Abstract
A method for detecting and preventing phishing phone calls through verified attribute analysis is described. The method may comprise receiving, by a receiving device, a phone call from a sending device and receiving identification data in parallel with the phone call, the identification data describing context of the phone call. The method may then identify an attribute assertion from the identification data. The attribute assertion may comprise a signed attribute of the phone call and may be signed by a trusted authority. The method may comprise determining content of the phone call, analyzing the content of the phone call against the signed attribute, and performing a defined operation based on a result of the analysis of the content against the signed attribute.
