Professional dominatrix Madelaine Thomas is not at all your typical startup entrepreneur. Following multiple occurrences of clients distributing her intimate photographs, she felt "angry enough to do something about it" and looked to technology for a solution.
"These were striking images, I'm not ashamed of the pictures, I'm ashamed of the way that they were used against me by an individual who I don't know," explained Madelaine.
Just over a year since founding her company, Image Angel, which uses invisible forensic watermarking to identify abusers, has garnered significant recognition and was recommended as exemplary procedure in an government-commissioned study recently.
This represents quite a departure from her previous career in providing consensual sexual encounters, working with clients in the world of BDSM.
The non-consensual sharing of private images, often referred to as revenge porn, is a criminal offence with perpetrators risking two years in prison.
It is not at all an issue exclusively faced by those in the sex industry. A report indicates that approximately 1.42% of the UK female population is affected by intimate image abuse on an annual basis.
Madelaine, 37, explained victims endured feelings of humiliation. "I think a lot of people will comment, 'you shared a private image out on the internet, what do you expect?'," she said.
"I expect dignity, I expect consideration, and I expect trust, and I don't see why those are negotiable," she added. "The reality that those images could be then shared where I live or with people I love and used to hurt them, that's beyond, that's not a decision I made, that's not my mistake, that's an individual committing abuse."
Madelaine has been practicing as a professional dominatrix, mainly online, for 10 years and consistently found her work liberating and satisfying. "It's me as a dominant woman, a woman who is empowered and strong, offering my body as a treat to someone because I wish to," she said.
"People think it's strange but I view it similarly to a personal trainer or an accountant giving advice," she remarked.
She embraces being something of an anomaly in the technology sector. "I understand that it's bizarre, it's remarkable to think that an individual who was a dominatrix is now a creator of a tech company, but it took someone who has experienced it firsthand to know the flaws and the changes that were necessary," she explained.
She insisted she was not technically inclined and was managed to build her company after many sleepless nights, research and "bugging people" who know about 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 viewed by a user, it is automatically embedded with an invisible forensic watermark which is specific to that viewer.
This invisible watermark is encoded within the copy of the image itself and can withstand screenshots, being edited and being re-captured with a secondary device.
It ensures that if you find out your image has been circulated without your consent, providing the platform you used has the technology embedded, the sharer's information will be encoded in the image and can be extracted by a data recovery specialist so legal steps can follow.
To date, one platform has implemented her tech and she's in discussions with several more.
"This technology already exists in Hollywood, it is employed in live television so this is not an untested concept, it's just a novel use and a new system," said Madelaine.
"And we've tested it, we're collaborating with a company that has 30 years experience in tech development so we are confident 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 preventive measure to would-be perpetrators.
An expert from a support service said she had seen directly the trauma and guilt intimate image abuse caused for victims.
"If that self-blame is compounded by a uninformed acquaintance or professional who says 'well, why did you take those images in the first place?' that guilt can really be reinforced so it's really important that the response a victim receives is that they have committed no error," she stated.
She noted it was fantastic that Madelaine was leveraging her ordeal to bring about change, saying: "It is vital to have this multi-layered approach towards addressing 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 images of her in her underwear were shared around her town. It was the first of several incidents Jess endured in her youth that would later shape her advocacy work.
"It took so long, too long for someone to say to 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 survivors to the perpetrators. "There is no offence to willingly share an photo to someone," said Jess.
"However, it is illegal to circulate that non-consensually and I think that should invariably be where the blame is," she concluded.
