SanDisk has just announced that Japan’s police force has adopted its 1GB SD WORM memory card for collecting evidence. The Write Once, Read Many cards are tamperproof, can only be written to using a WORM-compatible device, and supposedly stores data reliably for 100 years. Practically speaking, this means that photographs and audio can be collected onto the cards, allowing those who access the data later on to be confident that it wasn’t tampered or edited in any way. The National Police in Japan have tested the technology extensively, and seem to be convinced of SanDisk’s claims.
We can’t really think of any practical application for ordinary photographers (can you?), but it’s interesting to know that this kind of technology is out there and being used.
