How do you make sure that data you received has not been tampered with? How do you verify that your source of data is indeed who he says he is?
These are just two of the most important security questions that the SecurDisc technology is trying to address, and CD-burning software provider Nero is incorporating the feature in its April update of its Nero 7 software.
The SecurDisc data protection technology aims to protect the security and integrity of data written on writable optical media. It protects data from illegal access and alteration by applying a digital signature, while at the same time protecting data from physical damage and degradation. It allows verification using the optical drive itself.
Already, Nero and optical drive manufacturer LG Electronics are integrating SecurDisc in their products, and are planning to license the technology to other users.
