Back in the 60s, when Spider-Man made his first appearance, the idea that you could adopt, keep and maintain a secret identity was fairly plausible. Today, not so much. But could a modern-day Peter Parker elude CCTV and DNA forensics? Or are films such as Spider-Man: Homecoming, out July 7, merely the stuff of nostalgic fantasy?

"Blood, saliva, sweat - anything remaining from a fight can be profiled. Even breath can be used. If you know Batman - whose mouth is exposed - has spent time in a room, you can seal that room and apply a chemical treatment to extract DNA."

Throw away your smartphone

"Every button you press leaves an electronic footprint. And the only way to avoid such a footprint would be to use cybercrime techniques. If Batman is hacking into state-run CCTV and disabling them, that's an offence. It would also leave a trail - right back to the Batcave."
