Abstract:
1. A computer-implemented method of recognition of an ongoing digital relationship, comprising: receiving, at a client computing device, an identity key associated with a server, wherein the identity key includes server specific information about the server; creating a random master key; creating an attendance marker and an attendance marker identifier, wherein the attendance marker is created using the identity key, the master key, and a constant, and wherein creating an attendance marker comprises encrypting identifying information using an encryption key derived from the identity key and the master key; associating the attendance marker with the server; sending the attendance marker to the server for storing the attendance marker on the server in association with a website for which the attendance marker has been created; requesting the previously stored attendance marker from the server, wherein the attendance marker indicates that the client computing device has previously accessed the server; and authenticating the server based at least in part on the attendance marker, wherein the authenticating comprises decrypting the attendance marker.
