Author and technical reviewer

Can Balkaya, CTO

Can Balkaya is CTO at Gifi. He reviews the technical explainers about text watermarking, file metadata, provenance credentials, and the limits of what Gifi can verify.

What he reviews

The articles separate three different surfaces: statistical patterns in ordinary words, invisible Unicode that can be named and deleted, and metadata such as C2PA, EXIF, XMP, PDF properties, and Office package data. Each surface needs a different verification method.

Can also reviews the implementation-backed claims about supported formats, lossless image handling, structural PDF cleaning, and what Gifi refuses to certify about private third-party detectors.
