Sign On to a PC with a Palm

CIC's Sign-On for Palm has long allowed users to make their handheld accessible only to someone whose signature matches the owner's. Today they released Sign-On for Windows, which allows files on a Windows PC to be locked and opened by a signature written on a Palm.

Individual files or groups of files can be selected and locked or unlocked by with a signature on the handheld located in the cradle.

When a signature is entered, the software records and measures the speeds, rhythm, patterns, habits, etc., unique to the individual. These measurements are different for each signer based on the qualities and characteristics of their handwriting. Because they are unique to each individual, the underlying biometrics of the handwritten signature can be used to verify the authenticity of the signature and therefore the identity of the individual signing their name.

Each file is protected by a signature, so a single user or multiple users can protect different files. The signature is stored within the file as part of its contents. The same signature is required to open the file. This means that the file is always secure even if it is moved to another computer.

All signature data and templates and the file to be secured are encrypted for secure storage using Triple DES algorithm.

This can be used with Palm handheld running OS 3.3 and above with serial or USB connection. A handheld isn't required. Wacom Graphire or Interlink ePad tablets will also work.

Sign-On for Palm costs $20. Sign-On for Windows costs $40 and is available as a bundle with the Palm version, also for $40.
