BDSM practitioner Madelaine Thomas represents not at all your average startup entrepreneur. Following multiple occurrences of individuals leaking her private explicit images, she felt "angry enough to take action" and turned to technology for answers.
"Those were striking images, I'm unapologetic of the pictures, I'm embarrassed of the manner that they were weaponized by someone who I don't know," stated Madelaine.
Little over a year since founding her venture, Image Angel, which uses invisible forensic watermarking to identify abusers, has garnered significant recognition and was recommended as best practice in an independent pornography review earlier this year.
This represents quite a departure from her previous career in offering consensual sexual encounters, dominating clients in the realms of kink and bondage.
The non-consensual sharing of private images, commonly known as image-based abuse, is a punishable crime with offenders risking two years in prison.
It is far from an issue exclusively faced by those in the sex industry. A report indicates that approximately 1.42% of the women in the UK is affected by intimate image abuse on an annual basis.
Madelaine, thirty-seven, explained survivors endured feelings of humiliation. "I think a lot of people will comment, 'you put a private image out on the internet, what do you expect?'," she said.
"I demand dignity, I expect respect, and I expect trust, and I fail to understand why those are up for debate," she added. "The reality that those images could be subsequently distributed in my community or with my loved ones and employed to cause them pain, that's unacceptable, that's not my choice, that's not an error on my part, that's an individual committing abuse."
Madelaine has been practicing as a dominatrix, mainly online, for a decade and always found her work liberating and satisfying. "I am as a dominant woman, a woman who is confident and powerful, offering my body as a treat to someone because I wish to," she said.
"Some believe it's unusual but I don't see it any differently to a personal trainer or an accountant providing a service," she remarked.
She welcomes being a unique figure in the technology sector. "I understand that it's unconventional, it's crazy to think that someone who was a dominatrix is now a founder of a tech company, but it took someone who has been through it to understand the loopholes and the changes that were necessary," she explained.
She maintained she was not technically inclined and was able to build her company after a lot of late nights, research and "bugging people" who understand tech.
Image Angel can be implemented on any digital service where people exchange photos, for instance dating apps, social networks and websites.
When an image is accessed by a viewer, it is automatically embedded with an undetectable digital marker which is specific to that viewer.
This invisible watermark is encoded within the digital file of the image itself and can withstand screen shots, being edited and being photographed with a secondary device.
It means that if you discover your image has been circulated without your consent, as long as the service you used has the system integrated, the viewer's details will be encoded in the image and can be extracted by a data recovery specialist so action can be taken.
Currently, one platform has implemented her tech and she's in discussions with several more.
"This technology already exists in the film industry, it is employed in sports broadcasting so this is not brand new technology, it's just a new application and a different framework," said Madelaine.
"We have validated it, we're partnering with a firm that has 30 years experience in developing technology so we know that this is solid and what we now need to do is deploy it widely," she continued.
She said she hoped the technology would also act as a deterrent to would-be intimate image abusers.
An advocate from a leading helpline said she had seen first-hand the panic, distress and self-blame this abuse caused for victims.
"When that guilt is reinforced by a misinformed friend or professional who says 'well, why did you take those images in the first place?' that guilt can really be reinforced so it's crucial that the support somebody is provided with is that they have committed no error," she stated.
She added it was inspiring that Madelaine was leveraging her ordeal to bring about change, saying: "It is really important to have this comprehensive strategy towards tackling technology-enabled gender-based abuse, because a single solution is going to be able to solve this problem, no one helpline, it needs to be this multi-layered response."
TV presenter Jess Davies was just 15 when photographs of her in a state of undress were circulated within her local community. It was the first of several incidents Jess experienced in her teens and 20s that would later shape her advocacy work.
"It took so long, too long for someone to tell me, 'you are not to blame' and 'that shouldn't have happened'," recalled Jess.
She too is dedicated to eliminating the shame of this crime from the victims to the perpetrators. "It isn't a crime to consensually send an photo to someone," said Jess.
"But it is a crime to distribute that without consent and I think that should always be where the responsibility is," she concluded.
