of domains, identifying the group of domains from the identifier, and retrieving a security key associated with the group of domains. The method further includes decrypting a signature of the security token, identifying an authentication string, determining that the authentication string matches a server authentication string, and identifying characteristics of the security token. The characteristics of the security token include a confidence score. The method further includes comparing the confidence score of the security token to a threshold, determining that the confidence score does not exceed the threshold, and preventing transmission of content to the computing device.

Abstract: Systems and methods for online access credential transition are described, including receiving a first string of elements associated with a subsequent online access credential, during a credential transition period, receiving a second string of elements associated with an attempted subsequent online access credential, performing a matching operation to determine a degree of matching between the first string of elements and the second string of elements, and based on the degree of matching between the first string of elements and the second string of elements, providing online feedback, and prompting another attempted subsequent online access credential.

Abstract: The present disclosure provides a secure, user-transparent, and highly efficient content provider-specific identifier read-only cookie (“ROC”). These ROCs can be generated by the client device and encrypted with a public key of the content provider, preventing third parties from indirectly identifying matches. The ROCs can include authentication token to enable the client device to determine whether the ROC was cached or otherwise misused by a content provider or other third-party.
