How Does Blockchain Secure Medical Images?
Healthcare facilities handle millions of medical images every year. X-rays, MRIs, CT scans—all of them need to be stored, accessed, and tracked. But here's the problem: medical image archiving software can be vulnerable to tampering. Someone could alter an image, delete access logs, or change timestamps without anyone knowing. Blockchain technology solves this by creating records that can't be changed once they're written. What Makes Blockchain Different from Regular Databases? Regular databases let administrators modify or delete entries. You can change a timestamp, remove an access log, or edit who viewed a specific image. This creates problems when you need to prove what happened in legal cases or regulatory audits. Blockchain works differently. When someone accesses a medical image or makes any change, the system creates a permanent record that gets locked into a chain of data blocks. Each block connects to the one before it using complex math called c...
