Let's say that ip address is something like xxx.52.114.191. Would be allowed to store into database 113.191? And let's say address is Nick Example, Some street 5, 33012 Florida, US. Would be allowed to store into database ple, eet 5, Florida?
We are having some lottery game at our website that user can try only once. The most reliable way to check if user already tried is to check ip address and home address. Since we are not allowed to store this information into database without consent I was thinking to anonymize ip address by removing first numbers and anonymize address by leaving just last 3 characters in the name and street name. Is that fine?
