Abstract
The invention relates generally to the field of content authentication, and more particularly, to a system and methods for verifying the authenticity of content output to a user. In certain preferred embodiments, the content is verified by identifying the source data of the content, distributing the content, and authenticating the distributed content. Where the content has not been changed, the system may authenticate the content using a cryptographic hash. When minor changes to the content are made, the system may use a perceptual hash to authenticate the content. Further, the system may utilize machine learning algorithms to identify patterns between the same content in, for example, multiple formats and sizes. Advantageously, the content that is uploaded to the system may be used to train machine-learning models that the system may use to authenticate content that has been converted but unmanipulated.
