Abstract

As children increasingly operate online as independent agents, online service providers have to find ways to prevent them from going into adult-only spaces. Doing this in a privacy-preserving way is non-trivial, because most service providers require proof of identity, in order to verify a users age. We suggest benefiting from a reliable 'reminiscence bump' which occurs at a predictable time in an adult's life. Much of what occurs in this bump is retained for life, and this includes a memory of famous personages. We plan to display a number of images from the person's stated-age reminiscence bump to test recognition ability. Their performance in this task should signal the adulthood of the user.

Our studies found that participants had an accuracy rate of 78\% when asked to identify famous figures from within their reminiscence bump, compared to an average rate of 48\% when presented with famous figures from periods outside their 'reminiscence bump'. We suggest ways in which this could be used as part of a privacy preserving online age assurance solution called "Nessa'".
