Sandisk launches 'WORM'

In our digital age, fears of data being compromised is high in positions such as law enforcement and politics. Sandisk has released a solution for these woes, entitled "WORM". (Write Once Read Many=WORM).

These SD cards, currently available in only 128mb form, cannot be erased or modified once files have been put on it. Sandisk will be releasing higher capacity versions later this year.

Uses for this include police witness and suspect interviews, cash registers, electronic voting and really annoying yourself when you accidentally buy one down the shops and realise you can't use it again.

"As digital media volume has grown and surpassed traditional analogue 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.

I was using my windows XP disc yesterday but it was all scratched. May be the software vendors will find it useful to ship the S/W. most of the computers are now shipping with card readers and yea.. bootable too so I think it will be a good idea to scrap CDs and DVDs and start using this kind of media. IMO

This approach to security is well suited for some particular use, but not for users wanting a Read-only media. That is why CD and DVD are for in the first place.

However, with the speed and size of SD cards, this could be helpful for storing information that one don't need to delete/edit.

Umm a hammer anyone? If they really wanted to destroy the thing that badly they could just take a hammer and shatter it into a million pieces.

So, this is basically an EPROM chip, but with some kind of hardware-lock so it can only be written once? There's a market for this?

It is aimed to a corporate enviroment,practically everyone at neowin won't find it useful for personal purpose.

This is in fact an evolutionary product,in wich sandisk can find huge profit. And no it isn't an EPROM chip,it's a tech aimed at storage devices.howver i don't know what kind of tech they've put this in.

I think "WORM" is a bad name for this, the word "WORM" has been associated with too much malicious stuff. People will shy away from this.

Also like someone else said above, why are we re-inventing something that already exists?

CD-R with close disc session anyone?

Plus, I'm sure someone will reverse engineer the "lock" on it.

"WORM media" is not terminology invented by Sandisk - it's the right description for the product.

Also, CD-R's don't fit into cameras, as I believe that this is the targetted usage (ie: digital photos that can't be manipulated).

What the article completely fails to point out is that WORM media has been around for years; what it should say is that Sandisk are the first company to produce WORM SD cards (maybe also the first for any format of flash memory)

EPROM chips where kinda like WORM memory... they where writen to once but were also erasable under ultraviolet light

its not a software solution, its a hardware one.
Like trying to write twice on a CD that is not RW .. no amount of hackers will do.

So how exactly does this work? It seems like pretty much every type of protection technology gets hacked, bypassed, etc. What makes this any different?
