Rebecca Sorla Portnoff: Coding against sex trafficking

In an effort to catch sex traffickers, CS alumna Rebecca Sorla Portnoff (Ph.D. '17, adviser: David Wagner) creates computer codes that help identify similarities in traffickers’ online ads and find the Bitcoin accounts they use to buy the ads.  She works for THORN: Digital Defenders of Children, an organization that builds technology to fight the sexual abuse of children.  UC Berkeley News has created a video about her work.
