The new encryption software will allow users of the Microdrive hard drives to use the same drive in different mobile devices without having to reconfigure its security settings. The drive will offer up to 1Gbyte of storage for mobile devices, the company said.
PDASecure is a software product that can distinguish between differing encryption formats in mobile devices, and allow for that data to be transferred from device to device without losing the encryption protection or requiring the user to re-encrypt the data after transferring it, said Kevin Shahbazi, vice-president of marketing for Trust Digital.
"Users don't want to go through complicated security procedures, so PDASecure allows security policies to be managed from a central location," said Shahbazi.
The software can be used on any type of mobile device, including laptops, PDAs, digital camera, and others, he added.
The software targetes large enterprise customers who use PDAs and must protect the data contained in those devices, such as government agencies and hospitals.
For example, nurses at a hospital could have patient records uploaded to their Microdrive overnight, and then transferred via the Microdrive from a central PC to their PDA when they arrive in the morning, providing them with a detailed list of patient information for their daily rounds.
US federal regulations require that personal information stored by health-care providers be secured.
PDASecure can encrypt some or all of a user's files by converting the files into ciphertext, which is unreadable unless unlocked through a username and password, the company said. The encryption process was derived from a military-grade security algorithm developed by the company, Shahbazi said.
The software works on devices running Palmsource's Palm OS, and Microsoft's Pocket PC and Windows CE operating systems, said Shahbazi. A version for Research in Motion's Blackberry devices will be released by the end of the month, he added.
PDASecure is available worldwide. Large enterprises will pay $79 (£55) for a single licence and $999 (£695) for the server-side software package. Single users can buy the software to encrypt their personal Microdrives for $29.99 (£21), the company said.
