Students at Hong Kong's Chinese University may be onto a type of memory media that could be a truly secure way to store data -- text, images, music, and video. It takes up almost no space, can be encrypted, and is so gross that it's unlikely many people would attempt to steal it. That is, if the thief would even consider searching a refrigerator for massive data storage inside E. Coli -- the bacteria responsible for 90% of urinary tract infections, which can cause food poisoning and is the reason for many food recalls. The bacteria can successfully and securely be used for biostorage, the storage of data in living things. According to an AFP report, the U.S. national archives take up more than 500 miles of shelves, but one gram of bacteria used for storing data could hold the same amount of information as 450 hard drives with 2,000 gigabytes (2 TB) each of storage capacity. "This means you will be able to keep large datasets for the long term in a box of bacteria in the refrigerator," said student instructor Aldrin Yim about the biostorage project. Also according to Discovery News, another student instructor, Allen Yu said, "Bacteria can't be hacked. All kinds of computers are vulnerable to electrical failures or data theft. But bacteria are immune from cyber attacks. You can safeguard the information."
