DescriptionTamper-evident unrepeatable-pattern security principle demonstrated by securing a phone with rice patterns.ogv
English: When securing electronic devices, such as computers and smartphones, physically securing them to ensure no physical tampering, can sometimes appear to be difficult and/or expensive to do. However, using cheap and effective tamper-evidence mechanisms can induce such devices to be physically secured to the extent that after potential tampering has been detected, the devices can be repaired, reinstalled, or replaced (to overcome any tampering.) Strong tamper-evident mechanisms do not need to be expensive, and can even use household items that are also cheaply available, such as rice. This video demonstrates how rice can be used as such a tamper-evidence mechanism to secure a smartphone.

Rice patterns are hard to repeat, and can be exploited to provide tamper evidence, which is what this video seeks to demonstrate
