Saigopal has a PhD in Computer Science from University of California, Davis.
In today's world, customers and service providers (e.g., Social networks, ad targeting, retail, etc.) interact in a variety of modes and channels such as browsers, apps, devices, etc. In each such interaction, users are identified using a token (possibly different token for each mode/channel). Examples of such identity tokens include cookies, app IDs etc. As the user engages more with these services, linkages are generated between tokens belonging to the same user; linkages connect multiple identity tokens together. A challenging problem is to unify the identities of a user into single connected component, to provide a unified identity view. This capability needs to extend beyond channels and create true unification of identity.Since every interaction or a transaction event contains some form of identity, a highly scalable platform is required to identify and link the identities belonging to a user as a connected component. Therefore, we built the Identity Graph platform using Spark processing engine, with a distributed version of Union-find algorithm with path compression.
