After Kubiiki Pride’s 13-year-old daughter disappeared, it took 270 days for her mother to find her.
When she did, it was as an escort available to be rented out on an online classified web site.
When it comes to identifying signs of human trafficking in online sex adverts, the task for police is often no easier.
It uses machine learning to spot common patterns in suspicious ads, and then uses publicly available information from the payment method used to pay for them – bitcoin – to help identify who placed them.
To identify the authors of online sex ads, Portnoff’s tool looks at the style in which ads are written.
The work was presented at the Conference on Knowledge Discovery and Data Mining in Canada this month.
The trafficker who kidnapped Kubiiki Pride’s daughter was eventually caught and sentenced to five years in prison. »
