SanDisk Corporation announced today the introduction of a new digital memory card, the SanDisk SD WORM (Write Once Read Many). The card is designed for professional use, as for any application that requires data files to be protected against alteration or deletion, like police investigations, court testimony, electronic voting or others.
Conventional rewritable memory cards do not meet the legal requirements to prevent data
tampering, while other means of recording such data, like analog recording media (film and audio tape, for example), are becoming obsolete, so a more suitable solution for today's digital devices is required.
The SanDisk SD WORM cards provide such a way of recording data. All the files written on the device is locked down as soon as recording ends, eliminating any physical form of altering or deleting them. Reading the data is a simple task, because the WORM cards fit into any standard SD slot of a computer or other SD-compatible devices attached to it. If kept under appropriate storage conditions, the SanDisk SD WORM cards offer a 100-year archive life.
The cards can be used in applications like police photography and witness/suspect interviews, where courts require proof that photos and audio recordings are genuine, court proceedings, such as trials and depositions, electronic voting, where recorded votes must be tamper-proof, cash registers which record transactions for tax collection purposes, event recorders, like security cameras and "black box" flight-data recorders, medical devices which retain individual patient treatment data, personal digital assistants (PDAs) and similar devices used by physicians and other health-care professionals to track patient interactions.
"As digital media volume has grown and surpassed traditional analog media such as film and audio cassettes in the consumer market, law enforcement agencies and other professionals are facing rising costs and lack of supply," said Christopher Moore, director of product marketing for OEM memory cards at SanDisk. "SanDisk's new SD WORM cards offer professionals a one-stop solution for capturing and archiving critical data, along with many other benefits of moving from analog to digital."
When used in the photography area, these cards eliminate the costs and delays brought by film processing or scanning negatives to store them as digital files. Since they have no moving parts, and no tapes that can tangle and break are used, they will also be more reliable in the voice recording area. Another important feature is the possibility to store different types of data (like texts, photos, voice recordings) on a single lasting device.
The company is working now with different digital device manufacturers for the creation of the appropriate firmware that will enable the recording to SanDisk SD WORM cards. SD Card Association has also been approached for the approval of the new specification as an industry standard.
SanDisk SD WORM cards' third-party resellers are enabled to develop security enhancements for the devices, including password protection and encryption. SanDisk is also working on an enhancement for the cards, the addition of TrustedFlash security technology, which securely stores sensitive digital data and applications on digital media.
The SanDisk SD WORM cards have been made available worldwide in the 128-megabyte capacity. The company plans to release them on higher capacities by the end of the year.
