Hi! I believe data collection is essential and achievable. It needn't always be a victim. It can also be a woman or a man who is aware about what could pose a threat to women's security in general. Missing/dysfunctional street lights, lack of public transport, seemingly abandoned cars, unruly people, etc. Also I think it would help to give the user an option to describe why they feel insecure, reasons could range from bad infrastructure to emotional issues. It would help redesign, or in most cases, design the area to make it more secure and hospitable.
