Locks: Physical vs. Digital Security Challenges

  • Physical locks are not as secure as perceived, as they can be easily bypassed with tools and time, making the appearance of security more important than actual security in normal life.
  • Digital locks, on the other hand, face a different challenge as they must protect against cyber threats globally, with hackers using bots to try millions of combinations to breach security.
  • Encryption is the solution for digital security, creating unbreakable locks that require secure passwords to access, making it nearly impossible for hackers to breach.
  • Governments are considering legal measures to ensure access to digital devices in cases of emergencies, proposing the inclusion of keyholes in digital locks for police access, despite the challenges of banning unbreakable digital locks due to their mathematical nature.
