ASI invests in developing time stamp technology

Tallinn, October 30, 2006 – Experienced Estonian information security experts Märt Saarepera, Ahto Buldas and Ambient Sound Investments (ASI) established a joint company GuardTime which will develop technology for checking the data and date integrity of digitally archived content.

The goal of the joint venture is to develop a mass market technology that enables users attach a time stamp proving the creation time and the integrity of digitally archived documents. The stamp can be attached to text documents, tables, graphics, audio and video files.

"GuardTime's technology has multiple applications," said ASI CEO Toivo Annus. "For example, it can be used to prove when a detailed plan was accepted or the exact time when an audio recording was made. Similarly to physical documents also the need for verifying the integrity of digital documents is increasing."

According to GuardTime CEO Märt Saarepera the technology, once ready, will be offered in various markets. "Our goal is to produce the technology and offer time-stamping service first in Europe and Asia."

For now, ASI will hold a small percentage of the newly created joint venture. In the near future ASI will increase its commitment to GuardTime. "For ASI the investment in the seed-stage of this knowledge intensive technology is very interesting since our goal is to finance promising technologies at the seed stage," concluded Annus.
