Posted: 28 Oct 2015 10:08 AM PDT

Instagram could offer a novel way of monitoring the drinking habits of teenagers. Using photos and text from Instagram, a team of researchers has shown that this data can not only expose patterns of underage drinking more cheaply and faster than conventional surveys, but also find new patterns, such as what alcohol brands or types are favored by different demographic groups. The researchers say they hope exposing these patterns could help develop effective intervention.

Researchers find vulnerabilities in use of certificates for Web security

The study results reveal that website administrators are providing revoked certificates, certificate authorities are not using newer processes for distributing revocations, and Web browsers are not checking whether certificates have been revoked.
