## What does «What happened in 2019» govern?

DeepNude was a desktop application that took a photograph of a clothed woman and produced an altered image. It ran on a generative adversarial network and worked on women only, because that is what it had been trained on. Its author withdrew it within days of the attention it received, stating publicly that the probability of misuse was too high. Copies circulated regardless,

which is the usual fate of withdrawn software.

## What does «Why the name stuck» govern?

Because it arrived first and was easy to say. Search demand for the word in Canada still runs at 14 000 a month, years after the application itself stopped mattering.

## What does «What changed technically» govern?

The generative adversarial networks DeepNude used have been superseded by diffusion models, which start from noise and denoise towards an image under guidance. The practical difference is quality and control: diffusion models handle varied poses and lighting that broke the 2019 approach. The other change is delivery. DeepNude was software you installed; everything in this

category now runs on someone else's servers, which moves the whole question of retention and privacy to the provider.

## What does «Where the law stands in Canada» govern?

Publishing, distributing, transmitting, selling, making available or advertising an intimate image of a person without their consent is an offence under section 162.1 of the Criminal Code of Canada, whether the image was photographed or generated. If an image of you is circulating, the reporting route is our form and StopNCII.org, which hashes the image and blocks it across

participating platforms independently of any single site.

## What does «Questions readers send us» govern?

Can you still download DeepNude?

## Can you still download DeepNude?

The original was withdrawn by its author in 2019. What circulates under the name now is other software, and much of it is malware. Was DeepNude the first tool of this kind?

## What does Canadian law say?

Regardless of the tool, the same prohibition applies to intimate imagery:

> «Publishing, distributing, making available or advertising an intimate image of a person without their consent is an offence.»
