June 2, 2003—Transaction Security Inc., a developer of productivity software solutions, has released its PDA-Protect biometric software. The first product based on the company’s patent-pending Crypto-Sign technology, PDA-Protect provides biometric access control to personal digital assistants—including Windows-powered Pocket PC devices with phone and wireless capabilities—without additional hardware requirements.
Crypto-Sign is based on the submission of a secret sign—rather than a human signature—on a PDA, Tablet PC, or digitizer. The position of the user’s stylus is sampled many times a second as it moves over the surface to generate data, which are analyzed and compared with a previously established template. For device access control, Crypto-Sign can be used to release electronic signatures to documents for proof of authorship and to generate encryption keys. The sign is never displayed on the device, significantly reducing the risk of fraudulent access.
Details and software downloads are available online at the Crypto-Sign Web site.
