An Internet pioneer will discuss technology's effect on privacy during two free lectures at California Lutheran University.

David H. Holtzman will speak on "Privacy Lost - How technology affects privacy" at 10 a.m. Monday, Nov. 5, in Samuelson Chapel. He will discuss what he considers one of society's greatest challenges over the next 25 years - reconciling desirable advances in information technology with respect for the individual. The lecture will address whether people should try to regulate intrusive technology, find new ways to protect themselves or redefine the idea of privacy.

At 4 p.m., Holtzman will give a lecture titled "Online Identities: @ttribution, not retribution." He will explore the ways the Internet has changed the definitions of privacy and personal identity since the network allows people to create multiple personas and express ideas under pseudonyms. Holtzman will explain how people should preserve their privacy and protect their identities in the absence of comprehensive legal protection.

The Virginia resident is a former security analyst and military code-breaker who helped oversee the Internet's growth from its infancy in the mid-1990s through the dot-com boom. As manager of the Internet's master root server, he supervised the increase in the number of domain names from 500,000 to more than 20 million.

Holtzman is an expert on the technological implications of global networks and their effects on society. He founded a firm called GlobalPOV to explore significant technology issues, and he publishes a daily blog on topics such as intellectual property, business and pop culture at www.globalpov.com. The author of the 2006 book "Privacy Lost: How Technology is Endangering Your Privacy," Holtzman is quoted widely by major news media and has had essays published in Business Week, Wired and other magazines.

The talks are part of the 22nd annual Harold Stoner Clark Lecture Series, endowed by the late university supporter and sponsored by CLU's Philosophy Department. Clark had requested that the lectures address his dual interests of science and philosophy.

CLU is located at 60 W. Olsen Road in Thousand Oaks.
